Trapped heat and moisture can raise energy costs, create ice dams, and damage roof system components. In extreme cases where temperatures reach 150° F (65° C), damage can occur to the attic’s structural integrity as well as to nearby property.
Condensation that forms inside attics can be caused by moisture from household appliances, such as washing machines, dishwashers, bathtubs, showers, and driers that are improperly ventilated through the roof. In some cases the condensation can be severe enough to be mistaken for a roof leak.
Proper ventilation will remove moisture and heat from the attic and keep your attic dry and cold.
