Why Roof-Master Is the Go-To for Wet-Surface Repairs
Roof-Master products are purpose-built for challenging, moisture-laden repair scenarios on asphalt shingles, built-up roofs (BUR), flashings, metal and masonry. Both Roof-Master 220 and 221 are ASTM-compliant (ASTM 4586 Type I and ASTM D-3409), low-VOC (<300 g/L) and formulated to remain workable in all weather while curing to a durable, water-resistant, elastic seal.
Roof-Master 220: A high-quality, all-weather flashing cement with excellent underwater adhesion, ideal for patching emergency holes, cracks and sealing leaks around chimneys, vents, skylights, gutters and metal joints on wet or dry surfaces.
Roof-Master Plus 221: An advanced SBS rubberized formulation that starts soft and pliable for easy application into intricate details, then gradually hardens to an elastic, long-lasting, water-resistant compound — perfect for ultimate emergency repairs in the toughest conditions.
