Is it normal for chimney to leak during heavy rain?

Chimney leaks are a common problem during the summertime, especially after periods of heavy rain.

It is important to keep your chimney and home in good condition by regularly inspecting and cleaning it. Rain and moisture can cause damage to the mortar and bricks, so it is important to keep the area dry. Additionally, moisture can damage dampers or crack the flue.
