Portsmouth, RI — Black Interlock Slate

Black slate, documented in Portsmouth

Portsmouth sits in New England’s salt-air belt, which is exactly where aluminum earns its keep: unlike steel, it cannot rust, so coastal exposure is a non-event for the panels, trim, and fasteners alike.

A Cape’s steep, honest gable is one of the most metal-friendly rooflines in the region — see our full Cape Cod style guide for why. This install is 15 squares of Black Interlock aluminum slate — job RINE24005, 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

“We are pretty happy.”
