"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."

"Acorn Home Improvements,Inc. did work on my elderly mother's home. The house needed new windows. The old ones were drafty and were hard to open. In addition to replacing the windows, we decided to have additional insulation installed in the attic. Both crews, one for the windows and the other for the insulation, were professional, polite, on time and did a great job cleaning up after themselves. It was a pleasure to deal with a company that was accommodating and completed the work as agreed upon. Mom and I found their pricing was very reasonable. Since I live out of state, I was not able to be there for the entire process so it's comforting to know that there are companies that are honest and reliable. When the project was completed mom was thrilled with her new windows and how easy they were to open and close. Further more with the proper insulation, mom found that her utility bills have decreased which is an added bonus for someone on a fixed income. Mom and I highly recommend Acorn and would definitely use them again."

"I went to Angi trying to find a reputable company to change my siding, roof, and gutters. I trusted my gut to go with Home Genius because of their reviews not only on Angi but on google as well. I reached out to Home Genius and they were extremely quick to respond which was a great sign to me. Breanna was the one to respond ON HER HONEYMOON. I got a kick out of that ð . At the time of the sale, I was blown away by what Tre had presented to me. For each project, there was an incredible amount of knowledge thrown my way from both him, before I signed the dotted line, and Taylor the project manager when it came time to execute. Tre wasnâ t pushy or high pressure like a lot of other companies. When it came time to install the roof,siding, and gutters the crews did a most excellent job from start to finish and the clean up was unbelievable. Not a nail, not a piece of anything left behind. Each crew specialized in what they were there to install. Taylor would call me and visit every so often to check in and update me on progress with all of my projects. As Iâ m writing this, I canâ t help but thank everyone involved in making this outcome possible. Just look at my house! Itâ s BEAUTIFUL."

"Work went great. Mike accommodated a last minute adjustment to add a second gate. Team also had to install 2 additional panels (original delivery was short these 2 panels). Original fence delivery was installed in roughly 6 hours. They installed a temporary workable second fence until I got the new one and put in a temporary barrier for the 2 missing panels. Took a couple weeks later to get/install the second fence and 2 additional panels... I didn't know Carl's actually makes their own fences until after the original delivery was installed so completely understand the delay. Very professional company. I'd definitely use these guys again."

"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.
