"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 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."

"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!"

"We have a two story home in Patchogue that had a leak that resulted in water in the walls of our attached garage. We could not locate the cause of the leak. We contacted Exterior Team Home Services who quickly located the source of the leak which required us to replace the front roofing of our house. It was done very quickly at a fair price. We were also impressed on how they made sure the old roofing material did not get into our front lawn or plants. They were meticulous in the way they treated our property. A job well done."

FAQs for natural slate roofing installation and replacement projects in 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.
