Thumping and scratching on the roof in the middle of the night is almost always a raccoon. They’re strong climbers, and once one finds its way up, it’s a short step to your chimney, vents, or attic. Here’s how to confirm it’s a raccoon and what to do about it.
Why they’re up there
Raccoons get on roofs the same way they get anywhere: overhanging branches, downspouts, and rough siding. Once up, they’re either passing through to a chimney or attic, or poking around for food in the gutters. A raccoon on the roof is usually a sign it’s already found, or is looking for, a way in.
What raccoon noise sounds like
It’s heavy and slow, a raccoon weighs a lot more than a squirrel, so the thumps are louder and spaced out. You’ll hear it at night, often in the early morning hours. If the noise is only during the day, it’s more likely squirrels or birds.
Look for droppings in the gutters or near the chimney, torn vent covers, and shingles or flashing that have been clawed at.
How to get them off
Don’t corner or chase a raccoon on a roof, a scared one can fall or get aggressive. Shine a light or make noise from a safe window to nudge it along. That’s temporary though. If it’s already in the attic, have a pro put in a one-way door and seal the entry only after it’s out. See my raccoon cage traps guide for the trapping side. If you’re not sure how it’s getting up, or there are babies involved, call someone.
Keep them from coming back
- Trim branches back from the roof and chimney.
- Cap the chimney with fine mesh.
- Cover vents with hardware cloth.
- Lock down trash and remove food from the yard, starting with raccoon-proof garbage cans.
Frequently Asked Questions
Yes. They tear shingles, claw at vents and flashing, and rip open chimney caps looking for a way in. The damage gets worse the longer they use the route.
Raccoons are nocturnal, so the thumping and scratching after dark is exactly when you’d hear them.
Yes. They can lift shingles, force vents, and squeeze through gaps along the roofline. Roof access should be treated as an attic risk.
No. Climbing on a roof at night to confront a wild animal is how people get hurt. Use light or noise from a safe spot, or call a pro.
