After replacing the exhaust fan in the main bath and venting it to the eve where there is a fresh air vent to ventlate the attic, I have been looking at other houses, and have seen very few that vent out the roof thru a special vent, I wonder if those without a roof vent are venting directly into the attic.
I intend to install a roof vent when I re-shingle the roof this summer, I am concerned about the roof vent being blocked when it snows.Sometimes there is as now 10 inches of snow on the roof. I have alot of insulation in the attic and the snow remains on the roof along time due to the insulation.
