RoofingFoil™ + Underlayment All-in-One

RoofingFoil™ is a Miami-Dade County approved all-in-one roofing underlayment and radiant barrier.

RoofingFoil™ + Underlayment is a 16 mil, 5-layer reinforced underlayment with a white non-woven slip-resistant base adhered to a heavy duty PE woven fabric laminated to a pure aluminum foil.

Our underlayment goes great under metal, tile, slate, standing seam, and other metal and tile roofing systems that have a batten system, or a naturally occurring air space between the roofing material and the deck. Roofs with RoofingFoil™ + Underlayment are 20°F to 40°F cooler than roofs without it! For other roofing applications, check out our single-sided solid foil-only version (best used with a waterproofing underlayment).
