"Dan Keller and team do a very good job. They replace my roof as well as installed a solar panel system. They provide timely responses, show up on time and are priced reasonably. They are also very good at follow up on post installation matters."

"The overall process went very well. Michael came out to my condo several times. He's very professional and he dealt with my annoying property manager very well. I was impressed Michael was able to come out in the evening so i didn't have to take off from work to look at samples and discuss the project. He even left a window with my property manager for a few days to examine! All the visits and installers came on time which in my experience is never the case. In fact the installers came early! They were very quick, they did 9 windows in a little over 3 hours. I must say these windows are the best looking windows and cheapest out of all 5 other quotes i got. I opted for the brushed nickel hardware upgrade. They look slick! There was a period of time where communication was great but there was a reason for that and it's not common. Also when i was attaching blinds after the install, i noticed window coming through the top of one of the windows. I contacted Acorn and Michael came back out and fixed the issues. He then inspected all the windows inside and out and answered all my annoying questions. During his inspection he noticed one window was missing a clip to tilt it. He came again and installed that. I honestly didn't even notice the clip, so that shows he was really inspecting and put pride his the quality of his work. Overall i'm very pleased, the difference from my original 1987 single pane windows and these new ones is night and day!"

"We were recommended to go with Home Genius by our neighbor who was very happy with his roof installation from a few years back. What drew me to your company was the hospitality of the sales rep and his wonderful presentation. I believe we made the right decision, as our roof, unlike before, is a complete Owen's Corning system covered by a tremendous warranty. we no longer have to worry about leaks or issues because of our new beautiful roof and gutters. They even remove and reinstall your solar panels for you. Great company all around. friendly and helpful staff"

"They took down my 93-year-old slate roof (a dangerous and dirty job) and replaced it with asphalt in 10 hours. A good sized team with the right equipment. I watched all day and was impressed that no cut corners came into the job. They were very careful to do it right.The team of roofers were under a capable supervisor. They â flexedâ and put a little extra (material or labor) in, when something unexpected was discovered, or a slight customization to make the result better was called for. All the slate that came down was a huge mess of tiles, flakes and dust. They got that too. Iâ m going to use them again."

"We had our roof replaced in June. Carl's did an excellent job and the roof looks great! The workers were all great and they cleaned up the job perfect. Eric, the overseeing person at the job daily, was so knowledgeable. It was comforting knowing someone like him was there for the two days to visually overlook the job and inform us of what was going on. Our sales person, Will, was great as well. There were many calls and text that went back and forth before we decided to move forward and he answered all our questions. I highly recommend them."

"Sky Tech construction located in Ringwood New Jersey did an amazing job replacing our very old roof and replacing the gutters! Look no further and contact Sky Tech. The owner Dave was very professional, prompt and conscientious. Estimate of the work to be completed was right on target. Having two excellent staff workers in the company office was a real plus when asking a question or getting any updates.The team of roofers did a fantastic job replacing our roof. They did not take any shortcuts. When needed they replaced plywood and did a very complete restoration of roof. They were on time, polite and hard working. I was apprehensive about such a big job on my home. Any anxiety on my part was quickly put to rest. Sky Tech from start to finish made this big job a piece of cake. No worries were needed on my part. My yard/property looked better after Sky Tech finished all of their work then when they first began!! Thanks to Owner Dave and team of Bruce , Nina, Jenna, Manual and the rest of the roofing team I was so impressed and happy. Most important my boss [wife] was really impressed with the workmanship! A+++ rating"

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