Metal Roofing in Sullivan County — One Roof, Lifetime Limited Warranty
Sullivan County runs from the Connecticut River up into the Sunapee hills, and a roof here gets both: valley damp and fog off the water, then real snow and freeze-thaw as the land climbs. Interlock answers both with one aluminum roof — installed once by a certified crew, with a lifetime limited warranty, transferable to the next owner.

VALLEY DAMP HAS NOTHING TO WORK ON
River fog and shaded northern slopes keep a roof wet for long stretches, which is how asphalt goes soft and how steel fasteners quietly give up. Interlock is aluminum throughout — it does not rust — and there is no exposed lap seam across the field of the roof for standing moisture to get into.
CLAREMONT'S MILL-ERA HOUSES KEEP THEIR LINES
The city's older neighborhoods carry steep, dormered, slate-era rooflines that are expensive to redo in anything heavy. Interlock's aluminum slate profile installs at 0.41 psf, against roughly 8 to 10 psf for natural slate.
THE HILL TOWNS GET WINTER FIRST
Goshen, Lempster, Washington and Croydon sit high enough for a longer, harder snow season than the river towns. The panels shed snow rather than holding a saturated mat against the deck, and meltwater finds no exposed seam to get under.
AND ONE COMPANY STANDS BEHIND IT
Manufactured by Interlock Roofing, installed by their exclusive certified New England installer, and covered by the transferable Guardian Lifetime Limited Material Warranty.

What New Hampshire homeowners say
★★★★★
Great work. He is the best
— Peter La M., Derry, NH

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.
