Wind does not move a roof uniformly. Corners and the roof’s perimeter can be susceptible to higher wind pressures, while the center might have lower stresses. Because of this, most wind damage to a roof starts on the edge. Anywhere the roofing material is even a little bit loose, the wind can get below it and push it up, thus giving the wind more to grab onto next time and creating a chain peeling effect. This type of wind damage can start very small but continue to grow over time through repeated exposure to wind.

Once the whole insulation corner is exposed, the rain gets in and starts to cause leaks and water damage. Homeowners can avoid this type of wind damage by making certain materials on the edge and corners of their roof are strong enough and in good condition to withstand high winds.

Significant wind events also move debris which can make its way onto your roof. Shards of glass, tree branches and other debris can sometimes be more damaging than the wind itself. When inspecting the roof after a wind event, investigate what might have blown onto or across the roof. Also, it’s a good idea to check your gutters and downspouts as debris can easily clog them and create other headaches down the road. Keep trees trimmed and away from your roof. Tree branches touching a roof will scratch and gouge roofing materials when the wind blows the branches. Falling branches from overhanging trees can damage or even puncture shingles and other roofing materials.
