"Very happy with the quality, timing and price. Good communication as well. The old roof had to be removed from both the main house and detached garage. The house had multiple layers of shingles that needed to come off and the garage also had the original cedar shingles in addition to the many layers of asphalt shingles. It was very messy getting the old roof off but the crew was really good about cleaning up. At the end of the first day the yard was a clean as it was before the work started. The entire job took only two days and the crew was able to start work the same week I signed the contract. Because less plywood was used than was quoted, the final price was even a few bucks less than the contracted price I agreed to. So overall I am very happy. Was a really smooth and easy project compared to past home projects."

"This was the best experience I have ever had dealing with a contractor. Jacob and his team went above and beyond my expectations. Jacob was able to stay within our budget. Cost that was estimated is what was invoiced at the end of the job. We started off with just getting our roof replaced but then decided to put a new roof and siding on our garage. Everything was done within two days. Left the outside of our house spotless. I recommend JI Roofing to everyone that needs to get their roof and or siding done."

"This was a large job which required removal of the old roof - multiple layers of asphalt shingle and cedar shake down to rafters. The house is a large old Victorian with multiple angles and outcroppings, and very steep. There was also a one car garage. As promised, Royal arrived on day 1 - a Monday in 12 degree weather - with 3 dump trucks, several other trucks with men and equipment and over 30 workers. They swarmed over the house and by 10 AM the roof was stripped to the rafters and by the end of the day new plywood, underlayment and shingles had been installed on more than 3/4 of the roof. All work was completed in 4 days. Every night the property was thoroughly cleaned up. Progress was provided during the entire job by sending photos taken with a drone - terrific! Overall we were impressed and pleased with the work and the fact that it truly took 4 days. We had seen other jobs in the neighborhood take 3 weeks or more to complete. You pay for this kind of service - it is not cheap - but it is totally worth it. In addition, all of the workers and the project managers are very professional and attentive to your needs. I'll never have to use them again for this job, but I would recommend them in a heartbeat if you need a roof, gutters etc."

"Highly recommend from Express Way Roofing. They sent a professional team to measure for the replacement of my skylight and explained the complete installation process. When the skylight arrived they prepped the areas inside and outside my home with drop cloths to ensure job cleanliness. After rebuilding the curb the skylight was installed and sealed. Excellent service! And I love my new skylight."

"I cannot thank Paul specifically for putting up with me! From the beginning I had a vision along with a number of pics from Pinterest of what I wanted my house to look like. For starters my home was covered in old stucco and a lot of rotted wood underneath which was a messy job to remove. His team actually not only replaced all the damage but even removed my front living room window, reframed and replaced, as well as sheet rocked, spackled and painted the inside seamlessly. Paul stated the entire process would take 2-3 weeks. Well not only did this transformation complete in just under two weeks but either Paul himself or someone from his team stopped by daily to check on the job. Any questions or concerns were answered immediately and his crew were an absolute pleasure to deal with. I can sincerely recommend Brothers Aluminum to anyone looking to have any construction done to their home!"

"Installation Date: Late August 2022 The roof installation and gutters were installed and look great. I DO NOT like what they did with the flashing on my chimney. It looked cheap, put together in haste, and with really bad and cheap materials. I had to call and argue with a representative to explain to him that the job they did on the chimney was horrible and that it had to be corrected. He tried to convince me it was the way it's done. I then showed him my neighbors house who had their roof done by another company. Power Home charges a premium and it didn't seem like they were very invested in the job they were doing. Additionally, the trash bin that was delivered was way to small and all the trash didn't fit. As a consequence, they left trash in front on my house and on my property for weeks after. I had to call a second time and resort to begging to get them to come by to pick up the trash. Overall, I feel like they didn't respect the job they were doing, the final touches were horrible, and they didn't treat my home with love or respect (as if it were their own home). Also, there is now a huge gap between the siding and the new roofing material. I fee they should have found and budgeted for a solution for that issue in the form of a bit of siding or flashing to minimize that gap. Now water and critters will get in through that gap. Overall, if I could do it again, I would defiantly NOT chose Power Home Remodeling. I DO NOT recommend them."

"Tony suggested and I agreed to replace instead of repair the roof. I had 3 existing skylights. When Steve came to install the roof he told me he could not replace the skylight flashing without replacing the skylights. I believed him. I asked Tony to send me a statement in writing confirming that the skylight flashing could not be replaced without replacing the skylights as well. After three calls, he provided that letter today."

"When I needed a new roof, I called Jake. He handled everything from beginning to end. I received an estimate immediately, and a crew was on site in no time. The crew was neat, fast, and thorough. When they were done, you couldn't even tell someone was there...other than the amazing looking new roof! I highly recommend Jake and his team!"

FAQs for natural slate roofing installation and replacement projects in Central Islip, NY

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.
