For the past 30 years, Certified Incorporated has offered the Washington DC Metropolitan area the highest quality workmanship and unmatched level of expertise in specialty metal, shingle, slate, cedar shake, and flat roofing installation. We primarily serve the greater Washington DC area, including Maryland, Washington, D.C. and Northern Virginia.

We also specialize in synthetic slate roofs, vinyl siding, fiber cement siding, gutter, cornice and trim work.

Certified Incorporated fabricates its own sheet metal, flashings, custom gutters, standing seam metal pans, and any other roof related accessory needed for the completion of a new roof.

Although we have completed many large commercial, industrial, religious and educational projects, the majority of our work is in the installation of new & replacement roofs on residential homes.

Certified Inc. is known for its skilled craftsmen and their attention to detail. All of the professional roofers, estimators, and project managers have completed thousands of hours of training from the largest manufacturers of roofing products.

We strive to make all of our customers 100% satisfied with our work. The training and certifications that we have earned allow us to live up to this goal. We are confident that we will far exceed your expectations on your next roofing project.
