Abstract
A vented building includes a structure with a roof, the roof including a sloping support surface having an opening therein and roofing materials on the support surface. A housing with peripheral walls surrounded by and connected to a flashing is mounted on and in alignment with the opening in the support surface such that the flashing is supported by the support surface and covered by roofing material. At least one opening in the housing is spaced above the flashing, and a gasket is located within the housing and sealing the inside of the housing. A pipe extends from within the structure to the gasket with the gasket sealingly receiving the pipe. Thus, the pipe is provided with a vent through the opening in the housing to vent the pipe to the exterior of the building through the building's roof while preventing the ingress of precipitation to the interior of the building.
