Chimney flashing is associated with leaks more often than any other chimney component.

Chimney flashing is especially challenging to install correctly.
What is Chimney Flashing?
The sheet metal at the base of chimneys is the chimney flashing. The purpose of flashing is to create a watertight seal between the chimney and the roof. Flashing is placed under the roof covering, such as shingles, and then the flashing goes upward, laying flush against the four sides of the chimney walls.
Stainless steel, aluminum, and copper are the typical materials used for chimney flashing. Aluminum is the least expensive and most prone to rust. Copper and stainless steel are far more long-lasting, and copper is the most expensive and has the most decorative appeal.
The most vulnerable part of chimney flashing is at the top, where it is tricky to install correctly. Urethane caulking is typically used to ensure a watertight bond. It’s important that the technicians installing chimney flashing on your home have experience.
What Type of Chimney Flashing Repair is Needed?
A chimney leak can occur when chimney flashing that’s against the roof has a rusty nail. If there isn’t a watertight seal at the top of the flashing, water runs down into the chimney system and can cause damage in a home’s interior. Not only can flashing rust, it can become loose or cracked due to extreme weather or as a result of common wear and tear. Faulty flashing repair or installation often result in the need for further repair.
Leaky flashing can cause wood rot, mold, drywall damage, damage of roof structures and deterioration of masonry due to water intrusion.
How to Help Prevent Damage from Chimney Flashing Leaks
Homeowners can periodically check in their attic to make sure a chimney leak isn’t causing roof damage. Another preventative measure is to schedule annual chimney inspections. All of the leading fire safety organizations agree that annual chimney inspections are important. This includes the National Fire Protection Association (NFPA), Chimney Safety Institute of America (CSIA), and the International Masonry Institute (IMI).
One of the many benefits of a chimney inspection is that the flashing is carefully checked. Four Seasons Fireplace & Chimney offers expert chimney inspections and chimney flashing repair for homeowners in Knoxville as well as nearby communities of Maryville, Jefferson City, Gatlinburg, Oak Ridge, Morristown, and Pigeon Forge.
Oftentimes, our technicians find that the caulking on chimney flashing is developing gaps, and fresh caulking is added. New flashing may be required, if there is corrosion or part of the metal flashing is missing.
