I see my roof in my neighborhood is one of the first to lose the snow on the roof. I am thinking I might need some more insulation. I have a Brick ranch single story house that was built in 1965. I set my temperature at 69 degrees, temps outside this past week have been in the low 30's in day and teens at night.snow fall was 3 inches on Sunday and most my snow on roof was gone on Wednesday. .Have you had this done and what price did you pay ?? Ball park is good ? Did you save on gas or electric bill ??
