    Ray Poellot, sales manager, never used gimmicks or trickery (as did a few other companies) to convince me to purchase from Roland Slate. He also offered alternative products of similar quality that were cheaper compared to other companies. I am very happy with the new roof and aluminum wrap (to cover wood trim) on my 80 year old original slate roof home that never had a full roof replacement. Work performed was high quality. Follow-up: The review above was based on work performed on my house in Baltimore, and I still give that experience a 5-star rating. However, the estimate I received (by a different person) for a complete roof replacement at my house in Bowie was over twice the estimates received from 3 other licensed contractors. In addition, I have not received a returned phone call or e-mail made several weeks ago. I was really hoping to do business again with Roland Slate, but I will be getting the work done by another contractor.

    UPDATED RESPONSE: Mr. Hughes, I'm so sorry for the late response but for some reason I did not receive the notification that you had updated your review. I'm truly sorry that your more recent experience was not as pleasant as the last. Good communication and customer service is something we pride ourselves in. As for the price difference between our contract and the other contractors, I wouldn't be able to speak on that without having a full understanding of the situation. I imagine by now it may be too late and you moved forward with another contractor, but if not and you would like to discuss, our general manager would be happy to have a conversation with you and get things moving in a positive direction. Again we are very sorry for our lack of communication and would love the opportunity to make it up to you. 410-532-9037 Brittany Rich PREVIOUS RESPONSE: Mr. Hughes, Thank you so much for your feedback! Ray was very delighted to hear this. As was the owner and the rest of the team. We take enormous pride in our ethics and workmanship. We are thrilled to hear you had a positive experience from start to finish. We would love the opportunity to serve you in the future! Have a great day! Brittany Rich

    Roland Slate was amazing from start to finish. The team worked with me to resolve all the issues with the roof and provided me with all the extra paperwork that I needed. This is my second home I’ve used them for. Everyone was a pleasure to work with. I’ll definitely be back anytime I need work done on my roof!

    We got several estimates about fixing a perennial leak in the upper part of our slate roof that is not even visible from the ground. In their free estimate, Roland Slate gave the most comprehensive report that provided detailed pictures of the roof and its many issues. Their quote was a bit cheaper than another company's and it's clarity instilled confidence it would be done satisfactorily. We had them do the work and although it was a complete replacement it was done in a timely manner and all debris cleaned up.

    I had a great experience with Roland Slate. They came out quickly to look at the project, and expedited its installation, and bumped up the schedule to do the job following an unexpected leak from my roof.

    Roland Slate Service was recommended by neighbors. The crew showed up on time, worked through the day conducting repairs, and cleaned up debris. We're new to slate roofs so they explained some things to us as well .

Posted by Roland Slate Service Co., Inc. to their own Google profile 2 weeks ago. Their words, not ours.

A slate roof is one of the longest-lasting roofing systems available. With proper installation and maintenance, it can protect a home for more than a century. Even so, slate is not immune to damage. Storms, aging components, foot traffic, and failing flashing can all create problems that require attention.Aug 4, 2026Learn more
