Where to Buy Aluminum Shingles in New England

Where can you buy Interlock aluminum shingles in New England?

You buy Interlock® aluminum shingles in New England from Interlock Metal Roofing (New England) Inc., which has been the certified and exclusive Interlock® roofing contractor for the region since 1999. We serve Massachusetts, New Hampshire, Connecticut, Rhode Island, Maine and Vermont from our office in Walpole, Massachusetts. The roof is sold as a complete, installed system. That means one company measures the house, orders the panels, trim and flashing for that specific roof, installs them with trained crews, and registers the warranty. You won't find Interlock® shingles stacked on a lumber yard shelf or listed for pickup, and that is by design. The manufacturer makes the system to be installed a particular way, and the exclusive installer model is how it makes sure that happens.

Why aren't premium aluminum shingles sold as loose panels?

Premium interlocking aluminum shingles aren't sold loose because the roof's performance depends on installation as much as on the metal. A four-sided interlocking panel only resists wind and driven rain if the starter, fastening pattern, ridge, edges and flashing are all done correctly. Most of the hard work on a New England roof happens at the details: brick chimneys on a Cape, multiple dormers on a Victorian, valleys where additions meet the original house, and skylight curbs. Those details are formed and fitted on site. A crew that installs the same system every week knows how the pieces fit together and where water tends to find its way in. A crew trying a product for the first time is learning on your house, and that is a risk no warranty paperwork fully covers.

How does buying through the installer affect your warranty?

Buying through the certified installer is what connects your roof to its warranties. The Guardian Lifetime Limited Material Warranty covers the Interlock® material and finish for the original purchaser while they own the home, and it is transferable once, with the second owner covered to 50 years from substantial completion. The 30 Year Alunar® coating warranty covers the finish. Because we install the roof, we also register it, and we keep the records of what went on your house. Workmanship is not part of the material warranty. If something needs attention, there is one company to call.

What is the difference between buying from a supply yard and a certified installer?

The difference is accountability. When you buy panels from a yard and hire a separate roofer, the supplier sold you material and the roofer sold you labor. If a leak shows up at a chimney two winters later, each may point to the other. With a certified installer, one company answers for the material choice, the measurements, the crew and the finished roof. Crews that install one system full time also tend to carry the right brakes, trim profiles and fasteners for it, rather than adapting parts meant for something else. None of this means supply yards are bad businesses; they serve contractors and builders well. It means a system roof with long written warranties is a different kind of purchase from a pallet of panels.

What should you check before hiring any roofing contractor in New England?

Check state registration first, then insurance, references and written terms. In Massachusetts, contractors doing residential home improvement work must be registered under M.G.L. c. 142A, which also gives homeowners access to the Home Improvement Contractor Guaranty Fund in some cases. Connecticut requires home improvement contractors to register with the Department of Consumer Protection. Rhode Island contractors register with the Contractors' Registration and Licensing Board. New Hampshire and Maine have no state roofing license, so references and paperwork matter even more there. Ask for proof of liability insurance and workers' compensation, a written contract with the scope and the warranty documents attached, and addresses of finished roofs you can drive past. Ask every contractor you interview, including us, for their registration numbers and check them with the state.

How do you start buying an Interlock roof from us?

You start with an in-home roof consultation. A consultant visits, looks at the roof, the attic and the problem areas, measures the house, and talks through profiles and colors. Interlock® offers Slate, Cedar Shingle, Shake, Mediterranean Tile and Standing Seam profiles, plus solid copper, in colors from Black and Deep Charcoal to Colonial Brown and Hunter Green. You then receive a written proposal for your specific roof. If you live in a historic district, check with your local historic district commission before you finalize the look. If you own a condominium in Massachusetts, your trustees or association under Chapter 183A will usually need to approve the work. Once the contract is signed, we schedule the installation, handle the work with our trained crews, and register the warranty when the roof is complete.
