Expert Verdict Reviewed by the SuperArbor Pro Desk

For most steep-slope jobs, UDL25-type synthetic underlayment speeds dry-in and resists tearing around fasteners compared with felt. Order based on roof squares plus a waste factor for laps and valleys. On exposed-duration or ice-and-water critical details, coordinate with the appropriate self-adhering membranes where code or detail requires.

Synthetic underlayment can be slippery, especially when wet or dusty; wear appropriate footwear and fall protection on the roof.

Order Owens Corning Titanium UDL25 synthetic underlayment by the 10-square roll for your next dry-in.
