Keeping your roofing in good condition is one way to ensure it is ready to face harsh elements, including high winds. When strong enough, winds can cause granule loss, rip off loose shingles and even compromise the structure of your roof. After a storm, it’s a good idea to schedule a professional inspection. For your safety and to prevent further damage, avoid trying to perform repairs on your own.
Here are factors that can influence the wind resistance of asphalt shingle roofs.
Material
The materials that comprise a residential roofing system affect how well it withstands wind damage. It may help to know that asphalt shingles are not all made the same. The industry classifies them into four different categories according to wind resistance. For instance, Class D shingles can resist damage from winds up to 90 miles per hour (mph).
Moreover, the nailing depth of shingles largely depends on shingle thickness. A roof with thicker sheathing usually offers better resistance against high winds. You should also pay attention to the thickness of the decking because it plays a role in shingle wind resistance.
Installation
Even the best materials could deteriorate fast or sustain damage more quickly when not installed correctly. When not nailed properly, shingles become more prone to wind damage. A skilled contractor typically doesn’t recommend having a large overhang because it makes your roof more vulnerable to high winds. The pros will also recommend a roof pitch between 4:12 and 6:12 for added protection against winds.
Age
When was your roof installed? Roofing materials tend to deteriorate and weaken as they age. It means that older shingles are more likely to suffer from wind damage. To maximize the service life of your roof, be sure to schedule routine maintenance and inspections.
