The answer to 'when to replace flashing repair' is that flashing should typically be replaced every 10-15 years, or sooner if it becomes damaged, cracked, or starts to pull away from the roof. Flashing is the metal or plastic material used around roof penetrations, edges, and joints to prevent leaks. Over time, flashing can deteriorate due to exposure to the elements, leading to potential water intrusion and roof damage if not addressed.
It's important to inspect your flashing regularly, especially after severe weather, and have it repaired or replaced by a professional roofing contractor if needed. Catching and fixing flashing issues early can help prevent more extensive and costly roof repairs down the line.
