"We are writing to express our sincere gratitude for the outstanding service we recently received. Ranch Roofing installed our roof back in 2012. Fast forward to 2025, when we had damage to our ridge vent, we called Ranch Roofing, and within 10 minutes had a call back from the owner, Bob. He said he would have it looked at and fixed, but to our surprise, in a matter of a few days, he sent his crew, who ripped the entire ridge vent off and replaced it free of charge. We cannot say enough positive things about Bob, his Crew, and this Company. Thank you Bob- Your quick response and generosity are much appreciated! Sincerely, Maryann and Randy D. "

Established in 1976, All Under One Roof has the experience and expertise to get the job done right the first time. Our skilled professionals use only the finest tools and materials for your residential or commercial project. We guarantee our work and your satisfaction.

"Overall it went great. John was down quickly after I first contacted him. He came out in person to give me information and confirm the online measurements. Between meeting him, reading the reviews online, and the impeccable warranty I felt very comfortable choosing him (the price was in the middle of the other quotes I got). The whole process took 3 real long days. Obviously it is loud and disruptive while they are working... but you only need a new roof once. I would suggest not parking in your driveway as there are a lot of people and trucks. At the end they cleaned up very nicely. They are a legit roofing company so they pull permits. Overall I am quite please for the job, cost, time etc."

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.
