The answer to 'how often to replace flashing repair' is that flashing should typically be inspected and repaired or replaced every 5-10 years, or whenever there are signs of damage or deterioration. Flashing is the metal or plastic material used around chimneys, vents, and other roof penetrations to prevent water leaks. Over time, flashing can become cracked, corroded, or loose, allowing water to seep into the home and cause damage.
It's important to have a professional roofing contractor inspect your flashing regularly and make any necessary repairs or replacements. Catching issues early can help prevent costly water damage down the line. Some homeowners may be able to perform minor flashing repairs themselves, but for more extensive work or if you're unsure, it's best to hire a qualified roofer.
