Metal Roofing Manufacturers Near You: What a Local Search Really Finds

A search for metal roofing manufacturers near you usually returns three kinds of businesses: companies that make roofing, suppliers that sell it, and contractors that install it. What you need locally is the installer. For the Interlock® system, the manufacturer is Interlock Roofing in Delta, BC, and the only certified installer in New England is Interlock Metal Roofing (New England) Inc., based in Walpole, Massachusetts.

What does a search for metal roofing manufacturers near me actually return?

A local search for metal roofing manufacturers usually returns a mix of three types of business, and the results rarely label which is which. The first is the manufacturer: the company that forms the panels, applies the finish and writes the material warranty. The second is the supplier or distributor: a yard or branch that stocks panels, coil and trim for contractors. The third is the contractor: the company that comes to your house and installs a roof. Most homeowners actually need the third, a contractor, but they want the quality and warranty that come from the first. The useful question is not where the nearest factory is. It is which local company is trained and authorized to install a particular system, and who answers for the finished roof.

Does it matter how close the manufacturer is to your home?

The manufacturer's distance matters much less than the installer's. Roofing panels travel well, and a system made in one place is routinely installed far away. What does not travel well is accountability. If the people who put the roof on are a phone call away, a problem gets looked at; if they are hard to find, it may not. The Interlock® system is manufactured by Interlock Roofing at its plant in Delta, BC, and it is Made in North America. In New England it is installed by Interlock Metal Roofing (New England) Inc. from our office in Walpole, Massachusetts. We have installed Interlock® roofs in the region since 1999, and our Job Book records 5,036 completed roofs across the six states.

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

The difference is who is responsible for the finished roof. When you buy panels through a distributor and hire a separate roofer, the distributor's role ends at the sale of material. The roofer's role covers labor, and the material warranty sits with the manufacturer. If something goes wrong, you may be the one sorting out which party is responsible. With a certified installer, the material, the measurements, the crew, the flashing and the warranty registration all come from one company. Interlock® roofing is sold and installed only through the certified exclusive installer in each region, which means there is no second path to the product. That model exists because interlocking systems depend on correct installation, and the manufacturer wants trained crews doing the work.

Where do we install Interlock roofs in New England?

We install Interlock® roofs throughout Massachusetts, New Hampshire, Connecticut, Rhode Island, Maine and Vermont. The work ranges from older city neighborhoods in Massachusetts to shoreline homes in Rhode Island and Connecticut, coastal properties in Maine, and homes in the hills and ski country of New Hampshire and Vermont. The towns with the most Interlock® roofs in our Job Book include Brockton, Lowell, Worcester, Plymouth and Quincy in Massachusetts, Warwick in Rhode Island, and Manchester and Derry in New Hampshire. If you want to see finished work, ask us about roofs we have completed near you. Seeing a roof that has been through several New England winters tells you more than any brochure.

How should you check a local metal roofing contractor?

Check registration, insurance, written terms and finished work. In Massachusetts, residential home improvement contractors must be registered under M.G.L. c. 142A, and that registration gives homeowners access to the Home Improvement Contractor Guaranty Fund in some cases. In Connecticut, look for registration with the Department of Consumer Protection. In Rhode Island, check the Contractors' Registration and Licensing Board. New Hampshire and Maine have no state roofing license, so references and documents carry more weight. Also ask for proof of liability and workers' compensation insurance, the full warranty documents, and whether the crew is the company's own or subcontracted. Ask how the contractor handles chimneys, valleys and attic ventilation. If you live in a condominium or a historic district, ask how they work with associations and commissions.

How do you get an Interlock roof installed near you?

You start by booking an in-home roof consultation with our team. A consultant looks at your roof, attic and trouble spots, measures the house, and walks you through profiles such as Slate, Cedar Shingle, Shake, Mediterranean Tile and Standing Seam, along with the color range. You receive a written proposal for your roof. The Guardian Lifetime Limited Material Warranty covers material and finish for the original purchaser while they own the home. If the house is in a historic district, check with your local historic district commission. In a Massachusetts condominium, the trustees or association under Chapter 183A typically approve roofing work. Once the contract is signed, our crews schedule and complete the job.
