The answer to 'flashing damaged' is that damaged flashing is a common roofing issue that can lead to leaks and water damage. Flashing is the thin metal or plastic material used to seal roof joints, edges, and penetrations to prevent water intrusion. Common causes of flashing damage include weathering, corrosion, poor installation, and physical damage from storms or roof work.
Signs of damaged flashing include visible cracks, holes, gaps, or loosening around chimneys, vents, skylights, and roof edges. This can allow water to seep into the home, leading to interior water damage, mold growth, and structural issues. In many cases, repairing or replacing damaged flashing is a job best left to professional roofers, as improper DIY work can make the problem worse.
