Expert Verdict — Reviewed by the SuperArbor Pro Desk
WIP 300HT is the high-temperature choice when dark metal, tile, or other heat-collecting coverings would degrade standard adhesive underlayments. Prime and clean the deck per Carlisle's instructions, roll the membrane firmly to bond, and maintain required laps. Its nail-sealing quality makes it well suited for ice-dam-prone eaves and valleys.
Self-adhering membranes are slippery, especially with dust or moisture; wear appropriate footwear and use fall protection during installation.
Order Carlisle WIP 300HT high-temp self-adhering underlayment for heat-rated protection under metal and tile roofs.
