Expert Verdict — Reviewed by the SuperArbor Pro Desk
A 30# Type II felt meeting ASTM D4869 is a dependable choice under architectural shingles where a synthetic underlayment is not specified. Keep laps per code, and roll it out flat to avoid telegraphing wrinkles through the shingles. Its slip resistance helps crews on steeper pitches, though harnesses and roof anchors are still essential.
Felt underlayment surfaces can be slippery, especially when wet or steep; use fall protection and proper footwear during installation.
