Expert Verdict — Reviewed by the SuperArbor Pro Desk
#30 organic felt is still the workhorse underlayment for standard-slope shingle roofs; the ASTM D4869 version is the one to specify when code or manufacturer requirements call for a dry, tear-resistant rated felt. Order one roll per 2 squares and add 5-10% for laps and waste on hips and valleys. In hot weather, keep rolls shaded so the asphalt saturation does not transfer in the pack.
Felt underlayment is slippery, especially when wet or dusty; wear slip-resistant footwear and use fall protection when installing on slopes.
