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 since 1998. We are not a general roofing company that also offers metal — we're the official, exclusive Interlock installer for all six New England states.
New England is the hardest place in America to own a roof: coastal salt air, 100-inch winters, ice dams, and freeze-thaw cycles that destroy asphalt in 15 years. Rust-proof aluminum with a four-way mechanical interlock was engineered for exactly this — which is why our early-2000s installs still look new, and why every roof carries The Guardian Warranty — lifetime coverage that transfers when you sell.
