The answer to 'why is my flashing cracked' is that cracked flashing is a common roofing issue often caused by age, wear and tear, or improper installation. Flashing is the thin metal or plastic material used to seal the joints and gaps around roof features like chimneys, skylights, and vents to prevent leaks. Over time, the flashing can become brittle, crack, or pull away from the roof, allowing water to seep in and damage the underlying structure.
Some common symptoms of cracked flashing include visible cracks or gaps, water stains on the ceiling or walls, and mold or mildew growth. To fix cracked flashing, the affected areas will need to be repaired or replaced. This may be a DIY project for homeowners with some roofing experience, but for more extensive damage or if you're unsure, it's best to call in a professional roofing contractor to assess and address the issue properly.
