What attracts possums to roofs?

Possums are drawn to roofs by warmth, shelter, and easy access. Overhanging trees, damaged tiles, open vents, and quiet roof cavities all make a home attractive to possums — particularly during cooler months or breeding season.

How do possums enter roof cavities?

Possums typically access roofs by climbing trees or fences and entering through gaps in tiles, open eave vents, broken soffit lining, or loose flashing. Even small openings of 5–6 cm are enough for a common brushtail possum to squeeze through.

Can possums damage insulation?

Yes, significantly. Possums nest in roof insulation, compressing and contaminating it with urine and droppings. This reduces its effectiveness and can create a hygiene issue that requires full insulation replacement.

What smells keep possums away?

Strong-smelling substances like quassia chips, camphor, peppermint oil, and eucalyptus can deter possums. These are best used in combination with physical proofing measures rather than as a standalone solution.

How do I know if possums are in my roof?

Common signs include thumping or scratching noises at night, a strong ammonia-like odour, dark oval droppings around the roofline, and visible entry marks or damage near eaves and tiles.

Can roof proofing stop possums permanently?

Yes — when done correctly, professional roof proofing using heavy-grade mesh and proper sealing techniques provides long-term protection. Regular maintenance checks ensure the proofing remains effective over time.
