As the damage bill from last week's hail storm balloons to more than $1 billion, Brisbane's disaster-weary residents are scrambling to prepare for more wet weather.

Showers are forecast for the city today with a chance of afternoon storms this weekend.

While the weather will not be as violent as the supercell, it is still bad news for 1,900 households whose hail-damaged homes have been left vulnerable to more water damage.

Hail caused roof damage to nearly 2,000 homes and 60 are yet to be covered with tarpaulins.

In the initial days after the storm authorities thought the damage bill could reach $150 million, but insurers and the Brisbane City Council said costs had spiralled.

The Insurance Council of Australia on Thursday estimated the insurance loss stood at $482 million, with 17,509 home claims and 51,472 car claims lodged.

Brisbane Mayor Graham Quirk put the total damage bill higher and said it was the biggest storm event for insurance companies in more than 30 years.

"I'm told the bill is going to be around $1 billion, claims for one insurer alone are around $300 million."

Council has now cleared more than 4,000 tonnes of green waste and flood-affected furniture but the Mayor said that was a small percentage of what is out there.

Every resource was thrown at the clean-up, including enlisting private sector trucks to clear the waste.

"We have been here before, we know what needs to be done," Mr Quirk said.

Council will wave fees at local dumps until Sunday to encourage residents to clear their own homes.

Brisbane still coming to terms with the damage

Some Brisbane residents were left homeless when insurance contractors moved in.

Standing at a crumbling brick apartment block in Herston, carpenter Daniel Van Heerden explained the entire structure was unstable.

"We're taking a roof off that flew off another roof about 400 metres away," he said.

"It's just to make it safe so they (insurers) can access it and see what needs to be done."

Neighbour Louise McBryde's home was also damaged when chunks of the same roof crashed into her ceiling.

The whole block was affected by asbestos.

Chunks of the fibre can be seen wedged amongst tree branches and scattered around the yard.

"They asked us to leave, but you just want to be at home at times like this," Ms McBryde said.

"We've got chickens and cats and dogs who have already been traumatised so we just decided that, no, we've already been exposed to the asbestos, we're just going to stay and get on with things.

"The ceiling is starting to sag and we don't know if the tarps are going to hold.

"If we get another storm like the last then that will be the end."
