Expert Verdict — Reviewed by the SuperArbor Pro Desk
High temperature underlayment is the right choice beneath tile, metal and dark low-ventilated assemblies where standard self-adhered membranes can soften. Plan laps per GCP's published instructions and stage rolls out of direct sun. For cold-climate eaves, verify the temperature window before applying to the deck.
Use fall protection and roof jacks when handling rolls on sloped decks, and apply only when the deck and weather are within the manufacturer's temperature limits.
