Finished Attic No Ventilation

I hope someone can help us and the 2 contractors who have diagnosed the problem as nothin to do now.

Finished attic no ventilation.

However if moisture is able to enter the unvented attic space it may lead to roofing panel issues. Unventilated attics can help to mitigate energy loss through leaky ducts or ceiling fittings. A combination of air sealing and insulating the attic floor while providing ventilation considerably reduces the potential for condensation as warm moist air is less likely to enter. Without properly insulating your finished attic room will also be cold in the winter.

Without properly ventilating the roof your finished space can be just as unpleasant as an unfinished attic. To meet all three goals insulating your finished attic ventilating the roof and maximizing headroom use a combination of dense batt insulation rigid foam sheeting and air chutes. Gable vents may circulate air through only a small percentage of your attic. Too often mechanical ventilation ducts from bathrooms kitchens or laundry rooms deposit warm moist air into the attic instead of outside the building envelope.

Since parts of a finished attic are usually very close to the roof insulation often blocks proper ventilation that is needed under a roof structure. The energy savings touted by unvented attics can be as high as 20. Without baffles blinders that prevent outside air from crossing over the vent a ridge vent may create almost no ventilation at all. Most codes require a specified minimum amount of headroom and it s tough to meet this requirement when insulating a finished attic especially since most.
