Wind damage is a typical type of weather damage that can occur on roofs, and other types of damage such as hail damage are not uncommon either, and roofs can even get indirect storm damage by having trees and other debris fall on them or by getting their gutters clogged up with leaves and developing a leak from the backup. However, you may not have heard of every type of weather-related damage that your roof could incur. Here are a few more types that you should familiarize yourself with.
1. UV rays
UV rays can oxidate both asphalt driveways and asphalt shingles. That is to say, they create a chemical reaction that removes oxygen from the material, making it more brittle and consequently more susceptible to damage from other types of bad weather because it can't absorb blows or stretch to accommodate temperature changes as easily as it could before. You can minimize damage from UV rays by choosing a material that reflects sunlight rather than absorbing it, or by coating your roof with a "cool roof coating" that will do the job for you. Of course, you should check your roof's warranty before you decide on this coating. Cool roof coatings have been developed for asphalt shingling, but some companies have warranties that are voided by coatings anyway.
2. Thermal shock
Thermal shock is a name for the damage that happens when, as mentioned above, your roof isn't stretchy enough to absorb temperature changes. Temperature extremes can by themselves be taxing to your roof, but extremes in temperature change are even worse because the roof material then has to change size suddenly (since the material shrinks slightly when colder and grows slightly when warmer). This problem is compounded with asphalt shingle roofing material because it captures and stores heat so well that it can get much hotter than the surrounding air during the day. A cool roof coating or a naturally reflective roofing material (or both) can once again greatly reduce your roof's chances of becoming damaged by this weather feature.
3. Granule loss from hail or wear
You may not notice this problem at first if you don't happen to be cleaning out the gutters shortly after it starts. Whether it's from normal wear and tear or from violent damage such as hail knocking the granules loose, it can start out quite subtle. And even if you do see roofing granules in your gutters, you may not realize that it's a problem. After all, the granules are pretty loose and some of them come off every time the shingles are handled, right? But if they're coming off in significant quantities, the roof could end up having trouble protecting your home from the weather. These granules are supposed to block UV rays and other harmful weather from making direct contact with the underlying material, so the fewer you have left, the more vulnerable your roof is.
All of these types of weather damage can strike your roof without warning, and both are more likely to harm your roof if it's a sun-sucking asphalt shingling one. Be sure to get regular inspections to check for these types of weather damage, and consider getting a different type of roof next time. If you do decide to continue using asphalt when you next replace your roof, at least try to use light-colored shingles or find a contractor who won't void the warranty if you slap on a cool roof coating later.
