"I can’t say enough about my experience with Benchmark Home Improvements! Lee and his son Ian were consummate professionals, exhibiting excellent communication and patience with us throughout the process of our stressful kitchen remodel. The timeline they gave us was “spot-on” and they were at our home every day until the job was completed perfectly and on schedule. They cleaned up thoroughly at the end of each day and pleasantly accommodated my two very curious dogs through the duration of our remodel. When I second guessed my choice of flooring, Lee and his wife went above and beyond on their own time to pick out some samples and set them aside at the store for me to look at. I went with one of their choices and I am so happy that I did as it looks amazing! This is truly a “family business” in the old-fashioned sense of the term, and that is hard to come by these days. They genuinely care about their craftsmanship and their clients, and they have a business based on integrity. I have to make special mention of Lee’s son, Ian, as he is mature beyond his years with skills to match it. I was beyond impressed with his expertise, execution and reliability. This young man exhibited a sense of principle and pride in his craft and was a pleasure to work with."

"FBI Contracting was the only firm willing to remove old decking, replace insulation in cathedral ceiling from above, install proper vent baffles, install metal shingles, custom form gutters. Frank and crew came every day until job was done. Compared to other roofers quoting only the shingle installation, FBI was very competitive. Cleanup was exceptional and the roof looks great! Multiple people walking or driving by have stopped and commented on the look of the roof."

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