What is Chimney Flashing?
Chimney flashing is a crucial waterproofing component installed at the base of your chimney where it meets the roof. It consists of thin pieces of metal—typically copper, aluminum, or galvanized steel—that create a barrier to prevent water from seeping into the joints between the chimney and the roof. Properly installed flashing directs water away from these seams and into the gutters, effectively protecting your home from leaks and water damage.
Types of Chimney Flashing
- Step Flashing: Installed in a step pattern along the roof slope. Used where the roof intersects the chimney.
- Counter Flashing: Installed over the step flashing. Secured into the masonry of the chimney.
- Base Flashing: Placed around the base of the chimney. Works in conjunction with step flashing.
- Cap Flashing: Covers the upper edges of step and counter flashing. Provides an additional layer of protection.
Why Chimney Flashing is Important
Chimney flashing is vital for several reasons:
- Prevents Water Damage: Protects the structural integrity of your home by preventing water from seeping into the roof and walls.
- Prevents Mold and Mildew: Stops water infiltration that can lead to mold and mildew growth, which can cause health issues.
- Maintains Chimney Integrity: Protects the masonry of the chimney from deteriorating due to moisture.
Signs of Chimney Flashing Damage
Knowing the signs of chimney flashing damage can save you from costly repairs down the line. Here are some indicators to watch for:
- Water Stains on Ceilings and Walls: Look for discoloration or water marks, especially near the chimney.
- Leaking in the Attic: Check for leaks in the attic, which can indicate flashing issues.
- Visible Rust or Corrosion: Inspect the flashing for any signs of rust or corrosion.
- Cracked or Deteriorating Mortar: Examine the mortar around the chimney for cracks or signs of wear.
- Damaged Shingles Around the Chimney: Shingles that are warped or missing near the chimney may indicate flashing problems.

When to Replace Chimney Flashing
Sometimes, repair isn’t enough, and replacement is necessary. Here are some scenarios where replacing the flashing is advised:
- Extensive Rust or Corrosion: If most of the flashing is rusted or corroded, replacement is the best option.
