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

This is our home county — we work out of 25 Walpole Park South. For Norfolk County homeowners that means the fastest estimates and closest supervision we give anywhere, and a roof you buy exactly once: lifetime aluminum, transferable warranty, no tear-off waiting for you in fifteen years.

We are headquartered in Walpole, not dispatching from another state. Estimates happen sooner, crews are supervised closely, and if anything ever needs attention we can be back the same week. Over a roof's lifetime that proximity is worth more than any brochure claim.
Norfolk's established suburbs — Wellesley, Needham, Brookline, Milton — sit under heavy mature canopy that keeps roofs damp and shaded. That is what feeds the moss and black algae streaking that makes an asphalt roof look finished years before it is, and shortens its life while it does. Aluminum gives that growth nothing to hold and nothing to absorb.
Many of the county's larger homes were built for slate, and a true slate replacement is heavy enough to require structural reinforcement. Interlock's aluminum slate profile keeps the roofline and skips the engineering bill.
One installation, a lifetime warranty, and it transfers with the house.

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
— Mark O., Tyngsborough, MA
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.
