Roofing company in Lutherville-Timonium, MD

In 21093 the age of your house tells us more about your roof than the shingle on top of it does.

Most of Lutherville-Timonium is mid-century. About 38% of all homes in 21093 were built in the 1950s and 1960s, and in the Lutherville census area on its own, nearly half went up in the 1950s. Timonium is much the same, with roughly six homes in ten from those two decades. Those are detached houses on their third roof or so by now, and the useful question is what earlier crews left underneath, not what is on top. Reused flashing and decking that was covered rather than replaced are what we photograph during a roof inspection.

Across I-83, Mays Chapel belongs to a different era. About 58% of its homes were built in the 1980s and 1990s, and roughly one in four is attached rather than detached. That is mostly a first or second replacement on a builder-installed roof, where the decking is usually still sound and the attention goes to attic ventilation and to the detail where one townhouse roof meets the next. A leak at that junction is your neighbor’s problem as well as yours.

Then there is Historic Lutherville. The village was laid out in 1852 around the Lutherville Female Seminary, and most of its houses predate World War I, in Gothic Revival, Late Victorian and Colonial Revival styles. The larger district is on the National Register, and a smaller Baltimore County historic district, created in 1987, sits inside it. The county’s Landmarks Preservation Commission reviews and approves proposed changes to properties in county districts, so a roof there is not purely a matter of what you like. We establish whether your address is inside the county district before we talk about material.

The older houses bring their own roofing problems. Victorian and Gothic Revival roof lines are steeper and more cut up than a 1950s rambler, with more valleys and more places where roof meets wall. That is where the flashing does the real work, and it is usually where an old roof lets water in first.

Permit requirements come from Baltimore County and depend on whether the work is like-for-like or structural. We confirm what your address needs before work starts.

Housing figures are from the U.S. Census Bureau’s American Community Survey (2020-2024 5-year) for ZIP 21093 and the Lutherville, Timonium and Mays Chapel census areas.
