About to replace 20-year old Responsible tar&gravel roof on my 1952 Eichler with spray-on foam roof. Kitchen exhaust vent damper is damaged and unit needs replacement (8-in. fan in 12”x12” plate in ceiling, 7-ft. above stove, with 8-in. dia. damper above fan in roof vent). Unable to find replacement online or at Home Depot. Modern roof fan exhausts have automatic thermostat (not needed), no damper (to keep heat from escaping from house). Would appreciate suggestions. Would attach 4 photos, if I could figure out how.

I vaguely recall Randy @ Dura-Foam volunteering, a while ago, to suggest a vent with a damper if you email a photo to him.
My kitchen exhaust vent doesn't have a damper and I been wanting to take up Randy's help. Do a search of prior postings on this,
Thanks for Randy’s help. (Neither of us could figure out how to attach or send a photo.)
Problem solved with Panasonic Ventilating Fan FV-08KL1 (with light; FV-08VK1 without light). Electrician had to build 2x4” pine box above 2x6” redwood tongue-and-groove kitchen ceiling to enclose fan and support flashing and vent stack. Fan has 4” dia. exhaust with damper. Existing 10” dia. hole in kitchen ceiling had to be enlarged for 12 1/8 sq. in. fan body. Unit comes with joist mounts, which are useless in Eichler redwood ceiling.
Using a flat metal roof vent, as Randy suggested, also would have solved the problem, if it matched the Panasonic’s exhaust and cleared the additional urethane foam thickness.

I have the same problem. I would really appreciate it if you could tell me where to get the Panasonic Fan and the Electrian who helped with the installation. E-mail to: tim.ma.lsc AT gmail.com. Thanks.
