Protecting high-sloped roof decks from the damaging effects of ice dams and water intrusion is critical for the longevity and performance of the entire roofing system. PRIMO-Guard, Ice & Water is designed as a superior self-adhesive solution for this vital function. Constructed with a robust glass mat carrier and coated with a premium blend of SBS polymers, asphalt, and additives, this membrane achieves the perfect combination of durability and flexibility, allowing it to conform to roof contours and withstand structural movement.
The underlayment features a sanded top surface, providing excellent slip resistance for safer application on steep roofs. The under surface is covered by an easily detachable silicon-based release film, protecting a highly adhesive layer of asphalt. The split-release film design simplifies installation, allowing for controlled application. Key features include excellent adhesion to multiple substrates, high flexibility, good dimensional stability, and strong resistance to tearing and puncture. It also functions as a reliable vapor barrier and is rot resistant. PRIMO-Guard, Ice & Water is highly effective when used as an underlayment on high-sloped roof decks, particularly on rakes, eaves, and valleys, areas most vulnerable to ice dam formation and water damage. Proper application requires a clean surface, potential priming, and application temperature not under 41°F, ensuring the membrane is pressed firmly to drive out trapped air and protected from site activities, sun, and bad weather until the final roofing is installed. Choose this high-performance self-adhesive ice and water underlayment from A1A Wholesale Supply for reliable protection on residential and commercial steep-slope roofing projects nationwide.
