Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose the HT grade when metal, tile or dark-colored roof coverings will push deck temperatures above what standard underlayments tolerate. Plan laps and cut rolls before removing release liners on windy days, and carry rolls upright to avoid core damage. Spec it along eaves and valleys in northern climates for ice-dam defense, and coordinate with compatible RESISTO flashings for a continuous waterproofing detail.
Membrane surfaces can be slippery, so wear non-slip footwear and fall protection while installing underlayment on pitched roofs.
