About Us

Expertise | Integrity | Service
Successful companies aren't built overnight. It takes visionary leadership, a talented team and proven longevity to achieve a rock solid reputation. Managing projects of diverse size and scope, we've earned praise for our relentless focus on quality and unsurpassed service. Today, at Simpson of Maryland, we take pride in our history - delivering excellence in exterior building solutions.

Quality Craftsmanship
Founded in 2002 by two veteran contractors, Dennis Patrick and Greg Simpson, the two merged their combined experience in the construction trades. Their shared goal was to build a premier roofing and restoration company by recruiting and motivating talented crews focusing on core values: quality craftsmanship, safety, integrity and first class service. We achieved our goal to generate $1 million in revenue during the first year in operation and by 2008, our hard work and perseverance yielded $12 million. We have our customers to thank!

Today, Simpson of Maryland employs a team of experienced craftsman and professionals who receive continuous training and education, always sharpening their skills. We never stop in our quest to be the best.

Safety: A Top Priority for Building Owners and Managers
The rooftop of any building serves as its "anchor" and must endure the ravages of time and weather to provide protection, shelter and safety to both the occupants and material goods within. Our own impeccable safety record affirms our commitment to the protection of valuable life and property. To that end, Simpson of Maryland offers a full-service range of commercial exterior restoration solutions, preventing and repairing cracks, leaks and other wear and tear including:

• Roofing replacement, restoration, repair and maintenance
• Concrete repair & replacement
• Stone replacement, waterproofing
• Sealant application/specialty coatings
• Architectural sheet metal
• Preventative maintenance

So whether you want to prevent problems from happening in the first place, fix a leak or a loose shingle, or replace an entire rooftop, we promise the same level of commitment. Call us today and we promise to listen to your needs, respond to your emergency or recommend solutions.
