Building a Roof to Withstand Cyclone Force Winds

In areas prone to cyclones and hurricanes, it is essential for your roof to be built and maintained in such a way that it can withstand those powerful winds. A well-constructed roof is the best defence against these strong winds, so what is the best approach when building or maintaining your roof in cyclone-prone areas?

Materials Used in Construction

The right materials are key when constructing a roof that will stand up against cyclone-force winds. The roof should be made of high-grade steel, aluminium, or concrete tiles designed specifically for these vulnerable areas. In addition, steel or aluminium roofs should be strong enough to resist the type of wind you could expect in a landfalling system. Some states will specify these minimum criteria. By the way, corrugated iron roofs are not recommended as they are easily damaged by high winds.

Roof Design Considerations

The shape of the roof also plays an important role in withstanding cyclone-force winds. For instance, low-sloping roofs and hip roofs have more surface area exposed to the wind than a gable or gambrel roof, making them less likely to be damaged by strong winds. Additionally, adding bracing along the length of the rafters will help strengthen the structure of your roof and increase its ability to withstand extreme weather conditions. Furthermore, homes located in coastal regions should include extra bracing and anchoring systems around windows and doors, as these are often weak points during extreme weather events.

Maintenance Tips

Maintaining your roof regularly is one of the best ways to ensure that it can withstand powerful winds associated with cyclones or hurricanes. Inspect your gutters for any obvious signs of damage or leaks, and make sure that they are properly secured at all times. It's also important to regularly check for loose nails or other metal fittings, which could become projectiles during storms and cause damage to nearby structures or people.

Your Best Approach

If you live in an area prone to extreme weather events, it's always best practice to have a professional inspect your home every few years. These roofers will look for any potential issues with your roof structure that could put you at risk during future storms. And if you're building something from scratch, ensure it is up to code and always work with roofers who have experience in this area. They'll keep up with the latest technology and will incorporate these techniques into their building work to stand the best chance of success.
