Possums commonly enter homes through broken roof tiles, damaged ridge cappings, loose flashings and gaps in eaves. Once inside they can create noise, damage insulation and leave droppings throughout roof cavities. Many Berwick properties are surrounded by established trees, giving possums easy access to rooftops and increasing the risk of ongoing infestations if entry points are not properly sealed. Early detection and professional proofing can help prevent recurring possum problems and reduce the risk of costly roof repairs.
