"I've decided to do the work myself with some help from my son. The price was way more than I thought it would be and I could use some natural materials and spend less money. The representative from the company was professional and knew his product but, over $ 14,000 for a tub/shower replacement was way more than I wanted to spend."

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