Metal Roofing in Cheshire County — Keep the Historic Roofline for Good
The Monadnock region has colonial and Federal architecture that has survived largely intact, and those rooflines were drawn for slate and cedar. Interlock keeps them exactly as they read — in aluminum, at a fraction of the weight, installed once by a certified crew and warrantied for the life of the home.

THE PERIOD ROOFLINE SURVIVES THE RE-ROOF
Walpole, Keene and the Monadnock village centers are full of houses whose proportions depend on a slate or shake roof. Interlock makes both profiles in aluminum at 0.41 psf installed — against roughly 8 to 10 psf for natural slate — so an old frame carries the look it was designed for without reinforcement.
AN OLD HOUSE STOPS BEING A ROOF SCHEDULE
Every asphalt replacement on a complex historic roof means staging, cutting and re-flashing the same dormers and valleys again. The Guardian Warranty from Interlock Roofing Ltd. is lifetime and transferable, which ends that entirely.
MONADNOCK WINTERS LOSE THEIR WAY IN
This corner of the state runs cold and swings hard between thaw and refreeze. The panels shed snow rather than holding a saturated mat against the deck, and meltwater finds no exposed seam to get under. (Dam formation itself is an attic insulation and ventilation issue, which we check at every estimate.)
AND NOTHING STREAKS OR RUSTS
Interlock is aluminum throughout, not coated steel.

What New Hampshire homeowners say
★★★★★
This has been one of our best investments ever. It wasn’t perfect when they finished but the after installation follow up has been. Navir always has been very professional, friendly and polite. I always have tried to tip him, he never accepts it but is grateful for the offer. I highly recommend this company.
