What should I do immediately after discovering a roof leak?

Water moves fast and causes damage you can't see. Inside, place buckets under the drip and move furniture away. If water is running along walls or beams toward the electrical panel, stop it with towels and buckets positioned to redirect flow.

If the leak is actively running into insulation or framing, cut a small hole in the drywall below the leak to let water drain into a bucket rather than soaking into the structure. This prevents mold and rot that cost far more to fix later.

Temporary roof protection

From above, a temporary tarp over the damaged area stops new water from entering while you wait for a contractor. Weight it down safely. This is not permanent but buys time if weather is mild. Don't climb on a wet roof.

When to call emergency services

If the leak is large, multiple areas are affected, or a ceiling is sagging, call a roofer same day. A single small leak can wait 24 to 48 hours. Document what you see with photos for your insurance claim and the contractor estimate.
