"Craig is awesome. His price was very reasonable, his crew came when they were expected, got the job done, and took great care. Craig has followed up several times to ensure everything is still good and I absolutely LOVE the copper. The slate looks amazing. Thank you so much!"

"I HIGHLY recommend Pro Warrior! I've hired them for many jobs already as they are responsive, affordable, and proactive. I had them replace my roof and siding - I am obsessed with the results to say the least. I hired them back to complete a finished basement. Pro Warrior is the absolute best around."

"Bob Dyer ( D"s Homeworks) was friendly, honest and a pleasure to deal with. His crew was respectful of our house and for the two days that they were here. They made sure that everything cleaned up before leaving for the day. They replaced the windows and double patio doors on our home. You always worry when you hire a contractor and wonder if the job will be completed on time and without any additional cost. The work completed went beyond expectations and no increased cost. It's nice to know there are still honest, skilled and fairly priced businesses like D"s Homeworks out there. Thanks to Bob and his fantastic crew."

"Victor came to inspect the leak problem we have. We have an intermittent leak, but I could not find the source of the problem. Victor and I went into the attic and he was able to find where the water was getting in. Then we went outside, and Victor went onto the roof. As it turns out, wind damage to some of the vinyl siding is the source of the leak, fortunately not the roof. So, I cannot attest to the quality of Master's work, but if the others at Master Roofers are like Victor, you will be in good hands."

"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."

"I got an estimate very quickly on the repair and a general assessment of the state of the roof. Mr B's was only one of two roofing contractors that I called that would even do a repair, and Mr B's was the more prompt and better estimate. While very busy, he was able to fit me in sooner than originally estimated, and did a great job. I'm very happy and will call them again when more work is needed."

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