Get matched with top natural slate roofing repairers in Gaithersburg, MD

"Certified roofing did very well. They were the first to respond to my Angi query. Tim was smart, quick, and had an excellent work ethic. We had a slight miscommunication on what the job entailed, which is being cleared up as we speak. I would definitely hire them again."

"We had our roof replaced by Springfield roofing and they did an excellent job. Andre was easy to work with, professional, and timely. We are really happy with the work!"

"Came up, took a look, told me I DIDN'T need a replacement, just some repairs, qouted me his price, we shook hands (Found out he was a fellow cigar smoker so I passed him a couple), he left, sent me the same estimate over email, I agreed, his men showed up and in less than an hour they had the repairs done. Now the thing is: He COULD have come in sounding all Doom & Gloom telling me the roof was about to cave in - NOPE! He could have given me a jacked up price - NOPE! His crew came, the saw, they fixed. Sadly, in 2026, that work ethic and honesty are becoming rarer every year. Definitely would recommend! 👍👍👍👍👌👌"

"They charged me more than I was expecting. My attic was taller and they had to put a bigger tube in. One of the areas in my house is somewhat dark during the daytime. What they do is cut a hole in the attic like similar to an attic fan and put a hole and put kind of a globe looking thing which basically allows the natural sunlight to come in. They install an aluminum tube and it can be bent to where you need the light and then put a cover on it. I have mine in the middle of the house where my stairs are at because it was kind of dark there with the rooms around them. I have had 1 or 2 minor issues and they came over to fix it for me other than that it has been alright. I had researched the parts and they was like $200 to $300. I thought it would take a couple hours and maybe $100.00 or $150.00 an hour but it cost me more than $1000.00."

"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 thought Presidential did a good job replacing my roof. I thought the pricing was fair and the job was done from first contact with the company to finish in ~1 month. I would use them for home repair services again."

"Roberto was on time, assess the roof and provided repair solutions. I would recommend this company for repairs."

"Very pleased with the entire roof install project. I would recommend them to anyone looking for roofing repairs. Dylan and Allan's crew handled everything seamlessly from start to finish."

"Quick came out to inspect my roofing problem and made proper repairs after carefully explaining the process."

"I do not know the price as my husband took care of it. I think the thing was they came out and they had three crews working and they came out and got it done. The guys that worked on roof worked very hard. They did there job. We did have a problem afterwards but that may have existed beforehand but they are coming back to look at it. They had replaced rotted boards and fixed some leaking from the gutters by replacing them. They're responsive, there is a lot of phone tag but they always call back. But in today's world things are different than what they were long time ago. They were on top of it. They came when they said they were going to. They worked right thru and they worked hard. We never got another estimate from anyone else we just went with them."
