"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"

"I couldn't have been more pleased with Charm City Roofing. Home repairs, especially roof repairs were something I dreaded to think about. My experience with Charm City Roofing changed all of that. Starting with my point of contact Mac who did a WONDERFUL job explaining the process and providing a comprehensive step by step of how the installation of my replacement roof would be completed. My home currently has solar panels which needed to be removed before the installation of the new roof could begin, due to the slow response from the solar company this took over 4 months! Dispite this headache, while waiting for the removal the Charm City Roofing Team checked in with me periodically, maintained my tentative install date and continually assured me they would get the job done. The roof was completed as promised and I couldn't be more happy, the installers showed up on time! roof was completed in one business day! (Again as promised) Yard was cleaned up Completely of every material."

"The service was thorough, I was given a free estimate and timely response concerning the contract. We all got on the roof and looked at the issues together. The challenge I had with choosing this contractor was that they do not offer financing. The quoted price was $26,000. To be clear, they we're going to allow a portion of the total amount to be paid off over time, however, The expectation was for us to come up with 10k+ upfront for materials. After receiving a second opinion, another contractor was going to be able to do the same work for less money with financing available. I don't think there was anything dishonest about their estimate. The cost they quoted me for repair was simply not in my budget based on their financing terms."

"They provided pictures of the holes in the roof beforehand.  Discussed what was going to be done.  At the time of work, it went very well.  The entire job took 2 days.  The crew was friendly and took the time to find my leak in the roof and repair everything to my standard.  No more leaks!

"It was a positive experience. We worked directly with the owner. He was very honest and knowledgeable. He took the time to answer all of our questions and did a great job matching our existing siding. He would be my first choice for any future roofing or siding needs."

"This is the first review I have ever submitted for a contractor. However, when a company offers this outstanding level of service they have more than earned a five star rating! After a severe windstorm damaged my roof, I called my insurance company and then researched / contacted several roofers in my area. As a result of so much damage most roofing companies were extremely busy. Walter Brown was the only one who had their staff working diligently to take calls, and somehow managed to fit me into their schedule even though they were inundated with emergency work. Two workers arrived as the rain started and tarped the damaged areas. Everyone at Walter Brown consistently replied to my emails and continued to stay in touch with me as we worked through the color selection and scheduling of replacing my roof. I researched brands of shingles before John Cisna came to my house to discuss the brand that they install. Finding out that they install the brand that I had found was the highest rated brand on the market confirmed that they had high standards both in the products they use as well as in the quality of work that they do. The crew who did the job was absolutely amazing, professional, courteous, and meticulous in making sure every detail of the roof was perfect. They completed the job in one day, and the young gentleman who went through the inspection checklist with me was thorough, and made sure that every detail was addressed to my satisfaction. It was a real pleasure working with Walter Brown Roofing. Everyone including the office staff, owner, management, and work crew were all a real joy to work with. My sincere thanks for a job exceptionally well done!"

"He did a real good job of cleaning up. He has a helper and he always works with him. He does not put him on the job and come back and check later. He did a good job and he was supposed to give me an estimate on repairing of the wall. He was honest and hardworking and that is why i went with me. I am concerned about matching colors on my roof and he paid details to that. My brother said however they had not fill up a couple of ports on the roof. He thought they over looked it other than that he did a good job."

"GREAT JOB! OUR 2300 SF ROOF WITH TWO LAYERS OF OLD SHINGLES WAS REPLACED IN ONE DAY WITH AN UPGRADED SHINGLE PRODUCT WITH A LIFETIME GUARANTEE. THE NEW ROOF LOOKS GREAT AND HIS CREW DID AN EXCELLENT JOB OF INSTALLATION AND CLEAN UP. WE COULD NOT BE HAPPIER."

FAQs for natural slate roofing repair projects in Aberdeen-proving-ground, MD

If more than 30% of your slate roof is damaged, it's time to consider a full replacement. This will prevent further deterioration and avoid costly recurring repairs. A professional slate inspection (costing between $130 and $360) can confirm whether repairs are sufficient or if a full roof replacement is the better option.

A slate roof can last anywhere from 60 to 150 years, depending on factors like installation quality, regular maintenance and repairs, and local weather conditions. Compared to materials like clay and concrete, which often last around 50 years, a well-maintained slate roof offers superior longevity, durability, and long-lasting aesthetic appeal.

Yes, you can use temporary patch solutions, such as roofing cement or patchwork, to provide immediate relief for minor leaks or underlayment issues observed from inside your home. However, these provisional fixes do not replace the need for a permanent, professional exterior repair, which is necessary to ensure the long-term integrity and weather resistance of your slate roof.
