Metal Roofing in Hampshire County — The Last Roof Your Home Will Need
Pioneer Valley homes are worth roofing properly — and worth roofing once. Interlock's slate and cedar-shake profiles keep a Northampton Victorian or an Amherst colonial looking exactly as it should, in a material that will not split, curl or streak, backed by a lifetime transferable warranty from Interlock Roofing Ltd.

THE CHARACTER STAYS, THE MAINTENANCE GOES
Northampton, Amherst and Easthampton hold unusually intact Victorian and colonial housing, much of it originally slate or wood shake, and several towns run local historic district review. Interlock's matching profiles satisfy that expectation permanently — without the splitting, cupping and moss that real wood suffers under the valley's heavy canopy.
YOUR OLD FRAMING GETS A BREAK
True slate is heavy. Aluminum weighs a fraction of it, which matters a great deal on framing well over a century old — no reinforcement, no structural surprises.
AND VALLEY WINTERS STOP COSTING YOU
The Connecticut River valley cycles between melt and refreeze rather than staying frozen — the pattern that drives ice dams and loosens asphalt seams. Four-way interlocking panels give that water nowhere to enter.

Technician went above and beyond. He had to resecure my gutter before fixing my damaged shingles. The repair looks like they had never been damaged. Super nice gentlemen. So glad I purchased my roof through Interlock back in 2004!
