Hi!My little house has a hip roof, which means the rafters in the corners come together in an inverted V about three feet from the attic floor. In each corner are two of the soffit vents. I want to have insulation blown in over the 40 year old 6 inch batt insulation, but need to have the soffit vent chutes installed such that the airways are not restricted. Contractors through a local npo installed some carboard vent chutes, but tilted so the corner of the cardboard aligns with the rafters, closing the V nicely. Not nailed shut, but air must leak through an envelope-like slit. They off-set two of the corner chutes slightly, allowing a little more air flow but not much. Anybody have tips for vent chuting this V construction for maximum air flow from the soffit vents? I already have some problems with ice dams, have a ridge vent, two gable vents and a couple of jacks, but need those soffit vents to get air in. Once the insulation is blown in next spring, retrofitting the chutes will be well-nigh impossible, but I can tinker with them now. Thanks a million, best, M.
