Over half of all NSW claims in the 2019/20 financial year were related to storm damage.

The top five areas for storm damage claims were, in order: Dubbo, Orange, Parkes, Forbes and Mudgee.

Bathurst was placed twelfth, behind Kelso, Lithgow and Cowra.

Orange SES deputy unit commander Paul Beard said the crew received hundreds of calls a year for help related to storm damage.

One job, a few months ago, saw the crew attend a property in Prince Street where a tree had fallen onto a garage housing a 1970s Rolls Royce.

"It completely took out the garage - flattened," said Mr Beard.

He said that although fallen trees were responsible for some home damage in the area, most storm damage-related issues were about guttering, and what happened when it was overwhelmed.

"Primarily, it's about roof damage.

"When water gets into the house most of the time it's because gutters are full, and when they're full the water can't go down the pipes and overflows into the eaves and gets into your ceiling."

Mr Beard said people were often unaware of the problem until it was too late and water had begun pooling behind walls near power sockets.

"We've had a number of jobs where people didn't know they had a leaking roof until water started coming out of their power points."

By this stage the potential issues had moved beyond gutters, mould and water damage to structures to include carpets and electronic devices such as computers and TVs.

NRMA's community research in October found 62 percent of NSW residents are worried severe weather such as storms are becoming more frequent and intense.

It also found 43 percent are worried that climate change is making storms more frequent and intense.

More than eight in 10 said they experience "storm stress", with the top two areas of concern being potential damage to homes (53 percent) and the ability to drive safely in difficult conditions (40 percent).

However only 35 per cent had taken steps to prepare for storm season.
