Expert Verdict — Reviewed by the SuperArbor Pro Desk
Apply leak barrier at eaves, valleys, and around penetrations where water is most likely to collect; many codes require eave protection in cold climates. Prime or confirm deck condition before application and roll the membrane firmly to seat the adhesive. Match membrane width to valley and eave details for full coverage.
Self-adhering membranes are very slippery; wear proper footwear, keep the surface clean, and use fall protection when installing on a roof.
