Expert Verdict Reviewed by the SuperArbor Pro Desk

Self-adhering MTS-type underlayments are widely used at eaves, valleys and vulnerable details, or across the full deck. Ensure the deck is clean, dry and primed where required, roll the membrane firmly to bond, and lap per the manufacturer’s directions.

Self-adhering membranes become slippery, especially when warm; wear appropriate footwear and use fall protection on the roof.
