St. Mary's County has more than 400 miles of shoreline between the Potomac, the Patuxent and the Chesapeake Bay, and wind off the water hits shingle edges and ridge caps first. We install complete GAF roof systems with proper ventilation, correct flashing and ice-and-water protection in the valleys, the details a waterfront county demands.
The St. Mary's County code calls for a wind design speed of 115, rates weathering as severe and requires an ice barrier underlayment. Our own crew builds to those conditions, and the person who inspects your roof writes the quote and runs the job.
From Isabel in 2003 to Isaias in 2020, St. Mary's County has a long list of major storms, and Isaias spun up two confirmed tornadoes here. Because we are based in Mechanicsville, our 24-hour emergency storm response is a short drive away, and we stay with you through the insurance claim.
One local crew and one point of contact, from Navy family homes in Lexington Park to farm properties up north.
When it is time for a new roof, you want one built for this county's wind and ice. Our roof replacement in St. Mary's County tears off to the deck, installs a complete GAF system with an ice barrier at the eaves and ends with a nail sweep, all after a written quote you can read at your own pace.

More than 80 percent of American homes wear asphalt shingles. Three-tab usually lasts about 20 years, architectural about 30 and metal 40 to 80. With nearly two in three county homes built before 2000, plenty of St. Mary's County roofs are running out of time. A free inspection from a local roofer tells you where yours stands before a storm makes the decision for you.

Outside Leonardtown, building permits come from the county Department of Land Use and Growth Management (LUGM). The county code adopts the 2021 International Residential Code.
