I was working at a house the other day and noticed big icecicles hanging from the gutters. I went into the attic and found insulation in the ceiling from below with wood covering the joists. The roof only had about 1″ of fiberglass in it.
The roof has all the snow melted off until it hits the soffits where it’s freezing. The attic is heated on one side where there is a dormer. The unfinished side was also about 50 degrees.
I was going to put styrofoam baffles in the roof and put r19 over that. I figured that would allow the cold air from the soffits to stay under the sheathing and keep the roof cold. Does this sound like it would prevent the roof from melting and causing icecicles?
