Questions & Answers

Do i need to use a base layer for this?
ByDec 19, 2025
1 Answer | 
Answer This Question

Yes, the installation of the Tri-Ply APP Granular Cap Sheet typically requires a base layer for proper application. A base layer, such as the Tri-Ply #75 Base Sheet, is recommended as it provides additional strength, nail-holding ability, and resilience to prevent splitting and cracking of the membrane. This ensures a durable and effective roofing system. For detailed installation requirements and guidelines, you can refer to the following resources: Tri-Ply APP Granule Membrane Tri-Ply #75 Base Sheet These links provide comprehensive product documentation and specifications.

    how do I apply to wood
    ByMay 17, 2018
    1 Answer | 
    Answer This Question

    It is not recommended to use the Tri-Ply Torch APP Granule directly to a wood deck since it is installed by using a torch. Depending on your specific conditions, you may want to consider using the Liberty Self-Adhered products that do not require a torch or adhesives to install. To go over recommended solutions for your specific roof conditions, please contact GAF product and technical team at 877-GAF-ROOF (877-423-7663), Option 5.
