Wahroonga’s big trees and bushland border make it one of the more possum prone suburbs on Sydney’s Upper North Shore. With so many homes sitting close to Ku ring gai Chase or backing onto reserve land, a possum has an easy run from the canopy straight onto a roof, and once it settles in, the nightly thumping usually follows soon after. This page covers why Wahroonga roofs attract possums and how they get moved on properly.
Heavy footsteps or scratching not long after dark, often repeating again closer to dawn, is the clearest sign something has moved in. A musty smell over part of the ceiling and an obvious gap around a roof tile, chimney, or old eave are also worth checking for.
A roof offers shelter that sits right next to a possum’s usual feeding ground, and in Wahroonga that feeding ground is often the bushland or established trees just metres from the house. Larger, older roof voids in this area also give a possum more room to settle in undisturbed than a tighter modern roof space would.
Possums are a protected native animal in New South Wales, so the process is built around encouraging the possum to leave rather than forcing it out. Once the entry point is confirmed, a one way door is fitted so the possum can head out to feed but cannot get back in through the same gap. In Wahroonga’s larger roof spaces, confirming the exact entry point can take a bit more time than in a smaller, more straightforward roof.
A one way door only works once fitted while the possum is out feeding after dark, so timing the job matters. Checking for a joey is also part of the process, especially in the cooler months, since separating a mother from her young by rushing the job is worth avoiding.
Once the roof is clear, properly sealing the entry point stops the next possum from finding the same way in. Given how much bushland surrounds Wahroonga, it is also worth checking nearby gaps such as loose flashing or old vents, since a possum will use whichever opening is easiest.

They are territorial, and a home backing onto bushland will often see the same possum return unless the entry point is properly sealed.
No, sealing while a possum is still inside traps it, which usually leads to more damage and a worse smell than before.
They are active year round, with more movement through the cooler months and again during breeding season.
Yes, bigger blocks with more established trees, which describes much of Wahroonga, tend to see possums more often than smaller, more open blocks.
It moves to a nearby tree or another roof close by, since possums generally stay within a fairly small home range.
Possums are a protected species, and Wahroonga’s larger roof voids can make it harder to confirm an entry point without a proper check, so getting the roof looked at is usually the more straightforward option.
