The Elements That Make Roofs Resistant to Wind Damage
A roof can be constructed to be more wind-resistant, especially in the event of hurricanes and strong wind events. Certain elements must be present within the system for it to handle the loads forced upon it. John Peters Roofing, your local residential roofing contractor, discusses these elements in detail below.
The Roof’s Design
When it comes to better wind resistance, hip roofs stand out over gable roofs and other roof styles. This four-sided roof tends to be more aerodynamic and has an inherent resistance to high winds’ uplift forces. However, when your home has a gable roof, it is important that the end walls are braced to prevent them from collapsing.
Roof installation contractors like us also recommend a pitch of 3:12 to 6:12 (that is, three to six inches of rise for every 12 inches of run) to ensure the roofing system’s wind resistance. This moderate pitch results in lower loads on the home than with flatter or steeper roof pitches.
The Roof’s Primary Components
While roofers recommend the use of specialized hurricane nails to keep the roof decking secure, the nailing and the use of material must be followed during installation to ensure high wind resistance. For instance, a 7/16 to 19/32-inch plywood must be attached with nails spaced three to six inches apart. Meanwhile, hurricane straps connect the wall framing to each rafter or truss to achieve needed uplift loads.
The Roofing Material
When you are looking to pursue roof replacement, it is always a good idea to choose roofing materials that are tested and certified to withstand wind damage. Look for those tested to UL 2218 with a Class 4 rating for impact resistance, as well as those with ASTM D 3161 high wind resistance ratings.
