Interlock Metal Roofing did an excellent job. From sales to working crew they completed job quickly and professionally. The weather and roads were not good. But they performed admirably. I have nothing but a good opinion of this company and their employees.

Northwood, New Hampshire—a town steeped in history and natural beauty—a homeowner sought a roofing solution that would stand the test of time.

Enter Interlock Metal Roofing, renowned for its high-quality products and exceptional craftsmanship in installation. The homeowner’s experience reflects the company’s unwavering commitment to professionalism at every stage—from the initial, pressure-free sales consultation to the diligent efforts of the installation crew. This commitment instills confidence in the homeowner and ensures a smooth, stress-free process.
The Deep Charcoal Interlock Metal Slate Roofing System not only enhances the home’s aesthetic appeal but also offers a lifetime warranty, energy efficiency, and exceptional durability. Its 4-way interlocking design ensures high-wind resistance, and its compatibility with solar panels underscores its modern functionality, making you feel like you’re investing in the future of your home.
As the homeowner aptly stated, “You get what you pay for with Interlock. That being the best-looking, functional roof in the business!” This level of satisfaction is a testament to the quality and reliability of Interlock Metal Roofing, providing you with the reassurance you need when making such an essential investment in your home.
In a community like Northwood, where historical charm meets the demands of New England weather, choosing Interlock Metal Roofing is more than a home improvement—it’s a lasting investment in quality and peace of mind.
Here in Northwood, NH, our winters are no joke — heavy snow, ice buildup, and deep freezes are standard. Traditional shingles often crack or shed granules, leading to costly repairs. That’s why we recommend our Interlock aluminum roofing system, designed with a 4-way interlocking mechanism to withstand snow loads, ice dams, and high winds — without ever needing replacement. And yes, it comes with a lifetime warranty, giving you the peace of mind that your home is protected.
Ice dams are a common issue in New England, particularly in hilly areas like Northwood, where roof angles vary significantly. The key is proper ventilation and roofing materials that shed snow easily. Our metal roofing naturally sheds snow and doesn’t absorb moisture like asphalt, helping to prevent ice buildup. We also inspect attic airflow and recommend solutions to optimize your system.
That’s a myth we love to bust. Interlock roofs are installed over solid sheathing, underlayment, and often your existing roof — making them just as quiet as asphalt, if not quieter. Rainstorms in Northwood might be loud, but your roof won’t be.
No. Our roofs are made of high-grade aluminum, which doesn’t rust — unlike steel. With Northwood’s humid summers and lake-effect storms, choosing an aluminum roofing system means long-term peace of mind, no rust streaks, and virtually no maintenance.
In most cases, no. Our Interlock system can be installed directly over a single layer of shingles, saving time, labor, and landfill waste. We inspect every home individually, but 90% of Northwood homeowners can skip the tear-off altogether.
Yes! Our roofs are coated with advanced reflective pigments that reduce heat absorption and reflect sunlight. Northwood summers can get hot and humid, but your attic — and your energy bills — will feel the difference. Many homeowners report a 25% or greater drop in cooling costs.
Northwood sees its fair share of windstorms and microbursts. Interlock’s 4-way interlocking panels are tested to withstand winds up to 120 mph, making them ideal for homes exposed to tree cover, open fields, or hills. With Interlock, you can feel secure and protected, no matter the weather.
Yes — Interlock Metal Roofing is solar-ready. Unlike asphalt, which often requires replacement before or after a solar installation, our system is designed to last 50+ years, ensuring your solar investment is protected and future-proofed.
When you consider the zero future replacements, energy savings, and increased home value, Interlock becomes the more cost-effective option over time. Northwood homeowners love that they “Never Re-Roof Again.” You’re not just buying a roof — you’re buying peace of mind for life, making it a smart and economical choice.
We’ve installed thousands of roofs across New Hampshire, and we understand the specific needs of local homes. If you want a roofing system built to last, no matter the weather, Interlock is here to help.
Bedford, a town where tradition meets innovation, is in the heart of southern New Hampshire, nestled among rolling hills and vibrant woodlands. Just under an hour’s drive from the Atlantic coastline and within reach of the majestic White Mountains, Bedford offers a unique blend of natural beauty and suburban charm. Its distinctive features, such as the Pulpit Rock Conservation Area, make it a town worth exploring.
One of Bedford’s hidden gems is the Pulpit Rock Conservation Area, a haven for hikers and nature enthusiasts. This area boasts extensive trails leading to the iconic Pulpit Rock, offering breathtaking views, especially during the fall foliage.
Standing amidst this picturesque setting is a 1978-built Colonial home that recently underwent a stunning rejuvenation. The homeowners, recognizing the importance of durability and aesthetic appeal, chose the Musket Grey Interlock Slate Shingle Metal Roofing System. This choice was based on Interlock’s lifetime warranty, energy efficiency, and distinctive curb appeal. The 4-way interlocking design ensures high wind resistance, making it perfect for New England’s varied weather.
Mary, the homeowner, shared her experience:
“Interlock Roofing just completed roofing our home. Looks great! Experience with Jonathan Jennifer Gallo and his workers couldn’t have been better. Wished we had done this sooner.”
This transformation enhances the home’s value and aligns with Bedford’s ethos of blending historical charm with modern resilience. As the community evolves, stories like Mary’s underscore the town’s commitment to quality and enduring beauty.
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 they 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!

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!

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!

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!

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.

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.

We loved the roof so much after they did our house that we called them to come back and roof the barn too. It’s a beautiful roof and gets lots of comments, and the 50-year warranty is great! The install crew works hard and leaves the yard spotless.

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.

Hi Dave!
We are very, very pleased with Tomas. His workmanship, attention to detail and professionalism exceeded our expectations.
If this is an indication of quality from Interlock, I’d be glad to endorse your company. We’ve had people drive by and comment on the work.
When it is done, it’ll be so spectacular that it’ll stop traffic (we’ve had some people who stop to take photos already).
We only hope the weather improves, and we look forward to having Tomas do the rest of the church. He is exceptional!!!!
Thank you!
