"Roof was 25 years old and was due for replacement. I also had old LP fiberboard siding that needed replacing in some sections mainly the chimneys. The rest was ok and I couldn't see spending the money to replace it all. George Keller did a terrific job on the roof and worked with me to match the LP siding using James Hardie siding. Carl the estimator took his time gave me a detailed estimate with pictures showing all the sections of siding that would be replaced. George Keller had done other houses in our neighborhood and one neighbor, an architect, used them, so that speaks to their reputation. I would highly recommend them. They are very efficient and neat and will finish your job in a day or two."

"Mike was very good at explaining the products he had to offer and going over the installation process. The head installer Joe and his assistant Israel were both top notch. They were polite, neat and most importantly to me, very professional. They introduced themselves and then got right to work. At the end of the job, Joe and I looked over the work together and then he refreshed my memory on the operation of the windows (tilting, screen removal). I was very pleased with the quality of their work and the product itself. I would definitely recommend Acorn Home Improvements."

"Very dependable and professional work. They were able to identify why we were having problems with roof, leaky window, gutters, etc and addressed/fixed the problem. Definitely had more confidence in their work than with any other contractor we have hired over the past 15 years in our house."

"They did a good job, their pricing was very competitive and they were right on time, they came when they had to come, they did some extra but did not charge me for it, and they put the fence in and I had no problems with the location, they are very knowledgeable and the clean up was excellent, there was no debris left after their work, and they walked me though the project to make sure that everything was done to my satisfaction. They also do other works, so I was considering hiring them again in the future for my roofing. My neighbor saw my fence and they going to hire Carl again for their fence as well."

"My wife and I were very pleased with Tom from beginning to end of the project. We reached out to Tom thru the Velux Skylight website. Tom responded immediately and came over on a Sunday to look at our damage. He emailed the quote in a few days and we agreed to his terms. Tom and his helper replaced and repaired during very cold & windy weather. They did a fantastic and professional job! The skylight and roofing were installed perfectly and they cleaned up every scrap of debris from inside and outside our house. We have used numerous contractors over the 30-years we lived in our home. We've frequently been disappointed and rarely used them twice. We are so pleased with Tom that we will be contracting him to do a new deck for us in the summer. We would highly recommend him!"

"The inspector came by and walked the roof and told us that we did not have any leaks and that the roof was in great condition. Because of the intense heavy rain we had seen some slight dampness in the attic but he said that was normal given the heavy rainfall. We thought he was very sincere and professional."

FAQs for natural slate roofing installation and replacement projects in Raritan, NJ

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.
