Storm cover is built around sudden damage, not routine maintenance. When a tree comes down in high winds, the insurer needs to know whether the storm caused the failure or whether decay, root problems or neglect were already there. A written report from a qualified arborist answers that question. Trees Down Under can inspect and report on storm-damaged trees across Sydney, any time you call on 0475 463 597.
The report records the cause of failure, the extent of the damage, the condition of the tree, any ongoing safety risk and the recommended action, including tree removal where it is needed. Because it comes from an independent professional, assessors tend to give it real weight when deciding whether damage was sudden or pre-existing.
One thing to be clear about: the report supports your claim, but the insurer makes the final decision. A thorough, well-documented report gives the assessor the evidence they need to make it.
