One product, one promise
We install one thing — and that focus is the point.
The Interlock® Lifetime Roofing System: interlocked aluminum panels manufactured in North America by Interlock Roofing Ltd. We are not a general roofing company that also offers metal — we're Oregon's authorized Interlock installer, and this system is all we do.
Western Oregon is one of the hardest places in America to own an asphalt roof: eight months of rain feed the moss that pries shingles apart, coastal salt air corrodes steel, and the Columbia Gorge funnels wind that works exposed fasteners loose — while wildfire season makes a non-combustible roof the smart default. Rust-proof aluminum with a four-way mechanical interlock and a Class A fire rating available was engineered for exactly this — and every roof carries The Guardian Warranty, lifetime coverage that transfers when you sell.
