Wind damage on PVC and TPO roofs does not always show up as a tear. Very often, the early sign is movement: a lifted edge, a seam that starts to separate, or a corner detail that looks slightly different after a storm.
That is why wind inspection has to focus on patterns, not only on obvious holes.
If any of those signs appear after a storm, the roof should be checked more closely before the next weather event.
Wind damage usually starts small but expands fast. Once the membrane edge opens, wind can get under the sheet and increase the movement. That means a small defect can turn into a much larger perimeter problem in a very short time.
After wind, focus on:
If the roof has equipment zones or service traffic routes near the edge, inspect those too. Wind often reveals weaknesses that were already there but not yet visible.
If the signs are minor, the repair may stay local. If the edge movement is repeated or the termination line is unstable, the contractor should treat it as a perimeter repair issue, not a simple patch job.
For owners, the key point is simple: if the roof shows wind damage once, it should be watched carefully after the next storm.
