HomeGuard ToughSkin 20 Roof Underlayment is an engineered, mechanically attached synthetic underlayment for sloped roofs, designed to meet the needs of today’s roofing. Toughskin’s high-strength design is 25x stronger than 15 lb. Saturated Felt and 5x lighter than 30 lb. Saturated Felt. With each roll having 10 squares of coverage (48”x250’), your installations will be faster, and more efficient - with fewer laps, cuts, and less handling when compared to felt.

A roof that lasts for decades starts with a high-quality underlayment. ToughSkin is engineered to work better for both contractors and their customers than traditional felt underlayment. The innovative Slipsafe technology makes for a safer surface to work on while lighter, wider rolls make installation faster. Four layers of protection are made to stand up to years of the harshest weather conditions.
