What Is Wind Damage
Wind damage is caused by the uplift forces due to aerodynamic effects: ridges, windward roof corners, eves, rakes are the first places to suffer damage. Damage caused by wind is usually in the form of missing shingles and underlayement, as well as structural. Wind exerts positive and negative pressures as it flows over and around a structure. The areas of greatest uplift are at the windward corners and windward eves; these are the areas where the wind damage often initiates. Once this process starts, it has a domino effect: roofing material starts to loosen as uplift occurs and the materials start to break away and are torn from the structure. This exposes the structure to water infiltration, mold and interior damage as a result.
