We need to repair a roof leak we are experiencing in our five-year-old home, and are about to replace the ceiling in my daughter's room due to leak damage. The problem seems to occur when snow sitting on top of a roofing vent begins to melt, although I cannot confirm this. I've contacted our insurance agent who thinks it sounds like the roof vent is the problem. He gave me the name of a local roofer who stated the same over the phone but said there is not much I can do about it. I've looked in the attic numerous times and have not been able to pinpoint the roof leak problem. Where do I go from here? The ceiling needs replacing but the leak has to be addressed so I don't end up replacing it twice.
