SARKING IS NOT AN OPTIONAL EXTRA
You only get one chance to install roof sarking, so you might as well do it once and do it right.
It can only be done during the process of building the structure of the roof, but before the tiles go on.
It acts as a second skin, protecting the home against mould growth, and importantly, against the entry of storm-driven rain into the roof cavity.
Although considered an “optional extra” by some builders, Boral’s Harry Tanner says this is not something you can afford to skimp on.
“It’s not mandatory for builders to do this, and it might save you some money in the short term, but it does put homeowners at risk,” says Harry.
“The idea is that sarking acts a bit like a raincoat. When rain is wind driven the water can slide under the tiles, and that can happen to all roofs regardless of what material they are made of. Sarking stops the water from damaging the ceiling, discharging the water into the gutter and therefore protecting the home,” he says.
“The other thing is, when the weather gets cold, condensation forms on the underside of the tiles and water can trickle from that.
“That is another benefit of sarking.”
