TRI-BUILT 36" x 66.7' Ice & Water Underlayment

TRI-BUILT® Ice & Water Roof Underlayment is an all-purpose roof underlayment and leak barrier. TRI-BUILT® Ice & Water underlayment is ideal for use under shingle, slate, wood shake and other steep slope roofing materials. TRI-BUILT® Ice & Water underlayment provides a rubberized and flexible waterproofing membrane that helps keep your home or building dry. This product can be used over an entire roof deck or for sealing critical areas on your roof such as perimeter edges, valleys, details and penetrations. For severe or harsh climates (ice, snow, strong winds or heavy rain), full roof coverage is recommended.
