"I had an excellent experience with RB Farina's work replacing old wooden gutters and old wooden fascia and soffits with new aluminum gutters and PVC soffit, fascia, and molding on my small house. I must have caught things at a good time, in late winter, because it was just 8 days between my posting my job description on Angies List, and the dumpster leaving my driveway after the work was completed. The original bid was completed at the original price, with some extras (significant touchup painting, and a quick repair on the 2nd story shutter of my neighbor who was kind enough to let us use her yard for ladders) done with no upcharge. I did not seek multiple bids so I cannot say whether the price was high or low; I counted on the fact that the bidder could expect competition. Weather was good for working and we had no ugly surprises from my very old house, so the work went pretty smoothly. I had the pleasant experience of finding that for each of the materials and methods that I either knew about or researched, in every case the Farina team was using top quality. They are good about communication: calls to the office, or by cellphone to the estimator, always were answered live or resulted in callback in a few minutes. The onsite crew was polite, responsive, and very professional. (They also looked like they were enjoying their work, which is always a good sign). The office was very proactive: the written bid arrived quickly, and every check I wrote resulted in an emailed invoice/receipt within a couple hours. For this they are using a platform called HouseCallPro, which automates the workflow considerably. (Why shouldn't buying this kind of services get as good a workflow and email trail as, say, ordering a toaster on the Internet?) . I worked hard to make the jobsite easy to work in (moved stuff away from the house, took down my window screens before they came, ran a wire out the window to provide 20amp electric power, provided a map of where the electricity and water are on outside of house, provided outside access to a bathroom), and the crew was appreciative. Day 1 was demolition, Day 2 was carpentry, Day 3 and 4 were gutter hanging, sealing, and painting. Once they got the gutters up and sealed, they ran the hose into the gutter to check for leaks and flow before they did their final cleanup and left. After watching how they did this work and what materials they used, I have pretty high confidence that their work will last a long time,. I plan to sign up for their annual gutter/roof/chimney maintenance program so that my gutters get cleaned and somebody I trust looks at my roof."

"The attention to the customer, the explanation of what the work involves and the work plan, and the response to customer followup questions, is excellent. I cannot rate the work quality, since I know nothing about assessing roofing repairs, which also impacts any judgment about value for money as related to quality. But, this company is *very* expensive as compared to others in competition. Providers who charge a lot always claim it is due to superior quality, that is, the quality justifies the price, but laypeople cannot tell if that is accurate and justified or not. For us, this company was too expensive to hire for the remaining work."

"As a facilities manager I have relied on O.T.I. for the last several years. They have replaced several roofs on some of our properties. Our roof projects have had a price range of $50,000 to $150,000. They have also been our general contract for several other projects inwhich they have always come through for us. In most cases in a pinch with tight timelines."

"The roof was in line with everybody else's price. It may have been a little bit more expensive but we liked dealing with the guy. They were super clean, they knew we had pets so they were aware of  the nails and such so the ones that got away were like about 3 and they were quick. They were really professional and I had a really god experience with them."

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