DuPont Roof Protector is an engineered synthetic roofing underlayment with a high strength to weight ratio. The four-layer construction allows for excellent grip to the deck, strength of the product to minimize tearing at the fastener points, and good gripability for slip resistance.

With 10 squares in every roll, DuPont Roof Protector allows for maximum roof coverage and efficient installation-making it easier to install than roofing felt. As a result, there are fewer overlaps, seams and fasteners, which helps reduce both labor and waste. Superior durability combined with higher thermal stability than roofing felt, enables DuPont Roof Protector to stand up to the toughest conditions.
