What’s The Best Roofing for High Winds, Cyclones & Storms?
Homeowners in Townsville and North Queensland are well aware of the risks posed by tropical storms and cyclones. Griffith University estimates that approximately 10 tropical cyclones hit the region each year.
Most of these are Tropical Cyclones that contain wind speeds of up between 62-88 km/hr. These can cause damage to trees and localised power outages but pose little risk to property and people.
But a handful of storms each year reach the Severe Tropical Cyclone category. These contain wind speeds of 118+ km/hr and are strong enough to cause major structural damage to roofs and outbuildings.
The good news is that you can greatly reduce the risk of damage by ensuring your roof is capable of withstanding higher wind speeds. In this article, we'll look at the wind resistance properties of all the major roof construction types.
Table of contents:
Composite Tiles
Composite tiles are one of the most common types of roofing material in this part of Australia. They come in many styles and colours making them suitable for almost any style of home.
The wind resistance of composite tiles varies depending on the design. Curved tiles offer the best performance because they interlink to create a strong structure. A roof made from curved composite tiles can withstand wind speeds up to 200 km/hr.
However, every few years a storm hits the area with wind speeds over 200 km/hr. Recent examples include Cyclone Niran 2021 (260 km/hr), Cyclone Debbie 2017 (215 km/hr), and Cyclone Yasi 2011 (250 km/hr). So, keep this in mind if your home is in an exposed position.
Ceramic Tiles
Ceramic roof tiles have excellent fireproofing properties. This makes them popular in regions that are also at risk from bushfires, but the wind resistance of ceramic tiles is similar to composite tiles.
That means the performance of the roof will depend on the style of tile used. Much like composite tiles, curved designs offer the best wind resistance. Spanish style tiles, which are heavily curved, also provide good wind resistance.
But even a carefully designed ceramic roof is unlikely to be able to withstand wind speeds above 200 km/hr. So, this type of roof tile is only suitable for properties located in sheltered areas.
Slate Tiles
Natural slate tiles are popular due to their superior appearance. However, slate roofs cost quite a bit more than other roofing materials, and the wind resistance performance is average at best.
The problem with slate tiles is that they are heavy and the tiles themselves are flat. This allows them to be easily lifted by strong winds. Once lifted they are easily dislodged leaving the roof structure compromised.
The quality of construction is thus important when using slate tiles. You need to ensure the tiles are properly tied down using roof nails every 2 cm. But even if properly installed a slate roof is only going to be able to withstand wind speeds of up to 177 km/hr.
Shingles
Asphalt and wood shingles are less expensive than other roofing materials. And their rustic appearance complements older character style properties. This makes shingles an increasingly popular roofing material.
However, the wind resistance of shingles is much less than other roofing materials. A roof constructed from new wood shingles is only going to be able to withstand wind speeds of up to 177 km/hr.
While a roof made from recycled shingles may only be able to withstand wind speeds up to 80 km/hr. This will result in roof damage during even a modest tropical storm. So it is advisable to make sure a shingle roof is suitable for the location before installation.
