Concord, NH — Black Interlock Slate

Black slate, documented in Concord

In Concord, 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.

Single-story ranch planes read as one broad surface from the street, which rewards the evenness only fixed-exposure interlocked panels deliver. This install is 26 squares of Black Interlock aluminum slate — job NHNE14009, installed 2014, photographed on completion and pinned on the live project map.

The in-service record

This roof has now been through 12 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.
