In this video, I try to explain: what makes a hybrid roof how a hybrid roof differs from the standard cold roof or warm roof constructions, which are widely used in the building industry the different ways you can form a hybrid roof. A hybrid roof is a mixture of a cold roof and a warm roof construction. If you are constructing a cold roof – If you totally fill the void between the joists with insulation, it’s a hybrid roof. You don’t vent the roof, it’s a hybrid roof. Or you don’t use any insulation at all, it’s a hybrid roof. Or a warm roof – I’m often asked if some insulation can be put inside the roof and some outside the roof. If you do, it’s a hybrid roof.
