"It went incredibly well. I woke up one morning to a leak in my roof. I knew the roof was going to need to be replaced at some point, but I was hoping I'd get another year out of it. The roof was in bad shape when I bought the house. I immediately started calling all of the roofing companies I could find on Google. It was early so I was leaving voicemails. Kasey from James and Whitney was the first and only one to get back to me in a timely manner. He was incredibly helpful on the phone, walking me through how to put a tarp over the impacted area. He even swung by later THAT DAY to check and make sure it was installed properly and to assess the roof. I knew it needed to be replaced so we went right into talking about estimates. The estimate was within my budget but the new roof came with a FIFTY-YEAR WARRANTY for parts and labor. You just can't beat that kind of warranty on an asphalt roof. We were scheduled within a week and I had a brand new, perfectly installed roof within a month. Kasey and his team were super respectful during the installation. When the installation had finished, Kasey inspected every inch of my property to pick up any tiny bits of trash and leave our lawn spotless. The whole process was so easy and stress-free. 10/10 would recommend!"

"Kevin and his crew were very busy but came to me after a day's work to at least cover the roof with a tarp. He saved damage to the house with the extra effort. He and his crew also demonstrated the same high-quality care and workmanship. He determined the trusses were still good and didn't take pay until he felt the job was completed to high standards down to the protective trim. I knew what was to happen each day and the yard was cleaned each day as well. The best crew I've had in all the decades that I've owned houses. Photos of my home on his FB page."

"After our fire, I couldn't find anyone willing to recommend a contractor so I turned to Angie's List and picked NE Renovations. I couldn't be happier with our choice. NE Renovations is everything I hoped for in a contractor, and more. Richard and the crew have been delightful to work with. Communication has been easy, estimates accurate, and when a problem arose - the plywood under one of the roofs was rotted - they gave us choices for fixing it. Everything is up front, no surprises. The crew arrived every day as promised and worked full days. And they are nice guys - polite, considerate of our home and dogs. Again tidiness was big. I would absolutely use NE Renovations again, and happily recommend them to friends. They made our house look beautiful!"

FAQs for natural slate roofing installation and replacement projects in Penobscot, ME

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.
