Nazar was wonderful! Gave us all kinds of suggestions to help us keep our beautiful roof long lasting for a lifetime

On Nantucket every material and every trade arrives by ferry, and the salt never stops. Interlock means you do that once. An aluminum roof that holds the island's weathered cedar-shake appearance permanently — no splitting, no cupping, no corrosion, and nothing to arrange from the mainland again.

Getting materials and crews to the island is the hidden cost of every Nantucket project. A roof installed once and never replaced removes that from your future entirely — which is a far bigger saving here than the roof price alone suggests.
Real cedar weathers unevenly here, splits and cups under constant salt and damp, and turns into a maintenance schedule. Interlock's cedar-shake profile holds that grey weathered appearance permanently.
Nantucket is a national historic landmark district with the strictest exterior review we work under anywhere. We start there rather than discovering a problem later.
Salt corrodes steel panels and fasteners continuously out here. Aluminum does not rust — which is the difference between a roof and a countdown.

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.
