Protecting vulnerable roof areas from water infiltration is critical to preventing interior damage and maintaining structural integrity. WIP 100 Granular-Surface Self-Adhering Roofing Underlayment, manufactured by Henry, a Carlisle Company, offers roofing contractors an advanced, code-approved waterproofing solution built to withstand extreme weather conditions.
This 55-mil flexible membrane features a high-performance rubberized asphalt core reinforced with strong fiberglass. It is specifically engineered to protect critical areas of the roof structure—such as eaves, ridges, valleys, dormers, and skylights—where water entry is most common. When installed, its self-sealing properties allow the membrane to close tightly around roofing nails, staples, and screws, ensuring the absolute watertightness of the primary roofing system. For total peace of mind, it can also be utilized as a full-roof covering to block all moisture and water entry.
Designed with contractor efficiency and safety in mind, WIP 100 features a split-release film that allows for faster, easier peeling and positioning on the deck. The top layer is embedded with a unique granular, skid-resistant surface that provides reliable traction for installers walking the roof. Highly durable, this underlayment resists cracking, drying, and rotting over time, which provides a exceptionally low lifecycle cost for the property owner. Whether you are working on residential or commercial sloped roofs, WIP 100 from A1A Wholesale Supply delivers the heavy-duty weatherproofing performance that professional contractors rely on.
