I've always had ice dams below my skylights in my 9 year old home and have always kept an eye on that part of the house. However, this year, I have them on just about every side of the house and water is seeping in on one portion of the house. I am working on having the damage assessed and having repairs made but have a couple of questions about this. 1) We have had record snows this year (approaching 100")and have had several storms where rain on already heavy snow was followed by cold weather so icing under the snow was pretty much inevitable. I also had drifting on the roof and some ares are still under more than a foot of snow while other areas are finally clearing off. I have a ridge vented home and noticed the snow had covered most if not all of the ridge. Is this vent being mostly blocked a likely explanation for the damming I had this year? Is installing a power vent something that would make sense in this scenario? And what is one supposed to do to keep the ridge vent clear under these circomstances? 2) I do not want to go through this again in the future. Who is best equipped to evaluate my situation as far as insulation, heat loss and venting goes? A roofing contractor, one of the home improvement outfits or who? Thanks, Dave
