Expert Verdict — Reviewed by the SuperArbor Pro Desk
Dry-in the deck with horizontal courses starting at the eave, lapping upper courses over lower per TAMKO and local code, using the printed laying lines to hold alignment. This 30# Type I felt suits asphalt, tile and wood shake applications; step up to a synthetic underlayment or self-adhered membrane where higher tear resistance or ice-dam protection is required.
Felt becomes slippery, especially when wet or dusty; wear slip-resistant footwear and use fall protection while unrolling on the deck.
Order the TAMKO No. 30 ASTM D-4869 Type I felt roll for dependable pre-shingle deck protection.
