Interlock® Aluminum Roofing — all-climates performance specs for South Dennis, Massachusetts
| Spec / Rating | Climate / Risk Factor + What It Solves |
|---|---|
| Wind resistance: 120+ mph (193+ kph) | Extreme wind, hurricanes, storm uplift: full interlocking attachment helps prevent blow-offs, edge lifting, and panel loss in high-gust events. |
| Fire rating: Class A (with proper assembly) | Wildfire, embers, radiant heat, chimney sparks: non-combustible roof assembly provides the highest residential fire protection rating. |
| Hail resistance: UL 2218 Class 4 | Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes. |
| Snow & ice performance: interlocking, shedding profile | Heavy snow, freeze-thaw, ice dams: smooth aluminum sheds snow efficiently and the interlocking design helps block water intrusion when melt-refreeze cycles occur. (Final snow-load capacity depends on roof structure and local code.) |
| Corrosion resistance: aluminum (won’t rust) | Salt air, coastal humidity, wet climates: aluminum naturally resists rust and corrosion, reducing long-term failure risk in marine or high-moisture environments. |
| Heat / UV durability: baked-on coating system | High heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation. |
| Moss / algae resistance: smooth coated surface | Wet shade, organic growth: low-porosity metal surface gives moss/algae less to grip, reducing staining and maintenance. |
| Material: heavy-gauge aluminum roof profiles (Slate / Shake / Shingle / Tile / Standing Seam) | All-season structural stability: lightweight, dent-resistant metal system stays stable through large hot-cold swings and severe weather. |
| Expected lifespan: 50+ years | Long-term durability across climates: avoids re-roof cycles typical of shorter-life materials, even in high-stress environments. |
| Warranty: Lifetime-Limited, non-prorated + 50-year transferable | Lifetime protection + resale value: guarantees long-term material confidence and transfers to future owners. |

What our customers are saying:
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
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
Located in Dorchester, I chose Interlock Metal Roofing - New England; their Metal Roofing exceeded expectations with clear communication, professional installation, respectful crews, daily cleanup, and a gorgeous, durable roof that’s the talk of the neighborhood—highly recommended.
I've had an Interlock metal roof on my house and garden shed for two years now. It's absolutely gorgeous. Everyone thinks it's a slate roof! I've had no problems with it. The installation was amazing! A crew of 11 showed up early in the morning and were almost completely done in one day on both buildings. They were so professional. I highly recommend Interlock for both their high quality product and their great people.
I just had a brand new Dark Grey Metal Roof by INTERLOCK installed. I found everyone that I dealt with from Jonathan Brown in sales and Jennifer Simons in the office and to the crew that did an excellent job ( they were very hard workers)! I am pleased with the outcome of the roof. It looks wonderful, I would highly recommend interlock to anyone who Is looking for a quality roof and excellent and professional installation.
The work was both of excellent quality and done on time. The worksite was left exceptionally clean. I would recommend Interlock Roofing to anyone looking for a great product and great service.

Just a note about the roof we installed in March of 2003. The first thing that we have to say is that the roof looks wonderful; it’s the best one on the street. A neighbor two houses down the street had a new asphalt roof installed shortly after we had our Interlock Roof installed. The neighbor across the street remarked that our roof looked a lot better than the neighbor's. We have had quite a few neighbors stop and ask about the roof and remark how good it looks. Having the chimney flashed with a solid flashing (instead of step flashing) and the ducts matching the roof really makes the roof look finished off. Also, having them put vents on the back which match the roof looks finished off, so they are not noticeable. As far as the workmen and the quality of workmanship, we feel that it was done very professionally. We asked that they not start working until 8:00 am, and they waited until 8:30 am to start. They kept the grounds very clean even when they were stripping the roof. They hung tarps so nothing could or would damage either the house or any plants which are around the house. They were very friendly and courteous. In closing, we are very pleased with the roof and the professionalism of the workers.
Communication after the job was a bit lacking, when we had a couple of questions about signage left out front. Everything leading up to the project was perfect! We love the look and quality of our new roof. Your process was exceptional, and your staff great to deal with. The job was completed a month ahead of schedule and took half the time that we were expecting. We hope to never have to use the warranty, but should we have to, I’m confident that we will be taken care of. Great job!
My experience with this company was so easy. First I met with my salesman Johnathan Brown. He was so wonderful explaining everything, very friendly . Loved working with him. The workers were very professional ,did a great job and left no mess. Customer service was very easy to ask any questions. Love my new roof and the company I chose to do it
They have a wonderful product and are incredibly knowledgeable. I have nothing to suggest. They are an amazing company. They did an excellent job and my house feels great with the roof and what it has done for the temperatures.
I would recommend the Interlock Roofing System to anybody, my friends and neighbors were impressed by how nice my roof looks. The men that installed the roof were very respectful and courteous. I was shocked by how quickly they were able to install the Interlock Roofing System. Not only do I have a beautiful roof now, I have the " data-wpil-keyword-link="linked">warranty and you can transfer it to a new owner if I ever sell the house.
