Sanbornville, NH — Black Interlock Slate

Black slate, documented in Sanbornville

In Sanbornville, the roof’s real adversaries are snow load, ice dams, and freeze-thaw cycling. The four-way interlocked panels leave no exposed seam for meltwater to invade, and the surface sheds snow instead of stacking it.

On a Colonial, clean coursing across simple planes is the whole look — the interlock geometry holds those lines straight for the life of the house. This install is 15 squares of Black Interlock aluminum slate — job NHNE24002, installed 2024, photographed on completion and pinned on the live project map.

The in-service record

Installed in 2024, this roof is at the start of a documented service life we track publicly — the same way we still track installs from 1998.

In the homeowner’s words

“The guys that were here doing the roofing were really great. They got it done really quickly and they were all very nice.”
