"These guys are the best! They seriously care about their customers and really strive to make sure they deliver a great product. They were on time, quick, and clean. My new roof looks fantastic, and we are really glad we went with this local company. Buying a roof is not a "fun" expense, but I really feel like we got our money's worth: a quality new roof in 1 day, and then new trim capping the next day. They even installed new bathroom exhaust vents and HVAC exhausts. Our house looks brand new. You might get a cheaper rate elsewhere, but these guys do not skimp on quality of product, 50-year warranty, or craftsmanship. They even come back to inspect and follow up to make sure we are completely happy with the services provided! Talk about great customer service! The whole experience was so easy. The salesman/inspector was not pushy, and provided a very reasonable quote for what we needed. They also replaced all our rotted wood in the roof/trim."

"I just had my roof replaced by Home Genius Exteriors, and I couldn’t be happier. The initial presentation and inspection were phenomenal — super detailed, honest, and easy to understand. They kept that same level of professionalism all the way through the project. Great experience overall. The installation crew arrived right on time, worked tirelessly, and completed my entire roof replacement in just one day. After finishing, they thoroughly inspected and cleaned the area—front, back, and even my neighbor’s property. The workmanship was outstanding, and their customer service was honest and straightforward. Pricing was fair, and the overall experience exceeded my expectations. If you need roof repairs or a full replacement, Home Genius Exteriors is the company to call. I highly recommend them."

"The entire process went very well. The team at JDH is excellent, from their sales guys, to on site managers, to individual workers. All are professional and courteous and take their time to do it right. We've had a few scheduling hic-ups throughout the process, but overall they've been excellent from start to finish. Most importantly, my new roof and skylights look top notch, and will last a lifetime!"

"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."

FAQs for flat, foam, or single ply roofing installation and replacement projects in Severn, MD

Many roofing pros point to PVC as the top performer on flat roofs thanks to its tough seams and long-term waterproofing. A properly installed PVC membrane can last 30 years or more, resisting ponding water and harsh weather with ease. You will pay more up front than you would for EPDM, but the added durability often translates into fewer repairs and a lower cost per year of service.

Yes, a rubber roof is an environmentally friendly choice. Most rubber membranes contain recycled content and can reflect heat, which helps trim cooling bills in hot weather. Manufacturing has a lighter footprint than many traditional materials, and the long lifespan means fewer tear-offs headed to the landfill. If sustainability is a priority, ask your roofer about brands that carry third-party eco-certifications and confirm they meet local environmental standards.
