St. Mary's sits between the Potomac, the Patuxent and the Chesapeake Bay, with more than 400 miles of shoreline. Wind comes off open water from almost every direction, and it goes after shingle edges and ridge caps first.
The county's building code sets a wind design speed of 115, rates weathering as severe and requires an ice barrier underlayment. Those are the conditions a roof here is expected to survive.
Hurricane Isabel in 2003 was a federal disaster for the county, followed by Irene, the June 2012 straight-line winds, Sandy and Tropical Storm Isaias. In 2020 Isaias spun up two confirmed tornadoes here, one on a 5.3-mile path from Piney Point to Callaway.
From Navy families in Lexington Park to farms up north, the same crew does the whole roof.
Roof replacement in St. Mary's County means building to the conditions in the county code: wind off three bodies of water and an ice barrier at the eaves. Our crew tears the old roof to the deck, installs a complete GAF system and sweeps the yard for nails, after a written quote you have had time to read.

More than 80 percent of American homes carry asphalt shingles. A three-tab roof typically lasts around 20 years and architectural shingles around 30, while metal lasts 40 to 80. With nearly two in three county homes built before 2000, a lot of St. Mary's roofs are on borrowed time, especially on the exposed, waterfront side of a lot.

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.
Leonardtown is the county's only incorporated town, and it handles its own planning, zoning and building permits.
Designated historic landmarks and districts in the unincorporated county need a certificate of appropriateness for changes in design or material.
Whether a particular job needs a permit depends on the work and the address. LUGM or the town can confirm, or ask us during your inspection.
