Expert Verdict — Reviewed by the SuperArbor Pro Desk
A 30# ASTM D226 Type II felt is the standard heavy-duty choice under tile and metal where a more robust underlayment than #15 is specified. Roll it out flat, keep laps to the code-required minimum, and store rolls dry and off the ground. On steep tile slopes follow the fastening and lap schedule for the tile system.
Felt underlayment can be slippery, especially when damp; wear appropriate footwear and fall protection on the roof.
