"The crew was very professional and did the work quickly. Nolan did a great job explaining the process to us and made us feel very comfortable in navigating the roof replacement. We had a lot of fun with him and the roof was installed quickly and in a timely fashion."

"Western Pa. slate arrived and offered to assist, on the spot, with my problem. This was enormously helpful, as the roof had been leaking and more bad weather is forecast, and winter is around the corner. I was very pleased with this, and would be quite comfortable hiring them for a larger job. I would give them an A+, if possible!"

"The take away: Impressive! I'd hire him again without any hesitation and will recommend him to anyone who needs plaster work done. I had several areas in my house that needed plaster repaired from a roof leak and from a plumbing drain stack replacement. Other companies wouldn't take on the job or wanted $6K to $8K and a week to do it. Robert came in, took a quick look and some pictures and quoted me at $1,700 and could do it all in one day! Sounded too good to be true, but with all the good reviews he has, I hired him. He wasn't booked up, so I hired him on Monday and he scheduled the work Thursday and then finished everything in a half day. I think everything is done extremely well! The new plaster blends right into the old plaster. And that's the thing - it's plaster. He's able to do it in one day because he puts up sheet rock and plasters over it rather than putting up drywall and putting layers and layers of joint compound on the seams, which requires time to dry, then sanding, repeat. With plaster, you put it on once, smooth it out, let it dry and it's done, and frankly looks better that way. Anyway, I have absolutely nothing but good things to say about the experience and highly recommend Robert!"

"Can't remember at this point what we paid with our deal. In general, it
was very difficult to make arrangements, and the company tried to not
honor the deal because it was so long after the date at which we bought
the deal. However, it was late because they did not return calls for
several months. We had to push hard to actually get the service paid
for.
When they finally arrived, they were responsive and knew their work very well. However, there was no effort made to hang plastic or other barriers during the demoing of old plaster or sanding of the new. This was very upsetting, and when we pointed out the oversight to the owner, he was very apologetic. Unfortunately, the damage (in the form of many days of thorough cleaning throughout the house) was already done!
The quality of the actual finished work was quite good.  I would hire them again based on the quality of the plaster work, but with very careful oversight into their prep and an expectation it would take some time to get them to the job site.

FAQs for natural slate roofing installation and replacement projects in New Kensington, 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.
