Roof replacement in Catonsville, MD

Most Catonsville houses are detached with a pitched roof, so the replacement is usually shingle. What differs is what sits underneath.

Westview Park is roughly 1,800 homes built between 1955 and 1967, and the 1950s were the biggest building decade in 21228 by some way. Those roofs are on their second or third replacement. A full tear-off shows whether earlier crews replaced soft decking or simply covered it, and whether the flashing at chimneys and walls was ever renewed. We photograph the bare deck, and you see any sheet before it is replaced, at the per-sheet price written on the quote.

Woodbridge Valley, about 1,000 units from the 1970s north of Baltimore National Pike, raises a different pair of questions: ventilation and decking. The replacement includes ridge ventilation sized to the roof and a check of the soffit intake that feeds it, because a new roof over the same airflow ages the same way. Where a townhouse row or a low-slope rear addition sits below shingle pitch, that section gets a membrane and is priced on its own line.

In Old Catonsville the houses run from Queen Anne to Tudor Revival and Craftsman, with dormers, valleys and steep sections that carry a lot of flashing. Before a heavier material goes back on a pre-1940 frame, the structure gets checked rather than assumed. The district is on the National Register, which is not the same as local designation, so we check what applies to your address first. Permits come from Baltimore County, though some Catonsville mail uses 21229, which is mostly Baltimore City, and we confirm which applies.
