Expert Verdict — Reviewed by the SuperArbor Pro Desk
Run Grace Select at the eaves first, lapped over the drip edge per manufacturer detail, and use it in valleys and around penetrations where leaks start. Prime the substrate where the manufacturer calls for it, and roll the laps firmly for a watertight seal. In heavy snow regions, verify the local ice barrier code line, which often requires the membrane to extend a set distance above the eave overhang.
Self-adhered membranes are very slippery, especially on warm or wet surfaces; wear proper footwear, use fall protection, and plan footing before peeling the release liner.
