If you have damp patches on your ceiling after heavy rain, it is likely that water is infiltrating your roof or attic space. Here are some possible reasons why:
- Roof leaks: Heavy rain can cause water to seep through gaps or cracks in your roof, which can then infiltrate your ceiling and cause damp patches.
- Damaged flashing: Flashing is a thin piece of metal that is installed around the edges of the roof, as well as around chimneys, skylights, and other roof penetrations. If the flashing becomes damaged or corroded, it can allow water to seep into the roof.
- Clogged gutters or downspouts: If your gutters and downspouts are clogged with leaves, debris, or other material, water can overflow and seep into the roof.
- Poor ventilation: Poor ventilation can cause moisture to build up in the attic or roof space, leading to mold growth and damage to the roofing material.
It’s important to identify and address the source of the leak as soon as possible to prevent further damage to your roof and your home. If you are unsure about how to identify or fix the issue, it’s best to consult a roofing professional for assistance.
