If you have a roof in a windy area, then you should know that wind can cause a great deal of roofing damage. There are a few types of damage that are most common, and there are some things that your roofing contractor can do to keep them from occurring. Keep reading to learn about the damage and how it is prevented.
When the wind blows, it rarely hits the roof from the top down. Wind will typically blow in many different directions and can swirl around the roof. The swirling motions can cause the wind to flow underneath the shingles where it catches them and lifts them upwards. This is called wind uplift. The action of the wind can also cause bending of the shingles along the tabs where the exposed shingles meet the roof. A crease is then formed, and this greatly reduces the structural integrity of the shingle. Future bending and uplift issues are then more likely.
To stop uplift, your roofing contractor will look at the wind speeds in your area to see if there is a potential for shingle damage. If there is, then the professional will typically secure at least six nails to the shingles instead of the traditional four. Inspections should be scheduled to investigate shingles and replace them as needed if bends are noted.
Oftentimes, only damaged shingles need to be removed and replaced when inspections are completed.
Shingles are covered in small stones called roofing granules. The rocks protect the shingles from objects, like tree branches that may scrape and hit the roof. They also reflect light to minimize heat transfer. This can keep the roof cooler for longer, and it can also keep the shingles from drying out.
The wind can force the granules to blow off the roof though, and this can lead to unprotected shingles. In other words, your shingles are likely to wear much more quickly.
One way to avoid this issue to make sure that your roofing contractor is using shingles that are specifically designed to withstand strong winds. These shingles will be manufactured with more of the granules in the first place, which will be baked onto them. So, not only will the shingles resist high-speed winds, but there are more than enough granules so that some loss can occur.
