"The crew at James & Whitney co were extremely friendly, courteous and went out of their way to make sure that we were happy with our new roof. The job was done fast and is of wonderful quality. Beyond that, this is a company that truly stands behind their work, as they have reached out to me several times in the past few months to ask how the roof is holding up. I truly couldn’t recommend James & Whitney highly enough to anyone who needs work done on their roof."

"Marquis Roofing did a fantastic job on our roof. The job was completed in one day. Tom Marquis's crew was professional, highly qualified and courteous. Once completed, the job site was completely cleaned of any building material and nails. I would absolutely hire Marquis Roofing again should I ever need another roof job done."

"We're so happy that we chose Benchmark Home Improvements for our kitchen renovation. Lee did a great job with the design. He was very responsive and had great ideas. Ian and Lee did a great job with demo of our old kitchen and installation of our beautiful new cabinets. They kept everything clean and organized and were very respectful of our house and family, even considering social distancing, etc. during this crazy time. When the job was done we had a problem installing our refrigerator they were quick to return and creatively resolve the issue. We highly recommend Ian and Lee at Benchmark Home Improvements to anyone looking for a great kitchen renovation."

"I needed a small repair, due to a less than stellar original install (unknown contractor) when the home was built. Paragon came out in a timely manner and repaired the roof quickly and professionally. I plan to use them this summer when I contract for the roof replacement. Very satisfied with their work."

FAQs for natural slate roofing installation and replacement projects in Somersworth, NH

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.
