The answer to 'how often to replace flashing repair' is that flashing should typically be replaced every 10-20 years, or whenever it shows signs of wear and damage. Flashing is the metal or rubberized material installed around chimneys, skylights, and other roof penetrations to prevent leaks. Over time, flashing can corrode, crack, or become dislodged, allowing water to enter the home.
Homeowners should inspect their flashing regularly and have it repaired or replaced as needed. Catching issues early can help prevent costly water damage and roof leaks. If the flashing is in poor condition, it's best to have a professional roofer replace it to ensure a proper, long-lasting installation.
