If you’re having your roof structure rebuilt or are building a new house from the ground up, you have the opportunity to choose a roof style that offers better resistance against high winds.
Storm restoration specialist Viking Contractors, LLC shares a look at the roof styles that can best withstand high winds.
Qualities and Features of a Wind-Resistant Roof
Pitch is an important factor when designing a roof for wind resistance. Shallow-pitched roofs perform better against wind, especially for single-story homes. The reduction in pitch can make the roof less visible. A capable roofing contractor, however, can help you design a roof that balances wind resistance and curb appeal.
The number of slopes likewise play a part. The more slopes your roof has, the better it performs against high wind. Wind tends to uplift, and more vertical surfaces with sudden stops at the peak create a vacuum that tends to pull the roof up. In some cases it creates damage to other parts of the wall, requiring
storm damage window repair. Reinforcements such as hurricane straps can also strengthen the roof against uplifts.
Wind-Resistant Roof Styles
Accounting for all these factors can give you a good start in designing your wind-resistant roof. For instance, a typical home with a rectangular floor plan has an equally typical gable roof. By simply changing the roof into a hip roof—essentially doubling the number of slopes—the home’s wind resistance is improved several times. Since wind tends to uplift, reducing the overhang to 20 inches at most can further improve wind resistance.
Flat roofs are another option that works especially well in contemporary home designs. Traditional built-up roofing is much heavier and therefore resists uplift, but the gravel layer could turn into flying debris if the wind hits the roof at the wrong angle. Instead, consider membrane roofing like TPO or EPDM. Choose a fully adhered installation method; while it does take longer to install and could cost a bit extra, it basically laminates your roof. Compared to ballasted installation methods, a fully adhered flat roof will just let wind sail over its surface.
