Expert Verdict — Reviewed by the SuperArbor Pro Desk
HT-rated underlayments are specified under metal, tile, and other hot assemblies where standard asphalt felts can bleed or stick. Roll out horizontally from the eave with the laps and fastening pattern per the printed instructions and local code, and keep rolls dry until installation. Order rolls based on roof area plus lap allowance.
Underlayment membranes can be slippery when wet or dusty; wear appropriate footwear and fall protection on sloped decks.
