"George Pindro replaced my deteriorating slate roof with dimensional shingles. Referral from my neighbor who did the same 6 years ago and is happy. George had the best quote of the few I got, for equivalent or better material. Description of work was very clear and detailed, came a few times to look and answer questions. Very accommodating of changes and additions, started work right away, finished quickly, very good cleanup afterwards. Very pleasant experience and the roof looks great!"

"I would like to thank the Home Genius Exteriors team of Calista, Caleb and Devan for another job well done! After having our roof replaced, we called them to replace our leaking gutters. They sent a crew out and within 2 hours we had nice new seamless gutters and downspouts. The proof is in the workmanship, because it stormed Tuesday evening after they hung them. Not a drip or overflow. Everything worked like it was supposed to. If you need a new roof or gutters, you can’t go wrong with Home Genius Exteriors. The price is reasonable and the workmanship awesome. I give them a 5 star rating"

"Toth Roofing did a wonderful job. Steve Toth is professional, knowledgeable, prompt and courteous. We needed someone who knows how to do slate roofing and he was highly recommended to us by a neighbor. In fact, our neighbors on both sides recommended him - he has repaired and maintained a slate roof for one neighbor and completely replaced an asphalt roof for the other neighbor.  Steve's crew was excellent. They arrived on schedule every day, knew exactly what they were doing, and cleaned up the job site perfectly. It was a pleasure to have them on site. We had the option to replace our small porch roofs on the back of the house with slate or asphalt and Steve gave us the pros and cons of each. We elected to go with asphalt for ease of maintenance more than anything else and he helped us choose a product that we would be happy with. They also repaired the rotted sections of the porch roofs after the tear-off and before nailing on the new shingles. The porch roofs look great as does the entire slate roof. We feel the price was fair based on the the work being performed, the time they spent doing it right, and the quality of the work. We had to wait a bit to get the main work done, but Steve had his crew stop out and address an issue with a leaking gutter before that since it was fairly urgent to us.  I will be calling Toth Roofing again to maintain my slate roof and to schedule two other projects-siding for a large dormer and an attic vent that needs repair.  I would highly recommend them to anyone.

"After our ceiling fell down from a leak in the roof, we had to find someone who could fix the giant hole in the living room as if it never happened, which proved very tricky since the ceiling was plaster with a special type of texturing. After searching high and low for top notch plasterers, we found Bob's number and gave him a call. Bob came out quickly and was able to put our mind at ease about making the repairs and gave a great timeline and quote for getting the work done. When the work was done, we truly couldn't tell there was ever a hole in the ceiling! Bob and his team did an excellent job repairing everything and matching the texture to the surrounding area, we couldn't be happier! They were all so courteous and did a great job making sure everything was covered up before they started and cleaned up so well afterwards, it was as if no one was there (and no hole)! If we ever have any plastering needs in the future, we would call Bob in a heartbeat."

"Was contacted fairly promptly and had appointment set up with my son for them to come look at my roof. Was called the day of the appointment that they didn't need to come because they had info about the roof (I'm unclear from what source - Google maps?). Was called that evening with price of $24000 to replace roof. I'm uncomfortable with the idea of shelling out $24000 to someone who hasn't even inspected the roof to see what condition it is in. It's possible that the roof is the original (>20 years old and therefore may be nearing end of lifespan) but I don't know that for a fact (having been in the house much shorter than that time frame). I asked for a written estimate of what they would do and their assessment of the condition - I have not received anything. I think I will need to obtain a roof inspection first and perhaps from an independent company."

"Zach is a hardworking and honest contractor. He replaced some leaking skylights, and repaired a section of roof that was leaking around another. He and his crew put in more than a full days work staying late to finish the job. His price was very fair and I would definitely hire him again. Of note, he also knows his limitations and did not attempt to work on a larger flat roof and gave me some recommendations for someone to call for that. Much better than working on it and having a bad outcome down the road. I appreciated this honesty."

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