Thumping and scratching noises on your roof at night almost certainly mean raccoons are on your roof. Raccoons (Procyon lotor) are excellent climbers that use trees, downspouts, and siding to access roofs. Once there, they may rip off shingles, damage vents, and enter your attic. This guide covers how to identify raccoon activity on your roof, remove them safely, and prevent re-entry.
Key Takeaways
- Raccoons on the roof at night are likely foraging, seeking shelter, or trying to access the attic.
- Trim tree branches at least 8 feet from the roofline to remove their primary access route.
- Install a chimney cap and cover all vents with 1/4 inch hardware cloth.
- Use a one-way exclusion door if raccoons have already entered the attic.

Signs of Raccoons on Your Roof
- Thumping and scratching sounds at night, especially near the roofline or chimney
- Damaged shingles that have been ripped up or displaced
- Droppings on the roof, deck, or patio below roof access points
- Damaged vent covers that have been pushed in or chewed
- Paw prints on siding, downspouts, or windows near the roof
- Noises in the attic after dark, indicating they have entered through the roof
Why Raccoons Go on Roofs
Raccoons access roofs for several reasons. Understanding their motivation helps you choose the right deterrent:
- Seeking shelter: Raccoons look for warm, dark spaces to nest. Uncapped chimneys, damaged soffits, and loose vents are inviting entry points.
- Foraging: Raccoons may be attracted to fruit trees, bird feeders, or garbage near the house.
- Escape from predators: Roofs provide a safe elevated retreat from dogs, coyotes, and other threats.
- Travel route: Raccoons use roofs as pathways between trees and food sources.
How to Remove Raccoons From Your Roof
- Identify the access point. Inspect the roofline for damaged soffits, loose vents, or gaps where the roof meets the siding. Raccoons typically use the same entry point repeatedly.
- Remove attractants. Trim tree branches, secure garbage cans, and remove bird feeders near the house. Eliminating the reason they visit reduces roof activity.
- Install a one-way exclusion door if raccoons have entered the attic. Place it over the entry point. The raccoon can exit but cannot re-enter.
- Use motion-activated deterrents. Place a motion-activated sprinkler or light on the roof near the entry point. Raccoons are neophobic and will avoid areas with sudden stimuli.
- Seal all entry points permanently. Once the raccoon is gone, seal every gap with 1/4 inch hardware cloth and galvanized steel flashing. Install a chimney cap with 1/4 inch mesh.

Frequently Asked Questions
Do raccoons sleep on roofs?
Yes. Raccoons are nocturnal and may sleep on roofs during the day, especially on warm, flat surfaces. They prefer sheltered spots like the area behind a chimney or under solar panels. If a raccoon sleeps on your roof regularly, it likely has easy access from nearby trees.
How do raccoons get on the roof?
Raccoons climb trees, downspouts, vines, and siding to reach roofs. They can also jump from overhanging branches. Their sharp claws and strong hind legs make them excellent climbers. Installing downspout guards and trimming trees removes their primary access routes.
Can raccoons damage roof shingles?
Yes. Raccoons can rip up asphalt shingles, especially at the edges and corners, to access the attic or create a nesting spot. They may also damage flashing around chimneys and vents. Repair damaged shingles promptly to prevent water damage and re-entry.
What noise do raccoons make on roofs?
Raccoons produce thumping, scratching, and shuffling sounds that are heavier than squirrel noises. You may also hear chattering, hissing, or growling if multiple raccoons are present. The sounds are most noticeable at night when raccoons are active.
The Bottom Line
Raccoons on your roof are a clear sign that they have found an access route to your home. Trim tree branches, install chimney caps, and cover all vents with 1/4 inch hardware cloth. If raccoons have already entered the attic, use a one-way exclusion door to evict them safely. Prompt action prevents expensive roof damage and keeps raccoons from establishing a den in your attic.
