What is making noise in my roof at night?
TL;DR — Quick Answer
Noises coming from your roof may be caused by rats, possums, birds, or normal roof movement. Scratching and scurrying sounds at night often indicate rodents, while heavier thumping around sunrise or sunset may suggest possums. Identifying when the noise occurs can help determine the cause
What Causes Strange Noises In Your Sydney Roof?
Hearing bumps, scratches or thumps above your ceiling is incredibly common in Sydney homes. It’s easy to wonder if it’s just the house settling — or something living up there.
Research from the Australian Museum shows over 60% of Sydney suburban homes experience wildlife roof visits each year, especially near bushland areas [1].

How Do You Tell What Is Making Noise In Your Roof?
The time of day you hear sounds tells you almost everything. Here’s how to identify common culprits:
Early Morning Noises: Birds Nesting
Chirping, light scratching or rustling starting before sunrise almost always means birds. They seek warm, sheltered roof voids to build nests and raise chicks.
Bird nests in roofs carry risks: 30% of nesting sites develop bird mite infestations that spread into living areas once chicks leave [2].
Sunrise & Sunset Noises: Possums
Loud thumping, heavy walking, hissing or grunting at dusk or dawn points to possums. They use roof spaces as safe dens, and can be surprisingly loud for their size.
Important: Possums are fully protected under NSW National Parks and Wildlife Act 1974 — harming or trapping them without a licence carries fines up to $11,000 [3].
All-Night Noises: Rats Or Mice
Continuous scurrying, squeaking or chewing from dusk to dawn is classic rodent activity. They move through roofs to escape heat or cold and search for food sources.
Electrical Safety Office data shows 1 in 4 house fires in NSW linked to pest damage start with rats chewing wiring [4].

Frequently Asked Questions
-
Can I remove a possum from my roof myself?
- No — possums are protected in NSW. Only an authorised pest controller can legally trap and relocate them, and you must install a replacement nesting box.
-
How long do birds stay nesting in a roof?
- Most local birds take 6–8 weeks from building to chicks leaving. Removing active nests without permission may also be illegal — we check rules first.
-
Are roof rats dangerous to health?
- Yes — they spread salmonella, leptospirosis and Hantavirus through droppings and urine. They also cause more electrical fires than any other pest in NSW.
-
Will noises stop on their own?
- Birds may leave once chicks fledge, but rodents and possums usually stay until access is blocked or they are removed.

Strange noises from a Sydney roof are often caused by animals entering roof cavities, including rats, possums and birds. The timing and type of noise can help identify the cause. Rats commonly create scratching and scurrying sounds overnight, while possums are often active around sunrise and sunset. A roof inspection can identify entry points and prevent ongoing damage.
