[RE-wrenches] Solar Roof Jack

[Daniel Young]

Just curious if there is a reason you don’t just cut the roof vent off above the flashing?

It is allowed by the 2018 IRC and later in section P3103.1.3, solar modules are explicitly called out as a reason to cut the vents.

https://codes.iccsafe.org/content/IRC2021P1/chapter-31-vents#IRC2021P1_Pt07_Ch31_SecP3103

Not all states adopt this of course. Ohio for example redacted this from the code version they have adopted. So maybe that is the reason. If not, there is your code reference if needed.

We just used a few of these recently. Seemed easy enough and plan on using more on an upcoming project. We had easy access to the vent in the attic which probably helped. Only complaint was that I was worried about the vent cap (provided) blowing off and eventually having debris get in there and get stuck in the horizontal run on the roof. I’m not a plumber though…so maybe I’m over thinking it. We put a screw into the cap just in case
