What is best way to upgrade insulation in sloping ceiling with rubber roof directly above it?
I’m about to take out a small room that encroaches on my living room to enlarge my liv rm/dining rm area. The living room is in an addition to the building with a gently sloping rubber roof directly above it. This room is always cold, the walls and ceiling are not very well insulated. We will have to cut open the ceiling to place a support beam down the middle perpendicular to the joists. While we have the ceiling open, we are thinking it would be a good time to put in additional insulation in the roof. Right now it looks like the roof is vented under the eves but probably not along the top. Would blowing in a solid pack of cellulose insulation be the right option for us? We have to shovel the roof occasionally when we get a heavy snowfall and sometimes the rubber roof has gotten damaged, so I’m a little worried about mold with the cellulose. If we blow in a solid pack of cellulose will roof still need to be vented? Can we get the cellulose packed tight enough with a blower rented from Home Depot or is this a job for a professionals?
