The answer to 'why is my flashing damaged' is that flashing can become damaged over time due to factors like weathering, improper installation, or physical damage. Common symptoms include cracks, holes, or separation from the roof or wall. Solutions may include repairing or replacing the flashing, which is best done by a professional roofing contractor.
Flashing is the thin metal or plastic material used around roof penetrations, edges, and transitions to prevent water leaks. It can become damaged from exposure to sun, rain, ice, and physical impacts like falling branches. Improper installation, such as not sealing the flashing correctly, can also lead to damage over time. If the flashing is cracked, loose, or no longer creating a watertight seal, it needs to be repaired or replaced to prevent roof leaks.
