Salem, NH — Black Interlock Slate

Black slate, documented in Salem

In Salem, 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 36 squares of Black Interlock aluminum slate — job NHNE19010, installed 2019, photographed on completion and pinned on the live project map.

The in-service record

This roof has now been through 7 New England winters — nor’easters, ice-dam seasons, freeze-thaw cycles — under its original finish and warranty. That in-service record, not a brochure claim, is why we publish it.

In the homeowner’s words

“Call me in a year and I will let you know how this roof works.”
