The answer to 'why is my flashing' is that the flashing around your roof may be damaged, worn, or improperly installed. Flashing is the metal or plastic material used to seal joints and transitions on your roof, such as around chimneys, vents, and the roof's edges. Common issues with flashing include cracks, corrosion, and gaps that can allow water to leak into your home.
Some key signs that your flashing needs attention include water stains on your ceilings or walls, mold growth, and visible damage to the flashing itself. Addressing flashing problems promptly is important to prevent further water damage and costly repairs. While minor flashing issues may be a DIY project, it's generally best to have a professional roofer inspect and repair the flashing to ensure it's properly sealed and installed.
