Material Handling and Storage

• Store rolls upright on pallet in dry area.

• Store indoors in a ventilated area.

• Keep rolls protected from exposure to heat, sun,

cold and moisture.

• Do not double stack pallets.

• Do not store rolls on their sides.

• Use care in the handling of the rolls.

• Do not overload the roof. Stagger the rolls across

the roof. Avoid excessive weight in a concentrated

area.

Weather Precautions

Do not attempt application if weather conditions and

substrate are not dry.

Do not attempt application if ice, frost, moisture or snow is present.

Rolls can be installed in cold weather if conditions are dry, the rolls have

not been allowed to freeze and proper cold weather handling and storage

procedures are followed. Store rolls in a heated area until just prior to use

and do not proceed with installation if rolls have been allowed to freeze or

weather conditions are unsuitable.

In extremely warm weather, use caution when walking on freshly installed

material to avoid “tracking” warm asphalt; when torch applying smooth

APP membrane in very warm weather the installer may want to utilize a roll

puller and work from front side of the roll (as is the standard torch method

for SBS membranes) to avoid tracking.

Roof Slope and Drainage

The roof surface that is to receive the roof membrane shall have slope to

water collection devices. A drainage calculation determining the quantity of

water that will fall on the roof and how it is to be taken off the roof is a part

of good roof design. Model building codes and good rooﬁng practice have

established a minimum slope for roofs at 1/4":12 running inches. Codes also

recognize the challenges to meet this criterion in rerooﬁng of existing

buildings. All roof areas shall be designed and installed to drain without

holding water on the roof surface. Water collection on the roof surface can

be detrimental to the roof membrane and may void an existing warranty.

Water should not pond in drain sumps or any other collection area that is

covered in roof membrane. Limited and minor areas of ponding may be

accepted by CertainTeed under the terms of the warranty; however,

sacriﬁcial surfacing may be required to maintain the warranty.

All roofs shall have an overﬂow system adjacent to drains or scuppers to

collect and direct water off the roof should one or more water collection

device fail. Overﬂows are required by most local building codes and should

be incorporated into any roof design.

Substrate Preparation

All surfaces to which the Flintlastic modiﬁed bitumen is to be installed must

be smooth, dry, free from dust or debris, free from settling or distortion, and

free from cracks, knotholes, or other defects.

Primer

Concrete decks must be properly primed with suitable asphalt primer

(meeting ASTM D-41) and the primer must be thoroughly dry.

FlintPrime SA, water-based primer is recommended when installing

self-adhering systems.

Metal ﬂashings must also be primed with a suitable asphalt primer for

metal, and primer must be thoroughly dry and any solvents evaporated

prior to application of membrane ﬂashing.

Base Sheet Application

In new construction or re-rooﬁng applications, an appropriate CertainTeed

base sheet must be installed over the substrate. Unless otherwise

speciﬁed, base sheet must be overlapped min. 4" at endlaps and 2" at

sidelaps. For mechanical attachment of the base ply on insulated steel

substrates, the base sheet at a minimum may be fastened with approved

fasteners 12" o.c. on 4" side laps and 18" o.c. in two staggered rows in the

ﬁeld of the sheet 12" in from the edge.

For nailable substrates, base sheet must be mechanically fastened in

accordance with NRCA standards (fasteners placed every 9" o.c. at

sidelaps and every 18"

o.c. in two staggered

rows in the ﬁeld of the

sheet; the two stag-

gered rows are placed

12" from each sidelap).

For non-nailable sur-

faces, spot mopping

with hot asphalt at the

minimum rate of one

12" circle every 24" o.c.

in all directions, using

appropriate type

asphalt at the

minimum rate of 15 lbs. per square, is the standard spot mopping method.

Refer to www.roofnav.com for speciﬁc information regarding Factory Mutual

requirements, which may differ per individual speciﬁcation. Refer also to the

“Hot Asphalt Application” section on page 30 of this booklet.

Vapor Retarders

Refer to the General Recommendations Section of the CertainTeed

Commercial Roof Systems manual for more information.

Insulation

All insulations require the use of appropriate base sheet between the

insulation and the new roof system. Insulations must be installed in

accordance with CertainTeed’s instructions, local code and Factory Mutual

requirements.

In general, the following rigid board insulation types are acceptable for use

under Flintlastic modiﬁed bitumen Roof Systems (consult CertainTeed for

speciﬁc Factory Mutual requirements):

Fiberglass or mineral wool

Conforming to ASTM C726 (CGSB 51.31M)

Wood ﬁberboard

Conforming to ASTM C208 (CGSB 51.26M)

Perlite

Conforming to ASTM C728

Extruded polystyrene*

Conforming to ASTM C578-85-Type IV (CGSB SB-51.20M Type 2-Type 4)

Expanded polystyrene*

Conforming to ASTM C578, Min. 1.1 Density (CGSB 51.26M)

Polyisocyanurate

Conforming to ASTM C1289 Type II.

*Expanded polystyrene and extruded polystyrene insulations require a coverboard prior to installation of base sheet.

Additionally, taping of insulation joints may be required. Refer to NRCA and CertainTeed requirements. CertainTeed

self-adhered base sheets may be directly adhered to mechanically attached, ﬁber glass faced isocyanurate insulation

such as FlintBoard ISO cold. Do not expose ﬂammable or heat sensitive insulations to heat, solvents or ﬂame.

Multi-layer Insulation Applications

To reduce thermal stress to the roof membrane, multi-layer applications are

strongly recommended. Joints in the insulation layers should be staggered

a minimum of 6" and joints should be tightly butted. Where mechanical

fasteners are used, only the base layer should be mechanically attached.

Subsequent layers should be installed in asphalt or adhesive.

The insulation or coverboard surface used for the installation of membrane

shall be planar and free from debris. Any gaps shall be corrected prior to

application of membrane. No insulation or coverboard panels should

be less than 12" square when adhered or 24" square when mechanically

attached.

Mechanical Attachment

All base insulation layers over steel deck shall be mechanically attached

with sufﬁcient fasteners and stress plates to meet the uplift requirements

for the project. Fastener density shall be increased at perimeters and

corners as required by code and the project requirements. At a minimum,

fastener density shall be increased by 50% at the perimeters and 100% at

the corners, providing there is no parapet with a height less than 36".

Fasteners shall penetrate the top ﬂange of the deck a minimum of 3/4".

To ensure securement to the deck, fasteners shall be sized to

penetrate the bottom ﬂute by 3/4". Fasteners shall be fully seated but

shall not be overdriven to damage the insulation or coverboard surface.

Fasteners and stress plates shall be installed in compliance with the

recommendations of both the fastener and insulation manufacturers.

Where holes must be predrilled, such as gypsum and concrete, deck

debris must be cleaned from the insulation surface prior to application of

the rooﬁng membrane. When projects are insured by or speciﬁed under the

requirements of FM Global the requirements under the relevant RoofNav

number and the related Loss Prevention Data Sheet shall be followed.

For more information, visit www.roofnav.fmglobal.com/.

CertainTeed provides a complete line of FlintBoard roof insulations and

reserves the right to accept or reject another manufacturer’s insulation

as an acceptable substrate for attachment of a CertainTeed Commercial

Roof System. CertainTeed Corp. does not warrant performance of another

manufacturer’s insulation unless such approval is granted in writing by

CertainTeed in advance of installation.

Recover Considerations

A recover is the application of a new roof over an existing roof. If a roof

installation is a recover, the existing roof assembly must be a suitable

substrate for the application. Most codes limit recovers to one additional

roof. An evaluation of the combined live and dead loads should be carried

out by a structural engineer prior to any application over an existing roof.

Loading requirements may have changed since the original roof application

increasing the live load requirements due to historical snow loading data.

The existing roof should be evaluated for moisture and for adhesion to the

underlying substrate. Adhesion can be evaluation with either a vacuum test

or bonded pull test as detailed in the FM Global Loss Prevention Data Sheet

1-52 or the vacuum test detailed in the ASTM E 907

. Moisture analysis can

ASTM E 907: Standard Test Method for Field Uplift Resistance of Adhered Membrane Roofing Systems

be either nuclear, capacitance or infrared. All wet rooﬁng materials must be

removed prior to any recover.

Should the existing roof be used as a bonding substrate, the surface must

be properly prepared for the application of the new roof or insulating layer.

Loose and large gravel shall be removed; blisters and splits shall be

repaired and existing ﬂashings should be removed to create a clean

bonding surface for new elements. Where the new roof is mechanically

attached to the underlying substrate, withdrawal resistance testing should

be carried out to conﬁrm the attachment values for each fastening point.

Testing should be carried out in compliance with ANSI/SPRI FX-1-2006

or TAS 105. Copies of the test protocols are available from CertainTeed

Technical Services. Fastener values should meet or exceed 325 lbf or the

fastener density should be increased. The test data shall be evaluated

by the roof designer of record for the evaluation of the fastening pattern.

CertainTeed Technical Services can provide test data for a wide variety of

system to assist in the evaluation.

Areas of ponding shall be corrected prior to the installation of a recover

roof. Fillers designed to ﬁll low spots should be used to correct these

conditions. For a list of available products, please contact CertainTeed

Technical Services.

It is the responsibility of the designer of record, and/or building owner to

determine whether an existing roof is structurally sound, ﬁrmly attached,

dry and suitable for recover. CertainTeed Technical Services can provide

additional warranty information for speciﬁc recover projects.

Preparation and Field Conditions

The following requirements shall be used in conjunction with good rooﬁng

practices to qualify a new assembly for the NDL Limited Warranty or the

Limited Product Warranty Program:

1. Deck shall be dry, structurally sound and suitable for the application of

the roof assembly.

2. Parapet walls, perimeter edges, equipment and load bearing supports,

platforms, curbs, etc., shall be structurally sound and suitable for the

application of the ﬂashings and terminations.

3. Existing roof assemblies should be evaluated to determine if additional

expansion or control joints are needed. Visual observations of wall

cracks, membrane splits and materials out of plane are indicators of

such conditions.

4. The designer of record should evaluate combined live and dead loads to

insure the recover roof assembly meet current code criteria and sound

engineering practice.

5. Existing plywood decking shall have adequate bearing or support of

end joints. In recover applications, remediation of the joints can only be

achieved from the underside of the deck.

6. All recover roofs shall have positive drainage as deﬁned on page 9.

7. Existing roof insulation shall be dry and ﬁrmly attached. Where existing

insulation is found to have insufﬁcient attachment, attachment of the

existing system shall be enhanced.

8. Existing roof system shall be compatible with new roof system.

9. Existing membrane shall be dry and clean with all surface defects

corrected.

10. Existing roof surfacing with 1/2" or larger aggregate surfacing shall

be torn off or spudded to provide a smooth surface. Notwithstanding

the gravel sizing, all loose gravel shall be swept from the existing roof

surface.

11. Remove existing metal gravel stops and other termination ﬂashings and

replace with new metal to meet current code. Flashing metals shall be

corrosion resistant and shall not be thinner than 24 ga.

12. Existing counterﬂashings, copings, dunnage protectors, protective caps

and other ﬂashing metals designed to protect the roof shall be replaced

where unsuitable for reuse. New metals shall be corrosion resistant

and shall not be less than 24 ga.

13. Remove all clamping rings from drains and clean to bare metal.

Damaged drain components shall be discarded and replaced with new.

When in good condition, clamping rings may be saved for reuse. All

bolts shall be replaced with new, preferably formed from non-ferrous

materials. Stripped bolt holes shall be drilled and tapped. All drains

shall be fully secured to the deck with under deck clamps or other

factory supplied clamping systems.

14. All abandoned and non-functioning equipment shall be removed.

Any resulting deck opening shall be blocked and closed with

appropriate decking.

15. Flashing heights shall be a minimum of 8" from the surface of the roof

membrane. Where ﬂashing terminations may be subjected to snow

cover, the ﬂashing shall be sealed.

16. Base and wall ﬂashing shall be removed to create a sound surface for

the installation of new ﬂashings.

17. All roof penetrations require all new ﬂashings in compliance with current

CertainTeed detailing.

18. Equipment vibration shall be corrected.

19. Masonry surfaces above ﬂashings shall be tuck-pointed and sealed.

All horizontal masonry surfaces above the roof membrane shall be

adequately protected from weather.

20. All pipes and condensation line supports shall be properly supported

with factory supplied pipe supports or pressure treated woodblocking.

All supports shall have a protection layer of not less than one layer of

Flintlastic modiﬁed bitumen membrane. The support shall be designed

to allow for pipe movement and shall not be secured through the roof

membrane.

21. Condensation lines shall be formed from ultraviolet light resistant

materials and shall terminate at drains or scuppers. Condensate shall

not run on the roof surface.

22. The practice of installing only a part of a total roof assembly, known

as phasing, can be harmful to the ﬁnished roof assembly. CertainTeed

will not warrant phased applications.

NOTE: Substrates with two or more existing membranes are not

eligible for a CertainTeed Warranty. Extended warranties require

new construction and/or complete tear-off.

Application Over an Existing Membrane

After preparing and priming the existing membrane surface spot mop with

type III or type IV asphalt, forming 12" circles spaced 24" o.c., and install

a Yosemite Venting Base Sheet with side laps of 2" and end laps of 6".

Asphalt quantity shall be 15 lbs. per square, or greater, depending on the

roughness of the existing membrane surface. Granules and grooves shall

be facing down. Alternatively, mechanically attach a Yosemite Venting

Base Sheet with minimum #12 diameter rooﬁng fasteners and 3" stress

plates to meet the design uplift criteria. At a minimum, mechanical

attachment shall be placed 12" o.c. on a 3" lap and two staggered rows

in the center of the sheet spaced 18" o.c.

Insulation shall be solid mopped to buffer sheet. Alternate base sheets may

be approved on a job-by-job basis. Contact CertainTeed Technical Services

with project data for consideration of alternate base sheets. Rigid insulation

may be applied directly to an existing built-up membrane providing the

surface has been properly prepared; there is adequate attachment of

the existing roof assembly to resist design and/or code require loads and

the deck has been adequately leveled to provide full adhesion of the

maximum 4' x 4' insulation boards. An initial glaze coat of asphalt can ﬁll

minor variations in the deck surface and provide a more suitable surface for

the application of rigid insulation board.

Roof Relief Vents

If roof relief vents are deemed appropriate they should be of a suitable type

with minimum 4" ﬂange and weather resistant hood, spaced 20' from roof

edge perimeter and every 40' o.c. thereafter.

Proper Tools

To the professional roofer, the importance

of proper tools is understood. However,

here’s a brief recap of the ideal tools for

applying Flintlastic modiﬁed bitumen:

• For torch applications, a U.L. listed

torch designed speciﬁcally for the

application of modiﬁed bitumen

membrane with U.L. listed high-pressure

hose, and U.L. listed regulator. Use an

appropriate length ﬁeld torch for applying

the ﬁeld roof membrane, and a “detail” torch for accomplishing

ﬂashing details.

• Propane tank with pressure gauge.

• At least one ABC type re extinguisher, fully charged (min. 20 lbs.) per

each operating torch and the appropriate number of ﬁre extinguishers at

the kettle area if hot asphalt is used.

• For hot asphalt applications, appropriate asphalt heating, handling and

application equipment. Mop size should be not less than 32 ounces.

• For self-adhering applications, 18" wide, 2"– 4" diameter industrial steel

roller for pressing membrane into place; long-handled (standing) roller

with 1/8" –1/4" nap for applying primer (1/8" nap for smooth surfaces,

1/4" nap for more porous surfaces); caulk gun for applying beads of

FlintBond adhesive; hand-held hot air welding gun such as the Leister

Triac™ (110 volt power required) or Primus Sievert PNS-4™ Hot Air Kit;

seam probing tool to check for small voids.

• A roofer’s hooked blade knife (the hooked blade is ideal for cutting the

membrane).

• A roofer’s trowel with beveled edges and rounded tip (allows smoothing

of details without cutting or marking the membrane); trowels that allow

adequate room between the roofer’s gloved ﬁngers and the warm

membrane are the best.

Proper Attire

• Long pants and long sleeved shirts.

• Leather work shoes with synthetic or smooth leather soles.

• Leather work gloves that adequately shield the wrist area. Refer also

to the “Safety” section on page 53 for information regarding proper

work attire.

Roof Layout

As with most types of roof installations, Flintlastic modiﬁed bitumen

roof installation begins at the low point of the roof with successive rolls

installed so that no laps are against the ﬂow of water. When membrane

is applied with hot asphalt, where roof slope is 1" per foot or less, sidelaps

are installed perpendicular to the direction of the roof slope. In situations

where the roof slope exceeds 1" per foot, rolls are installed with the

sidelaps running parallel to the slope direction. APP modiﬁed membranes

can be installed with sidelaps perpendicular to the slope where roof slope is

2" per foot or less (over 2" install sidelaps parallel to roof slope direction).

Additionally, where roof slope exceeds 1" per foot for SBS modiﬁed and

self-adhering membranes or 2" per foot for APP modiﬁed “back-nailing”

of membrane is required. Refer to the General Recommendations section

of the CertainTeed Commercial Roof Systems Manual for back-nailing

guidelines.

Endlaps are to be staggered. In multi-ply applications, membrane sidelaps

must also be staggered.

In multi-ply systems, stagger sidelaps from Stagger ﬁeld sidelaps from

interply and base sheet sidelaps base sheet sidelaps

Warning: Flintlastic Modiﬁed Bitumen application may require the use of

hot asphalt and/or an open ﬂame rooﬁng torch. Improper application

practices may cause physical injury to the applicator or damage to the

property. Refer to the current CertainTeed Commercial Roof Systems

Manual for further information.

Basic Application: Flintlastic APP Modiﬁed Bitumen

Prepare the substrate as described on page 10. Flintlastic APP modiﬁed

bitumen must be applied using a professional roofer’s torch. Use of

hand-held rooﬁng torches is recommended and affords the most control.

If multiple burner torching machines are utilized care must be taken to

assure uniform heat application and to avoid overheating of the membrane.

Begin membrane application by

unrolling the roll and aligning the

sidelaps. Re-roll the roll halfway.

Standing on the unrolled portion to

prevent shifting, begin torching the

exposed polyethylene side of the

rolled portion. Walk forward as

you torch, pushing the heated coil

forward and into place with your boot.

Proper torching procedure involves passing the torch ﬂame in an “L” pattern

across the coiled portion of the roll and up the sidelap area. As subsequent

rolls are installed, heat is applied both to the roll and the exposed laps of

the membrane being overlapped onto. As it is heated, the roll becomes

shiny and the polyethylene ﬁlm melts away. Adequate heat is conﬁrmed

when a uniform ﬂow of melted bitumen compound ﬂows evenly in a

1/4" –1/2" uniform bead that oozes from the applied membrane’s edges.

Be sure to heat the entire roll evenly, not just the lap areas, with extra

concentration at the laps. Once at the end of the roll, re-roll the untorched

half, pulling back to beyond the starting point as much as possible, and

repeat the torching procedure.

Proper torching, in an “L” pattern, assures uniform 1/4" –1/2" compound

and ﬂow at laps and adequate heat across the coil

Trim the lower outside corner of the roll at an angle as shown. Overlap

subsequent rolls 3" at sidelaps (or as speciﬁed, min. 3") and 6" at endlaps.

Sidelap lines are generally indicated for the applicators’ convenience.

Overlap Flintlastic STA sidelaps a minimum of 3"

Trim the upper outside corner of the subsequent rolls as shown. All trimmed

corners will be covered with the subsequent rolls.

Endlap cuts are made at an angle as shown

It is critical (especially at the lap areas) to apply adequate heat to both the

membrane being installed and the area of membrane being overlapped

onto. Granuled APP membranes require treatment of the underlying lap

granules by heating and removal or heating and pressing to insure a proper

end lap weld. A warm trowel should be used to check laps for an adequate

seal. Any unbonded areas must be lifted and retorched. Do not attempt to

reseal by torching the top surface of the membrane.

Flashing Details: Flintlastic APP Modiﬁed Bitumen

Flashing details are accomplished using cut pieces of Flintlastic APP

modiﬁed bitumen in combination with appropriate prefabricated ﬂashing

components. The same sidelap and endlap rules apply to ﬂashing

details as to ﬁeld membrane.

Examples of typical ﬂashing

details are as follows:

Parapet Wall

Noncombustible cant strip must

be installed at the base of the

parapet wall. Field membrane

plies must extend a minimum of

2" beyond the top of the cant strip.

For nailable walls, appropriate

base sheet must also cover

parapet wall and extend to the top

of cant strip. Base sheet extends

over the top of parapet and is

mechanically fastened.

Parapet wall ﬂashing membrane

Concrete wall with metal counterﬂashing

(Flintlastic APP modiﬁed bitumen)

not exceeding roll width must

extend to the outside edge of the

parapet wall if coping is used,

or a minimum of 8" above the top

of the cant strip if termination bar

and counterﬂashing are installed,

and a minimum of 4" onto the

completed ﬁeld membrane.

Wood parapet wall with metal coping

Parapet Inside Corners

Base of corner: Make a “V”-shaped cut in the Flintlastic APP modiﬁed

bitumen membrane to permit it to conform to the inside corner fold (both

sides of the “V” will neatly overlap when folded into the corner). Use a trowel

to press the heated membrane ﬂaps into place. Top of corner: Cut a notch

part way to permit the top of the membrane to conform to the inside corner

and fold over the top of the parapet. Cap the resulting gap with a strip of

Flintlastic APP modiﬁed bitumen.

Outside Corners and Curbs

At outside corners such as

curbs, the reverse situation

occurs from that of inside

corners. The “V”-shaped

cut goes at the top of the

membrane strip and the notch

or straight slice at the bottom,

since the membrane is folding

the opposite way.

In this case, cap the opening at

the bottom of the strip which

extends onto the ﬁeld of the

roof a minimum of 4"

Note: Completed ﬁeld

membrane shall be extended

2" above top edge of cant

and solid attached to cant

strip only.

Metal Edge Detail – Mineral Surfaced Applications

Base sheet must extend over fascia a min. of 2". A min. 9" wide strip of

ﬂashing membrane (Flintlastic APP modiﬁed bitumen) should then be

applied to the base sheet,

ﬂush with the roof edge and

extending 9" onto the ﬁeld of

the roof.

Appropriate edge metal

(min. 26 gauge, primed)

must be properly installed

and secured (in two rows,

spaced every 6" staggered,

fasteners placed every 3").

Finally the mineral surfaced

installed and secured.

A min. 10" wide strip of

A strip of Flintlastic APP modiﬁed bitumen large enough to extend a min. of

4" beyond the lead ﬂashing edge in all directions (min. 40" x 40") is applied

to the base sheet at the drain area. A min. 30" x 30" lead ﬂashing is installed

next. Over the primed ﬂashing the ﬁeld roof membrane is applied in normal

fashion. The drain opening should be cut out while the membrane is still

warm and the edges sealed. Lead ﬂashing is peened ﬂat against drain bowl

sides. Set the drain cap in place and secure the clamping ring. If two ﬁeld

plies of Flintlastic APP modiﬁed bitumen membrane are used, the ﬁrst ﬁeld

ply takes the place of the 40" x 40" ﬂashing ply.

Vent Pipes

Position the smooth Flintlastic ﬂashing on a piece of membrane and mark

the dimensions of the vents. Cut a hole corresponding to the pipe size so

that a snug ﬁt is achieved. The membrane strip must be large enough to

extend a min. of 4" beyond the outside edge of the vent pipe ﬂashing ﬂange

in all directions. Heat the underside of the membrane strip and press into

place. Install the vent pipe collar and secure 3" o.c. around perimeters.

Over this the Flintlastic ﬁeld membrane is applied. Seal the base of the

pipe collar with melted modiﬁed bitumen.

Scuppers

The scupper ﬂange is

positioned between the base

ply and the Flintlastic ﬁeld

membrane, securely

fastened. The ﬁeld base ply

extends a min. of 2" above the

cant strip. The parapet wall

base ply extends from the top

outside edge of the parapet

over the ﬁeld base ply to the

top of the cant strip, securely

fastened. Install scupper,

securely fastened 3" o.c., in a

bead of sealant. The ﬁeld ply

or plies (on top of the scupper

ﬂange) also extend a min of 2"

Scupper detail, torch applications

above the cant strip. Cut out scupper opening as necessary. Field mem-

brane is fully adhered and edges sealed. Over this, install a cap of fully

adhered Flintlastic APP modiﬁed bitumen membrane that covers the top

of the parapet and extends down the parapet wall and a minimum of 4"

onto the ﬁeld of the roof. Secure membrane 9" o.c. through tin discs along

top of parapet. Again, cut out scupper opening and seal membrane edges.

Install parapet wall metal coping.

Basic Application: Flintlastic SBS Modiﬁed Bitumen

Prepare the substrate as described on page 11. Flintlastic SBS modiﬁed

bitumen can be applied in either hot asphalt, cold SBS modiﬁed bitumen

adhesive or using a professional roofer’s torch. Do not use hot asphalt or

cold adhesive for applying polyethylene backed Flintlastic SBS modiﬁed

bitumen (use torch application method).

Hot Asphalt Application

Rooﬁng asphalt shall conform to ASTM D-312 Type III (slopes up to 1"/ft.)

or Type IV (slopes up to 3"/ft.) Asphalt must not be heated to or above

the actual ﬂash point. Asphalt should not be heated and held above the

ﬁnished blowing temperature

for more than 4 hours.

All moppings shall be

uniform and free from voids.

Bitumen temperature shall

be at the Equiviscous

Temperature (EVT) ±25°F,

at the point of application

(minimum 425°F). EVT is

deﬁned as the temperature

at which asphalt attains

the proper viscosity for

application (this information

is typically found on the

product labeling).

Adequate heat at the point

of application is critical to proper

adhesion of the membrane plies. Apply asphalt uniformly and evenly

without voids; a small bead of asphalt should be visible at all lap areas.

Solid moppings require a min. of 25 lbs./100 ft

hot asphalt application.

Spot mopping of base sheet, when appropriate, is generally accomplished

using a minimum of 12" diameter circles spaced every 24" o.c. in three

staggered rows. (Certain Factory Mutual listed speciﬁcations may have

different requirements; refer to www.roofnav.com for complete details).

Modiﬁed Bitumen Cap Sheet

Excessive, prolonged heating of asphalt can have a detrimental effect on

the integrity of the product. Additionally, excessive heating of asphalt poses

a serious ﬂash or ﬁre hazard. Refer also to the “Safety” section beginning

on page 52 of this handbook for more information.

The following chart shows guidelines for heating of asphalt by type (Type III

and IV):

NRCA published guidelines regarding heating

and slope restrictions for mopping grade roof asphalt

ASTM D312 Type Mopping Temp. Heating Temp. Maximum Slope*

Type III 425° F+/-25°F 500°F ≤ 1"

Type IV 425° F+/-25°F 500°F ≤ 3"

*CertainTeed recommends use of Type IV asphalt for interply moppings regardless of slope

Cold Adhesive Application

FlintBond SBS modiﬁed bitumen adhesive shall be used to apply Flintlastic

SBS modiﬁed bitumen membranes, Flintglas Cap sheets and coated base

sheets. FlintBond shall not be used with APP and SBS modiﬁed bitumen

membranes designed for torch applications or Flintglas ply sheets.

Flintlastic GMS can be applied using FlintBond SBS Modiﬁed Bitumen adhesives

(squeegee method shown)

Strict attention must be paid to weather and climate limitations, application

method and technique, curing time, application rates (gallons/100 ft

handling and storage. These requirements are outlined in the technical data

sheets. Proper squeegee or spray equipment must be used. Do not use

modiﬁed bitumen adhesives in areas without proper ventilation.

Membrane application requirements such as endlap and sidelap widths,

number and order of plies and ﬂashing details are the same for both hot

and cold applications.

Interply or Mid-ply Application

If the Flintlastic SBS modiﬁed bitumen speciﬁcation calls for interply layers,

begin membrane application by unrolling the roll and aligning the sidelaps.

Re-roll the roll halfway. Standing on the unrolled portion to prevent shifting,

begin hot asphalt application* to the substrate at the rate of 25 lbs./100 ft

Do not apply asphalt more than 6' in front of the roll at any time to prevent

premature cooling. Overlap subsequent rolls with appropriate sidelaps and

endlaps as speciﬁed in the CertainTeed Commercial Roof Systems Manual

for the Flintlastic SBS modiﬁed bitumen product being used.

Cap Sheet Application

Begin Flintlastic SBS modiﬁed bitumen membrane cap sheet application by

unrolling the roll and aligning the sidelaps. Re-roll the roll halfway. Standing

on the unrolled portion to prevent shifting, begin hot asphalt application*

to the substrate at the rate of 25 lbs./100 ft

. Do not apply asphalt more

than 6' in front of the roll at any time to prevent premature cooling.

Overlap Flintlastic Cap sheet endlaps a minimum of 6"

(Note: cut endlap corners as shown on page 20)

Overlap subsequent rolls with 3" sidelaps and 6" endlaps. Cap sheet

sidelaps must be staggered from the interply sidelaps. Endlaps must be

staggered a min. of 3' apart.

For cold adhesive application, use the mop and ﬂop method and back mop

all side and end laps. Roll all side and end laps with a seam roller upon

completion of the work. (*Or substitute appropriate SBS modiﬁed bitumen

adhesive as described on page 31).

Flashing Details: Flintlastic SBS Modiﬁed Bitumen

Flashing details are accomplished using cut pieces of Flintlastic SBS

modiﬁed bitumen (base ﬂashing and counterﬂashing strips), sometimes in

combination with appropriate prefabricated ﬂashing components.

The ﬂashing and counterﬂashing membrane are set in either hot asphalt or

appropriate SBS modiﬁed bitumen elastomeric ﬂashing cement, or torch

applied. The same side and endlap rules apply to ﬂashing details as to ﬁeld

membrane. Examples of typical ﬂashing details are as follows:

Shingle Roof Transition

Existing shingles must be removed and replaced to accommodate this

detail. At transitions from a “ﬂat” roof section to a sloped, shingle roof

section the completed Flintlastic SBS modiﬁed bitumen roof system

must extend a min. of 18" up the sloped section, past the transition point.

(Note that the base sheet must ﬁrst be installed, extending up the sloped

Shingle roof transition

section a min. of 2" past the line where the membrane counterﬂashing will

end so as not to torch or mop directly to the deck.) Next, at the transition

area, a min. 30" counterﬂashing strip of Flintlastic SBS modiﬁed bitumen

cap sheet must be fully adhered. Position the counterﬂashing strip so that

it extends 6" onto the exposed ﬁeld membrane and a min. of 24" up the

sloped section of roof (min. 6" beyond the turned up ﬁeld membrane). Over

the Flintlastic SBS modiﬁed bitumen ﬂashing plies the CertainTeed No.15

Asphalt Felt or Roofers’ Select™ shingle underlayment is mechanically

fastened, beginning 4" above the transition area. Next the shingle starter

row and ﬁrst course of shingles are installed, beginning 2" above the

transition area.

Note: In regions where snowfall occurs, install CertainTeed WinterGuard™

or Black Diamond™ Base sheet to the sloped section prior to installation of

the asphalt shingles, overlapping the base ﬂashing a minimum of 4" and set

in FlintBond Trowel grade.

Parapet Wall

Noncombustible cant strip must be installed at the base of the parapet wall

for SBS torch-applied systems. Appropriate CertainTeed base sheet and all

ﬁeld membrane plies must extend a min. of 2" beyond the top of the cant

strip. For nailable walls, also install base sheet from the top of the cant strip

to the outside edge of the parapet wall. Parapet wall ﬂashing membrane

(Flintlastic SBS modiﬁed bitumen) not exceeding roll width must extend

to the outside edge of the parapet wall if coping is used, or a min. of 8"

above the top of the cant strip if termination bar and/or counterﬂashing are

installed, and 4" onto the ﬁeld membrane.

Drains – SBS

The CertainTeed base sheet should extend into the drain, set in hot asphalt

or SBS modiﬁed bitumen ﬂashing adhesive in a 9" area around the ring and

Drain detail, hot asphalt applications – part A

ﬂange. A strip of Flintlastic SBS modiﬁed bitumen membrane large

enough to extend a min. of 4" from the lead ﬂashing edge (min. 40"x 40") in

all directions is applied over the base sheet, with the drain hole cut out.

Drain detail, hot asphalt applications – part B

A min. 30"x 30" lead ﬂashing set in compatible ﬂashing compound

is secured next. Over this, the ﬁeld roof membrane is applied in

normal fashion.

Drain detail, hot asphalt applications – part C

The drain opening should be cut out while the membrane is still warm and

the edges sealed (allow the Flintlastic SBS modiﬁed bitumen membrane

to extend into the drain, well adhered). Lead ﬂashing is peened ﬂat against

drain bowl sides. Set the drain cap in place and secure the clamping ring

while the membrane is still warm.

Drain detail, hot asphalt applications – part D

Example of raised curb detail

Vent Pipes

After installing the base sheet, position a piece of smooth Flintlastic

membrane and mark the dimensions of the vents. Cut a hole corresponding

Vent pipe detail, hot asphalt applications

to the pipe size so that a snug ﬁt is achieved. The membrane piece must

be large enough to extend a minimum of 4" beyond the outside edge of the

vent ﬂange in all directions. Secure the membrane strip using hot asphalt

or SBS modiﬁed bitumen ﬂashing adhesive and press into place. Install the

vent pipe collar, properly fastened. Install the Flintlastic SBS membrane.

Use modiﬁed bitumen ﬂashing adhesive to seal the base of the vent pipe

where the ﬁeld membrane ends.

Basic Application: Flintlastic SA Modiﬁed Bitumen

Important Application Considerations

• Do not attempt application if ice, snow, moisture or dew are present.

Bonding substrates must be clean, dry and free of dust or other inhibitors

of proper adhesion. Ambient temperature must be 50ºF or above.

• Store Flintlastic SA rolls indoors on pallets, protected from the elements.

Rolls that are improperly stored or have been warehoused for prolonged

periods of time may lose their tack.

• Do not apply membrane that has been improperly stored, exposed to

moisture, or has lost its tack. If the material isn’t bonding, STOP the

application!

• Always remember to put safety rst and follow all OSHA safety guidelines

with any rooﬁng installation.

• Substrates must be free of dust, dirt, oil, debris and moisture.

• Primer, if used, must be applied at the specied rate and must be allowed

to thoroughly dry.

• Work with manageable lengths of MidPly and Cap for the particular job.

Where appropriate, cut rolls into 1/3- or 1/2-roll lengths and allow material

to relax prior to installation.

• In cooler weather, a hand-held hot air welding gun can be used to

warm the sidelap areas and improve adhesion (prior to application of the

FlintBond SBS Modiﬁed Bitumen Adhesive).

• Use caution with the weighted roller at endlap areas. Don’t squeeze out

too much adhesive.

• When applying MidPly (or PlyBase) directly to substrate, design adequate

roof ventilation into the system through the use of roof relief vents.

• Do not mix Flintlastic SA membranes with other types of roof membranes.

Flintlastic SA membranes are speciﬁcally designed to be applied together.

The permanent top ﬁlm of the MidPly, PlyBase and NailBase cannot

receive torching, hot asphalt or other non selfadhering application

methods. The Flintlastic SA Cap (or SA Cap FR), PlyBase and MidPly

cannot be applied to any surfaces other than as described herein.

• Do not use cold adhesives with Flintlastic SA membranes other than for

ﬂashing details and cap sheet overlaps as described herein.

• Refer to the CertainTeed Commercial Roof Systems Manual for complete

requirements.

• All plies of the assembly should be installed in one day. If blue lm

must be exposed for longer periods of time, cover with tarp or suitable

alternate protection.

• When applying Flintlastic SA on slopes exceeding 1" in 12", membranes

shall be back nailed. When applied parallel to the slope, Flintlastic SA

shall be blind-nailed at end laps 2" in from top edge, 6" o.c. through tin

discs and to wood nailers. See General Requirements Section of the

CertainTeed Commercial Roof Systems Manual for details.

Deck Preparation

CertainTeed recommends the use of Flintlastic SA NailBase base sheet in

conjunction with all self-adhering membrane roof installations. Flintlastic SA

NailBase can be mechanically attached to nailable substrates or applied

using hot asphalt (non-nailable substrates). For non-nailable substrates

where use of hot asphalt to adhere the base sheet may not be appropriate,

Flintlastic SA MidPly or Flintlastic SA PlyBase may be used in lieu of

Flintlastic SA NailBase on surfaces properly primed with FlintPrime

™

SA.

However, note that without the use of a base sheet, the membrane may

be difﬁcult to later remove (if necessary) and certain UL and FM listings for

the products may not apply. Prior to application of Flintlastic SA products,

ensure roofs have positive drainage. Consult the local building ofﬁcial for

minimum slope and drainage requirements.

Application of Flintlastic SA NailBase

Beginning at the low point of the roof, mechanically fasten Flintlastic SA

NailBase to nailable deck using appropriate fasteners. Start with an

appropriate roll width (1/3 or 1/2 roll)

to accommodate offsetting of

sidelaps of subsequent layers of

MidPly and/or Cap sheet. Install

so that no sidelaps are against the

ﬂow of water. A minimum fastening

pattern is every 9" on center on

sidelaps and every 18" on center

in two staggered rows in the ﬁeld

of the sheet.

Prime non-nailable substrates such

as concrete using FlintPrime SA

polymer-based primer. Allow to

dry thoroughly, but not more than

4 hours to retain tack-enhancing

properties. Apply SA NailBase using

ASTM Type III or IV hot asphalt* at

the rate of 25 lbs. per 100ft

(Spot

mopping – 15 lbs. per 100ft

) or

self-adhere SA PlyBase (or MidPly).

Overlap base sheet sidelaps 2" and endlaps 4". Offset endlaps a minimum

of 3'. Turn base sheet over fascia. Do not leave installed base exposed.

Cover in the same day with Flintlastic SA MidPly and/or Flintlastic SA Cap

(or SA Cap FR).

Don’t leave the installed Flintlastic SA NailBase exposed to the weather;

cover with Flintlastic SA Cap the same day.

Application of Flintlastic SA Mid Ply or PlyBase to insulate decks

SA MidPly or PlyBase may be adhered directly to mechanically fastened

FlintBoard ISO or adhered to FlintBoard ISO Cold.

Before installing, sweep the surface of the insulation boards to remove any

dust, dirt or sand particles that could interfere with adhesion.

Start application at the low point of the roof. Install ﬂush to roof edge.

Design layout so that no sidelaps are against the ﬂow of water.

Application of Interply

Note: Proceed to “Before Installing Flintlastic SA Cap (or SA Cap FR)”

if installing a 2-ply system.

Before installing Flintlastic SA MidPly (or PlyBase), sweep the underlying

base sheet or primed surface to remove any dust, dirt or sand particles that

could interfere with adhesion.

Apply MidPly (or PlyBase) over installed Flintlastic SA NailBase or, for

non-nailable decks such as concrete, properly primed substrates. Surface

must be dry and free from dust or dirt.

Start MidPly (or PlyBase) application at the low point of the roof with

appropriate roll width to offset sidelaps 18" from sidelaps of base sheet.

Install ﬂush to roof edge if over base sheet, otherwise turn the MidPly (or

PlyBase) over the fascia minimum 2" and secure. Design layout so that no

sidelaps are against the ﬂow of water.

Cut rolls into manageable lengths.

Fold the membrane back halfway

lengthwise to remove the split

release ﬁlm. Press membrane

securely into place, and repeat with

the opposite half of the membrane.

Use a heavy, weighted roller over

the entire surface of the Flintlastic

SA MidPly (or PlyBase) membrane

to secure the membrane. Work

outwards to eliminate voids.

Overlap sidelaps of subsequent MidPly (or PlyBase) membrane lengths

2" and endlaps 6". Offset (stagger) endlaps minimum 3'. Cut endlaps at

opposing diagonal corners at an angle approximately 5-1/2" long by the

selvage dimension from the corners to minimize “T”-seams. Apply a bead

or small trowel dab (quarter size) of FlintBond

™

SBS Modiﬁed Bitumen

Adhesive, trowel or caulk grade, at the edge of the angled cut to avoid a

capillary. Use of a hand-held hot air gun at the joint area prior to rolling the

membrane will maximize adhesion. In areas prone to cold temperatures,

snow and freeze-thaw cycles, it may be more effective to use the hot air

gun to form joints, and to completely ﬁll all mole holes with asphalt that

has been slightly melted using the gun. It is recommended to apply a bead

of FlintBond SBS Modiﬁed Bitumen Adhesive, caulk grade, at all MidPly

(or PlyBase) side and endlaps to eliminate a capillary.

Don’t leave the installed Flintlastic SA MidPly (or PlyBase) exposed to the

weather; cover with Flintlastic SA Cap the same day.

Before Installing Flintlastic SA Cap (or SA Cap FR)

If roof edge detail utilizes edge metal, proceed as follows. If MidPly has

been applied, install minimum 26 gauge edge metal using appropriate

fasteners, and set entirely in a uniform 1/8"-1/4" thick troweling of

FlintBond SBS Modiﬁed Bitumen Adhesive, trowel grade. Remove any

oil from the metal surface using a vinegar and water solution. Prime the

horizontal surface of the metal with FlintPrime SA and allow primer to dry.

Apply a bead of caulk grade FlintBond adhesive to the edge of the metal

where it meets the MidPly. Proceed with Flintlastic SA Cap (or SA Cap FR)

installation.

If MidPly is not speciﬁed: Over the Flintlastic SA NailBase, install a 9"

wide strip of MidPly onto the ﬁeld of the roof and ﬂush to the roof edge,

self-adhered. Install minimum 26 gauge edge metal using appropriate

fasteners, set entirely in a uniform 1/8"-1/4" thick troweling of FlintBond SBS

Modiﬁed Bitumen Adhesive, trowel grade. Remove any oil from the metal

surface using a vinegar and water solution. Prime the horizontal surface of

the metal with FlintPrime or FlintPrime SA and allow primer to dry. Apply a

bead of caulk grade FlintBond SBS Modiﬁed Bitumen Adhesive at the roof

side edge of the metal where it meets the MidPly strip. Proceed with cap

sheet installation.

Similarly, complete your sheet metal ﬂashing installation using cut MidPly

ﬂashing collars at all ﬂashing details prior to ﬂashing application. Seal

edges of MidPly ﬂashing collars with a bead of FlintBond. See “Typical

Construction Details,” starting on page 45 for examples. If MidPly has been

installed as part of the system, set ﬂanges in trowel grade FlintBond and

properly fasten. All cap sheet ﬂashings installed to transitions that overlap

onto mineral surface must be set in a uniform troweling of FlintBond trowel

grade adhesive.

Application of Flintlastic SA Cap (or SA Cap FR)

Before installing Flintlastic SA Cap (or SA Cap FR), sweep the surface of the

installed SA NailBase (or PlyBase) or MidPly clean. To install Flintlastic SA

Cap (or SA Cap FR), start at the low

point of the roof with an appropriate

roll width to offset sidelaps from the

underlying membrane a minimum

of 18". Work with manageable

lengths for proper handling.

Position SA Cap (or SA Cap FR)

with selvage edge release strip

at high side of roof. Install in

weather-lapped fashion, with no

laps against the ﬂow of water.

Once positioned, lift and fold back (lengthwise) the lower half of the

membrane. Remove the split release ﬁlm and press ﬁrmly into place.

Then repeat with the other

(high side of the roof) half of the

membrane.

Follow the same layout and split

release ﬁlm procedures as for

MidPly (or PlyBase), but overlap

sidelaps 3" and endlaps 6". Use

a weighted roller over the entire

surface of Flintlastic SA Cap (or SA

Cap FR) to secure it in place and

prevent voids, working outward

from the center of the sheet.

As subsequent membrane lengths

are installed, remove the selvage

edge release strip just prior to

overlapping to keep the adhesive

area protected and clean. Cut

endlaps at opposing diagonal

corners at an angle approx. 3" by

5-1/2" from the corners to minimize T-seams.

Use FlintBond SBS Modiﬁed Bitumen Adhesive, trowel grade, on the

entire 6" width of each endlap prior to overlapping. Apply a uniform

1/8"-1/4" troweling of the FlintBond on the entire width of the endlaps to the

underlying membrane. Install the overlapping sheet. Always apply FlintBond

(extend beyond underlying lap minimum 1/4") on the entire width of any

overlap when applying SA Cap (or SA Cap FR) over another mineral surface

such as the SA Cap (or SA Cap FR) endlap.

At all vertical and other ﬂashing points, apply FlintBond SBS Modiﬁed

Bitumen Adhesive, trowel grade,

wherever there is an overlap onto

mineral surfacing.

Once the membrane has had a

chance to bond, check all laps

and joints for full adhesion. If the

membrane can be lifted at any

area it is not properly adhered.

A seam probing tool can be helpful

to check for small voids at laps.

If necessary, use appropriate hand-held hot air welding tool and seam roller

or an application of FlintBond to seal small unbonded areas if they exist.

Included in this manual are a few common construction details. Please refer

to CertainTeed’s standard details or the NRCA for details not found within

this manual. Important to note with all details, all metal must be primed

and set in FlintBond Trowel Grade adhesive and all overlaps over mineral

surfacing must utilize FlintBond Trowel Grade adhesive.

The Proper T-Seam Detail

• Before adhering Flintlastic SA MidPly or Cap (or SA Cap FR) endlaps,

trim the underlying sheet’s lower corner at the end of the roll.

• Follow with the overlapping sheet, trimming the upper outside corner.

• Corners should be trimmed on a diagonal angle 5½" long from end of roll

to outside edge.

• Width of trim should be

equal in width to the

sidelap specified

(3" for Flintlastic SA Cap

[or SA Cap FR] and 2"

for Flintlastic SA MidPly

[or PlyBase]).

• Trimmed corners

should be completely

covered by application

of succeeding courses.

• Note: If using Flintlastic

SA MidPly (or PlyBase),

apply quarter-size dab

of FlintBond at T-seam area. If using Flintlastic SA Cap (or SA Cap FR),

the endlap should be completely set in trowel grade FlintBond along the

entire 6" lap width.

Rake Edge Detail

• Cut selvage area at an angle

at all rake edges.

• Apply a bead of FlintBond caulk

along cut edge to eliminate

mole holes.

Job Completion

Before considering any roof project complete, walk the roof and check laps

for any signs of unbonded areas (a trowel can be used for this purpose).

Check ﬂashing details to be sure they are secure. Leave roof and premises

clean and free of any rooﬁng debris (daily). Be sure all vent caps are snug

and drain screens securely in place.

Safety Tips

As stated in the warning on page 18, use of propane torches and hot as-

phalt requires thorough knowledge and skill in all aspects of safety with re-

spect to their use and handling. CertainTeed recommends that professional

applicators receive the CERTA torch safety training as offered by the MRCA

or NRCA (see inside cover) and participate in all asphalt heating and

handling safety training available through their local rooﬁng associations,

ARMA and NFPA (see inside cover), local ﬁre departments, OSHA and the

NRCA, among others.

Under no circumstances should Flintlastic modiﬁed bitumen

rooﬁng application be attempted by “do-it-yourselfers” or any

persons other than professional, trained roofers. It is the rooﬁng

contractor’s sole responsibility to be certain all crew members are

appropriately trained in safe and proper use of propane torching

and hot asphalt equipment and procedures.

The following safety tips are a general reference only and are in no

way all-inclusive.

Job Watch

When the torch application method is used, it is important to remember

that carelessness resulting in heat entering a crevice may cause concealed

smoldering. A supervisor trained in ﬁre safety should remain on the jobsite

a minimum of 4 hours after cessation of torching to check for any signs

of smoke, smoldering or ﬁre. The safety check should utilize infra-red

thermometers and should include a thorough interior check of the attic,

crawl spaces and return air ducts in addition to the roof area where torches

have been utilized. Prior to leaving the jobsite the contractor must be cer-

tain that all chance of ﬁre, including smoldering ﬁre, has been eliminated.

Personnel

• Proper clothing, including work boots, long pants, long sleeved shirts

and gloves, must be worn. It is the contractor’s responsibility to require

employees to wear proper attire.

• Workmen, other than the torch operator, should be not closer than 3 feet

to the torch ﬂame.

• It is the contractor’s responsibility to observe all re prevention policies

and practices during the installation of the roof system.

• It is the contractor’s responsibility to train, instruct and warn employees on

the use and handling of propane torching equipment.

• Extra caution must be used when torching near exposed edges of

insulation to prevent ﬂame from coming into contact with any ﬂammable

material. Contact for any length of time with lead or other materials

affected by heat must be avoided.

• Never use the equipment in an enclosed area.

• Refer to NFPA S8 “Standard for the Storage and Handling of Liquied

Petroleum Gas” and appropriate publications of the National Propane Gas

Association (1150 17th St. NW, Ste. 310, Washington, DC 20036-4623

Ph. 202-466-7200) and the National Fire Protection Association

(1 Batterymarch Park, Quincy, MA 02169-7471 Ph. 617-770-3000).

Fire Department Regulations

• Written notice should be given to the local re department and any

necessary permits must be acquired.

• The required number of re extinguishers shall be on the roof at all times.

• Portable smoke detectors should be installed in attics as required by the

local ﬁre department.

• All supervisors and crew members on the jobsite shall have re safety

training. The crew supervisor or foreman must remain on the jobsite at

least 4 hours after cessation of torching, and shall check the complete

roof and attic area for any signs of smoke or smoldering.

• No ammable liquids shall be stored or used on the roof (excluding LPG in

approved containers). Any LPG not in use shall be stored on the ground.

Tools and Equipment

• Be certain that all torching equipment is in good working order.

• Be certain cylinder valves are clean.

• Use an adjustable pilot with a complete shut-off valve.

• Use a int or electronic ignitor to light the torch. Matches or disposable

lighters are unsafe and not acceptable.

• Do not use any equipment without an operating pressure gauge.

• Do not operate any pressure gauge beyond the top of its scale, near

excessive heat (above 150°F) or where there is excessive vibration.

• Use a torch stand to direct the torch ame upward when the torch is

brieﬂy set down. Shut off completely when not in use.

• Propane tanks must be secured in an upright position, placed a minimum

of 10' from the torch ﬂame at all times.

• Secure propane tanks when on the roof.

• Increase the size of the propane tank if necessary to prevent frost from

occurring. Never heat the tank with a torch or any other device, and never

put the torch ﬂame anywhere near the tank.

• Never turn a propane tank on its side to increase pressure.

Liquid could escape.

• Protect cylinder valves, and where possible use cylinders that have valve

protection welded to the cylinder. Never lift a cylinder by the valve.

Valves are made of soft brass and are easily broken.

• Do not tighten brass ttings too tightly with a wrench.

• Do not attempt to put out a cylinder re if it cannot be done without

tipping the tank; Call the ﬁre department.

• Never ll a propane cylinder that is in need of repair.

• Never lay a torch to rest on a gas cylinder.

• Use only hose intended for use with LP gas.

• Do not use hose longer than 50'.

• Use an adjustable, U.L. listed regulator with the torch.

• Keep vent in pressure regulator unobstructed at all times.

• Make sure ow of gas through regulator is in the proper direction.

Directional ﬂow is indicated on the regulator.

• Use a soap solution to check for gas leaks before lighting torch.

Then check for proper operation of the torch. Never check for leaks

using lighter or matches.

• If a leak occurs, stop work immediately and repair all relevant parts.

Do not use any torch equipment that is leaking gas at any ﬁtting.

• Stop torching immediately if any propane odor is detected.

• Check hoses frequently for wear and tear, and do not allow torch ame

to come into contact with them. Keep hoses free of kinks and do not

allow heavy equipment to roll over them. Also check hoses for any signs

of burned or charred areas.

• Be aware of the difference between liquid and vapor gas bottles and

dispensing equipment.

• Treat the torch as if it is always burning. In sunlight it can be difcult to

see the ﬂame, and when working near mechanical equipment you cannot

always hear the torch.

• Never leave a torch unattended.

• Never lay a torch over the edge of the roof.

• Do not use a trowel as a torch stand.

• When shutting off the torch, close the propane cylinder valve rst and let

the remaining gas burn out of the hose before closing the torch valve.

• Keep an ABC or Halon re extinguisher on the roof, readily accessible

to each worker using a torch at all times. Make sure the extinguisher is

readily accessible, but not so close to the torch or propane equipment

that it cannot be safely accessed in the event of a ﬁre.

• When using a dry chemical type extinguisher, direct the chemical stream

at the base of the ﬁre from a safe distance of about 10' to 15'. Sweep the

ﬁre away from you, starting at its nearest point and moving the chemical

stream toward the furthest point.

• Do not use soda acid re extinguisher—it spreads the ame.

• Check all equipment for wear and tear and repair or replace as

necessary.

• Use extreme caution when working with torches in areas where you

cannot see. Heat the membrane away from the area and then apply it to

the ﬂashing. Do not torch directly into any crevice or unsafe area where

ﬂame could be sucked in.

• Protect all equipment from damage; store in a toolbox.

Building Safety

• Use noncombustible type cant strips such as perlite or ber glass and

cover them with appropriate CertainTeed base sheet.

• Use appropriate CertainTeed base sheet over all nailable deck types

including plywood, wood, lightweight insulating concrete, and over all

insulations and any ﬂammable surface.

• Use noncombustible insulation, and cover it with appropriate CertainTeed

base sheet (see also page 12).

• Install metal ashings to penetrations or protect ashings with tight-tting

collar prior to torching.

• Use a small detail torch when applying ashing details.

• Be certain all air conditioning units, exhaust fans, and air intake fans in the

work area are shut off at the roof control.

• Shield air conditioning units and other protrusions with perlite or similar

panels when using the torch around them. Heat rooﬁng membrane away

from air conditioning units, fans, soil pipes, and all other protrusions, and

set in place while still hot. Use extreme caution to prevent the ﬂame from

being pulled into the building interior.

• Feather seams around details with a warm trowel.

• When torching at ashings, corners or voids in the roof or roof deck, never

torch directly. Always torch the membrane to be applied and then adhere

it to the corner or joint.

• Use caution when torching near pipes in the event there is suction

present. Failure to utilize base sheet as required by manufacturer

speciﬁcations is extremely dangerous as the base sheet provides a

protective covering for underlying combustibles.

• Examine the roof substrate for any void, hole or gap and ll it with

noncombustible or perlite cant strip. Cover the cant strip with CertainTeed

Type G2 ﬁber glass base sheet.

• Never torch directly to insulation. Appropriate CertainTeed base sheet is

required over all insulations. RIC/TIMA recommends that polyurethane and

polyisocyanurate insulations be isolated from the roof membrane via the

use of an additional layer of noncombustible insulation and CertainTeed

base sheet, or an interim base ply acceptable to the membrane

manufacturer.

• Install CertainTeed Type G2 ber glass base sheet over all ammable

surfaces and insulations. Base sheet must ﬁt tightly around all deck

openings and must turn up parapet walls so that torch ﬂame cannot ﬂash

down into and start a ﬁre underneath the deck.

• Never torch into any area where you cannot see; do not use the torch in

areas such as under air conditioning units or behind counterﬂashing.

• Don’t torch directly to wood ber cant strips or wood ber insulations.

• Don’t torch directly to any cant strip, insulation, wood or any other

ﬂammable surface.

• Never torch near gas lines or electrical wires.

• Never torch to ammable surfaces such as EPS insulations.

• Never torch around ammable vents.

• Do not point the torch under rooftop equipment.

• Do not direct the torch down open roof penetrations, or near openings

around roof penetrations.

• Never point the torch at low ashings where there is an overhang and

ﬂame could get up under the counterﬂashing (such as around skylights or

prefabricated curbs with ﬁberboard sidewall insulation).

• Torching equipment is made for roong application only and should not be

used for drying out a roof or as a preheater torch.

• Never apply modiﬁed bitumen products directly over exposed conduits or

pipes laying on the roof deck.

• LP gas is heavier than air. Do not work in an enclosed area where gas can

accumulate.

• Do not rest an operating torch directly on the membrane. There is danger

of ﬁre and danger of damaging the membrane.

• Don’t lay an operating torch on an open penetration on the roof. If the

penetration is part of an air intake system, the ﬂame could be sucked into

the building.

Additional Hot Asphalt Considerations

• Maintain kettle and tanker temperatures less than 25°F below the actual

ﬂash point of the material used.

• NEVER heat materials to or above the actual ﬂash point.

• Don’t maintain asphalt at high temperatures for prolonged periods of

time.

• Don’t allow asphalt to stand in luggers for long periods of times.

• Use insulated hot bitumen transport lines to help maintain acceptable

bitumen temperature at point of application.

• Circulate bitumen while heating.
