Immediate Steps to Take When Your Roof Starts Leaking

1. Contain the Leak

Prevent further interior damage by placing buckets, towels, or plastic containers under the dripping water. If the leak is spreading, use multiple containers and cover furniture with plastic sheets to protect against water stains.

2. Identify the Source

Leaks can originate from damaged shingles, clogged gutters, broken flashing, or worn-out sealant around vents and chimneys. If it’s safe, inspect your attic for wet insulation, water stains, or mold growth to help locate the leak’s source.

3. Minimize Interior Damage

If water is pooling in your ceiling, use a screwdriver to puncture a small hole where the water is collecting. This allows it to drain into a bucket instead of spreading and causing ceiling collapse.

4. Temporarily Cover the Leak

If the weather allows, apply a tarp over the affected area to prevent more water from entering your home. This is a temporary solution until a professional can assess and repair the damage.
