Why We Use GAF Systems

GAF is one of the world’s leading roofing and waterproofing manufacturers, known for high performance membrane systems used across residential and commercial construction projects.

Their waterproofing systems are designed for durability, UV resistance and long-term performance under demanding environmental conditions.

At Your Subbie, we install selected GAF systems for flat roofs, decks and waterproofing applications where reliability and clean detailing are essential.

GAF TPO Waterproofing Systems

GAF TPO membranes are advanced single-ply waterproofing systems designed for flat and low-slope roofing applications.

The system uses hot-air welded seams to create strong waterproof joins while maintaining flexibility and durability over time.
