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.
At Sentry, synthetic roofing underlayment is what we do — and what we stand behind.
Our Roofnado® line is built to support real-world crews, real schedules, and real jobsite conditions. From faster roll-out and secure footing to dependable performance across extreme heat, cold, and storms, Roofnado is designed to keep projects moving and roofs protected from start to finish.
Manufactured using advanced production technology and backed by deep waterproofing expertise, Roofnado® delivers consistent quality you can rely on job after job. Less downtime. Fewer headaches. More confidence on every roof.
