At Roofer's Edge & Siding, Inc. we have earned a reputation of honesty and professionalism. Whether it's a simple roof repair or a full replacement, we make every effort to ensure our workmanship and customer service is at the high level our customers have come to expect. Our areas of expertise include roofing, siding, windows, doors, insulation, skylights, gutters and leaf guards. We stand behind our workmanship and materials with guarantees that make our customers feel confident in their new investment. With a general contractor license, we are one of the few full-service companies in the area that you can count on for nearly all your home-improvement needs. We know that our reputation is on the line with every job that we do. We have outstanding satisfactory rating with our customers and we are very proud of that.

"I had a terrible experience with Roofers Edges & Siding Inc. We decided to replace the roof for solar system, and hired them to do the job. Remember: you are not hiring Kevin but his crew!!! The communication was extremely poor. At first, despite Kevin agreeing to use an ice shield for the front of my house, his crew was unaware of this requirement. I saw they are using the wrong material, and I had to contact Kevin at the installation day to ensure they were doing the job correctly. It was frustrating that the crew couldn't understand English, and Kevin himself never showed up at my house after the initial estimate. To make matters worse, the roof replacement resulted in a severe water leak problem between my chimney and roof. I asked them to fix it, but they failed once and never showed up again even though they provided an one-year warranty. At very beginning, I fully trusted them, and didn't check regularly, eventually I found the leaking problem persisted several months after the replacement the roof! Despite numerous attempts to contact Kevin, he consistently failed to respond to my calls and texts. Instead, he tried to blame the issue on a chimney problem, and told me they can do a water test, but that never happens. I eventually had to hire a new company to look into it, and they found out that the FLASHING was NOT INSTALLED CORRECTLY!!! and I can see the sky from my attic. I had to pay extra money to redo the flashing job, and Roofers Edges & Siding already lost my trust. The lack of professionalism continued when they claimed to have applied for a permit for the job, and I trusted them. However, several months later, I found out that there was no record of the application with the town. When I contacted them, they said the issue is an incorrect address, how un-professional they are! Overall, I would not recommend Roofers Edges & Siding Inc to anyone. Their poor communication, lack of professionalism, and shoddy workmanship were unacceptable. If you're looking for a reliable and trustworthy roofer, I suggest you look elsewhere."

"Very disappointed. We asked for triple pane windows, and someone on their end ordered double pane. Luckily we noticed day of installation, and they had to re-order the proper ones we signed for. Finally the group of installers who came did a horrible job. Trash, insulation, and broken glass on our front lawn. Horribly cut wood trim that we had to redo ourselves. Poor sealing that we need to redo. Our hopper window was misaligned and couldn't close. The hinge arm on our casement window has detached from the channel. Communication is spotty from them, and sometimes we don't get an answer by call or text until we message repeatedly. It took over a year to have our project done from contract signing to end, and there are still issues cropping up. Out of the dozen of contractors we've hired the past year and a half, they have been the most disappointing and for what we paid, the quality of work was truly disappointing."

"Home repair gone wrong… Do NOT use Connell for any home repairs! If you do make that mistake, do NOT hand over your final payment until ALL work has been completed to your satisfaction. A large dead tree uprooted and fell on the corner of my house during a rainstorm in December 2023. It caused damage to my siding, roof and chimney. A neighbor came to look at the damage and suggested a company to repair the roof and siding. It was Connell Roofing. I had not used them previously and would NEVER use them again for any work! They told me it would take 4-5 days to complete the work. They brought in a dumpster and began setting up their equipment in June 2024. Things seemed to be good. I was working remotely so could monitor the progress. On day 1, I had a woman contractor ask if she could use my toilet. Then the next day the same thing. Then a man asked to use my toilet. I decided to call the head company and they told me that workers should be going to the bathroom when they leave my house for their lunch break. In the 7 days that they worked on my house, they NEVER left for lunch. They were there at 7:00 am and left around 7:00-30 pm. When I went downstairs to my kitchen, I several times witnessed male workers walking towards the woods on the side and rear of my property looking over their shoulders. Then I saw them at least twice standing in the woods on my property about 25-50 feet from my lawn urinating. I reported that to Connell. You would think that if a company was going to spend 5 days working at your house they would bring a port-o-potty. I can only imagine them defecating in my woods had I not been working from home. Who knows, they may have done that while I was not looking. I prefer NOT to think about it. They played a boom box super loud! Even with my windows closed and A/C on, it was noisy to work in my office. One of my neighbors actually moved out of their house on the 3rd day and did not return until after the work was finished. The workers worked too long a day. I am used to getting things done after work in the evening in my yard like mowing and gardening, but that was all but impossible with the crew working until 7:30 pm each night. To replace my roof, they needed to remove all the old nails. Although they used a tarp to catch them as they were removed, and a magnetic equipment on wheels to gather them each night, I spent the next several months picking up nails all over my yard which must have numbers at least 200! I have a 9 year old daughter who often runs in the grass barefoot. I could only imagine the hospital visit if and bill if she stepped on one and it went through her heel. I have a small mudroom in which I built a beautiful wooden bench that I stained. When the men came in to reside that area (it was previously sided by the former owner), I watched one man feel how smooth the bench surface was. The workers then proceeded to stand on the bench the next 2 days working without a blanket and scuffed the heck out of the surface! I had to sand it several times and recoat it, but the dents and scrapes will remain. All of my gutters and downspouts needed to be replaced. It sounds easy to put 2 pieces of gutter pipes together, but if your workers are not properly trained, and there is a lack of supervision and inspection by Connell, problems will arise. The day the gutters were finished we had a heavy downpour. I went outside to see how the new gutters held up. The one by the garage was gushing water out of its sides for who knows why. When I looked a little closer I could see that the pipes were connected backwards, so the top piece was outside the bottom piece. Had that gutters been inspected, the problem would have been noticed before it rained. Although the workers used a tarp to shield my front door while removing the old siding, they did not protect when they put the new siding up. I had scuffs all over my black door so it needed to be repainted. When Connell sent a painter, he was not a professional. He clearly missed spots with the brush, and you could see that he did not have enough paint on his roller when he rolled the paint on. I called Connell several times then and then months later to get it repainted again. A few days after he painted it, the paint started shipping off. I had not touched it, not had there been a storm, it just was not painted right. 14 months of excuses and my door remains unfinished. I wanted to delay a portion of my final payment at the end of work in June 2024 until my door had been repainted to my satisfaction, but was heavily pressured to pay every penny then, and was guaranteed that the repair would be made to my satisfaction and soon. The workers in the head office talk a good game and are great at making excuses for their workers’ work but are slow/unresponsive to fix problems. Final opinion: DO NOT USE CONNELL FOR ANY REPAIR WORK."

"I hired Long Roofing Products to replace my roof. From the beginning the sales man lied to me, telling me that they could take off my Gutter Helmets and put them back on correctly. This was lie #1. They have null and voided the warranty of my gutter helmets, because they were not supposed to touch them and according to Gutter Helmets all the roofers know this. lie #2 there were missing pieces on the ends of my gutter helmets to prevent the birds from getting into the gutters. The salesman told me they would order the piece from Gutter Helmets and replace it. This was never done. I have contacted them several times and they continue to tell me they will fix it and they never do. I would NEVER recommend them, I would only tell you NOT to use them. They talk a big game but never follow thru with their promise's."

"NMTI (who we hired as Tru Blue Construction Inc) were superlative. Juan and Ramon were excellent communicators, answering all of our questions in a timely, professional, and endlessly patient fashion. Our project was a big one - our self-managed condo building had a severely leaky roof that needed a full replacement, including redoing a roof deck - and I imagine we were not the easiest clients since we had tons of questions and a lot of "cooks in the kitchen" with different owners and condo trustees weighing in. Juan and Ramon took it all in stride and were incredibly helpful for me in my role as project coordinator. Their team was clean, efficient, effective, respectful, and friendly. They worked both quickly and thoroughly, and were good to always keep me updated as the scope of the work evolved as we found new (but not unexpected or spurious) issues during the demo/rebuild process. Juan was an excellent advocate for us and our project when the city was slow to approve permits/send inspectors. It was a big and intimidating job for us as homeowners, and NMTI/Tru Blue made it feel much less overwhelming. We're thrilled with our new roof and deck and so pleased with the experience of working with Juan, Ramon, et al."

FAQs for natural slate roofing installation and replacement projects in Millis, MA

A slate roof features thin tiles of natural stone installed over a solid deck and underlayment. Formed under intense heat and pressure, slate is exceptionally durable and delivers a distinctive, high-end look. Because the material weighs far more than asphalt, most homes need added structural support before installation. 

While upfront costs are higher and routine inspections are a must, many homeowners choose slate for its unmatched longevity and curb appeal.

Slate stands out for its 50- to 200-year life span, low maintenance, and classic aesthetic. It’s fire-resistant, energy-efficient, and often boosts resale value. 

On the flip side, slate runs far more per square foot than asphalt, weighs up to four times as much, and demands a contractor who specializes in the material. Tiles can crack on impact, and repairs cost more because the work is slow and precise. If your budget and structure can handle it, slate delivers top-tier performance for generations.

Natural and synthetic slate aim for a premium, stone-like appearance, whereas asphalt focuses on affordability. Real slate runs $10 to $30 per square foot installed and lasts up to 200 years; synthetic slate costs $10 to $15 and tops out at 50 to 100 years. 

Standard asphalt averages $3 to $8 per square foot and needs replacement every 20 to 30 years. If you want the slate look without the full price tag—or extra roof weight—synthetic is a solid middle ground.

With routine inspections and prompt repairs, a natural slate roof can last well beyond 100 years; some hard-slate installations reach the 200-year mark. Soft slate falls in the 50- to 125-year range, and synthetic products last 50 to 100 years. 

Remember, flashing, fasteners, and the underlying structure may need attention sooner than the stone itself. Severe hail or fallen limbs can also shorten life span, so schedule periodic checkups with a slate-qualified roofer.

If you plan to stay in your home long term—or want a standout selling point—slate delivers strong value. Although installation costs are high, owners often recoup 60% to 70% at resale and enjoy lower replacement cycles than asphalt. The stone’s durability, energy efficiency, and timeless curb appeal also appeal to eco-conscious buyers because fewer roofs end up in landfills. Just be sure your framing can handle the weight and that you budget for occasional specialty repairs.

Skip the DIY climb if you have a slate roof. Slate may be tough against the weather, but a single misplaced step can crack a tile and create a leak path. The surface also turns slick when wet, upping the risk of injury. Professional crews use staging and hook ladders that spread weight across multiple slates, protecting both the roof and the worker. To inspect or repair slate, call a roofer who specializes in the material.
