Roof damage can occur even when the wind is blowing at just 30 mph. However, the type of damage and severity will vary depending on wind speed. For example, if you have old or damaged roof tiles, they are more likely to fall off the roof in strong winds. In the Houston, Texas area, winds that reach the mark of 58 to 74 miles per hour can cause significant damage to most roofs, even the newest ones. This wind speed can uproot trees, tear off healthy roof tiles and even damage chimneys.
Winds of more than 50 to 60 miles per hour can tear off a roof, according to the National Severe Storm Laboratory (NSSL). However, if you live in an area prone to hurricanes, a roof should be designed to withstand winds of up to 150 mph. In that case, winds that exceed that threshold can cause significant damage to the roof. When an average speed of 40 to 80 km/h (and gusts of 70 to 130 km/h) is reached, an amber warning is issued.
In this phase, structural damage to roofs, including roof tiles, is to be expected. It's important to check the ceiling and the fascia (the boards that lie under the roof edge and the beams), as damage that occurs there can also cause leaks and allow pests to enter stealthily. For example, already weakened roof tiles can be damaged or lifted, and tree branches can break, which could damage the roof in the event of an impact. You can also check your attic for leaks or mold, as this may indicate a problem with roof maintenance. If wind damages your roof, it's important to work with an accredited roofing contractor to perform the necessary repairs.
Objects, such as patio furniture or garden tools, can become dangerous projectiles when there are strong winds, posing a serious threat to the integrity of the roof. Remember that you can opt for a free inspection of your roof to determine if it needs to be repaired or replaced. Poorly or average-built homes will have partial wall and roof faults, as well as burst windows. The wind can lift the material and tear it apart or leave it with bubbles, damaging the integrity of the cover.
That's why it's so important to watch for signs of wind damage and to have your roof inspected by a professional if you suspect it may be damaged. Nearby gardens can also pose a threat, as trees begin to uproot or large branches break off and crash into the roofs. These loose parts of the roof are easy targets because winds can more easily break loose roof tiles and cause a chain reaction. When you check your roof for wind damage, you should also consider how old it is and how well you've maintained it over the years.
Taking these steps can dramatically reduce the risk of serious roof damage during a hurricane, as it protects not only the roof itself, but also the entire structure of the house. The selection of materials specifically designed to offer high wind resistance can provide fundamental strength to your roof. Reinforcing the roof covering by ensuring that it is properly attached to the beams or frames increases overall stability and wind resistance.
