Expert Verdict — Reviewed by the SuperArbor Pro Desk

Flash sills first with the 6 in. width, then jamb and head, keeping the tape shingle-lapped so water runs onto the layer below. Its ability to bond to damp surfaces and unprimed wraps makes it forgiving in real-world schedules. Use the 4 in. roll for jambs and detail work, and the 13 mil 6 in. roll for sills and higher-exposure areas.

Follow the manufacturer's application temperature and surface preparation guidance and use fall protection when flashing upper-story openings.
