"The crew at James & Whitney co were extremely friendly, courteous and went out of their way to make sure that we were happy with our new roof. The job was done fast and is of wonderful quality. Beyond that, this is a company that truly stands behind their work, as they have reached out to me several times in the past few months to ask how the roof is holding up. I truly couldn’t recommend James & Whitney highly enough to anyone who needs work done on their roof."

"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."

"I would definitely recommend Alec with Spartan Roofing. They gave us the best price and most expedient service. He was very communicative throughout the entire process. It was a pleasure doing business with Spartan!"

"Work agreed to: 1) level a slope, 2) build stone patio, 3) install fence. Period of performance told by the contractor was 5 days to a week and a half. Work started May 16. By June 3 project was not half complete. Contractor delivered pile of dirt and pile of gravel and railroad ties for retaining walls. Contractor did some work. If reasons given were accurate, then some missing days for medial were reasonable but after three weeks there were several issues: 1) the work was only about halfway complete after three weeks, 2) the slope remained which can't be used since it's needed for a shed, bee hives, and raised beds, 3) the rear retaining wall was already leaning and losing dirt from only one rain. With these concerns I consulted two other landscapers who immediately identified problems with the wall as well as the slope, that it would not hold through one winter. In addition, contractor may not have contacted Digsafe, public utilities, and city public works for permission to proceed with any excavation. I have a lot more details including inconsistent texts"

"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.
