Monsey is a hamlet in the Town of Ramapo, and it has grown quickly. The 2020 census counted 5,002 households here, up from 2,981 in 2000. That growth means a street can hold a mid-century house with its original masonry chimney next to a recently built or heavily extended home.
The two fail differently. An older brick chimney usually needs attention at its mortar joints, crown and clay flue tiles. A newer home may have a factory-built metal chimney inside a framed chase, where the usual problems are the chase cover and the flashing instead of the brick.
Homes that have been extended often have a chimney that now sits lower than a new roofline beside it. That changes how water and wind reach it, and it is a common reason an older chimney starts leaking after an addition.

What winter does to a chimney here
Monsey sits in the same weather as the rest of Rockland County. Winter temperatures cross the freezing point many times a season. Water that has soaked into brick, mortar or a cracked crown expands as it freezes, and each cycle opens the damage a little further.
The practical point is timing. A small crown crack or an open mortar joint repaired in a mild month is a modest job. The same defect left through two or three winters often becomes a rebuild above the roofline.
