What Do Roof Shingles Flapping in Wind Mean?
Shingles are known for protecting your roof from rainwater, snow, and in some cases, hailstorms as well. However, shingles are quite susceptive to the effects of horizontally-propelled winds and rain which can usually happen during storms.
But before we discuss what are the preventive measures in mitigating wind damage so that your shingles will stop flapping, we have to first identify what are tell-tale signs of wind damage and the long-term effects of it.

Flapping shingles can also inadvertently damage your roof by creating holes on the roof sheathing that is exposed to the flapping shingle. These leaks can create more moisture inside the roof while becoming passageways for flowing water and strong wind.
