Dallas Roofing: Article About Wind Damage To A Roof
The most severe forms of wind a home's roof must survive are hurricanes in the tropics and tornadoes further north. In video footage of hurricanes, one can watch the power of the wind peel all the shingles off a roof decking, starting with the eaves of the house and up to the ridge. That suction action is called uplift pressure. Uplift pressure will raise the edges of the shingles on the eaves of the roof, then continue pushing until the shingles lift up and peel away.
Fortunately, most roofs never see that sort of severe wind, but high winds during storms in Dallas can also seriously damage a homeowner's roof. A roof needs to be periodically inspected for wind damage by a Dallas roofing contractor.
Winds flow over and around a roof during a storm. The areas most affected are the eaves, the roof corners and the ridge. This is where the wind flow is the strongest. In these areas, winds can rip away any shingles that aren't fastened down well. The damage starts small and continues to worsen over time. Seasons pass, bringing more storms and more wind. Uplift pressure continues to pull at a roof's shingles until they begin to loosen and come off in the wind. This exposes the underlayment and eventually the plywood roof decking as well.

Shingles located on the eaves, corners and ridge of a roof need to be very well attached, so they can withstand the strong wind currents in these vulnerable locations. Failure to strongly attach the shingles during construction or failure to properly maintain the roof will result in shingle loss and eventual deterioration of the whole roof.
Winds can also warp or curl shingles by breaking the sealant strip and lifting the shingle. Without the sealant bond, the shingle will remain in the curled position, and the next strong wind storm can tear it loose.
Another way winds can damage a roof is with flying debris. Debris can slice into shingles, effectively shredding them. All sorts of debris can be blown by the wind and some may damage the roof or become stuck in the roof vents, blocking the flow of air for attic ventilation. Examples of this type of debris are tree branches and broken glass.
There are many ways winds can damage a roof. However, most roof damage will not be visible or apparent to the average Dallas homeowner. A yearly roof inspection by a knowledgeable roofing contractor is the best plan to reveal any problems caused by wind or storm damage.
