Blacktown’s older streets with bigger gardens and mature trees give possums plenty of options for getting onto a roof, and newer estates aren’t immune either, especially where street trees have had a chance to grow. The scratching and thumping usually kicks off around dusk when the possum wakes up and heads out to feed, then again near dawn when it returns. This page covers why possums end up in Blacktown roofs, how they’re safely encouraged to move on, and how to stop the next one getting comfortable.
Noise at night is the most obvious sign, thumping or scratching that starts not long after dark and again closer to dawn. A musty smell near one section of ceiling, small droppings around a manhole or under a particular part of the roof, and a single well used entry point, often around a tile, vent, or eave, are all worth checking for too.
A roof gives a possum shelter, distance from anything that might see it as a meal, and an easy route down to nearby trees at night. Blacktown’s mix of mature gardens and street trees puts a lot of rooflines within easy reach, which makes the jump from branch to roof a simple one. Once a possum settles into a spot, it tends to return to it, which is why the same roof can end up housing a new possum not long after the last one has moved on.
Possums are a protected native animal in New South Wales, so moving one on takes a bit more care than just chasing it out. The usual approach is to confirm where it’s coming and going from, then fit a one way door over that spot so it can leave to feed at night but can’t get back in the same way. Because possums tend to stick to routine, this often works within a few nights once it’s settled on a different place to shelter. The entry point only gets sealed once it’s confirmed the possum is out.
Possums are active after dark, so fitting a one way door only works if it’s done while the possum is out feeding. It’s also worth checking for young possums, since a mother may be carrying a joey during the cooler months, and rushing the process at the wrong time can separate them. That’s why timing usually shifts a little depending on the season.
Whatever entry point let one possum in will attract another unless it’s properly closed once the roof is clear. Sealing gaps around tiles, vents, and eaves, along with trimming branches that reach the roofline, removes the easiest path from tree to roof. Checking the roof after storms, when tiles can shift, helps catch a new gap before it becomes a way in.

They’re territorial and tend to return to a shelter spot they know. Unless the entry point is closed properly, a new possum, or sometimes the same one, often finds its way back within a few weeks.
No. Sealing an entry point while a possum is still inside traps it in the roof, which usually causes more damage and a worse smell than the original problem. Confirming it’s left before sealing anything matters.
They’re around all year, but activity tends to pick up in the cooler months when they look for warmer shelter, and again during breeding season when mothers are carrying young.
Yes, over time. Scratching, nesting material, and urine can affect insulation and ceiling linings, and the noise alone usually prompts most people to deal with it.
Once it exits through the one way door, it finds a new spot nearby to shelter, since possums don’t tend to travel far. The job is about getting it out and keeping it out, not moving it elsewhere.
Possums are a protected species, which limits what you can do on your own, and getting the timing or the door wrong can trap the possum inside instead of letting it leave. Getting someone to check the roof and confirm what’s going on is usually the more straightforward option.
