"Joe is a project manager for Home Genius Exteriors. He's supervised the installation of my replacement roof. When the foreman informed Joe that some necessary supplies were not part of the shipment delivered, Joe immediately left to get those items from the vendor. Once the job was completed Joe return for a final inspection and even went around with a magnet to make sure all nails were picked up. Joe answered all my questions and was congenial and represented himself well as a professional. I highly recommend Joe to any client or employer."

"As with the estimate, Richard arrived exactly on time for the insulation addition, and he and Jim performed flawless work with a freindly and professional attitude. They worked quickly and installed 48 styrofoam vents in the rafters in the confined space of my attic (to allow for critical airflow through the soffit).  In addition to the excellent service, Rick also explained the fascinating machinery and process for blowing the insulation into the attic.  After the job was finished, the invoice was exactly the quoted estimate price.
I would quickly hire them again, and I highly recommend this company and employees to anyone who needs insulation.  Richard stated that the savings in heating/cooling costs could exceed the insulation and installation cost within 2 years. I should have done this much soooner. Thanks Richard and Jim !

"Had the roof, gutters and siding replaced. A lot of work removing the old and installing the new. The crew of 4 showed up every day till the entire job was done. Never was I left hanging with a no show day. Very happy with entire process. Also important, the original estimate is what I paid. No cost over runs. Did have to have them return for some minor corrections and they quickly responded. I'd recommend Blue Ribbon and hire them again. Four stars to Steve and his crew, and to Evan (owner / estimator ) for the best price."

"I called Jonathan on a Monday morning and he returned my call the same day, and came out the next day to look at the job and provide a quote.  I accepted his bid and he got started the next day.   He provided thorough information about the various product options. The craftsmanship of the new boardwalk is so much better than what was there before. He did quality work in the time promised and cleaned up completely after the job was finished. I was very pleased and will have him back to do the next phase of our decking replacement when the time comes.

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