Expert Verdict — Reviewed by the SuperArbor Pro Desk
A 10-square roll covers a typical residential roof with fewer seams than lower-coverage products, speeding installation on larger decks. Synthetic underlayment is lighter and more tear-resistant in foot traffic than traditional felts, but keep laps per the manufacturer's layout. Pair with Malarkey starter and shingles for a matched system.
Synthetic underlayment surfaces can be slippery, especially on slopes or when wet; wear appropriate footwear and fall protection.
