Expert Verdict — Reviewed by the SuperArbor Pro Desk
RoofGard-Cool Grey is a good pick for hot-weather tear-off and new construction because the grey surface stays cooler than dark underlayments. Use the 1 in. lay lines to keep laps consistent and verify lap requirements for your roof pitch. Its synthetic construction resists tearing around vents and dormers better than felt, but check fastener requirements for your shingle warranty.
Synthetic underlayment can be slippery, especially on slopes or when damp; wear proper footwear and secure yourself on the roof.
