Expert Verdict — Reviewed by the SuperArbor Pro Desk
Use this at eaves for ice-dam courses, in valleys under W-metal, and around skylights and pipe penetrations where full self-adhered protection matters. Prime questionable decks only if the manufacturer's instructions call for it, and apply shingles within the membrane's exposure window. For a full self-adhered deck in high-wind zones, its Class A listing and Miami-Dade NOA make it a strong candidate.
Sand surface rolls are heavy (60 lb); use proper lifting technique or mechanical help, and work from stable footing with fall protection on pitched roofs.
Protect the roof deck with TRI-BUILT sand surface self-adhering underlayment, 195 sq ft per roll.
