Chimney flashing is a crucial component of any roofing system that includes a chimney. Flashing is designed to prevent water from seeping into the roof and causing damage, and chimney flashing is specifically designed to protect the area around a chimney. In this blog post, we will discuss what chimney flashing is, why it is important, and the different types of chimney flashing available.
What is Chimney Flashing?
Chimney flashing is a type of metal flashing that is installed around the base of a chimney to prevent water from seeping into the roof. Flashing is typically made of aluminum or galvanized steel and is installed over a layer of roofing underlayment.
Why is Chimney Flashing Important?
Chimney flashing is important because it helps prevent water from seeping into the roof around the chimney. Water can cause significant damage to a roof, including rotting wood, mold growth, and water stains. By installing chimney flashing, you can help protect your roof from water damage and prolong its lifespan.
Types of Chimney Flashing
There are several types of chimney flashing available, including:
- Step Flashing – Step flashing is a type of flashing that is installed in a step pattern along the side of a chimney. Step flashing is typically installed underneath the shingles and is designed to direct water away from the chimney and onto the roof.
- Continuous Flashing – Continuous flashing is a type of flashing that is installed in a continuous strip around the base of the chimney. This type of flashing is typically used on flat roofs or roofs with a low slope.
- Counter Flashing – Counter flashing is a type of flashing that is installed over the step flashing to provide an additional layer of protection. Counter flashing is typically made of metal and is designed to blend in with the masonry around the chimney.
- Prefabricated Flashing – Prefabricated flashing is a type of flashing that is pre-made to fit a specific chimney size and shape. This type of flashing is easy to install and can provide a custom fit for your chimney.
