There’s no question that wind can be destructive. Without any clear plan or path, it can change course quickly and your roof could be at risk. What we do know is wind can be predictable in how it interacts with a built-up structure such as your home. Uplift pressure is created once wind hits the side of a building, forcing the air upwards. The wind will then move up across the roof beginning at the edges, causing the edges to become more damaged than other areas. Due to a roof’s large surface area, as the wind travels over it, it creates a suction pressure causing the shingles of your roof to lift up and tear off. Once the shingles are compromised, so is the entire integrity of your roof.
It is important to take note of your roof, especially after a storm, to check for any damages. There may be obvious signs of damage such as punctures or fallen trees, but there are smaller, less noticeable things to look for after a storm or even a windy day.
- Slightly raised shingles
- Debris deposits
- Damaged ridging
- Cracked flashing
You may even want to check inside your attic for any signs of water leaks or stains which could mean damage to your roof.
Different shingles are constructed to be able to withstand different types of weather conditions. Shingles are tested to ensure they can hold up against varying degrees of wind gusts. There are different classifications of testing which is dependent on the roof type. One of the testing methods is meant for steep sloping roofs and the other for sealed asphalt shingles. The classes test the uplift that will occur at different wind speeds. Most asphalt shingles carry the same wind resistance specifications, however, they may have different warranties depending on the manufacturer. If you want to know more specifics about your shingles, look into the manufacturer’s installation guide to determine your coverage.
If the wind is a concern, there are a couple of details you’ll want to consider when choosing shingles for your home. In addition to understanding the wind resistance of your shingles, you’ll want to consider factors that may play a role in any damages caused by wind. How your roof was installed and any unaddressed damages could influence the effect of strong winds. Be sure to fix any current damages to protect your home. Where your home is located as well as whether or not your roof is flat or has pitches are other factors that should be considered as well. Lastly, the age and current condition of your roof will play a role in how damaging wind can be to your shingles. Be sure to take all of these things into consideration when choosing shingles for your roof.
