Expert Verdict — Reviewed by the SuperArbor Pro Desk
Thirty-pound felt is the traditional choice when a spec or code calls out No. 30 ASTM D226 underlayment, and it provides a heavier, more tear-resistant layer than 15# felt. Roll it flat and fasten per the shingle manufacturer's lap and fastening schedule, keeping the surface dry until covering. Store rolls upright and dry; wet or crushed felt will not install flat.
Felt underlayment is slippery, especially when wet or dusty; wear appropriate footwear and use roof anchors and fall protection on slopes.
