Interlock Metal Roofing in Carroll County: A Lifetime System
Carroll County is snow country with a second-home problem: long, heavy mountain winters landing on houses nobody is standing in. Interlock is the roof that handles both. Aluminum, four-way interlocking, shedding snow rather than holding it — installed once and warrantied for the life of the home, with nothing to maintain in between.

THE SNOW LEAVES ON ITS OWN
From Jackson and Bartlett up through the valley, winter loads a roof and reloads it before the last one is gone. Interlock sheds snow rather than holding a saturated mat against the deck, and meltwater running under a frozen edge finds no exposed lap seam to get through. (Dam formation itself is an attic insulation and ventilation issue, which we check at every estimate.)
A HOUSE YOU VISIT SHOULD NOT NEED WATCHING
If the place is a ski house or a summer camp on Ossipee Lake, the real cost of a roof is discovering a problem in April that started in January. Interlock has no maintenance schedule and no replacement cycle — there is nothing to come back and find.
THE LODGE LOOK, WITHOUT THE WOOD
Cedar shake is the valley's vernacular, and real cedar up here splits, cups and grows moss. Interlock's cedar-shake profile holds that appearance permanently in aluminum, which does not rust.
AND IT SELLS WITH THE HOUSE
The Guardian Warranty from Interlock Roofing Ltd. is lifetime and transferable to the next owner.

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.
