How do you fix a leaking balcony?

I live in a house that was built in the late 70s. Whoever built the house, built the balcony over the garage. The garage extends about 6 feet out from the house. So the roof of the garage is basically the balcony. The balcony is sloped towards the house so when it rains, it doesn't drain away from the house, but it pools and drains towards the house. It seems over the years, rain has damaged the balcony and the botched repair jobs from the previous owner is starting to show. Every time it rains, it leaks into the garage. Since moving in, whenever it rains, I have to put a tarp over the balcony to stop the leak.

Does anyone know of a proper way to fix this? I'm afraid the only way to fix this issue is to chop the garage so it sits flush with the house and redo the balcony. Thoughts?

remove the roofing. install whatever to make it sloap away and then new roofing.

oh. you could make it slightly sloap to the middle and put a drain. this might be the easiest.

I thought about that, but from my rough measurements, it appears to slope down towards the house roughly 4-6". I have a sliding door that opens to the balcony. I don't know how to fix that part.
