Single-Layer Roofing Underlayment

Boral Acrilay roofing underlayment combines SBS-modified asphalt with an acrylic adhesive for a single-layer system that Boral says offers better adhesion than options using asphalt-based adhesives. The underlayment provides protection from weather, does not require special installation equipment, and is compatible for use with clay, concrete, stone-coated steel, composite roofing, and asphalt shingles, including on steep-slope applications. Boral says the underlayment will not rapidly degrade or crack over time. It’s offered in 39-3/8-inch-by-61-foot rolls. Pricing varies. boralamerica.com
