Hi all. New member here. I'm finding out so many things about our house that it's becoming very frustrating. Typical colonial in New England, hip roof, blown fiberglass in the attic. The problem is the major ice dams forming every winter that have forced me to repair several ceilings and walls throughout the home over the past couple of winters. Anyhow, I have soffit vents and a ridge vent, but I'm doubting if either are installed properly. There is no light coming from the soffit areas in the attic, so I pulled off a couple soffit vents, pulled back the insulation and can now see plenty of light coming through. The problem now is that the ridge vent doesn't look like I think it should. The gap is there but it looks like it's completely sealed with what I think are shingles? I held an incense stick all around the ridge vent and there is no air movement whatsoever. Could it be the builder just didn't cut out the paper or shingles above the opening and I can do that? I'll try to add a photo later when I'm home. As a result of my horrible attic ventilation, I have horrible ice dams on the outside and plenty of signs of moisture inside. Home built in 2002. Lesson for me here is that I did not have an inspection done when we bought it because we had already lived here for 3 years as renters and my agent said I probably would have noticed any issues after living there so long. Anyhow, any advice is greatly appreciated. Thanks!
