There could be several reasons why your roof is leaking in heavy rain. Here are some common causes:
- 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.
- Cracked or missing shingles: If your roof has shingles, they can become damaged or dislodged during heavy rain or wind, leaving gaps where water can enter.
- 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.
- Poorly installed or damaged roofing material: If the roofing material is not installed properly, or if it is damaged or deteriorating, it can allow water to penetrate the roof.
- Inadequate 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.
