Knowing how to repair a clay tile roof flashing can save your home from extreme water damage. The most common locations for flashing are valleys, roof penetrations, eaves, skylights, ridges and chimneys, and are used to waterproof the roof. Flashing is the last defensive stop before water penetration.

In order to effectively repair, the flashing must be replaced. The chimney and roof are exposed to all the elements and a lot of wear and tear occurs over time.

Use caulking to attach flashing to the pipe. The flashing should be taller than the pipe. Use the straight-cutting tin snips and cut the top above the old pipe. Bend it into the top of the pipe. This ensures a water tight seal.

Step 5 - Replace Roof Tiles
