Climate change tougher than Sydney roofs


The Insurance Council of Australia (ICA) called on the Federal and State governments to toughen the Building Code of Australia and address the problem of "brittle buildings".

It seems research conducted by Professor Alan Jeary, a structural design specialist from the University of Western Sydney's school of engineering, concludes that roofs tiles will not withstand the onslaught of a summer storm season. Sydney's present roofing materials - up to 75 per cent ceramic tile and 10 per cent slate - were easily damaged by relatively minor hail storms.

In the past 20 years, Sydney has been hit by five significant hailstorms, which have caused more than $6 billion damage. Climate change research indicates that the problems could get much worse.
