The new roof started earning its keep the day after it was finished
Haverhill, Massachusetts
The experience with the entire Interlock team was a pleasure. First having Mike come out to give an estimate and his patience with making a decision, to scheduling and other matters with Jennifer in the office and finally Igor and his crew. Igor and his crew worked really hard, their workmanship was more like craftsmanship. They were very respectful and treated our home and property like it was their own. When they completed the job you did not know they were even there, except for the beautiful new roof.
The new roof started earning its keep the day after it was finished, due to a bad rainstorm. Throughout this winter we were amazed that once the snow had fallen off the roof, we were the only home in the neighborhood to have no snow or ice.
Our advice to any homeowner is to take the leap and get an Interlock roof, you will not regret it.

I highly recommend metal roofing
Norwell, Massachusetts
We have had significant damage due to water leaks inside our house over the past 5-6 years. The reasons behind these leaks were ice dams and icicles. Our house is facing north. It gets minimum or no direct sun exposure most winter months. Repairs were costly. The problem, however, would recur every winter. Our roof was about 15-year old and it was not in a bad shape. We had a contractor installing a reinforcement felt in the area of interest (cost about four thousand dollars labor and material) but failed to correct the issue.
After a thorough research, we were left to choose between electrical panels or a metal roof. We opted for the later, for both, safety and aesthetic reasons. We found Interlock Industries through internet-Google- search. We are pleased with our 2 choices (metal roof and Interlock) for the following reasons, with few remarks:
Estimate and contract
Done properly, in a pressure-free environment. Larry Ebbs understood and executed his role well.
Communication and coordination
With the central office were excellent (Jennifer Simons)
Execution
A highly professional crew. Neat, detail-oriented, highly efficient, and courteous workers. Two caveats:
- The crew who worked on our house was not fluent in English, and communication, when occasionally needed, had to happen over a cell phone.
- The start was phenomenally fast; completing the job dragged a bit longer.
Cost
Expensive upfront. About 3 times the cost of a shingle roof; cost will go down to about 2.5x with discounts and incentives. Financing option is available, but the interest rate is relatively high. A tax credit is available since (Interlock) metal roofs are energy efficient.
Head Roofer
Paul McAllister is outstanding (as a person and as far as quality of work). In addition to the metal roof, Paul and his crew successfully fixed a chronic leak from a small flat roof in the back of the house. This is a leak that we tried to repair at least twice (different contractors) without success.
Results
* Functionality: We have had 2 major snow storms this winter, between 12-15 inches of snow each time, comparable to prior years. We are delighted to announce that we have not had any leaks. Ice dams continued to form, mainly in the northern section of the house (where the insulation, we believe, is imperfect), but they are much smaller in size and fewer in number. No further icicles noted (make sure you don’t stand underneath the roof after a snowy day, as the snow slides off the roof like an avalanche). One downside is the noise caused by the rain drops. This noise is here to stay and will bother some people.
* Appearance: The roof look is outstanding. Sharp and perfect geometry. The color contrasts nicely with the paint.
Overall
If you live in a snowy region, and you are planning on replacing the roof of your home for functional or aesthetic reasons, or for both, I highly recommend metal roofing.
I also recommend metal roofing for new constructions in these areas as well.
If you decide to go with a metal roof, Interlock Industries (New England) will meet or exceed your expectations.

Superior product which is energy efficient, color fading resistant for many years, weather and wind resistant, and environmental friendly
The house is 16 years old. The roof tiles were beginning to curl and I thought it was time to get a new roof. I consulted a company I had employed in the past and they offered me a roof with a 50-year warranty for about $28,000. I told my optician about their offer and he told me not to use them but to try Interlock. He had had a good experience with Interlock and recommended them to me. He gave me the BBB number to make the connection.
Interlock offered me a limited lifetime warranty with a far superior product which is energy efficient, color fading resistant for many years, weather and wind resistant, and environmental friendly made of 95% recyclable material. Up to a degree it is fire resistant, too. Pigeons are not attracted to it and that is marvellous because before I had a lot of pigeons sitting on top of it and getting a lot of droppings from them. Not now.
The work was done in about a week and a half. The workers worked constantly and were courteous and friendly. All spoke Spanish, my mother tongue. That made it pleasanter. I was surprised Hispanics were involved in this industry. Now I have a new roof from Interlock, new gutters from Leaf Guard, and new windows and doors from the Power Remodeling Group, all with a limited lifetime warranty. As a senior citizen, I cannot ask for anything more as my income becomes fixed in a few years.

New Boston Metal Roof Installed | Smooth Process, On-Time Delivery, and Expert Support from Chris L.
In Boston, where history and innovation converge, homeowners like Jessica make choices that stand the test of time. Situated along the Atlantic coast, Boston’s climate presents a unique set of challenges: salt-laden air, heavy snowfall, and gusty Nor’easters. These conditions demand a durable and resilient roofing solution that provides a sense of security and peace of mind.
Jessica’s experience with Interlock Metal Roofing exemplifies this pursuit of excellence. Opting for the Black Interlock Slate Shingle Metal Roofing System, she found a product that not only offers unparalleled performance but also enhances the aesthetic appeal of her home. In her words:
Top 10 Roofing FAQs for Boston, MA Homeowners
What is the best type of roof for Boston’s climate?
Boston sees hot, humid summers, freezing, snowy winters, and coastal wind and salt air. That means your roof needs to be corrosion-resistant, insulated, and able to withstand wind and ice loads. Interlock Metal Roofing, made from high-grade aluminum, is engineered for this climate. Unlike steel, it won’t rust. Unlike asphalt, it won’t crack or curl. And it sheds snow naturally—reducing the risk of ice dams.
How does Interlock Metal Roofing compare to asphalt shingles?
Asphalt shingles are common in Boston, but they often need to be replaced every 12–20 years due to New England’s weather. They can deteriorate from snow, sun, and algae growth. Interlock aluminum shingles last 50+ years, come with a Lifetime Limited Warranty, and won’t absorb moisture, crack, or fade like asphalt.
Is aluminum roofing better than steel roofing for Boston homes?
Yes. While steel is strong, it’s prone to rust, especially in coastal neighborhoods like South Boston, Dorchester, and Winthrop. Aluminum doesn’t rust—ever. Interlock uses a marine-grade aluminum alloy with a protective Alunar finish that stands up to salty air and acidic rain.
How does Interlock compare to synthetic or composite slate?
Composite slate is lighter and more affordable than natural slate but may fade or become brittle over time. Interlock Slate Shingles offer the look of real slate with superior weather resistance, and the aluminum core resists cracking and UV damage. It also weighs significantly less, making it a better fit for older Boston homes.
Is Interlock Metal Roofing suitable for historic Boston homes?
Absolutely. Interlock offers classic profiles like Slate, Shake, and Tile in colors that complement historic architecture in neighborhoods like Beacon Hill, Back Bay, and Cambridge. And because it’s low-profile and elegant, it preserves curb appeal while dramatically increasing performance.
What about rubber roofing—why not use that?
Rubber roofing (EPDM or TPO) is typically used on flat or low-slope roofs—like those on multi-family row homes or small additions. It’s not ideal for pitched residential roofs. While affordable, rubber can shrink, crack, and attract debris over time. Interlock’s pitched roofing systems are better for homes needing aesthetic value + longevity.
Does Interlock help reduce energy costs in Boston homes?
Yes. Interlock roofs are coated with heat-reflective Alunar Coating System that help reduce heat absorption—keeping your home cooler in summer. This is especially useful for triple-deckers and brownstones with full-sun exposure on the roof. Helps lower attic temps = lower AC bills.
How does Interlock handle snow and ice in Boston winters?
With its 4-way interlocking design, snow and ice stay out. The smooth metal surface also sheds snow naturally, preventing heavy buildup and reducing the chance of ice dams. No need for dangerous rooftop snow removal every winter.
Will it hold up to wind and storms?
Yes. Boston’s nor’easters bring wind gusts that can rip up shingles and flashings. Interlock systems are rated for high-wind performance, thanks to their interlocking panels and secure fastening system. Your roof stays in place—even when the weather doesn’t.
Is Interlock Metal Roofing a good long-term investment in Boston?
Absolutely. While the upfront cost is higher than asphalt, Interlock’s lifetime warranty, low-maintenance, and lasting curb appeal make it a smarter choice for Boston homeowners who don’t want to re-roof every 10–15 years. You get peace of mind—and one less project to think about.
If you live in Boston, you need a roof that handles snow, salt, heat, and wind without falling apart. Interlock Aluminum Roofing checks every box: it’s rust-proof, energy-efficient, wind-rated, and architecturally beautiful. It’s a roof you install once—and never think about again.

Snow easily slides off and does not build up a snow load
Dear Mr. Michael Baldassari,
My wife and I would like to express our satisfaction with your metal roof installation on our house. The roof was installed in late November of 2009, only a few days before we received our first major snow fall. Your roofing crew was extremely professional and their work exceeded our expectations. They installed our roof in an efficient and careful manner; working tirelessly for two and a half days. At completion, they did a fantastic job of cleaning up the yard around the house.
In particular, we have really appreciated one of the advantages that your metal roof offers. Snow easily slides off and does not build up a snow load. After the second snow fall, I gave away my snow rake knowing that I would never again have to get on an extension ladder to clear a two and a half story roof. Due to the size of our roof, in the past, this task has taken several hours and has been somewhat hazardous. I certainly won’t miss this “pleasurable task” of home ownership.
Last week on Thursday evening, the 25th of February, we had rain, snow and wind gusts up to 68 miles per hour for several hours. The roof received punishing forces from the wind as well as flying debris from tree branches and pine cones. We were a little concerned that we would see roof damage the next morning. However, upon inspection, the roof remained intact. The resistance to such forces demonstrates how well the metal roof has been installed and the topnotch quality of the metal roofing material itself.
Knowing that we will never have to replace our roof again has convinced us more than ever that we made a wise investment. The aesthetics of the black metal roof has added a richness and quality finish to our home which we will enjoy for many years to come.
Sincerely,
John and Jane Vaitkunas

Dear Interlock,
This letter is in regards to the absolutely gorgeous roof you recently installed for us.
The roof looks amazing. The red choice was a little nerve racking, but it is even better than we could have imagined. We live on a very busy street and we can often hear cars slowing down in front of the house to look at the roof.
Mike met with us in mid March and was extremely knowledgeable about the product and answered all our questions. When we were ready to proceed with the project. Miranda was very helpful and courteous to us. Within a couple of days of getting the go ahead for the project, one of Interlock’s installers was at our door, saying they would be starting the next day. He notice something that was missed in the initial roof review and suggested we add some ice guards above our skylights for extra protection. They started the next day promptly at 8am and with fear of rain the following day they worked til well after dark and then picked up the debris from our yard and took it away with them. They also carefully covered the additional materials to be used in case of rain. They finished the project in a couple of days and cleaned up every day before they left. The installers were very polite and worked hard to get the project completed.
We plan on staying in our home for many years to come and are pleased with the decision we made to go with the Interlock Roofing System. Both for the beauty it adds to the exterior of our home, the immediate savings coming over our way with reduced heat and electricity bills and the long term benefit of never having to replace the roof again.
Sincerely,
Christopher and Danon Perry

Birthplace of the American Industrial Revolution
Lowell is known as the “Cradle of the American Industrial Revolution.” It was one of the first cities in the United States to industrialize, with its famous textile mills leading the way in the early 19th century. The city was a major center for cotton and textile manufacturing.

The Lowell Mill Girls
The “Lowell Mill Girls” were a significant part of the city’s history. They were young women, often from rural New England, who came to work in the mills. They lived in company boarding houses and were among the first to organize labor protests and strikes in the U.S., advocating for better working conditions and shorter hours.
Lowell National Historical Park
Lowell is home to the first urban national park in the U.S., the Lowell National Historical Park. The park preserves and interprets the city’s role in the Industrial Revolution, featuring historic mills, canal systems, and a network of museums and educational centers.
The Spindle City
Lowell earned the nickname “The Spindle City” due to its dominance in textile manufacturing. At its peak, the city had dozens of mills, and thousands of spindles were in operation, producing massive amounts of cloth daily.
A Diverse Immigrant History
Lowell has a rich history of immigration. It was a melting pot for many immigrant groups, including Irish, French Canadians, Greeks, Portuguese, and more recently, Cambodian immigrants. Today, Lowell has one of the largest Cambodian communities in the United States.
The Jack Kerouac Connection
Lowell is the birthplace of Jack Kerouac, the famous Beat Generation writer known for his novel “On the Road.” Kerouac often referenced his hometown in his writings, and there is a park, the Jack Kerouac Commemorative, dedicated to his memory in downtown Lowell.
Canal System and Waterpower
The city’s intricate canal system was engineered to provide waterpower for its mills. The canals are still in place today and are a central feature of the Lowell National Historical Park. Visitors can take boat tours to learn about the canal system’s history and function.
The Merrimack Repertory Theatre
Lowell is home to the Merrimack Repertory Theatre (MRT), a professional theater company that is well-known in New England for producing contemporary plays and supporting new works.
The Tsongas Center
The Tsongas Center at UMass Lowell is a multipurpose arena that hosts concerts, sporting events, and other entertainment. It’s named after U.S. Senator Paul Tsongas, a Lowell native who was a significant political figure in the state and the country.

Dear Interlock Management,
As promised I am writing you a follow up letter sharing our experience regarding the purchase and installation of our new Interlock Roof.
Long before we received your introductory mailing my wife and I had already had our minds set on eventually installing an Interlock Roof. Our reasoning was simple. We only wanted to install one more roof in our lifetime, and we were very interested in the looks, durability and warranty of your product.
As an experienced service and installation manager myself, I am very familiar with the fact that many jobs have their surprises, and sometimes despite planning things go wrong. What really matters is how those instances are dealt with. As in our case, the first day the crew did not arrive until several hours later than expected due to issues back at the warehouse. The Customer Service Manager I believe, Miranda was very apologetic and did try to explain as well as got back to me with status on their expected arrival.
The late arrival was quickly put behind us as upon arrival your crew without walking around or discussion divided and began what was a dynamic, organized and efficient process of setting up and beginning installation like nothing we or our neighbors have ever seen. In just a few hours they had stripped two layers of roofing off the house and garage, did some repair work, papered the roof and had half the garage and the front half of the main roof complete.
On day two they completed the install and did an incredible job of cleaning up. This included every member of the crew walking my property to insure not one nail was left to step on, or cause tire damage. Our second surprise or problem was detected after their departure which was related to the fact that the back half of our roof had to be done in neoprene and the drip edge was not only different but was white instead of black causing our roof to look incomplete. I believe we both learned something that day. Your company for the future will be able to point this out up front and offer to paint the the edging in advance of the installation. In our case you had a man here the next day and he painted the drip edge to match the front half of the house and shingles. We also had two separate follow up visits from your quality control people to inspect the job for proper install and completion.
In summary we are very pleased with our roof and the diligence of your hard working, professional crew.
We without a doubt have the best looking roof in the neighborhood, bar none.
Sincerely,
Dave Marr
Lowell, MA
