Apparently the tree that fell on our roof last winter did more damage than we realized. We had our first light snow of the winter last night, and as we were going to bed, we noticed a loud dripping that didn't sound like it was coming from outside. Lo and behold, the ceiling was leaking water. So we set up the buckets and went to bed.
So this morning we rearranged the furniture, and Bryan found where the water was getting in. We talked about our options, and decided we'd try to do a basic patch job, and save the major reconstruction for next summer. So Bryan bought a bucket of Black Jack and sealed everything up. We hope. Time will tell.
