During hotdays the house seems cooler and the snow slide off during winter

December 30, 2022

We love the stylish new look our house got with the Metal Slate Roofing and the longevity Interlock Roof System offers. Although the roof is made of aluminum, the design makes the roof look as if it was traditional slated roof, hard to tell it is even metal. The crew professionally installed the new roof in no time. It has only been a few months since Installed but we have seen already some of the benefits. During hot days the house seems cooler and the snow slide off during winter. And the lifetime limited non-prorated roof warranty give us peace of mind.

The new roof is not only super functional for our New England location, but it also looks beautiful!

December 2, 2022

We had a new metal roof installed on our entire home, and we are very pleased with the quality of the product. Our installation had to be scheduled for after some other work being done on the house, and Interlock was very flexible with our ever-evolving timeline. As soon as we were ready, they had a crew at our house within a week and once started they were very quick to get the project done. The new roof is not only super functional for our New England location, but it also looks beautiful!

I’m still amazed at how good the metal roof looks

August 22, 2022

Positive: Professionalism, Punctuality, Quality, Responsiveness, Value The roof on our vacation home in New Hampshire was about 15 years old and was starting to lose shingles due to deterioration and weather and needed to be replaced. After seeing many homes in the area converted to metal roofs, I started researching this and decided that this was the way to go. As with all projects, I like to get multiple quotes from vendors. I made contact with the folks in Walpole for Interlock and soon after I was contacted by Mark. He came out to the site to review the project and provided multiple options and a professional quotation. We selected the shake-style metal rooftop to replace the current asphalt shingles. Once the decision was made and the contract signed, A small team of professionals took care of making sure the project was completed to our requirements. We had issues with squirrels getting into the house through the ridge vent and had another contractor fix the issue on the old roof. I expressed this concern to Mark, and he made sure that the new roof would provide the same protection. The new roof was installed on schedule over the winter in New Hampshire and looks beautiful. The crew was neat and orderly and left no mess behind. Mark was always available to answer questions regarding any aspect of the job. This made it easier for us as we live 4 hours away in Connecticut and to know that your concerns were being taken care of was a huge relief to us. I’m still amazed at how good the metal roof looks whenever I’m at the house, and I would recommend Interlock to anyone interested in a new metal roof. Service: Roof installation

We had a metal roof installed to replace our asphalt roof

August 2, 2022

Positive: Professionalism, Punctuality, Quality, Responsiveness We had a metal roof installed to replace our asphalt roof. We were very happy with the workers that were here every day and on time. They were very professional and each day they cleaned up all debris before leaving for the day. The roof is just what we wanted and are very happy with it. We would recommend Inter Lock very highly.

We suffered a house fire that destroyed a large portion of our home

July 6, 2022

Positive: Professionalism, Quality, Responsiveness We suffered a house fire that destroyed a large portion of our home. After researching multiple metal roof options and comparing quotes from three different installers we selected Interlock without hesitation. The product design was important to us and we were impressed with the materials and finishes and believe it will last a long time. The slate styling was a definite upgrade for our roof. It sheds snow easily and completely and still looks new after two years so far. The warranty offered speaks volumes for the company. We have already recommended this roof to friends and I saved some scraps from the installation to show them how unique the design is! Services: Roof installation, Roof repair

We absolutely LOVE our roof!

December 2, 2021

Positive: Professionalism, Punctuality, Quality, Responsiveness, Value We absolutely LOVE our roof! Right from the start, this company worked with us every step of the way. Beginning with the quote, the financing, the install to the clean up. They were professional, friendly, fast and understanding in all our questions and concerns about making this big purchase. We highly recommend Interlock if you are considering a new roof; you won't regret it! Service: Roof installation

My husband and I knew we had found the right company

September 21, 2021

Positive: Professionalism, Punctuality, Quality, Responsiveness, Value From the word Hello, my husband and I knew we had found the right company. We went direct to the Mfg, eliminating the middleman because Interlock has their own crews installing the roof. I never have to play the game of whether it's the contractor's fault or not; it's the Mfg's fault IF there is ever an issue with my roof! Their Salesmen Mark, was always in contact with me, as is their business office - Jennifer was great - even when we delayed the job because of issues with our home out of our control. Once we gave the green light, their installation team was here within days and done within three days. They addressed rot we hadn't anticipated, brought in their inspector to ensure the job was going smooth and answered questions we had. We are very shy with contractors due to a couple of misfortunes, so we were very leery about going with any contractor in general. We have renewed hope there is good in this world. I couldn't be happier with not only the product but the company. WE LOVE OUR ROOF! The best part is I'll never have to worry again, and I can transfer my home into trust with confidence my family won't have to worry again either! Thanks, Interlock!

No more ice dam on my low slope roof

June 17, 2021

Somersworth NH install. Great group of workers. They had the foreman check all work after. They are easy to contact, the price was ok, it's not asphalt, and you get what you pay for. Don't expect a price like an asphalt roof. I liked heavy gauge aluminum over those coated steel roofs. They can rust over time. Aluminum does not rust. I had it for over 1 year, with no issues, no leaks, snow falls good, and no more ice dam on my low slope roof. I even climbed up there to seal a few hairline cracks in my chimney mortar. Nice and durable. It's worth it in the long run. The only thing I would recommend is please attach the siding near eaves security. Because as they insert flashing, they may need to pull out a few areas and nail them back. Just pay attention. There was one little loose area that was nailed in on my siding but needed to be locked in from the bottom. Overall great company, I do; the roof was secure, no loose shingles or flops. I highly recommend this company. I think the two areas near the eave of siding were done ok; they just needed the final touch. And it wasn't even roof related. And the small siding area lasted a year till I had a heavy windstorm. I replaced that small area, and since ok. Just to be clear, my siding is older; it locks in differently. Don't get the impression that they leave things floppy. Just have them check and pull on and areas they removed siding at the end. Service: Roof installation

What a great install team, polite, good quality work

September 1, 2019

We just had our interlock slate roof installed. What a great install team, polite, good quality work, had people there only to do clean up all day long, and fast. They answered any questions we had on the installation and addressed things right away we wanted to be changed. We are so happy with the product, and the installation left our porch cleaner than when they started! So happy with it and highly recommend the company. Quality product and installation team.

Our Interlock Metal roof is all we had hoped it would be!

July 21, 2019

Our Interlock Metal roof is all we had hoped it would be! Folks often stop by and ask about it. We direct them to the company with complete assurance that they will be as happy as we are. My photo doesn't capture the bright blue color. When locals give directions that include our home, it is referred to as the "happy house." Every season looks even more beautiful surrounding our home. The men who worked on it could not have been nicer, more thorough, or more patient with us! Service: Roof installation

The higher cost of an interlock roof has been worth every penny

Interlock installers were great to deal with. They completed the job in half the time that was quoted. The one minor discrepancy I found two months after installation was fixed by an Interlock representative less than twelve hours after reporting it. The higher cost of an interlock roof has been worth every penny and I’m not even through my first winter yet.

The hail was almost golf ball sized... There were no dents in the roof

We just had a flash-hail storm the other day. It tested our roof, and it did very, very well. The hail was almost golf ball sized, and it lasted for about five minutes. We didn’t hear the rain, but boy did we hear that hail. It sounded like machine guns going off against the walls and roof. I haven’t seen hail like that since I left Texas. There were no dents in the roof, and there were no blemishes. It held up beautifully.

The payback more than covers the extra price

January 19, 2015

I had an Interlock roof put on several years ago and I am not sure I agree with the statement “more expensive, sure”. While it does cost more to put on the roof, I think the payback more than covers the extra price. I am sitting in my attic office, a place that got cold even with the heat this time of year, it is warm now. It stays cooler in the summer as well which saves on cooling costs. The sales person told me that it would be the case but I really didn’t believe it. I would buy this roof again in a heartbeat.

We chose Interlock to install a much needed new roof on our 200-year-old farmhouse

We chose Interlock to install a much needed new roof on our 200-year-old farmhouse in Warner, New Hampshire which serves as our year-round vacation getaway. From the moment David showed up to meet with us through the final completion of the project a few weeks ago, we knew that we had made the right decision and that our project was in good hands. We never once felt pressured even though we took longer than expected to complete some preliminary repairs to a porch roof before the project could begin. When we did finally call to say that we had completed our work and were ready to go, they had a work crew on site in less than a week! More amazing is that they completed their work of stripping the old asphalt, installing a plywood deck, and re-roofing a large old house where nothing is truly square in five days and, other than the evidence of a brand new gray slate roof on our house, one would never know that anyone had even been there. The crew left our property cleaner than it was before they arrived. They even cleaned up a pile of roofing debris we had left behind following our re-roofing project. Throughout the project, David and Jennifer, in the office, were always available to answer our questions. From selecting the right roof to arranging to finance, to completing the project in a timely fashion, we could not be happier with the total interlock experience. We are highly satisfied with the result and are already looking forward to having Interlock install a new roof on our adjoining barn in the near future.

It just shows how professional and caring the company is

August 28, 2012

Dear Interlock Roofing, We want to say thanks for our beautiful roof, and the peace of mind knowing that we will never have to replace our roof again. The roof looks great and we just want to show it to everyone. The installers always kept our property very neat and clean. They worked long hours and were always very polite and professional. The supervisor came to our house to inspect their work and to see if we had any questions or concerns. It just shows how professional and caring the company is. We could not be more pleased with the way our rooflooks and matches our house. We love the slate look and how maintenance free it will be. Can’t wait for our first snowstorm and not worrying about cleaning the snow off the roof. The neighbors have told us how the roof looks great, and one neighbor could not believe that it was metal roofing. We are very satisfied and would recommend your company to others.

Sincerely. Ron and Laura R.

The Installation Crew Was Amazing

November 16, 2011

Dear Interlock, We are very pleased with the roofing system that we purchased from you. I have been involved in several construction projects, both commercial & residential and have never witnessed work done so quickly. The installation crew was amazing, they were fast, hard working and neat. it rained, and they did not stop working. During the install, people were stopping, just to watch, and to ask about the roof. They all were impressed. We still have people that stop and knock on the door to inquire about the roof. a man stopped earlier this week, interested in your roofing system… he should be contacting you. We have been through one winter with the new roof, needless to say… we have not needed to hire anyone to remove the snow from the roof as it slides off effortlessly. We have recommended your product to people, and should we need a new roof for any of our properties, we would call you again.

Regards, Landra S. L.

The roof is absolutely beautiful. It looks great and gives our home a new, distinguished look

Dear Interlock, I am writing to express my comments regarding the installation at the above address. First, we would like to thank Mike Baldassari for the professionalism he demonstrated during the initial meeting and follow-ups. His knowledge of the product and understanding of our concerns were related in a manner, that novices would understand. Next, the installers headed by Nikolay were knowledgeable and kept us apprised of the progress during the installation. Thirdly, I would like to thank Susan and Miranda for all their customer service support. Finally, the roof is absolutely beautiful. It looks great and gives our home a new, distinguished look. People stop and stare, to admire its’ appearance. Its’ appearance provides a stately, stunning look. This is our second and final roof at this home, which we expect to last for years, to the next Cassaro generation. I would recommend your company and product to anyone thinking about a long-lasting solution.

Again, thank you. Salvatore and Noreen Cassaro

You're not kidding! This is one fantastic roofing material

June 5, 2008

You’re not kidding! This is one fantastic roofing material. I have worked in the sheet metal trade before and understand the difficulties of working with metal. I would like to say your roofers are true craftsmen and artists. They worked 3 long days from early morning till evening I was so impressed by how fast it went up. I realize how difficult some parts of the roof were to do for them then others but your crew kept on going as if no problem was too big. They were very polite and all ways checked with me about things before starting and before they left to go home. I am already getting lots of compliments from our neighbors on how great the roof looks. I feel great knowing this will be the last roof I will ever need and know I can depend on it long into my retirement years. I had been thinking about replacing our roof with a standing seam roof for some time. But my wife & I have seen some that other contractors have installed and just didn’t think it would look right at our house. When we saw your ad in the paper we decided to check it out and were very glad we did. The sample you showed us for our house was perfect and our house now looks like it has a slate roof on it. I am very much satisfied and can’t wait for the first snowfall to see it just slide right off and not build up ice on the edge as it did with the shingles before. My wife and I thank you and would like to personally thank each and every one of the members of your crew on a job well done.

Sincerely, Joanne and Gary Goodnow

We live in a house that was built in 1886, and the new roof looks just like slate

April 22, 2004

We are very pleased with our new Interlock Roof!  We live in a house that was built in 1886, and the new roof looks just like slate. This was the perfect choice for our home, and we look forward to enjoying it for many years to come. We are very impressed with the quality of the materials and the workmanship of the roofing crew assigned to our home. The crew was outstanding, and we were very impressed with their punctuality and their roofing skills. The job site was kept neat and picked up throughout the process. Now that a week has passed, we still haven't found any nails or scraps in the grass around the base of the house. Please express our thanks again to the roofing crew for a job well done! We would highly recommend them and your company to anyone interested in a new roof. Feel free to give us out as a reference in the future.

Our new blue Interlock Roof is exceptional and the house looks absolutely great

April 22, 2004

There is no doubt about it. Our new blue Interlock Roof is exceptional, and the house looks absolutely great. We certainly were very pleased with your installers. Their professional workmanship and the efficiency with which they performed and completed the job were outstanding. They always took the time to remove the excess debris from around the house when they finished the day. It’s very refreshing to know that there are still companies that care enough to do the job right. As we are on a very busy road, we get to see people doing “double takes” to look at our roof. In fact, we gave a brochure to someone up the road from us, and you have since installed a new roof for that person. The overall effect is an excellent advertisement for Interlock! Thank you again for all your efforts; we are so very pleased.

Sincerely, Dan & Marlene Brodeur
