Debunking Common Myths About Metal Roofing in Perth
If you are trying to decide the best roofing material for your Perth home, you may be considering a metal roof. As you do your research, it can be confusing because there is misinformation out there, along with the correct facts. Metal roofing in Perth can keep your home cooler than other standard materials like asphalt.
Here is some good information to consider.
Myth: Metal roofs make your home or business hotter.
Of course, there are different types of metals that can be used for roofing. Each type of metal has different properties, especially when it comes to conducting heat. Copper will conduct heat exceptionally well (which is why you see cookware with copper bottoms), but stainless steel is a poor conductor. So when you look at roofing materials, the composition is important.
Myth: All metal roofs are equally heat-conductive.
So, if you have a roof that conducts heat very well, it is going to make your house or office building hotter. There are some metals that absorb heat but are not very good conductors. Asphalt conducts heat poorly but standing on an asphalt street in the middle of summer, you will feel the heat rise. Because asphalt releases heat gradually, it is one of the leading causes of the urban heat island. A properly installed metal roof system allows heat to escape rapidly, helping keep your home cooler overnight..
However, conductivity is not the only factor to consider. You also need to think about how the metal will reflect the sun’s energy. Metal roofs can be made in a lot of different colours. The darker the colour, the more heat it will absorb. Choosing light-coloured panels improves energy-efficient roofing performance by reflecting solar heat away from your home.
Myth: Metal roofs are entirely made with metal.
The shingles of your roof may be made of metal, but there are more elements to a roof than that. Joists are wooden, and insulation is its own product. All the construction materials work together to bring you the best summer cooling possible. You may want to consider above sheathing ventilation. This permits air to flow between the sheathing and the insulation, and then the air is released outdoors.
You can order an energy audit that will include an infrared roof inspection. That will locate weak points in the insulation that can pose heating or cooling problems.
So, with the right kind of metal roof, you can actually keep your Perth home cooler in the summer than with a traditional asphalt roof.
