You should be concerned about roof repair any time that there is a major storm or major weather event, because many compromised roofs are compromised by little defects that are not noticed right away.
It doesn't take much to start a crack in a few shingles so that the next good rainstorm starts a leak in the attic. Check your roof from time to time. Check on the underside of your roof, the ceiling of your attic, and if there is a sign of any water, then you need to look into the repair of your roof.
