Expert Verdict — Reviewed by the SuperArbor Pro Desk
Keep a pail on hand for storm-season emergency response: pour the compound over the leak area and let the water activate the gel. Because the seal is temporary, schedule a permanent repair and inspect the affected area for moisture damage once the roof is dry. It is designed for flat built-up roof membranes, not steep-slope shingle roofs.
Exercise extreme caution applying any product on a wet roof; never work on a roof during active lightning or high winds, and use fall protection at all times.
Keep DeWitt 911 Emergency Roof Patch on hand to stop flat roof leaks fast, even in a storm.
