Australia isn't known for being a country you visit to enjoy the snow, so when a cold snap bringing ice and snow strikes many homeowners are unprepared. Ice dams on the roof is a problem many don't know how to address, but these can lead to roof repairs being needed after the ice has gone. As a homeowner, these are the four main things you need to know about this gift from nature.
How Did the Ice Dam Happen?
When the first snow fell on the roof of your home, some of it melted due to the heat radiating up from the inside. This water moved down to the edge of the roof, refroze and became a dam. This ice dam is now blocking any melting ice from moving off the roof.
Can Ice Dams Be Prevented?
Ice dams can be prevented by keeping your roof cool. As mentioned, the ice dam is initially formed by rising heat from the home melting snow on the roof. Having ventilation in the roof will allow cold air to enter the cavity space beneath the roof and cool the hot air trapped there.
When the air beneath the roof is cool, the snow and ice will evaporate more naturally. This gives it a chance to fully move off the roof onto the ground below. A roofing specialist can advise you on the best method of roof ventilation based on the size and shape of your roof.
Additionally, if you plan to remodel your roof in the future, give extra thought to how new insulation can keep the roof cavity protected from the heat of the home below. Make sure new insulation still allows for air to flow through this area to prevent the buildup of condensation as you don't want to be dealing with a mould problem in the years ahead.
