Metal roofing has always been popular in Australia, but that hasn’t stopped a number of misconceptions circulating. We’ll do our best to dispel the 5 most common ones.
Metal Roofs are Noisy
Your often hear people say how they love the sound of the rain on a tin roof. And we’ve all been in a shed during a rainstorm and had to shout to make ourselves heard over the din. So, it’s no surprise that the idea that metal roofs are noisy has taken hold. We’re not going to tell you that you won’t know it’s raining during a thunderstorm, but the noise isn’t a problem that will interfere with the way you live. What with insulated ceilings and the roof space between you and the roof itself, the noise is minimal. You won’t even have to increase the volume on the TV, and it would have to be a serious hailstorm to wake you up at night.
Metal Roofs Rust
Like saying that the noise of rain on metal roofs is loud, it’s obvious that metal roofs rust – we’ve all seen them. But how many of those rusty roofs have rusted all the way through and how old are they? The days of corrugated iron protected by a regular coat of paint are long gone. Those rusty roofs you may have seen with peeling paint would be well over 50 years old. They could even have been keeping out the rain for a century. The steel used these days is much more enduring than them and you are very unlikely to observe it slowly corroding away in your lifetime. So, yes, metal roofs eventually rust, but that is very much a problem for future generations.
Metal Roofs get too Hot and too Cold
We all know how hot a steel fence panel can get in the sun and how cold to the touch they can be on a winter’s day. After all, tin sheds can get insufferably hot and really cold. But the fact is that metal roofs are comparatively reflective and don’t absorb as much heat as concrete and terracotta tiled roofs do. The real advantage they have, however, is that they shed heat very quickly. A metal roof will cool down faster than tiles and will warm up faster too. In conjunction with good insulation, you won’t have any problems with temperature extremes if you choose a steel roof.
Metal Roofs are no Good in Storms
Vision of cyclones always seem to include a flying sheet of roofing iron. Loose or poorly installed roofing sheets are not things you want to be around during a serious storm, but you might be surprised to learn that metal roofs are considered a good option, as long as they are properly secured. A related myth is that metal roofs sustain more hail damage, but this is not the case. Dents can occur in extreme conditions, but the same conditions crack and even smash tiles.
You can’t Walk on Metal Roofs
There are no problems walking on metal roofs provided they are adequately supported. They won’t dent of sustain any damage, although we strongly advise against walking on a pitched roof without an appropriate safety harness. Roofs can be slippery.
The truth about modern metal roofing is that it is an excellent and enduring roofing material without any serious downsides. No wonder it remains so popular.
