The answer to 'flashing worn out' is that worn or damaged flashing is a common roofing issue that can lead to leaks and water damage if not addressed. Flashing is the thin metal or plastic material used around roof features like chimneys, vents, and edges to prevent water intrusion. Over time, flashing can become cracked, loose, or corroded, allowing water to seep in.
Some common causes of worn flashing include exposure to the elements, poor installation, and age. Symptoms include visible cracks, gaps, or rust. Solutions may involve repairing or replacing the flashing, which is a task best left to professional roofers unless it's a very minor issue. Attempting DIY flashing repairs without proper experience can lead to further damage, so it's generally recommended to hire a qualified roofing contractor for this type of work.
