Roofing in Dundalk, MD

The median home in the community of Dundalk was built in 1955, older than the U.S. median of 1980 and older than the Maryland median of 1979.¹ On a roof of that vintage a contractor should check the decking before quoting - a tear-off rather than an overlay is the usual recommendation so soft sheathing is found, not buried. The stock is old by national standards: 85% of Dundalk's housing units were built before 1980 (U.S. 50%), and only 4% since 2010.¹ Rainfall is substantial: about 45 inches a year, 11 days of it an inch or more.^2,3 Where heavy-rain days are common, the quote should name the underlayment and the valley and flashing details, which is where most leaks start.

Snowfall averages about 19 inches a year.^2,3 Even light snow sits on a roof for days, so the eave membrane and gutter condition still belong on the inspection list. Summers bring about 34 days a year at or above 90°F.^2,3 Dundalk is about 3 miles from the ocean or Gulf coast in a straight line.^4,5 Near the coast, fastener grade and wind rating matter: ask for stainless or hot-dipped galvanized fasteners and for the installed wind rating of the shingle system.

Owner-occupied homes in Dundalk are older than rentals: a median build year of 1954 against 1959.¹ Where owner-occupied homes skew older, a repair-versus-replace conversation is the usual starting point rather than a like-for-like swap. Building permits in Dundalk are normally issued by the county, as this is an unincorporated community.^6,7 Any permit goes through the county, since the community is unincorporated.
