Built to Control Water. Manufactured to Perform.
Sentry combines advanced coating, lamination, extrusion, printing, and rewinding capabilities to create building products engineered for real-world exposure. From synthetic roofing underlayments to WRBs, our manufacturing process is focused on durability, consistency, and water-control performance contractors can trust.
Water Control Starts Beneath the Surface
The finished roof or wall is only part of the system. Beneath it, the water-control layer determines how well the structure is protected when weather, exposure, and jobsite conditions push performance to the limit. Sentry products are engineered to help contractors control water, manage moisture, and protect the structure before the final exterior layer ever goes on.
Roofnado™
Take control with Roofnado™
Roofnado™ is not just underlayment — it’s the roof’s critical water-control layer.
Engineered for North American climates, Roofnado protects the deck, reduces risk during install, and defends the structure when the weather pushes systems to their limits. Because when the roof is tested, the layer beneath matters most.
Sahara™
Weather Resistive Barriers
Sahara™ WRBs stop bulk water while allowing trapped vapor to escape. Powered by DRYZA™ Smart Nano Technology, Sahara helps protect the building envelope from wind-driven rain, jobsite exposure, and long-term moisture risk.
Sahara™ WRBs continue to protect long after installation—defending against water penetration while allowing internal moisture to escape.
With extended UV protection and rugged construction, Sahara™ WRBs are made for the real-world conditions contractors face—offering peace of mind from the moment it’s installed to the lifetime of the building.
Sahara™
