Cracked or spalling brick on a chimney happens for the same reasons it happens elsewhere on a home: water gets into the brick, freezes, and causes the surface to crack and flake. Chimneys are particularly exposed to weather given their height and position on a roofline, which is part of why chimney brick often shows wear before other brickwork on the same house.

Deteriorated mortar joints on a chimney follow the same pattern as tuckpointing needs elsewhere, but the consequences of ignoring it are often more serious given a chimney's exposure and the fact that it houses an active flue in many cases. Failing mortar on a chimney lets water in more readily, accelerating brick damage and, in more advanced cases, affecting the structural stability of the chimney itself.

A damaged or missing chimney cap is a smaller issue that causes bigger problems if left unaddressed. Without a proper cap, rain and snow get directly into the chimney flue, leading to water damage inside the chimney structure and, in homes with a fireplace, potential damage to the firebox and flue lining as well.

Flashing issues, where the metal seal between the chimney and roof has failed, are a common source of water intrusion that often gets misdiagnosed as a roofing problem rather than a masonry issue, since the water damage often shows up on ceilings or walls near the chimney rather than on the chimney itself.

Most chimney repair issues are not emergencies, but they also don't improve on their own. A chimney with cracked mortar or minor brick damage can typically wait for a scheduled repair rather than requiring immediate emergency service, though the longer repair is delayed, the more extensive and costly the eventual fix tends to become.

Leaning or visibly separating chimneys are the exception, and these do warrant prompt attention, since they can indicate structural issues that pose a safety risk.
