My house has developed a roof leak. Asphalt shingled roof, approx 7 years old and in good shape otherwise. Leak is in the rough vicinity of (actually down about 4 feet and over a bit) from a bathroom fan hood.
I've had a professional roofing contractor over to repair the problem. He came during our first real rain of the spring (when I first got the leak) and patched some areas with "wet seal" while it was very wet and cold out. He assured me that didn't matter.
5 weeks later (last week) we had a TORRENTIAL downpour. I checked the attic about 8 hours later, and my towels and plastic (protecting the ceiling and insulation) were definitely damp. Not sopping wet as anticipated. Also of note is this "wet seal" product (initially black) is now turning a brown/green colour...I'm not so sure thats normal.Any ideas on where/how to look for this leak? Short of waiting for a good downpour and taking the day off to send my father into the attic and "watch" for the water (which is very difficult in this particular attic), what else can I do? Is the repair going to be hit and miss? I'm not sure i fully trust the garden-hose-soak method, as I can't see it being wide-spread enough to duplicate a good rain-soaking.
Any roofers out there with some experience to share? Please? :)

I'm told that the "wet seal" product really doesn't work very well when applied in the cold and wet. Also considering the leak seems to have been slowed up, I think we're on the right track...but how do you know?
