What Jay J said is good, also maybe the following:
What I would do is get up on the roof and look around and fix any damage. If you aren't comfortable on the roof then hire someone to do it. Most damage that could cause a leak would probably be detectable visually. When the shingles lift up they can crack or crease where they started to fold. Usually, depending on your house design and the wind direction etc. most of the damage is done in one area. Gently try to lift up the edges of each shingle. Closely examine any that lift up, as these were stressed during the storm. Look to see if it has a fold or crease. These cause leaks. When in doubt, replace it. When you are all done then put dabs of black roofing cement under each loose tab to better hold it down. I always do this to the entire roof in new shingle installations as it is recommended on the shingle directions for potentially windy areas etc..
