All the screws are sealed on the outside with silicone sealant. Also, a bead of silicone on top that support piece that twists around the pipe. Pipes are installed in proper direction, so its not leaking in the pipe assemble joints. Every pipe seam in the garage drips water when it rains.

I cant figure out where it comes in. Id rather not get up there with a hose. It only leaks when there is a lot of rain. Either very hard rain or just a long rain.

Ideas?

Is that black pipe??

It should never be used outside if it is black pipe. Very poor installation.

Tend to agree with the above. You used the wrong materials for the job. I’m all for saving money but some things need to be done the right way for performance and safety. Black indoor stove pipe outside isn’t it

Redo this whole chimney. I wouldn't worry about the water, I would worry more about burning the place down.

At this point its prob half water logged so wont burn..lol

Triple wall stove pipe and a proper roof flashing are not very expensive and when done correctly will not leak...even with metal roofs.

There are so many things wrong with that installation that I don't know where to start.

To answer the original question, it leaks because it's pipe made for INDOOR USE ONLY being used outdoors.

The pipe is also installed upside down...

Then you might want to read up on codes and clearance from combustibles...
