Your roof is the one part of your house that is at the forefront of protecting you from the elements. It can take quite a battering in certain weather, so an understandable concern people have when choosing a roof is how well it will hold up to their local climate.
Some people assume that metal roofs are unsuited to certain types of weather, but this is far from the truth. In fact, the modern metal roof might just be the perfect choice for withstanding anything nature throws at it.
One of the biggest concerns people have about metal roofs is how well they cope with rain. The two main worries are noise and rust.
Dealing with noise first, you might instinctively feel that heavy rain would make a real racket when falling on a metal roof.
This is an understandable worry and may have been the case with some roofs in the past, but it’s not a problem with modern metal roofing. As long as it’s insulated properly, you won’t notice any extra noise from a metal roof. Metal also reflects a lot of the sound away from the building rather so it won’t actually sound loud inside.
Remember, too, that the roof of a house is made from thicker and sturdier metal than the lightweight materials often used in outdoor structures like sheds and shelters.
In terms of rust, metal roofs are protected against corrosion by a tough coating. Choose a Colorbond steel roof, for example, and your roof is guaranteed to last, even in more challenging areas like the coast.
Metal conducts electricity, so people sometimes worry that a metal roof will be a serious hazard in a storm. In fact, metal roofs are extremely safe.
When lightning strikes, it uses the quickest route to the ground, which is often the tallest building or tree in the area. The material of your roof doesn’t make any difference to whether or not it’s struck, and metal isn’t any more likely to attract lightning than are other materials.
In the unlikely event your home is struck by lightning, having a metal roof is actually the safest option. This is because it won’t catch fire or explode, so it won’t cause a dangerous blaze that will spread throughout the building.
Since metal is good at absorbing heat, you may be concerned that it will make your house too hot when the sun shines on it. In fact, it’s a misconception that metal heats up more than other roofing materials, and metal is actually great at reflecting heat. You can increase this effect by choosing a lighter colour, though this is rarely necessary.
Additionally, metal quickly changes along with the surrounding temperature, so it cools fast when the sun goes down. With all this heating and cooling, metal will expand and contract like most materials, but it’s highly resistant to developing cracks as this happens.
The main worry with hail is the noise it makes, but insulated metal roofs protect against the sound of hailstones just as well as they do rainfall.
Something people don’t think about as often as noise is how damaging hail can be to some materials. Concrete and slate can be cracked and chipped by heavy hail, but a metal roof is able to withstand it well, coming away unscathed every time.
Heavy metal roofing stays firmly in place once it’s installed, with a much lower risk from extremely high winds than lighter materials. Metal also doesn’t have any separate slates that can blow away, so your roof will stay intact in high wind.
Another danger with windy weather is flying debris, but metal roofs are tough enough to resist most of the damage this is likely to cause, so there’s one less thing to worry about in high winds.
