Short answer
When your roof leaks during rain, move valuables, catch the water with buckets, and poke a small hole in a bulging ceiling to drain it in a controlled spot. Take photos for insurance. Do not go on the roof during the storm; once it is safe, a roofer can tarp it and find the source.

Protect inside
Move furniture, electronics and rugs; use buckets and towels.
