Tapping sounds in your Australian roof are often caused by wildlife (possums, birds, rodents, geckos), loose roof tiles or metal sheets shifting in the wind, tree branches hitting the roof, or thermal expansion of materials; less commonly, it could be water dripping from a leak or even termites, so identifying the sound's timing and nature helps determine if it's pests, weather, or structural issues needing professional inspection, say experts.
A banging or popping sound can be the result of nails loosening or wood shrinking. A tapping sound could be caused by a loose shingle or tile. A ticking sound could be a sign of a leak.
Aside from the suggestions of rats or a possum, other options could be a leak in your roof (tapping noise from water or condensation dripping onto something) or maybe expansion / contraction as the house cools can make a tapping noise.
This sound usually indicates that there is a water leak either in the ceiling or in the wall. Typically this will show up as a water stain near the source of the leak. Sometimes this sound is related to the thermal expansion of drain lines from cold or hot water running through it.
Expansion and Contraction – The Most Common Cause
As temperatures drop after sunset, roofing materials such as wood and metal contract, leading to sharp, sudden noises. This is common in tile roofs, which retain heat and cool down gradually, causing movement in the structure.
Attics often house parts of a home's plumbing system which can sometimes produce strange noises. Water Pipes: Pipes expanding or contracting due to hot water usage can create ticking or tapping noises.
Noises. If you hear a scampering/scratching noise coming from your ceiling, it will usually indicate some type of animal in your roof. Possums are common, but they sound like a herd of elephants are living in your roof – mice and rats are more subtle but still can be heard, particularly at night when lying in bed.
So-called ventilation disorders in the ear also cause a tapping noise. In this case, the function of the so-called Eustachian tube, which is responsible for ventilation and thus pressure equalisation in the middle ear, is disturbed.
Rats can create noticeable scratching sounds with their sharp claws as they move and burrow within the concealed areas of your home, especially audible during the night. You might also hear swift, scuttling noises signaling their movement across surfaces, resembling light tapping or the rapid drumming of fingertips.
Yes—it absolutely can be. While some causes of engine knocking are relatively minor, persistent knocking can seriously damage pistons, bearings, and other internal engine components. Ignoring it now could mean a complete engine rebuild down the road.
What is the fastest way to get rid of roof rats?
Possums and rats make very different sounds from one another. Rats tend to make a scuttering sound, as their claws tip-tap across your roof cavity. Possums are larger animals and often make more noise. Running sounds and scratching sounds coming from your roof is a good indicator that you've got a possum infestation.

Skunk Noises
Skunks usually click their teeth, squeal, or hiss in a high-pitched manner. Skunks in your home also make tapping and scratching noises with their long claws. Skunks are usually nocturnal, and will likely be under your deck or in your crawlspace.
Termites are often silent pests, but when you do hear them, they can produce a soft clicking or rustling sound as they chew through wood or communicate within their colonies. This sound is subtle and can easily be drowned out by the everyday sounds of a busy household.
Roof rats make high-pitched chirps and squeaks to communicate with other rats or when they feel threatened. Scurrying and scratching noises as their feet move along surfaces such as floors and rafters or when they are building their nest. Even though these sounds are soft, they can be heard at night when all is still.
Mice and rats commonly seek refuge in the cozy spaces in walls of your home. This is the most common place you will hear their quick light tapping and scratching sounds. FYI - walls act as a hidden highway system for them to move unseen through out a home.
Look for signs of rat or mouse infestation: Rodent droppings around food packages, in drawers or cupboards, and under the sink. Nesting material such as shredded paper, fabric, or dried plant matter. Signs of chewing on food packaging.
Thumping or Tapping: Another sign of pest infestation with rodents, birds, or bugs moving and nesting throughout your roofing system. Popping: This sound can be normal from your materials expanding and contracting during temperature fluctuations.
There is usually a simple explanation for why your walls are making a knocking sound. Most often, it's your home's plumbing system. It may be due to fluctuating water pressure issues, loose plumbing pipes, or a faulty valve.
Problem 2: Alternatively, the ticking sound may be caused by expansion and contraction of pipes carrying hot or cold water, as their temperature changes. Solution: Install insulation around the pipe. Problem 3: You may also be hearing a ticking sound due to a loose or unstable pipe.
Below are the most common culprits and the signs to look out for:
Roof rats are nocturnal, meaning they are most active at night. As soon as the sun goes down, roof rats start foraging for food and sometimes travel several hundred feet seeking food to eat and store.
Animal Vocalizations
Shrill squeaks are often indicative of rats or mice, and sharper 'shrieks' may indicate infestation. Raccoons are known to produce squealing, chattering, and growling sounds, especially when they have kits (babies). Lastly, bats will chirp at night or in the morning before sunrise.
