"Awesome Contractor — Fair Pricing & Quality Workmanship Geno's Siding & Roofing Company replaced my gable vent today. It was the first time that I used this company, and I will absolutely use them again. I am retired, so I watched the entire project and was amazed at how skilled and meticulous the worker (actually the owner) was. The next time I encounter something that I can’t personally fix, I am calling Geno's Siding & Roofing Company at 215-971-6292. Howard (Howie) Walters Langhorne, PA"

"They came and install insulation board to low area and Epdm rubber roofing to eliminate water backing up underneath roof. Clean off any debris and glue down insulation board install termination bar across we're shingles meet Gutter so water can't go under shingles and then install rubber over entire Flat area. But as we got some heavy rain within a couple of week they had to come back to fix it after that had no leaks they came back once again to fix the drain. Also my neighbor like there work and hire them to do there roof. All in all great job."

"I hired Home Run Roofing to replace by roof and gutters, and I could not be more satisfied with the overall experience. They offered multiple options for my project, all of which were affordable and competitive. Reviewing and selecting a work estimate and applying for financing was a 2025 customer service experience (as opposed to a CS experience expected 10, 15, or 25 years ago), which in part distinguished them from other companies I met with. When I had any questions during the project it was very easy to reach my my contact at Home Run Roofing to answer my question. The crew assigned to the job were outstanding. The work was completed within two days (one day for the roof, the second for the gutters) and everything was thoroughly cleaned up afterwards. Since the project's completion I have received multiple compliments about how beautiful the new roof and gutters look."

"The owner, Jim, was very professional and a pleasure to work with. He is willing to answer all questions and work with you on any issue. His team arrives on time and works very hard to get the job done in a timely manner. Roof replacement can be very messy but his team cleans up the place really well. The materials he uses are high quality and the house looks fantastic. From the road you can tell the roof was done by professionals. What a difference! His price is fair (we got numerous bids) and the quality is exceptional so we were quick to recommend him to other family members."

"So-so experience. Job was bid and performed in the depths of the recession - I think he priced it so low that he needed to cut corners. Plus: did job quickly, when scheduled. Old roof was removed with only medium amount of mess. New roof went on OK. He did an OK job installing a skylight in the new roof. Minus: He reused the old gutters, which I would not recommend anyone else do - they were pretty battered by the time they had been removed and replaced. Some of them still don't drain right. Here's the worst part: on the last day, one of his guys fell off the roof. My wife was in the dining room and saw him bounce off our back stairs and land on the grass. Fortunately, he didn't seem to be badly hurt, as he ultimately landed on boggy grass. However, Scheinfeld, when told about this, took more than an hour to show up, and the injured worker called us a few days later asking for our homeowner's policy info, thinking that we would be paying for his medical care - can you believe it? I run a small business and am very familiar with the concept of Workmen's Comp - no telling what was going on between Scheinfeld and his workers, but something seemed to be very, very wrong. A couple of our gutters still don't drain right, despite several calls to have them adjusted. But the roof no longer leaks."

"This was the best experience I ever had with a contractor. Dave explained the entire process, provided us with a detailed estimate accounting even for the nails. No sales pitch no runaround, just up front & honest. Price was great 20% less than the other guys. Installation went fast and they left the property cleaner than they had found it. Super happy, I highly recommend EarthRise."

"There was a small leak several months after they installed the flat roofs, which apparently was a caulking issue. BRyan came out and fixed it and there was no leak thereafter into the room below. They gave a 20 year warranty so I wanted an inspection this year to keep the warranty valid. Bryan came out again and was very thorough in his inspection of the three flat roofs that they installed the previous year. Everything looked good. I am very happy with Tycos. Also the owner Christine whom Iâ ve exchanged emails with is very prompt in her responses and courteous.Itâ s nice to know that they will back up their work! PS. Brian is not only thorough, but very reliable. When he was going to be a half hour late he gave me the courtesy of a phone call."

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