Products / Hybrid Silicone Roof Patch

Hybrid Silicone Roof Patch is a heavy-bodied white silicone repair compound that Topps sells for sealing leaks, cracks, seams, blisters and roof joints, applied by trowel or brush. The product pages say it is compatible with TPO, EPDM, built-up and spray foam roofs, is tack-free in 3 to 6 hours with a full cure in 24 hours, and is not recommended over asphalt shingles. The maker's catalog lists it for previously coated roofs, metal, built-up, mineral cap sheets, APP and SBS membranes, weathered EPDM and TPO, spray foam and rainwater containment systems. It is sold in pails and in 10.3 oz tubes, and Topps posts no technical data sheet for it.
