Island roofs live in salt with no inland relief, and everything you need to fix one comes over on a boat. Interlock is the roof you install once: period-correct profiles for Edgartown and Oak Bluffs, aluminum that will not rust, and a lifetime limited warranty that transfers with the house.

Everything arrives by ferry — materials, crews, repairs. If the house is seasonal, the real value is never opening it in spring to discover what the winter did. One permanent roof removes that whole category of worry.
Edgartown's white captains' houses and the Oak Bluffs Campground cottages are among the most recognisable historic streetscapes in New England, both under district review. Interlock's cedar-shake and slate profiles carry those rooflines in a material that will not split, curl or streak.
Steel panels and steel fasteners corrode out here — fasteners first, which loosens a system before it looks worn. Interlock is aluminum throughout, and up-island wind at Chilmark and Aquinnah has nothing to lift.

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.
