The extent of the hail damage to your roof during a storm depends on the size of the hail and also the strength and direction of the wind. Damage to your shingles may not be visible at first but may eventually lead to leaks or water damage to the interior of your home. If you are concerned about the integrity of your roof following a strong storm, it may be in your best interest to have an experienced roofing contractor inspect your shingles to assess the need for repair or replacement.
How Hail Damages Your Roof
Asphalt shingles are the most common roofing material damaged by hail. Ceramic granules are embedded in shingles to protect it from the sun's rays.Granule loss is common during the lifespan of all shingles, but is dramatically accelerated by hail damage. When hail strikes your roof, it creates soft spots on the shingles and loosens the granules. The loosened granules may begin washing away immediately, or fall out much faster than an ordinary shingle.
After a hail storm, look for loose granules in your gutters or at the bottom of your gutter downspouts. This indicates that the protective coating of your shingles is wearing away which can lead to bald spots and cracked or curled shingles, and create the risk of water leaks. Hail damage to your shingles voids nearly all manufacturer's warranties. It is important to detect hail damage quickly to ensure your insurance company can provide proper coverage for any repairs needed.
Wind Damage & Your Roof
High winds can also cause damage to your shingles by lifting the shingles and even ripping and tearing them through the nails. In some cases the shingles may lay flat again much as it did before, making the damage hard to detect. Once a shingle is torn it is no longer watertight and jeopardizes the integrity of your roof.
