Flashing and chimneys are an integral part of your home. Make sure to install new chimney flashing when it is missing, rusted, falling out, or covered with lots of roofing tar.

Flashing is located where your chimney and roof meet. It is intended to provide a waterproof barrier that shields your chimney and roof from moisture infiltration.

Depending on variables like where you reside, the size and form of your chimney, the materials used, and other criteria, chimney flashing may last over 30 years when it is put correctly.
