Castle Hill’s leafy streets, big gardens, and mature trees make it comfortable territory for possums, and a lot of residents end up sharing a roof with one at some point. The thumping and scratching usually starts around dusk when the possum wakes and heads out to feed, then again closer to dawn. This page covers why possums end up in Castle Hill roofs, how they’re safely encouraged to leave, and how to keep the next one out.
Noise at night is the giveaway, thumping or scratching not long after dark and again near dawn. A musty smell near one part of the ceiling, droppings around a manhole or under a section of roof, or an obvious entry point around a tile, vent, or eave showing signs of use are all worth checking.
A roof cavity offers shelter, safety from anything that might see the possum as a meal, and an easy path down to nearby trees at night. Castle Hill’s bigger blocks and mature gardens put plenty of rooflines within easy reach of a tree, which makes the jump an easy one. Once a possum settles somewhere comfortable, it tends to keep returning, which is why the same roof can end up with a new possum before long.
Possums are a protected native animal in New South Wales, so it isn’t as simple as chasing one out. The general approach involves confirming where it’s coming and going from, then fitting a one way door over that spot so it can leave to feed but can’t get back in the same way. This usually works within a few nights, and the entry point only gets sealed once it’s confirmed the possum is out.
Possums are active after dark, so a one way door only works when it’s fitted while the possum is out feeding. Checking for young possums matters too, since a mother may be carrying a joey during the cooler months, and rushing the process at the wrong time can separate them.
The entry point that let one possum in will keep attracting others unless it’s closed properly once the roof is clear. Sealing gaps around tiles, vents, and eaves, plus trimming branches that reach the roofline, removes the easiest path from tree to roof. Checking after storms helps catch a new gap early.

They’re territorial and tend to return to a shelter spot they know, so unless the entry point is properly sealed, a new possum often finds its way back in.
No, sealing while a possum is still inside traps it in the roof, which usually causes more damage and a worse smell. Confirming it’s left before sealing is important.
They’re around all year, but activity picks up in the cooler months and again during breeding season when mothers are carrying young.
Yes, scratching, nesting material, and urine can affect insulation and ceiling linings over time.
It finds a new spot to shelter nearby, since possums don’t travel far. The focus is on getting it out and keeping it out.
Possums are a protected species, and getting the timing or door wrong can trap the possum inside instead of letting it leave, so getting someone to check the roof is usually the simpler option.
