In order to protect your roof from the elements, the material used on the surface of the roof is known as Granules. They are designed to protect them from the sun, rain, hail, and other weather elements. Putting it briefly, roofing granules provide an extra layer of protection for your roof by absorbing some of the weight that might otherwise be applied to it. Ultimately, this will help to prolong the life span of your roof and enhance its aesthetic appeal at the same time! The granules on asphalt shingles are designed to keep the asphalt shingles from sticking together as well as to offer installers a smoother walking surface on which to work. Granules are an essential component of asphalt shingles that are meant to withstand the elements that they are subjected to every year, not only from the hot sun, but also from rain, hail, and wind. Granules help to ensure that roofing shingles continue to function properly for many years, as they are exposed to harsh weather conditions over the course of their lifespan. Granules added to asphalt shingles help them blend in aesthetically with their surroundings, which adds a bit of subtlety and charm to the roof. As a result of roof granules, your roof is better protected from the sun’s harmful ultraviolet rays, which can cause shingles to deteriorate prematurely and cause premature aging. In the early 1900s, granules were used as an improvement to shingles in order to make them more durable. Their main purpose was to extend the lifespan of shingles. The introduction of ceramic granules followed decades after, and they opened up a wider spectrum of colors previously unachievable. The material from which the granules were derived was altered in order to reduce UV light resistance as well as algae growth inhibition.
