Review: April 22, 2004Completion: April 22, 2004

This letter is in regard to our recent purchase and installation of an Interlock Roofing System at our home on 7 Shingle Island Lane in North Dartmouth. We experienced a failing asphalt roof after only 14 years! After a bit of research on the internet, we investigated and decided on an Interlock Roofing System. Our salesman Michael Furman was outstanding. He was friendly, knowledgeable, courteous, and very professional and he answered all our questions pertaining to the materials and their installation. He assured us that our concerns on certain roof areas of our Log Home would be addressed and appropriate materials would be used. He was right! We have a beautiful new green Interlock roof that looks amazing with the dark stained logs! Alex and his crew did an outstanding job during the installation and especially paid attention to the details we were initially concerned with. The crew was hard-working, courteous, and always professional. They were very patient in answering ALL our questions about the installation and challenging areas around the Log dormers and multiple skylights. They worked long days showing much tolerance and patience despite all the rain, cold and wind March/early April threw at them! They made sure at each day's end to clean thoroughly and secure the worksite before leaving. Our neighbors have commented on what a great-looking roof it is and the great job the installers did as well. We've even had people drive down our street from the main road upon seeing the roof to comment on its outstanding look. Many of them have been following the progress since its start. We are so pleased with the final results! It is a very attractive, "rich" looking roof and makes our log home look once again like it was just built! We do highly recommend your product and your company to anyone who is considering a new roof. We are looking forward to a future without facing roof replacement again! Thank you for an excellent product and outstanding service from your company.

Review: May 31, 2005Completion: May 31, 2005

I am writing this letter to you and the installation crew that installed my Interlock Roof I have on my home. I would like to let you know how delighted and happy I am with my Interlock Roof. It was a pleasure working with you doing business with a company so professional as Interlock Industries, Inc. Everyone I spoke to was so helpful and very informative answering all the questions I had. My existing roof was only six years old when I noticed a brown spot on my kitchen ceiling, I couldn't believe a roof six years old was leaking needing repair so soon. I then began the process of looking for a solution. I was looking for a roof that would withstand the weather conditions in New England. I heard about the Interlock Roof from my friends. I began to read and learn about your product from my friends that had Interlock Industries, Inc. install their Interlock Roof couldn't say enough to me about how pleased they were with your product and how wonderful the company was to work with. I was pretty much sold on product. Then when you came to my home explained how this roof would be installed, the Lifetime " data-wpil-keyword-link="linked">Warranty - I knew this was for me and just what I was looking for. My home looks beautiful and best of all knowing I will not have to roof again makes me very happy with peace of mind. Thanks again especially for the superb service that was given to me. I would highly recommend the Interlock Roofing System to anyone interested in a new roof and never having to roof again.

Review: February 10, 2017Completion: September 30, 2016

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 " data-wpil-keyword-link="linked">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. " title="Ice dams" data-wpil-keyword-link="linked">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.

Review: October 18, 2004Completion: October 5, 2004

Dear Interlock, We are writing to inform you how pleased and satisfied we are with our newly installed roof. It was a big decision to make, and we were nervous at the time, but when our representative Mike Yaniv, explained and demonstrated the installation of the roof, he really made us feel more at ease. Alex, Dimitre and Dennis were the crew that worked on our roof. Not only did they do a very professional job – but they were also very polite, courteous and friendly. The job was completed in three days with very little mess, as Mike had told us at our first meeting. We were very impressed that the roof was done in such a timely fashion. Only half of the roof was finished, and our neighbors had already called to say they really liked the roof. Needless to say, when it was all finished, we received many compliments from our family and friends. We feel we made the right decision to go ahead with Interlock Roof and are glad we won’t have to worry about replacing it ever again. We would recommend this type of roofing and your company to anyone interested in replacing their roof. The roof looks great, and we are very happy!

Review: December 13, 2020Completion: November 11, 2020

From our first meeting with Jonathan, who was professional, authentic and knowledgeable about roofing, we've had a wonderful experience with Interlock Roofing. The installation team was clean, courteous and skilled at their job. The best part is snow slides off the roof and no more leaks in the house. Nothing. it was all great. It was great, easy to set up and we love the look of the roof

Review: August 26, 2017Completion: August 24, 2017

I can only speak from my experience with Interlock, but their communication, follow-up, installation, and quality have exceeded my expectations of any contractor. My roof is absolutely gorgeous and the talk of the neighborhood. The installers have gone about their work quietly, professionally, and respectfully (cleaning up my yard at the end of each day's work). I highly recommend this product and company to anyone looking to replace their roof with something gorgeous and enduring. This is one of the best decisions I've ever made for my home.

Review: June 28, 2014Completion: April 9, 2014

We love our new roof. We get tons of compliments. the slate style really matches the style of our house (built in 1690). Carefree for life. Overall, they did an exceptional job and were organized and professional. There was some slight mis-communication initially and I'm not sure where the link in the chain was broken, but it appeared someone was mis-instructed on which skylight to take out, either that, or he couldn't read the plans, but I'm not sure. In the end they remedied the problem. Sales person was very knowledgeable and friendly, but be prepared for him to overwhelm you with info (not a bad thing). We couldn't be happier with the product quality and look. Highly recommend this. They also offer financing which was helpful for us. see comments above questions 3 & 4 Best roof ever for quality and look

Review: June 7, 2007Completion: June 7, 2007

No more problems with moss and lichens, like I had with the " target="\_blank" rel="noopener">asphalt shingles. I am extremely happy with my new Interlock Roofing System and to think it has a lifetime warranty. There have been several rainstorms that last couple of weeks and to me the metal roof had added no additional noise at all. The flat roof is also a welcomed addition. The material quality is tip-notch throughout. A flat roof will normally wear out first; however, this also comes with a lifetime " data-wpil-keyword-link="linked">warranty. I have been impressed with Interlock from my first awareness at the local home show. I also did investigation through the " target="\_blank" rel="noopener">Better Business Bureau. During all interaction with Interlock, employees have been professional and courteous. The sales presentations were very informative. I was also able to visit half dozen houses locally that had had Interlock Roofing Systems installed. The benefits of the Interlock roof over an asphalt roof are numerous. In these days of rising energy costs and the high price of fuel, the expected energy savings are welcome. I will also be able to take advantage of the energy credit on my taxes this year. The fact that the ">roofing material deflects the heat versus absorbing it will make the house cooler during the summer months. Working with the installation team of Finn and Alex was a delight. The attention they gave to making sure things were done right was greatly appreciated. From the moment they arrived in the morning, till they went home at night, they were constantly working. During the installation period, there were several rainstorms. Alex and Finn always made sure they had things buttoned up before the storm started. We were lucky enough to get a couple of good days and they took advantage of them by working between 10 and 11 hours those days. If I saw anything that I did not like, it was quickly addressed or the explanation was given why it had to be done that way. The answer was always acceptable to me. They took the time to help me understand the various installation tasks. The longevity of Finn and Alex’s careers with Interlock are testimony to Interlock as a company, their product knowledge and experience levels, and work quality. I would highly recommend Interlock Industries roofs to others.

Review: April 9, 2006

My wife and I met Mike Furman at the Home Show in Foxboro this past winter. I had asked about the system in other years but got so turned off by the salesperson I never stayed to talk. This year was the first time we’ve seen Mike. We started to talk with him and were readily put at ease. We were so comfortable talking with Mike that we agreed to have him come to our home and really talk business. Mike has a wonderful way of explaining the Interlock system. Not only is he intelligent and professional, but he is also patient. He never talked down to us or over our heads. He was always neatly dressed but not in a stuffy business suit, someone you could relate to. The roofing crew led by Bakha, Alex (a great craftsman!) and the rest were a pleasure to deal with. They were very polite and accommodating. They worked some very hard, long hours to get the job done. They had to work around New England’s typical weather: sun, rain, " data-wpil-keyword-link="linked">hail, snow and wind. The weather delayed them a little, but they were soon done with the job. They cleaned up each night before they left, so we never had to worry about getting nails in our car tires. The roof, it’s beautiful! It complements the style and design of our house. My wife said she had never looked at our roof much before, but now she stops in the driveway to admire it. Our biggest concern about it being noisy in the rain was taken care of. Mike was right! You really don’t hear the rain any more than before. About four years ago, a friend of mine, George, from Berkley, MA, had gotten a metal roof. He loved it and always talked well about it. He has been answering my questions about it over the years and invited my wife and me to see it before we bought it. His is the Interlock system too. Since I’ve been talking to George for the past four years about your roofing system, I believe he should be given a “finders fee.” Thank you.

Review: November 28, 2002Completion: November 27, 2002

I wanted to let you know how happy my wife and I are with our new Interlock roof and the quality of the installation work. The installers presented themselves in a very professional manner. They took great pride in their job and worked on our home as if it was their own. At the end of the day, they always cleaned up after themselves and never inconvenienced my family. They truly were a wonderful crew! The roof looks fantastic. It is much sharper and cleaner looking than our old roof. Since it was completed, we have had several hard rainstorms. The roof performed very well. One of our initial concerns was if rain hitting this new roof would be louder than our old. On those stormy nights, our fears were quickly put to rest. There was no difference in sound compared to our old roof. Then, the night before Thanksgiving, we had a snowstorm. Thanksgiving Day was nice and sunny, and our house was the only one with no snow on the roof. The Interlock roof is, by far, the best home improvement project I have undertaken; it is wonderful knowing I will never have to worry about my roof again. Thanks for the great product and service.

Metal Roofing FAQs for Homeowners in Polpis

The following metal roofing FAQs are designed specifically for homeowners in Polpis, Massachusetts. Whether you are building a new home or replacing an existing roof, understanding how roofing materials perform in local weather conditions is essential. From wind and storm protection to fire resistance, hail impact, snow loads, and coastal moisture exposure, Interlock’s Lifetime Aluminum Roofing System is engineered to provide long-term durability, energy efficiency, and peace of mind in Polpis.

How does a metal roof handle Polpis's annual snowfall and ice buildup?

Metal roofs shed snow and ice more effectively than asphalt because their smooth, hard surface prevents snow from bonding and creating dams. Polpis receives about 62 cm of snow annually, and the lightweight aluminum panels (the Slate profile weighs just 0.41 lb/sq ft) mean snow loads don't stress your structure. The four-way interlocking system is warranted for wind gusts up to 160 km/h, so winter storms won't lift or separate the panels. Many homeowners add snow guards if desired, but the design itself resists the freeze-thaw cycling—about 44 days per year here—that causes asphalt and wood to crack and curl over time.

Why does Polpis's freeze-thaw cycle damage some roofing materials but not aluminum?

Freeze-thaw damage occurs when water penetrates a material, then expands as it freezes and contracts as it thaws—gradually cracking it apart. With around 44 freeze-thaw days annually in Polpis, asphalt shingles and wood shake eventually fail this way. Aluminum cannot absorb water; it's non-porous and its protective oxide layer actually self-heals when scratched, staying intact through countless cycles. The Alunar 70% PVDF coating (warranted 30 years against chalking and fading) adds a second defensive layer. After 1157 mm of annual rainfall, this sealed-surface approach keeps your roof sound for decades where organic materials would be degrading.

Does metal roofing rust in a coastal climate like Polpis?

Aluminum cannot rust because it contains no iron—the chemical element required for rust formation. The material is roofing-grade 3105-H24 or 3003-H24 aluminum alloy per ASTM B209, and its protective oxide layer resists corrosion even in salty air. Interlock has installed panels at coastal homes and even an Antarctic research station, proving durability in extreme salt-air environments. The Alunar finish, applied to both sides of every panel, provides an extra 30-year warranty against chalking and fading. Steel roofing, by contrast, requires constant maintenance and will eventually rust; aluminum's passivity means you maintain the structure, not the material itself.

How does a metal roof perform during Polpis's heavy rainfall?

The four-way interlocking system and proper underlayment create a dual-defense barrier against Polpis's 1157 mm of annual rainfall. Each panel locks to its neighbors on all four sides, so water sheds away from seams rather than into them. When installed over solid decking with standard underlayment, the system handles heavy downpours the same way your asphalt roof does—water simply runs off. The ICC-ES evaluation report (ESR-1790, reissued 2025) confirms code compliance for water management in all climates. Unlike asphalt, which absorbs moisture and degrades, or wood shake, which rots, aluminum sheds water indefinitely without deterioration.

Can reflective metal roofing reduce cooling costs in summer?

Yes—energy-efficient Interlock colors reflect up to 55% of the sun's heat away from your home instead of absorbing it like asphalt does. The coating's thermal emissivity is 0.84, meaning it efficiently radiates away any absorbed heat. With 3081 sunshine hours per year in Polpis, this reflectance compounds over months. Cool Roof Rating Council certification backs these measurements. The lightweight panels also require no structural reinforcement and install over most existing roofs, so upgrading to an energy-efficient color is faster and less disruptive than a tear-off. Over decades, lower cooling loads translate to measurable savings on air-conditioning energy.

Does hail damage metal roofing, and can it lower insurance premiums?

Interlock metal roofing carries a UL 2218 Class 4 impact rating—the highest hail classification available—and the warranty even covers perforation from hailstones up to 1.5 inches. This durability sometimes qualifies homeowners for insurance discounts on comprehensive coverage. Polpis's coastal storm exposure is real, and Class 4 impact resistance demonstrates measurable, third-party-verified toughness that underwriters recognize. The four-way interlocking panels distribute impact loads across a wider area than traditional shingles, reducing localized damage. If hail strikes, you're protected by warranty rather than facing repeated claims and premium increases.

How strong are the wind gusts in Polpis, and will metal roofing stay secure?

Polpis experiences typical daily-max winds around 29 km/h but can see gusts up to 160 km/h during storms—and Interlock's four-way interlocking panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. The interlocking design means each panel is mechanically fastened and locked to its neighbors, so wind cannot lift individual shingles or create the flutter that weakens traditional roofing. This warranty is backed by real installation data spanning over 25 years across North America's most variable climates. Your roof's integrity in winter nor'easters and summer squalls is guaranteed by engineering, not hope.

Can metal roofing be installed over my existing asphalt roof?

Yes—one of aluminum's key advantages is weight. The Mediterranean Tile profile, for example, is about 96% lighter than concrete or clay tile, so it installs directly over most existing roofs without requiring structural reinforcement or a costly tear-off. Your contractor will assess the existing deck and add underlayment as needed, then fasten the interlocking panels according to the ICC-ES evaluation (ESR-1790). This means lower labor costs, no landfill waste from ripping off old asphalt, and you're under your new roof sooner. The local installer, Interlock Metal Roofing (New England) Inc., has served the region since 1999 and handles the entire process from assessment through final inspections.

What warranty does Interlock metal roofing offer, and is it transferable?

The Guardian warranty is a lifetime limited, non-prorated material warranty for the original owner—covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It's also one-time transferable to the next owner, who receives coverage for 50 years from completion. This structure reflects the product's real durability: aluminum manufactured since 1998 in Delta, BC has proven itself in thousands of installations from coastal to extreme climates. Unlike asphalt warranties that prorate over time or require you to chase roof-specific coverage, this single comprehensive warranty simplifies your peace of mind and adds resale credibility. The Alunar coating alone is warranted 30 years against chalking and fading.

Is metal roofing more environmentally responsible than asphalt shingles?

Yes. Aluminum is approximately 95% recyclable at end-of-life, whereas asphalt shingles become landfill waste—millions of tons annually across North America. When you tear off an asphalt roof after 15-20 years and replace it again, you're creating disposal costs and environmental impact. Interlock's lifespan means far fewer replacements over your home's lifetime, eliminating the tear-off-to-landfill cycle. The material itself is engineered to resist the 44 freeze-thaw days and 1157 mm of rainfall Polpis receives, so you're not replacing it early due to climate damage. CALGreen verification confirms reduced maintenance demands, which means fewer service calls and less resource consumption. Choosing aluminum is choosing durability and circular economy over planned obsolescence.

Is a metal roof a good choice for Polpis’s climate?

Yes. Polpis averages about 62 cm of snow, 1157 mm of rain, roughly 44 freeze–thaw days a year, with peak wind gusts near 160 km/h. Interlock® aluminum roofing is wind-rated to 193+ km/h (120 mph), UL 2218 Class 4 impact-rated and Class A fire-rated, and its four-way interlocking panels shed snow and resist ice dams and freeze–thaw cracking — all backed by a lifetime limited, transferable warranty.
