"Jake and his crew did a great job, I was adding solar panels to my roof and wanted new shingles and plywood to support the installation. I called several companies and found JAGG to offer the best price. I was very happy with the work, one day, full crew everything done. very impressed with the cleanup, not a nail to be found. LI Solar even asked for there information!! If you need Roofing , siding or Windows give JAGG a call. Excellent, 5 star work!!"

"I had a great experience with the Exterior team company. Ronald was very punctual in the initial visit for an estimate. I explained to him that I could not be there and he scheduled another time the same day to return to discuss the estimate. He was on time that evening as well. He was very fairly priced. We scheduled the job a month out. He had all materials delivered the morning of and the crew was on site by 7 30. They worked hard throughout the day and as a thunderstorm was coming, they worked tirelessly to cover the remainder of the roof. They returned the next day, completed the job and cleaned up. The roof is looking great. I would highly recommend Ronald and his crew."

"I hired King Quality only 2 weeks ago and within the 2 weeks they came to my home, gave me a price, installed the siding and left my house spotless. I was very nervous making the initial call but they put my mind at ease. It was a pleasure working with them from my 1st call into the office speaking to the ladies then speaking with Jeff to the crew foreman Billy. They definitely lived up to there name. I received King quality!"

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