In regions with high solar exposure or when installing premium metal roofing systems, standard underlayments can degrade under intense heat. Starwrap HI-TEMP, distributed by A1A Wholesale Supply, is built to withstand these challenges, maintaining its integrity at temperatures up to 257 degrees F. This robust underlayment acts as a critical secondary weather barrier, protecting the roof deck from wind-driven rain and ice damming.

The product is designed with the installer in mind, featuring a split-release liner that allows for quick, precise application and an anti-slip top surface for a safer working environment. With a formulation that allows for up to 12months of UV exposure, it provides reliable protection even during extended construction timelines. Its high tear and puncture resistance ensures the membrane remains intact during the rigors of installation and throughout the lifespan of the roof.
