Worn out pipe collar.
This is one of the main places for leaks on residential roofs. What happens is the pipe collar becomes brittle and starts to crack and fail, many so called professionals will tell you that they can just patch around it with some sort mastic, but what you should really do is replace it.
In The Field
It is very possible that your roof can be leaking somewhere in the middle. Look for worn out granules, nail pops, or broken shingles
Chimneys
Chimneys contain four different types of flashing. All must be right or you will have a leak. Plus, the counter flashing that goes into the brick mortar joint must be right. A hairline crack above the flashing can allow vast amounts of water to run behind the flashings. Look for soldered corners of flashing that might have broken or have holes. Do not use caulk to repair these flashings!
Ice Dam Leaks
These leaks can happen even if everything on your roof is just fine! Ice dams block the natural flow of water down a roof. The water begins to back up under flashings, shingles, tar paper, etc. Once water begins to flow into the house, it can drip for days. The only means of prevention is to install membranes under the roofing. The membranes won't stop the ice but will stop water leaks if installed properly.
