"Signed a contract to replace half the roof for $5000 after assurance of no hidden cost and nominal cost for replacing some plywood. Due to rough weather the job was performed 3 weeks after signing. The roofer did not cover the roof with tarp and also spoke to Allstate who denied all my claims for damages. I was billed $1600 in addition to $5000. I have paid the $5000 but I deem the extra billing excessive. I was not informed of the cost for approval. I am willing to come to terms with the contractor and would like Angie’s list to review and work out a compromise. It also points to the level of service offered by the two contractors referred by your company. One bid for $2500 and precision roofing came in at $5000. I signed with Precision because of their assurances as an established company with a fixed cost. It has turned out not to be the case."

"Follow up to earlier review -JJP Contracting Jose and Brian are running a top tier business. I'm going to be totally honest with the people of Angi- We hired this team to perform a siding job and it originally didn't go well. They pulled down the pre-existing wood shingle siding that was rotted and installed new Siding on the home. When the siding first went up there was a defect that we all couldn't understand. We thought that it wasn't okay to leave it up but tried to see if the warmer weather would cause it to unbuckle. JJP stood by their words even months after the siding had been installed and came back to make the necessary fixes. I appreciate this more than the team knows because too often contractors are not true to what they say. This team is running an honest business that I can truthfully say that I trust. I look forward to discussing further projects with their group."

"I couldn’t be more impressed with Strong Hammer Contracting! From the moment I contacted them, their team was professional, prompt, and clearly experienced. They arrived right on schedule and handled my gutter cleaning with meticulous care—thoroughly clearing out debris and even checking for minor issues I wouldn't have noticed myself. What really stood out was their attention to detail and respect for my property—they left everything spotless, and my gutters have never flowed better. It’s such a relief knowing I can count on a company that takes real pride in their work. I’ll definitely be using their services again and recommending them to everyone I know!"

FAQs for natural slate roofing installation and replacement projects in Katonah, NY

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.
