"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."

"I would not recommend them. Initially it appeared they did a good job on my rubber roof, so I hired them again for full gutters, which they subcontracted out. Within the year I had a large leak develop behind their new gutter. They acknowledged the problem but it took months, and constant badgering by email and phone, to get them to come back and fix the problem. They tried a temporary fix with sealer, which failed in weeks, and then it took weeks longer to get them to come back and install a fascia apron. The next year, my rubber roof leaked where they had flashed it. Again it took months to get them to come back and look at it, with constant badgering. When they came back they applied a copious amount of sealer and told me that I had a rot problem with a wooden railing that I would need a carpenter for, and that they would send me photographs and suggestions for repair. They never replied after that, and the leak continued despite their sealing attempt. I finally gave up and found a new roofer, who tells me that they did an inferior job in the first place, and the repair is costing me thousands of dollars."

"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 Westborough, 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.
