“I’ve been working with Walls Contracting for over 25 years; I have learned to trust their care for the details and not to cut corners. I place them on my bidders list for every roofing project and they help me trouble shoot repairs to our roofing problems.”

– Michael Griffin; Facilities Manager, American University


I have worked with the James R. Walls Contracting Co., Inc. on over 100 roofing and waterproofing restoration projects over the last 25 years. The projects have ranged from targeted leak repairs and catch-up maintenance to full roofing and waterproofing system replacements. Their sheet metal work is some of the best in the Washington, DC area, and their attention to detail makes them the ideal company to take on the most complex roofing and waterproofing projects. I regularly recommend them to building owners, property managers and construction managers who call for referrals. They are honest, charge fair prices and consistently deliver outstanding quality.

-David DiQuollo; Principal Seal Engineering


Whether the project has been small or large, we appreciate that we can rely on Walls to provide well trained, knowledgeable and highly skilled personnel with an eye for detail and a commitment to quality. We thank you for employing some of the most skilled and accomplished roofing and sheet metal mechanics in the entire Washington, D.C. metro area. Your management and those mechanics really elevate your company above most other roofing contractors.
