42% of all Victorian homes inspected have roof problems. 

According to Archicentre, research from its pre-purchase home inspections program has shown 42% of all homes inspected have roof problems.

David Hallett, Victorian State Manager of Archicentre said, "home owners need to be extremely careful about climbing on slippery roofs and urged residents to leave this to professional tradespersons with the appropriate skills and equipment."

The Medical Journal of Australia has reported that, on average, in Victoria, more than 1,000 people per year attend hospital from ladder falls. The majority of those injured were men aged 50 and over who fell more than one metre. 20 people a year die in Australia from ladder falls.

Mr Hallett said following major storms and heavy rain, leaky roof problems can lead to dangerous situations where water can penetrate walls, roof linings, and insulation leading to the growth of mould and deterioration of the home.

"People who put off having leaks fixed could be putting themselves and their families at risk, especially if the water was likely to enter the electrical system or appliances".

"The roof as the vital part of the home, often escapes the scrutiny of the home owner as it is out of sight. Water pouring down the walls or a section of plaster collapsing is often the first indication that there is a problem," Mr. Hallett said.

"The cost of damage by leaking roofs on plaster, especially lath and plaster in older homes, can run into thousands of dollars. This damage can be caused by a simple lack of maintenance in clearing out guttering or downpipes".
