The answer to 'flashing leaking' is that flashing leaks are a common roofing problem that can have several causes, such as improper installation, damage, or deterioration over time. Symptoms of a flashing leak include water stains on the ceiling or walls, peeling paint, and musty odors. To fix a flashing leak, the first step is to identify the source of the leak by thoroughly inspecting the roof and flashing. This may require calling a professional roofer, as they have the expertise to properly diagnose and repair the issue.
If the problem is minor, such as a small crack or gap in the flashing, a homeowner may be able to DIY the repair by applying a high-quality sealant or caulk. However, for more complex issues, such as extensive damage or improper flashing installation, it's best to hire a licensed and experienced roofer to ensure the problem is fixed correctly and prevent further leaks or water damage.
