Coverage & How Much You Need

One 10 ft x 100 ft roll covers 1,000 sq ft before seam laps, perimeter waste, penetrations, curbs, and field cuts. For a 10,000 sq ft low-slope field, start with about 10 rolls plus project waste and detailing material.

• Field rolls = measured roof field sq ft ÷ 1,000.
• Add laps, perimeter, penetrations, curb/detail flashing, and waste from the project drawings.
• Order compatible TPO accessories separately; the membrane roll is not a complete roof system by itself.

Compatibility / Fitment

Use with a GAF EverGuard TPO system, compatible insulation/cover board, approved fasteners or adhesive, TPO accessories, and heat-welded seam procedures. Do NOT substitute this for EPDM, PVC, modified bitumen, or steep-slope shingle roofing; the system design, attachment method, and local code approval must match the project documents.

Product Expert Notes

Choose this 80 mil EverGuard roll when the project documents call for a thicker white GAF TPO membrane and the crew is set up for welded single-ply installation. It is a strong B2B listing because the buying decision is driven by exact MPN, thickness, roll size, and system compatibility rather than retail-style finish copy.
