another ?

first off let me thank you all for helping me on my other questions they were very helpful. here goes another. the same big client i have been working for has another leak over an office. i have tried 3 times to repair it to no success,i will put pictures up soon!the other day i noticed a plumbing pipe almost filled to the rim when it wasnt raining but it only leaks when it rains and that is the same area. i guess what im asking do you think that when it rains its filling that up and going behind the lead? now this is a flat roof but in this situation shouldnt make a difference.please give me your input because thats the only thing else i see to create a leak.

I was going to suuggest blowing on it! :laugh:

Reminds me of a very hard to find leak. 4 others didn't find it. No holes in the roof, no holes in the pipe flashing. Somebody had cut the pipe off inside, and set it on the ceiling loist. Looked AOK on the roof! :laugh: :side:

copperman Said: is this a vent pipe or a roof drain? Is it filled with water? If its a roof drain then its clogged and needs to be cleaned out. if its a plumbing vent is it cut off and out of service and capped inside. Perhaps its the leak source.
