Many first-time buyers of metal roofs are worried that their choice will result in a lot of noise, and wonder whether the benefits offered by materials like steel (which is durable, economical and environmentally-friendly) outweigh “the sound factor”. You’ve probably been under one of the old tin roofs that still cover many barns, sheds and houses in South Africa, and found it to be a bit cacophonous in bad weather, or when cats, birds (or monkeys, depending on where you were) scampered around. Trees too, when overgrown, have been known to make a din with their bashing and scraping on a metal roof. However, good metal roofs today are very different – here’s why.
Busting the noise myth
When installed properly, a steel (or other type of metal) roof is as noisy as an asphalt shingle roof; which is to say, not very noisy at all. Correct installation focuses on three key areas: roof underlayment, fasteners and insulation.
Firstly, the roof needs to be installed with the right type of roof underlayment, which provides a physical barrier between you and the noise. If this is done well, ceiling insulation might not even be necessary – though it can, of course, provide thermoregulation benefits, as well as extra sound muffling, so most people opt to have it included.
It is essential to make sure the roof is fastened in place; if any fasteners are missing or come loose, the roof runs the risk of becoming noisy – particularly in inclement weather. To this end, regular checks are required. Having the roof fitted and maintained by professionals ensures that noise is a non-concern.
A word on roof profiles
Generally speaking, the more raised the roof profile is, the noisier it will be due to the level of vibration that occurs. So if you are really worried about noise, opt for flat profiles instead of corrugated – it will make a difference on rainy days.
Busting the lightning myth
While we’re debunking myths about metal roofs, we might as well tackle another common concern that customers have. Is lightning more likely to strike a metal roof? Will you go up in flames? The answer is no, to both of those questions.
Lightning is no more likely to strike a metal roof than any other type of roof; and metal roofs are actually more likely to safely discharge the energy if they do get hit. Furthermore, they aren’t flammable – giving them a distinct advantage over their wooden counterparts.
Busting the “bad for the environment” myth
We’ll bust one more myth while we’re at it: metal roofs are not the environmentally problematic material that so many people think they are. Materials like steel are fully recyclable, meaning that precious resources can be conserved. And because steel and other metal roofs are so long lasting (they often outlast the building beneath), they typically do not require replacement – reducing unnecessary consumption of materials.
