Wet insulation is inefficient â but more immediately, it can be a hidden risk. When a roof leak leads to saturated insulation, that insulation almost always needs to be replaced. Wet Insulation Is Bad for Your Roof, Your Building, and its Occupants. Insulation sits just below the roofâs membrane. When a leak allows water to seep in through the outer membrane and saturate the insulation below, that moisture can deteriorate the roof on multiple fronts.
A hot roof is a properly sealed unvented attic, instead of a traditional vented roof which consist of an insulated attic floor and open soffits where air enters and then leaves through the top of the roof.pray foamed attics have foam applied directly to the roof decking, and the attic space isnât ventilated. The lack of ventilation is why they are called hot roofs. In a standard insulation system, ceiling insulation reduces the transfer of heat from the attic to the living space (in the summer).
