A well-maintained chimney flashing (flashing) is essential for protecting your home from water damage and ensuring the longevity of your chimney. Chimney flashing is a waterproof barrier that seals the gap between your chimney and your roof, preventing water from seeping into your home. In this article, we’ll discuss the importance of the flashing, common problems, and how to maintain it.
Understanding Chimney Flashing
The flashing is typically made of metal, such as copper or lead. It’s installed in layers to create a watertight seal around the chimney. The most common types of flashing include:
- Step Flashing: This type of flashing is installed in steps around the chimney, creating a watertight seal.
- Counter Flashing: Counter flashing is installed over the step flashing to provide additional protection.
- Apron Flashing: Apron flashing is used to cover the gap between the chimney and the roof.
The Importance of The Flashing
A well-maintained flashing is crucial for protecting your home from water damage. Water damage can lead to a variety of problems, including:

- Interior Damage: Water damage can spread to your home’s interior, causing damage to walls, ceilings, and floors.
Common Flashing Problems
- Cracks and Gaps: Over time, the flashing can crack or develop gaps, allowing water to seep into your home.
