Product FLINTLASTIC modified bitumen roofing systems shall be applied in accordance with installation
Application procedures contained in the CertainTeed Commercial Roof Systems Manual. The following
information is intended for general information purposes only and is not all-inclusive.
Preparation:Substrates to receive a roof system shall be firmly attached, smooth, dry, clean and
free of sharp projections and depressions. Substrates requiring priming shall be primed with
asphalt primer such as CertainTeed's FlintPrime-and be allowed to completely dry. Substrates
shall provide positive drainage. Roof shall be tapered to drains.
Installation: Install one ply of GLASBASE or other CertainTeed approved alternate base sheet
lapping 2" on sides and 4" on ends. Base sheet shall be mechanically fastened to nailable
substrates, and either solid or spot mopped in hot asphalt to non-nailable or insulated substrates
as specified in the CertainTeed Commercial Roof Systems Manual. Apply base sheet in such a
manner to provide and maintain a minimum 6" offset between side and end laps of base ply and
FLINTLASTIC finishing membrane. Over the base ply, install one ply of FLINTLASTIC GTA lapping
3" on sides and 6" on ends with end laps diagonally staggered not less than 3 feet apart. Side and
end laps should be inspected to ensure a minimum 3/8" flow of modified compound has been
achieved.
Precautions:Cold weather applications require special handling to prevent damage to the rolls and
to ensure satisfactory installation. Do not apply roofing systems over improperly prepared substrates
or substrates which contain moisture. Follow all safety recommendations relating to the use and
maintenance of liquid propane gas torches and equipment. Refer to the CertainTeed Commercial
Roof Systems Manual for additional safety information.
Maintenance:FLINTLASTIC Roof Systems do not require any additional maintenance beyond
normal yearly roof maintenance procedures. CertainTeed recommends regular roof maintenance and
inspection to determine the condition of drains, flashings and other similar items, and to prolong
the life expectancy of the roof system.
Warranties CertainTeed offers a number of different types of Roof Membrane Warranties designed to meet
the building owner's specific requirements. Please contact your nearest CertainTeed office for
additional information and requirements.
