A leaky chimney can cause severe damage to your home, leading to mold growth, weakened structures, and costly repairs. One of the primary culprits behind chimney leaks is improperly sealed flashing. If you want to safeguard your home against water infiltration, knowing how to seal chimney flashing correctly is essential.
In this guide, All Point Roofing & Chimney shares expert tips on sealing chimney flashing and preventing leaks for years to come.
What is Chimney Flashing?
Chimney flashing is a metal barrier installed around the base of your chimney to prevent water from seeping into your home. Over time, exposure to harsh weather conditions can cause flashing to deteriorate, leading to leaks.
Signs of a Leaky Chimney Flashing
Before sealing chimney flashing, check for these common signs of leaks:
- Water stains on ceilings or walls near the chimney
- Dampness or mold in the attic
- Rusted or loose flashing
- Dripping sounds during or after rain
How to Seal Chimney Flashing in 5 Simple Steps
1. Gather Your Materials
You’ll need the following tools and materials:
- Roofing cement or high-quality silicone sealant
- Wire brush
- Putty knife
- Ladder and safety gear
- Caulking gun
2. Inspect and Clean the Flashing
Remove any debris or old, loose sealant using a wire brush. Ensure the surface is dry before applying new sealant for better adhesion.
3. Apply Roofing Cement or Sealant
Using a putty knife or caulking gun, apply a generous layer of roofing cement or silicone sealant along the edges where the flashing meets the chimney and roof.
4. Smooth and Secure the Sealant
Spread the sealant evenly, ensuring all gaps and cracks are thoroughly covered. Press it firmly into place to create a watertight seal.
5. Inspect and Maintain Regularly
Check your chimney flashing at least once a year, especially before and after the winter season. If you notice any cracks or peeling, reapply sealant as needed.
When to Call a Professional
While sealing chimney flashing is a manageable DIY task, some situations require professional help. If your flashing is severely damaged, rusted, or improperly installed, it’s best to contact an expert like All Point Roofing & Chimney to ensure a durable and reliable repair.

Properly sealed chimney flashing is crucial in preventing leaks and maintaining the integrity of your home. By following these steps, you can effectively seal your chimney flashing and avoid costly water damage.
