Most South Coast homes are on their third or fourth asphalt roof. Interlock is the one that ends the sequence — aluminum that Buzzards Bay salt cannot rust, light enough for old mill-era framing, and warrantied for as long as you own the house and beyond.

New Bedford, Fall River and Taunton hold an enormous stock of triple-decker and mill-era housing, most of it re-roofed several times over. Every cycle costs more than the last, and the decking underneath is usually near its weight limit already. One aluminum roof — a fraction of the weight of slate or tile — stops the sequence permanently.
Along Buzzards Bay — Fairhaven, Dartmouth, Westport — salt corrodes steel panels and the fasteners holding them down. Interlock is aluminum and does not rust, which is why it outlasts coated steel on a working waterfront.
The bay has historically funnelled the strongest sustained winds in southern New England; four-way interlocking panels give that wind nothing to lift.

Jose and the technician communicated easily and reviewed future work with pricing. Detailed work and assessment.

The worker did a great job removing the furnace flue that was not needed anymore

Technician went above and beyond. He had to resecure my gutter before fixing my damaged shingles. The repair looks like they had never been damaged. Super nice gentlemen. So glad I purchased my roof through Interlock back in 2004!

The warehouse manager went out of his way to accommodate my payment related requests. My installer was professional, answering all my questions and providing pictures of each step in the repair process.
