How to Fix a Roof Leak Around a Chimney

Fixing a Roof Leak Around a Chimney

Repairing a roof leak around a chimney demands immediate attention to prevent further damage. If water is coming in near your chimney, inadequate chimney flashing could be the cause. While a DIY solution might suffice, it is best to contact roofing experts for this issue. To address chimney flashing issues, follow these steps outlined for how to fix a roof leak around a chimney. Dream Home Roofers always recommends that you hire a licensed roofer so that you and your home remain safe.

Tools & Materials Needed to Fix Your Roof

Ensure your extension ladder extends at least 3 feet past the roof edge for safety. Opt for polyurethane flashing sealant for its ability to expand and contract with temperature changes. If your roof has a steep pitch, employ a roof safety harness for protection.

  • Extension ladder
  • Roof safety harness
  • Work gloves
  • Wire brush
  • Chisel
  • Hammer drill
  • Masonry screws
  • Caulking gun
  • Polyurethane flashing sealant
  • Utility knife
  • Garden hose

Step by Step Instructions to Fix the Leak:

  1. Position the extension ladder securely and ascend to the roof.
  2. Examine the chimney flashing, ensuring no debris obstructs your view. Thoroughly check all edges for gaps allowing water ingress.
  3. Eliminate any loose or deteriorated sealant using a chisel and wire brush.
  4. Apply fresh flashing sealant along all flashing edges. Modify the tube tip with a utility knife to produce a 1/4-inch sealant bead.
  5. If any flashing is loose, apply sealant beneath the loose sections.
  6. Use a hammer drill to affix additional masonry screws to secure loose flashing.
  7. Seal exposed screw heads with sealant.
  8. Once the sealant sets, test the repair by running water around the chimney with a garden hose for 5 minutes.
  9. If leakage persists, search for overlooked gaps and apply additional sealant.
