"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."

Another family member had used Manny in the past and was also extremely happy with their new roof!"

"Good job. Alexander came when he promised, sized up the work, recommended I keep old gutter but install new hangers. Fair price for two guys on ladders for an hour or so."

"The installation process went as planned. After the insulation, I expected a follow up to see how things went. After all, that's what happened after they did my window installation. No follow up took place. I gave it a few weeks to see if they would call or come by to see. After waiting I placed a call to address my concerns. The roof installation went fine, but they left debris on the brand new windows they installed along with splashing some black substance on my siding. I guess they expected the rain to wash it all away. They also left large piece of wood in my drive way and nails in my driveway and around my house. I was assured that someone would call me back since the members of the team handling my account was in a meeting. It is now been a week and no call back. That must be a heck of a meeting."

"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."

"I cannot say enough. I had a total rip off of the roof /siding and replaced. Being a part time contractor myself all my life I was going to attempt the job myself with some friends. But at 60 years old my wife was totally against it. I did some research and found AQ. One of the best decisions I have made in my life. Young, energetic , confident, trustworthy, professional, all the workers taking pride in their work. They went above and beyond with the little extras that makes the job. The cleanup...perfect. In this profession I would always tell people "you get what you pay for". AQ is worth every dime, from start to finish. I'm getting daily compliments from neighbors. Mike and Denise G"

"I want to have my roof inspected for a potential repair or replacement. Robert responded fast and provided honest review by telling me that my roof is coming to the end of the expected life but didn't push me to replace or repair right away. Additionaly he found cracks on my chimney that I was not expecting initially. I am happy to hire him to get the chimney fixed and potentially saved a lot of money for a fix down the road. I will highly like to hire Robert again for roof replacement."

"It went better than I expected! Sky Tech was recommended to us by our realtor who just had her roof replaced. I dealt with Blanca via e-mail when setting up appointments to get quoted and replace our roof, she was very helpful, polite, and responsive. Dave, the owner, came out to inspect our roof on a Saturday and sent me a quote on Monday. The quote was very detailed and extremely reasonably priced. I signed the quote, sent a check for half the quoted amount, and picked our shingle color. We were scheduled for the following Thursday. A pallet of supplies and materials were delivered two days prior. The Sky Tech crew arrived around 7:45 am and were finished with the job by 12 noon. They threw a netted tarp type of material around the entire house to catch all of the old roof shingles and other materials. Some guys were on the roof putting the new roof in place and some guys were on the ground cleaning up any materials that may have missed the tarp. Before leaving, they combed the perimeter of the house with a magnetic tool to pick up any nails or other metal objects. Dave, came by around 3:30 pm to inspect the completed job, take back any leftover roofing materials, and do a final scan of the property for any missed roof pieces or metal objects. He even nailed part of our soffit that had a little sag as well as removed a broken de-icer that was stuffed into the gutters from the previous home owners. Due to the structure of our house and property, we don't have the best vantage points to see our roof. I have attached a photo though of the new roof, best shot and angle I could get. I would and will definitely recommend Sky Tech for any roofing needs, as well as any other siding, window, or deck needs. I will definitely go to Sky Tech in 20-25 years when our roof needs to be replaced and when we decide to reside our house."

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