Asphalt shingles are the most common and most affordable type of shingle found in the DC metro area. They are composition shingles, meaning they are a combination of asphalt, paper, crushed rock, and fiberglass compressed into a highly durable shingle strip. Asphalt shingles are light-weight and can be very cost-effective. Many choose these shingles not only for their lower cost, but also for their wide variety of styles and colors, enabling you to reduce costs without compromising on aesthetics.

When you choose these shingles for your roofing work with us, you will be working with a Certainteed Select ShingleMaster: the top 1% of roofing professionals according to the manufacturer. You will have full confidence in your roof installation knowing it was done by one of the best roofing contractors in the nation.


Cedar shakes and shingles have been used on roofs for hundreds of years and have definitively proven their durability in all climates. They contain oils that make them naturally rot- and insect-resistant, which extends their lifespan significantly. However, their longevity is ultimately determined by the quality of the roof construction. There must be adequate ventilation to avoid the build-up of heat, moisture, and ice damming. We recommend installing pressure-treated shakes in Maryland due to the humidity.

Certified Roofing is a member of the Cedar Shake & Shingle Bureau, which means we strictly adhere to the best practices set forth by this major authority in cedar product installation. This credential enables us to offer the best cedar shake warranties in the roofing business. Roofers who are not an approved installer will not be able to offer a material warranty from the Bureau.


Flat roofing, commonly referred to as low slope roofing, is often found on row houses, office buildings, carports, and porch roofs throughout the DC metro area. We have the expertise to install the following flat roof materials:

Our roofers have been trained by the major manufacturers of flat roof products such as Firestone, Mulehide, and Sarnafil. We recognize that flat and low slope roofing installation requires extra knowledge and care, and we have taken every step to ensure that we offer unparalleled service to our valued customers.
