Expert Verdict — Reviewed by the SuperArbor Pro Desk
No. 30 organic felt is the traditional choice when a heavier, more tear-resistant underlayment is wanted versus No. 15. Install horizontally from the eave up with the printed laying lines setting your lap and exposure per the shingle manufacturer's instructions, and cover with the finished roof within the exposure window your local code allows.
Felt underlayment is slippery, especially when wet or dusty; wear appropriate roof footwear and fall protection during installation.
Order TAMKO No. 30 UL organic felt underlayment for dependable moisture protection under your shingles.
