Baltimore rowhomes and older colonials feature tall brick chimneys that rise three to five feet above the roof line. These chimneys create large water diversion zones that require properly engineered crickets. When a chimney is wider than 30 inches, building code requires a cricket to prevent water from pooling on the upslope side. Baltimore's spring thunderstorms drop an inch of rain in an hour. Without a functional cricket, that water has nowhere to go. It sits, seeps under shingles, and rots your roof deck.
A Plus Roofing Baltimore has worked on every style of chimney common to the area. We know how to flash against deteriorating mortar joints, how to integrate crickets with slate roofs in Roland Park, and how to handle the tight working conditions on Federal Hill rowhomes. We pull permits when required and coordinate with city inspectors. You get a roofer who understands local building culture and has relationships with the suppliers who stock the right materials.
