I recently just purchased a home and I'm having a few water issues I'm hoping someone can help with. This home was built in about 1950 and had a new shingle roof put on 2 years ago. Recently we had extremely heavy rains for the area (3-4 inches in an hour, followed by several inches over a couple of days). Shortly after the rain, it snowed a couple of inches and that snow began to accumulate on the ground and roof. Everything was fine on the days during the rain, but the morning after the snow (on the shady side of the house), I noticed staining on my living room ceiling. It rained again today, and I went up in the attic during the rain and could not find a leak anywhere, nor see any light from the exteriror. The insulation in the house is very old, and the gutters need to be cleaned (so I'm working on that..I know thats an issue). I'm wondering if an ice dam formed as a result of the snow, since it handled the rain just fine. Another issue is that in the basement, some water (puddling) came in, so I thought it could be condensation, but I'm ruling that out as it seems to be in one corner of my house, far away from the basement entry. Does this seem consistent with an ice dam? Also, an interior window seems to have water pooling around it in the mornings (below some condensation) even when it doesn't rain. Could this be due to my humidity levels being too high in the house? I caulked the seals around this window, so unless I missed something I don't think they are leaking. Thanks!
