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."

We are a full service roofing company. Our focus is in residential and commercial roofing, We work with many manufacturers for all types of roofing from metal to asphalt shingles to all types of low slope roofing membranes. Additional phone - (508) 299-7663.

"Called On top roofing for an estimate, it took several weeks to get back to us, got the estimate and agreed to have the work done. A few guy showed up one day and started working, we were not notified they were coming to work,good thing we were here that day. They did the job and left without ever communicating with us about the work. We did a walk around and discovered that some of the work was not completed. So called the company back and the owner came out to look at the job, he said it would be about another $100. To complete. We were not happy because this was supposed to be in the estimate we agreed on. The workers show up again unannounced and did the job. We then received a bill for $200. More, again this was not what was agreed upon when talking to owner. We were hoping to form a relationship with this company for future work, but that's not going to happen, there was no communication and even with a written contract they will somehow charge you more than agreed on."

FAQs for natural slate roofing installation and replacement projects in Harvard, 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.
