"Central Roofing is an outstanding company. We had a very positive experience with it from the time we first contacted the company through completion of our job (we are return customers). In early March, a wind storm damaged the siding on our home, peeling off several panels and twisting others. My husband left a message with Central Roofing late on a Saturday after the storm and we received a call back from the owner on Sunday morning. The owner had a salesman contact us later that Sunday and he scheduled an appointment to come out to our home and assess the situation. The salesman was very helpful in working with us to get needed information to our insurance company and was willing to talk with our adjuster. We believe these actions demonstrate Central Roofing's commitment to excellent customer service. We were also extremely pleased with the final results. Central Roofing did a wonderful job removing the old aluminum siding from our house and then re-siding our entire house with new vinyl siding. Central Roofing also wrapped all of our wood trim around the top of our house so that we no longer have to have it painted every couple of years. We also had Central Roofing replace two kitchen windows. The workers were prompt, professional, and very courteous. They also worked long days and weekends to ensure the project was completed within the promised timeframe. When we started having some "nail pops" on the interior of our home from the work being done outside, my husband discussed it with the foreman and the workers modified the way they were installing the new siding to minimize the amount of "nail pops" on the inside of our home. After the work was completed, the salesman came back out to our home to look over the work and ensure we were happy with the final results. Overall, we had no complaints and will continue to use Central Roofing for any future roofing, siding, & window needs. In the past, we had Central Roofing replace a roof, install new gutters, and replace many windows. They are one of the best companies we have ever worked with and we highly recommend them."

"The roof was replaced in a day and the gutters the next. The crew was in and out and all the interactions we had were pleasant on professional. We have a sunsail and it required them to install some anchors by doing some custom work included in the cost of the new roof. Everything went mostly according to plan other than needing to shift schedule due to weather. I would recommend their services to anyone."

"Hugh inspected our old metal flat roof system and acrylic skylights. He provided us with two options: one for repairs and one for complete replacement. Both estimates were for superior materials and were very reasonably priced. He was upfront that we didn't need to replace the entire roof right now, but if we didn't we'd likely have to do more work in a few years. We elected to replace the skylights and do the complete replacement, which included fixing any damaged decking, installing a new base sheet, adding a layer of insulation, and a thick rubber roof system. Since it was March, they were able to schedule the work right away. They arrived early in the morning, removed the old roof and skylights, and put on the new roof system and skylights. They were done by mid-afternoon. The crew was professional, hard-working, and efficient. Most of all, I was impressed with the high quality of their work. They even cleaned up the bits of the paper from under the old roof that inevitably found their way all over from our yard---and our neighbors. I *highly* recommend Keith Roofing! Addendum. A few months later, a contractor had to install two vents for exhaust fans through the beautiful new roof. I wasn't sure how good a job they did, so I sent some photos to Hugh and asked if we could hire him to fix it. He said the other contractor's work would eventually leak, but his guys would come out and install new rubber around the vents---at no charge. Fabulous customer service."

"Everything that was promised was delivered. Quite pleased with the quality of the products and installations. They work efficiently. I had Power out to replace my siding, trim, gutters, and a few windows in 2014 and was so pleased that I now had them back out to replace my roof today. I will calling Power for future work down the line and would highly recommend them."

"I received 8 competitive bids for a full roof replacement on our 1901 Victorian B&B. We chose Exterior Solutions LLC, whose bid was 28% below the average. The 4,000 sq ft project included removing 35-year-old asphalt shingles, installing all new plywood sheathing, and updating roof venting. The roof has over 45 facets with a predominant pitch of 10/12, making it a challenging job. John A. and his team did an outstanding job installing CertainTeed Landmark Pro shingles. John scheduled the work while our B&B was closed and ensured the roof was sealed before any rain. He worked closely with our neighbors to minimize disruptions. Cleanup was exceptional—nothing left behind. We’re extremely pleased with the quality, professionalism, and communication throughout. Highly recommend Exterior Solutions LLC for any roofing project."

"Exterior Medics did an excellent job on our new roof. The were very professional. We had a great experience from the start of the sales process with Yong Hwang, and throughout installation and inspection. Pricing was competitive and fair compared to other roofing company quotes. Everything was done in one day and they cleaned up everything afterwards. They were also very considerate of protecting our outdoor plants and A/C unit. We would highly recommend them to anyone needing roofing services."

"They did an amazing job on house exterior: rotten wooden trim was replaced and all wood wrapped with aluminum foil. Very good communication, timely updates, even extremely cold weather did not stop the crew from working. Itemized contract and reasonable pricing. I would highly recommend this company!"

FAQs for natural slate roofing installation and replacement projects in Olney, MD

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.
