After a hail producing-storm, I often hear homeowners remark, “I can’t see any damage” or, “My roof doesn’t look that bad.” Don’t be fooled. Hail is insidious, often causing very subtle damage initially. While the visible effects evident after the storm do not always pose immediately risk to your structure, the harmful repercussions continue long after the storm has passed.
Let me explain why. The granule top of shingles are manufactured to protect the asphalt base from the sun and the elements. Under normal conditions, shingles are designed to last for very long periods of time (typically 25 years or more depending upon the product) and granules are lost very slowly. Each hail strike to a roof however, causes a bruise on the shingle and instant granule loss. Though seemingly innocent, this bruise and the resulting granule loss causes underlayment exposure that greatly expedites the degradation process, causing rapid roof deterioration and significantly shortening the lifespan of your roof. As this process continues, UV rays will destroy the integrity of the asphalt base, eventually leading to leaks, water damage, wet insulation, mold, and even collapse.
So what’s the urgency? Since most insurance companies only allow a maximum of one to two years to file a claim, the harmful effects and often catastrophic damage that follows a hail storm may appear too late to protect your investment. This is a costly mistake as your roof is undoubtedly one of the most expensive and important features on your home or business. Have your roof evaluated by a professional after a hail-producing storm to ensure your roof maintains its integrity and longevity.
