"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."

"Iâ m going to begin this review by saying, I have never hired someone to do a job on my house where I have been completely satisfied with the labor and the finished product. Until now. I just hired a company to remove my existing shingle roof and replace it. Not only is the finished product of excellent quality, but the technicians were extremely diligent in making sure everything was done with precision. The entire job even down to the clean up afterwards is outstandingâ ¦. I highly recommend Coxs Roofing and I will be using them whenever I need roofing work done. Oh!

"We were 100% satisfied with Washingtonian and with their work building our addition and deck. Not only was the workmanship and quality of the construction outstanding, but they operated with honesty and integrity. Their goal was our satisfaction and building a quality addition and deck. They accomplished all three and were reliable, dependable and conscientious. At no time did we believe that they had over-committed or were unable to deliver on what they had promised. They never cut corners to rush to another job nor did I ever feel that they were not spending the necessary time to ensure that the work on our job was thorough and complete. Travis, Kris and their crew were 100% professional, communicative and transparent. We will be using Washingtonian again, without hesitation. Our experience was excellent and they did an awesome job."

"Thomas M was an excellent technician and did great work fixing all the basement windows around the house. These windows are difficult to find a replacement but he was able to repair and repaint them. The other technician was Pablo He worked on caulking all the windows around the house and he did some filling work on the garage sliding doors You did a good job, but Pablo left his trash around and didn’t pick up after himself so Thomas M and I did that on the third day. It took three days total, but it was two men for two days and one man for a 3/4 of a day actually. Although I’ll probably get charged for a full day, since it went past noon. The labor portion is the most expensive and a little higher than I initially anticipated. So, I was hoping for a quicker turnaround, but overall quality work was completed. I would highly recommend Thomas M as a technician to do future work. He’s very knowledgeable, friendly and does a great job. I would hire again but include more details in the contract language."

"Had windows and doors installed by this company. The window installation went great. The bad news is that they do not seem competent at installing door hardware. My door has not latched properly since they made some unwanted modifications to the hardware (it worked perfectly before they started modifying it).have had them out three separate times to fix the issue they caused with the door latch and lock. Every “fix” they do seems to make the problem worse. I would steer clear of this company for door installations."

"Spent ~$50,000 on a new roof with them. Thought everything went well. Years later discovered that they had not sealed the cricket on the chimney well enough. Discovered water coming in and eventually rotting the wallboard, studs, etc. Had to replace entire wall. Called them about the issue, they sent a rep. He said it was the chimney's fault, it was leaking. Not so, opened the wall and ceiling and had another roofer come spray water on the chimney, nothing, no leak. Then sprayed water on the cricket, water came in. Exterior Medics would not admit any fault. Had it repaired, no leak, no problem since then. Had recommended to a friend, never gain, he also had a bad experience. DO NOT USE IF YOU WANT QUALITY WORK AND A COMPANY HAT STANDS BEHIND THEIR WORK."

"We were looking to increase our attic insulation and met The Home Doctor Company at the Capital Remodel and Garden Show in February 2025 as well as some other companies. We consulted with several companies and decided to go with The Hone Doctor for our attic insulation. The company rep, Chris Lear, was very good explaining what they would do and why our attic needed R-38 insulation. I knew we needed more but did not realize our attic was only R-13. I have worked with numerous contractors before on projects and felt this was a really good company plus they have great reviews. The installation of the attic insulation went very well. They do install siding as well but decided to put this project off for now. Would highly recommend this company."

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