A bit of a problem...any advice?

I came home from bible study last night to have water coming through our garage ceiling. Yes, we have a leaky roof. Our 3 year old house has a leaky roof? What in the world is going on? We finally got some good Georgia rain last night and our roof has to leak. Brad and I have been praying for rain and last night we were praying that it would stop! Thank goodness it is not coming into our house, but it has still caused a huge mess in our ceiling and wall. We found in the attic where the rain is coming in at around 1 am when it was still raining! So, does any one know a good roofer in Atlanta that is trust worthy to give us a good estimate? Any good stories about water leaks out there?
