The answer to 'flashing repair worn out' is that worn or damaged roof flashing needs to be repaired or replaced to prevent leaks and water damage. Flashing is the thin metal or plastic material used around chimneys, vents, and other roof penetrations to divert water away from the roof. Over time, flashing can become cracked, rusted, or loose, allowing water to seep in and cause damage to the roof deck and interior of the home.
Common symptoms of worn out flashing include visible cracks or holes, rust, and water stains or leaks around the flashed areas. Solutions may include resealing the flashing with caulk or sealant, or completely replacing the flashing if it is severely deteriorated. DIY flashing repair is possible for minor issues, but for significant damage or difficult-to-access areas, it's best to call a professional roofing contractor who can properly assess and fix the problem.
