Gilsum, NH — Charcoal Grey Interlock Shingle (21+ yrs)

The proof behind “never re-roof again”

This Gilsum, New Hampshire roof was installed in September 2004 — 55 squares of Charcoal Grey Interlock aluminum shingle. Photographed recently, it shows zero degradation: no rust, no curling, no fading beyond spec, and no replacement.

Why it matters

An asphalt roof installed the same year would now be on its second replacement. Through two decades of New Hampshire winters — heavy snow loads, ice-dam freeze-thaw cycles, and summer UV — the four-way interlocked aluminum panels have simply kept working.

This is the documented longevity evidence behind the Lifetime Limited 50-Year Transferable Warranty: when we say lifetime, we can show you the roof.
