This is one of the only vents you should use for a roof vented fan. Do not use plastic vents designed for dryers.

Good Roof cap that was easy to install but attaching the duct to the flange was tricky because the flange is so short. If they had made the flange an inch or two longer it would have been a breeze to install.

Great vent cap for a microwave, just needs a couple of inches added to the pipe hook up. Great quality.

This worked great for what I needed. Exhaust vent for a 6" shower fan.

Roof cap is well made with a very good back draft damper and bird screen. BUT, for existing roof applications - The duct attachment collar is only about 1" long and does not protrude through the roof sheeting. It's almost imposable to attach an insulated flex duct after installing on the roof. I would suggest anyone buying this also buy a 6" dia. collar extension and secure it to the cap's collar BEFORE installation to the roof. Don't make the extension any longer than necessary. BROAN needs to add a collar extension to correct this. I would then rate it 5 stars.

I have a low pitch roof and was searching for a kitchen exhaust roof cap that angled down as much as possible to prevent driving rain from entering the vent. I installed the cap on a Friday and we got hit with a blizzard on Saturday. I had the ceiling open so I was able to watch it for 4 days and all was well. I did tape a 1" electrical box knockout slug to the flap cap as a prior reviewer suggested as I too thought it too easy to open. The exhaust fan is installed and running venting well. Broan knocks out a nice decent gauge piece of sheet metal. The Home Cheapo or Blowes stores only carry cheap flashing gauge vents that would require an equal amount of aluminum tape to keep them water tight.

Exact solution for our island range hood vent on roof. A little short on the interior protrusion for connecting the duct work.
