The Durable Slate Company: Washington D.C.

605 Lofstrand Lane, Rockville, MD 20850
Serving District of Columbia and surrounding areas



The Durable Slate Company was founded in Ohio in 1986. Starting out as a small company with big dreams, it grew into one of the most prominent installers and handlers of slate and clay tile roofs in North America. By giving Durable’s craftsmen the proper training and tools, we can ensure that each roof we tend to is given the proper care and the attention to detail it requires. The historic methods we use to work on roofs are tried and true and guarantee that we will produce an authentic and aesthetic product. In addition to slate, clay tile, and metal roofs, we also specialize in the installation and restoration of copper gutters.


The Durable Slate Company: Rockville branch services the entire Washington DC and surrounding areas.

Our Customer Relationship

Built on Respect & Mutual Understanding

We believe homeowners have the ability to make the best decisions. All they need is the best information. Our estimators are the information gatherers who bring photos, explanations and recommendations to you. While some roofing estimators exploit the lack of knowledge of those outside of the trade, at Durable we invite your participation. We are not satisfied until sure that the problems and recommendations are fully understood. We work with you to prioritize your needs, we respect your budget and form a relationship with you for the long term.


“I received a thorough and fair assessment from Durable Slate in July 2015. After my poor 80+ year old roof made it through the snow storm in January 2016, it became clear that roof repairs could no longer be place on hold.

I contacted Durable Slate on a Wednesday and Ben, Ed, and Edwin were onsite tending to repairs on Friday. While onsite the team was extremely courteous and informative. My roof was good as new on Monday and special note to all home owners – there were no surprises on the final bill. My new roof is a true source of pride thanks to the wonderful team at Durable Slate.

Special thank you to Justin, Ben, Ed and Edwin. I would recommend Durable Slate to anyone. Keep up the good work.”

tract! Couldn’t be happier!”

“I can say, without exception, we have been delighted by every interaction with Durable. From the initial interaction with your office, we have been very impressed with your company, the quality of your work and the pricing and value of the work you performed. Your field staff was professional, highly competent and both efficient and neat in their work. I look forward to a continuing relationship with Durable so that we can keep our roof in the best condition possible.”
