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.

Documented Performance After Two Decades in New Hampshire

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.
