Expert Verdict — Reviewed by the SuperArbor Pro Desk
WinterGuard HT is the high-tack version of CertainTeed's winter underlayment line, chosen for hot climates and steep or re-roofing applications where standard asphalt-cold underlayments can slip or bleed. Run it full-width in valleys, at eaves for ice-dam protection and around penetrations, lapped per the printed instructions. Its ASTM D1970 listing and ESR-1492 report make it straightforward to spec where code officials require documented ice-and-water barriers.
Install on a dry, clean deck following the manufacturer's instructions and local code; use roof-walk precautions and fall protection when unrolling on sloped decks.
