What Is Chimney Flashing and Why Is It Important?

Our friends on the East coast are suffering through the consequences of Hurricane Irene. Key ingredients of a hurricane include high-powered winds and violent sheets of rain, which can be detrimental to your chimney. Your best defense for extreme weather is to make sure your chimney flashing is solid and secure.

Chimney flashing is what seals the space between your roof and your chimney. High quality chimney flashing is critical because it keeps rain and the water from melting snow from leaking into your house. The corners of your chimney are particular trouble spots. Unmonitored, these leaks can result in significant damage to the ceilings and walls of your home.

We’re no strangers to severe weather such as tornados and snowstorms here in Indiana. Therefore, it’s important to consider the last time you had someone check the flashing on your chimney. Below are some common reasons your flashing may need to be replaced:

• The flashing is missing because of erosion or the long-term effects of weather may have worn it away.
• You’re having shingles on your roof replaced.
• The flashing is rusted – most flashing is made of aluminum, galvanized steel, or copper.
• The flashing has been covered up with roofing tar, diminishing its effectiveness.
• Your home has settled or shifted – most chimneys aren’t attached to the frame of your house – which opens the door for leaks.
