Not every gap that lets a possum in starts out as a problem. Gable vents, ridge vents and small gaps around plumbing or roof penetrations are built into most homes on purpose, for airflow, but over time the mesh or grille behind them can rust, crack or come loose, turning a normal vent into an easy way in.
In Hamilton, older timber homes are more likely to have the original vent covers still in place, and these have often had decades to weaken. The crew we book checks every vent on the roofline during an inspection, not just the one thought to be in use, since a possum or a bird can just as easily use a second vent later even after the main entry has been closed.
The fix involves fitting new galvanised mesh behind or over each vent, sized so air can still move through freely but nothing larger than a small insect can get past it. This is usually done at the same time as sealing the main entry point, so the whole roofline in Hamilton is covered in one visit rather than needing a second trip later for a vent that was missed the first time. Weep holes along brick walls are left clear, since those need to stay open for the wall to breathe properly.
- Every vent on the roofline checked, not just the obvious one
- New galvanised mesh fitted behind or over each vent
- Airflow kept clear while closing the gap to animals
- Usually done alongside main entry sealing in one visit
