If you have a leaky chimney, a number of problems could be to blame. Because your chimney is constantly exposed to rain, snow, and other weather, it’s vital to have it waterproofed. Failing to waterproof your chimney is one major source of chimney leaks and, consequently, water damage.
Alternatively, if you have a chimney leak, the issue could be your chimney flashing—the metal that joins the roof to the chimney. If you have water staining on your ceiling near your chimney or even running down the walls, it’s possible that your chimney needs re-flashing.
