Merrimack, NH — Deep Charcoal Interlock Slate

Deep Charcoal slate, documented in Merrimack

In Merrimack, 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 24 squares of Deep Charcoal Interlock aluminum slate — job NHNE22009, installed 2022, photographed on completion and pinned on the live project map.

The in-service record

Installed in 2022, this roof is at the start of a documented service life we track publicly — the same way we still track installs from 1998.
