10 Oct How Does Wind Damage Your Roof?
Roofing systems are ideally built to withstand the natural elements. Unfortunately, however, when the weather is severe, various aspects of these structures can get torn, blown off, or outright destroyed. This is especially true during times of strong winds. Be cognizant of the potential for roof damages after any windstorm will help you seek timely repairs. So, how does wind damage your roof?
Winds that blow at high speeds cause roofing materials to lift up. Your roof is built in several layers. The base layer is the roofing substrate which is comprised of wood boards or framing, and then covered with several protective materials. The most vulnerable aspects of these systems are the outer layers. Strong winds will often blow one or more shingles off. One these are gone, all underlying materials will be exposed.
Although minor amounts of shingle loss might not seem like a big deal, each missing unit creates an ingress for water. As a result, the underlying materials can be exposed to excess moisture. If this problem is allowed to fester, particularly if it occurs at the start of the rain season, you may end up with substrate that bulges, becomes buckled, or bows. Although minor at first, missing shingles can set the stage for a entire roofing replacement project.
Heavy winds can also tear flashing, cause damage to your gutters and downspouts, and create serious problems at the valleys, where several sections of roofing are joined. In all instances, the main fear is that changes in the ideally seamless and watertight outer surface of roofing will lead the way to moisture problems. Not taking care of these things quickly can result in water spots on your ceilings, pervasive mold problems, and more.
There are even times when wind-related changes create the ideal conditions for insect infestation. Bugs tend to love open, moist spaces at the topmost portion of the home as they create the perfect places for breeding. Thus, if your home has been subjected to any heavy windstorm, you definitely have plenty of solid reasons to schedule a comprehensive roofing inspection.
