RoofingFoil™ is a Miami-Dade County approved all-in-one roofing underlayment and radiant barrier. 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 occuring 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 foils only barriers in both perforated and solid versions.

All products ship FREE within the contiguous (48 states) USA.
