Asphalt shingles are manufactured with a seal tab, this tab can become compromised during high winds. Damage that may exist could be displaced shingles, seal tabs lifted, gorged shingles. Most of the time these damages are not visible from the ground, that's why it so important to have your roof inspected by a professional roofing company who understands these types of damages. If any of these "wind effects'' have occurred you may be due a complete new roof replacement.
