Is there any reason not to install a bathroom fan roof cap very near
the edge of the roof, about 1.5 feet from the rain gutter? There is
no soffit on this side of the house. Because of the location of the
bathroom fan, the closest, most direct venting would be if the roof
cap was near the edge of the gutter. I have a ranch style house, with
gutter all the way around if that helps.
This is at the rear of the house, so aesthetics isn't an issue.
Best advice would be from your building code people. In small towns
like ours it is apparently OK as I have seen a few vents for plumbing
and fans close to the gutters. Keep in mind that that location has the
heaviest water run off from the roof and thus needs extra attention to
flashing, like major size increases, since the low slope (4 in 12 or
less) of the ranch roofs make ice dams and leaks likely. HTH
I used to live in Holland, MI, until I got laid off. Good memories!
I'd move the penetration up higher on the roof. You're just going to run
a piece of flex duct (I assume), so use a fishing pole to pull the end
of the duct back to where there's enough headroom to work from inside
Did I mention checking the local building code? Call the city and ask to
speak to an inspector. They'll answer your question in no time.
