"Mike took the time to explain to me the work he would do; no question on my part was too much. I had a big concern about the mismatched slate on my roof. Because of the age of the roof and the natural fading that has taken placed, I questioned finding the right Vermont slate. Mike assured me that he could match my Vermont slate, and he did. I now have a uniform colored roof. Mike and Chris were on time and worked in a very professional manner. In addition, as he and Chris did the work, when he saw something else that needed a bit of attention, they took care of it. In all 37+ slates were addressed. Mike will be the person I call to maintain my roof."

"Simply put, Bob (the owner) and his crew were awesome in every measurable way. They score a 100 points on a 10-point scale as far as we are concerned. To begin with, Bob responded to my voice-message within an hour or so...he visited the project location the next day, and provided his written quote within 2 business days. Bob also maintained communication during the period from my initial call to the morning that the work began. Based on DELL'AQUILA PLASTERING's current workload at the time, a tentative date less than 2 weeks out was agreed upon, subject to us completing other work (wiring, plumbing, etc). Bob maintained excellent communication, and called to confirm the start date and arrival time. Bob and his team arrived at 8:30am as promised. Once the drop-cloths were installed from the entrance to the bathroom by the workers, there was a continuous flow as the work moved right along. The project was completed on time and under the budgeted estimate (WOW!). Cleanup was exceptional, as there was nothing that would indicate that a sheet-rock and plaster project had just been completed. Combine all that I have said above, with the friendliness and professionalism of Bob and his Team, and the timeliness and quality of the work completed, and you have a FIVE-STAR COMPANY ready to complete your project!"

"Everything went great from initial estimate through cleanup! This company was referred to me by a friend whose metal roof they had installed. Everything they did was professional, courteous & on time from beginning to end. The estimate was honest, accommodating and low pressure, the office was friendly, the workers were prompt & worked hard. Everyone was super easy to work with. Plus they did the work that some others weren’t interested in looking at bc it is a shared garage."

"Very well! Andrew the owner & his associates completed the job in two visits. The first was to power wash the cedar porch ceiling and decking/ railings which took about 2 1/2 hrs. Two days later (rain in forecast) they were able to polyurethane the ceiling & stain the rest in about 8 hrs. It turned out great and was long overdue."

FAQs for natural slate roofing installation and replacement projects in Southwest, PA

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.
