Wet spot under the floor?

Question

I have a large wet spot in one of the upstairs bedrooms that will not dry . I think I have a leak under the floor . The bedroom sits over a inhouse garage with a finished roof . Can I repair this myself ??? I dont have funds for a plumber

The ceiling is garage is wet Could a pipe be burst and is spraying upwards ??

Answer 1

First find the source of the water.
Water generally goes down, not up.
Is the garage ceiling damp?
Is there an air conditioning unit around?
Look for a condensate leak.
(I hope you find one. Those are easy.)

Answer 2

you cant have a leak under a floor without having a wet ceiling below. Water goes down. I would guess it is coming from a wall onto the floor, I would start there or above. Where's your A/C? Has it been raining?

Answer 3

is there water pipes running to the bed room ? if over a garage try to locate the area and go thru the garage celing,
to locate it, is there a trap door in the garage celing ? if nto you will have to cut a hole,
