"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."

"Pellegrino Construction did an excellent job on our roof.  While it has only been a few weeks since completion, we are very pleased with the work.  Mike P. was very responsive and professional throughout and answered all of our many questions. We would definitely recommend them and use them again. 
We first had Mike come and assess whether we could repair a leak.  He indicated he could likely repair it for a reasonable cost, although there was no guaranty the fix would work,  He was the only roofer we saw who was wiling to try to fix the leak before replacing the roof.  He also explained why we would soon need a new roof and let us now that we could likely wait a year or two, with minimal risk (this was the consensus among the roofers we spoke to).   Among the roofers we spoke to, he did not oversell the need for a new roof and provided an excellent explanation of the various issues.  We decided to replace the roof now to be sure to fix the leak and not worry about a problem in the next year or two.  Mike was flexible on using the materials we desired (within the constraints of the mfr. warranty) and on timing.  Compared to the other roofers we spoke to, Mike's pricing was a positive as well. 
His team also cleaned up well and pointed out how they accidentally damaged an end cap on our deck.  Mike immediately repaired the damaged end cap and has been responsive after the  job as well in answering a question or two of mine.

"Great job. I thought I needed to replace my deck--the wood looked moldy and pitted. But, after Nathan finished, it looked fantastic. A coat of stain should be all I need now. Before washing the roof, Nathan took photos of it and alerted me to potential issues I might see in a few years--he's not selling roofing replacement so this was strictly a friendly heads up. I hired A1 because they perform low power roof washing, which avoids any potential damage to the tiles. I would recommend A1 without any hesitation."

"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 Dunbarton, 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.
