I’m new here and have searched all over but can’t seem to find a definite answer on this. The vent termination is extremely close to the bottom of the eaves. It doesn’t seem right to me but I can’t find anywhere that has the exact clearance that is needed, or perhaps it’s fine?
No window. That was decorative trim. No vented soffit either. I’ve just never seen the eaves so close to the vent stack like that. Seemed odd so I wasn’t sure.
Open vent pipes that extend through a roof shall be terminated at least 6 inches (152 mm) above the roof or 6 inches (152 mm) above the anticipated snow accumulation , whichever is greater, except that where a roof is to be used for any purpose other than weather protection, the vent extension shall be run at least 7 inches.
Robert, are you mixing heating vent terminations in there?

Afternoon.
Let me double check, Larry.

I dont know of any code that gives a clearance requirement ABOVE the vent. As long as it isnt blocked, and can pull air in, I wouldnt call it out.

Thank you!
If I’m reading this correctly, you just can’t have anything literally covering any portion of the hole.
P3103.1.3 Roof Extension Covered
Where an open vent pipe terminates above a sloped roof and is covered by either a roof-mounted panel (such as a solar collector or photovoltaic panel mounted over the vent opening) or a roof element (such as an architectural feature or a decorative shroud), the vent pipe shall terminate not less than 2 inches (51 mm) above the roof surface. Such roof elements shall be designed to prevent the adverse effects of snow accumulation and wind on the function of the vent. The placement of a panel over a vent pipe and the design of a roof element covering the vent pipe shall provide for an open area for the vent pipe to the outdoors that is not less than the area of the pipe, as calculated from the inside diameter of the pipe. Such vent terminals shall be protected by a method that prevents birds and rodents from entering or blocking the vent pipe opening.
