Hello, I just found this site, and have a question that has been bothering me. I have a older home that was built in the late 40s or early 50s, not sure of the date. In my attic I noticed that the insulation was below the rafters, what was there was cellulose. I had a company come in a blow fiberglass in the attic over what was there. I cant remember the exact r value they added, but I think it was r42 it is very deep now. What my question is, I was under the impression that when it snows that if a home does not have good insulation that the snow leave the roof very fast? Well it has snowed 2 times now, and the snow is gone as fast now as it was leaving before we added the new insulation. Do I have some kind of problem, or could this be ok? I hate to think that all the new insulation was not a help? Thanks for any answers you may give!
