"This company is Amazing! My husband and I needed to replace our 20 year old roof. We had heard so many great things about Certified, Inc., and their great customer service and quality of work; so we called. The crew was so friendly and knowledgeable and before they left they made sure the yard was completely cleaned up and that we were happy with the installation. I would recommend this company to anyone..they are no pressure, they took the time explain everything and they are honest! Thank you so much..I love my roof!"

"I’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 outstanding…. I highly recommend Coxs Roofing and I will be using them whenever I need roofing work done. Oh! And they also had the best price quote out of three estimates I received. 1121 Roland Heights Ave. 21211"

"Had our roof replaced, looks like a clean install. Trey was easy to talk to and was very assuring. We'll see how the roof holds up against this weekend's snowstorm or whatever's coming our way. Yes I copy pasted my own review from Google Reviews."

"I sought out three bids from highly rated Angie's list roofing companies. I eliminated one company that would not provide an estimate unless they could present it in person with my wife present (code for high-pressure sales). The second company was great, but did not get their bid to me until almost a week after they promised it. By comparison, Joe Makay got right back to me on first contact and every time I had a question. He was able to work my project into the schedule within a week and got got the entire large and complex job done in just two days. The end result was outstanding and well worth the price. I only rated their price as a B because their cost was somewhat higher than the other (larger) company that bid; however I went with Mckay because they were more responsive and customer service focused. I felt confident they would take good care of me and they did just that."

"I met David Garner of Garner Roofing in Harford County, Maryland. David was prompt with the appointment and listened to what I wanted as far as the work. Mr. Garner communicated with me during my contractor selection and his contract offered the best price for the best products. David shared with me the new technologies of roofing and explained the beneficial changes of that work and how it would enhance the property appeal and result in longer warranties. Garner Roofing was fast with the installation, did an efficient clean-up and he returned after the job to ensure my complete satisfaction. I highly recommend Garner Roofing and if you need a new roof or are considering replacement then I endorse David Garner to assist you in your decision. The new roof at my home has the PRO Architectural Black shingles that are thicker and heavier than standard shingles. It has a 130 mph Wind Rating, 15 yrs. Algae Warranty and a Lifetime Shingle Warranty with a 10-year transferable replacement with no pro-rating. My new roof is incredibly beautiful and the new look provides a striking difference to the old, white, stained roof that was replaced. Thank you David for an Outstanding job! My compliments to your crew for a fast, professional installation with absolutely no damage to my landscaping or other issues."

"Great experience from beginning to end. I had previously used S&K for a gutter replacement and some roof repairs. This time I decided to have the whole roof replaced. 100% satisfied and would hire for another job again. Thank you S&K!"

"I just wanted to give a big thank you to John Cisna for working with us, answered all our questions and informing us of all the things we needed to know about the process of getting a replacement roof and most especially the price was great and reasonable. The installation went smoothly, George and his team came out early, cleaned up everything and finished it the next day. They were very efficient and did a great job on our new roof. Definitely, I will refer Walter Brown to my friends and family."

"We highly recommend American Home Contractors. The sales team was very knowledgeable about the roof replacement process, had all of the samples needed to assist with our decision and provided a list of addresses so we could drive by an see completed roof projects. They are a master elite GAF roofing contractor, which was important to us in selecting a contractor. The contract process was hassle free and they addressed all of our questions. The work crew was very efficient and professional, and left our property in a very clean condition. The finished product looks great. We would use AHC for additional projects in the future."

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