How to Fix a Roof Leak Around a Chimney
- Place the extension ladder in a stable spot and climb onto the roof.
- Inspect the chimney flashing. Clear away any leaves or dirt that might obstruct your view. Check all edges thoroughly to locate any gaps that are letting in water.
- Remove loose or deteriorated sealant with a chisel and wire brush.
- Apply fresh flashing sealant around all edges of flashing. Use the utility knife to cut a hole in the tube tip so that it produces a 1/4-inch bead of sealant.
- If any flashing was loose, apply sealant behind the loose edges.
- To secure loose flashing, use the hammer drill to attach more masonry screws to the flashing.
- Cover exposed screw heads with sealant.
- After the sealant dries, test the repair by using a garden hose to run water around the chimney for 5 minutes.
- If leaking persists, look for any gaps that you might have missed and apply more sealant.
