"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!"

"They physically got on the very steep roof and inspected the roof before providing estimate. Took photos to illustrate issues with roof. Ultra pro provided a fair estimate. Friendly to work with. Completed the project within 2 days (big roof) and did an excellent job of installing the new asphalt shingles. They also replaced many covers and the vent fan. They also report using 6 nails per shingle to properly secure shingles to roof. My only criticism is they could have used more tarps to make clean up easier and more thorough for themselves. Nevertheless, a weekend DIY warrior who recommends these guys."

"Connor, our sales rep, was extremely knowledgeable, helpful in explaining the process of getting a new roof, and extremely thorough with his inspection. As for the installation, the project manager, Mike, was an extreme pleasure to work with, as he was persistent in making sure the crew and dumpster arrived as scheduled. I was absolutely amazed at how efficient and timely the crew was throughout the whole process of the install, and they made sure that if anyone was home, they were mindful when working of people coming in and out of the house. I would highly recommend this company to anyone looking to get new gutters, windows, siding, or roof! The process was super easy, the price was manageable, and they offer great financing as well in order to work within your monthly budget, especially for the quality of the roof."

"Working with David DelPizzo and Johnny we decided to replace the entire section of fence. Johnny explained that the new fence would not match the existing fence exactly but it would be close. We agreed on the price and proceeded with the project. This is where I put pressure on Johnny to get the work done ASAP so as to not hold up the hardscape contractor. Carl's came through for me again! Not only did they rearrange their schedule to make this happen, the quality of the fence, hinges and latch is so much better than the existing that now I am considering replacing the entire fence... I have been working with Carl's for two years now and they have not disappointed me once..."

"I recently had my roof replaced by Bora Construction Group, and I couldn't be happier with the results. Their team was professional, friendly, and efficient from start to finish. They were able to complete the job within the given timeframe and left my property spotless when they were done. I would highly recommend Bora Construction Group to anyone in need of roofing, siding, or gutter services."

"Dave and his crew were the consummate professionals. He showed when he said he would and provided contract, estimate and work date on the same day. His team came on a 100 degree day and finished the entire project in one day. He is also guaranteed & insured so it took the worry off of me. I had no idea how much of a mess a new roof creates on your property - not to mention the 100's of nails scattered everywhere - and every bit was removed (never found even ONE rogue nail) by the end of the day. Dave and I had also discussed an item to be done that his team did not complete. When I called to discuss with him, he agreed and sent his team out the next day to complete. I so respected his integrity, professionalism and courteous staff. His pricing was also completely fair. I never felt taken advantage of. Would highly recommend & trust him to do any roofing, decking or gutter jobs. I promise you won't be disappointed! Thanks again Dave!"

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.
