Upgrade your roofing standard with PRIMO Synthetic Silver+, distributed by A1A Wholesale Supply. This advanced synthetic underlayment is the “Green Building” solution for modern contractors who demand speed, safety, and reliability. While traditional felt is prone to tearing, rotting, and absorbing moisture, PRIMO is 100% inorganic and water-repellent, ensuring your roof deck stays dry and protected throughout the installation process.

The “Cool Grey” top layer is specifically designed to reduce heat absorption, creating a more comfortable working surface for crews in high-temperature environments. Safety is further enhanced by an anti-slip bottom coating that grips the roof deck, significantly reducing the risk of slips and falls. With 1,000 square feet of coverage per roll—nearly 2.5 times that of standard felt—you’ll enjoy fewer laps, faster dry-ins, and significantly lower labor costs.
