Rated 4.0 out of 5 by 43 reviewers.
Rated 4.0 out of 5.0 by Good value, easy to install I bought two of these kits as I had two bath fans which were exhausting to the attic. They had excellent instructions and went in easily. Only suggestion would be to include the sealing tape in addition t the tie wrap for a code complete kit. One installation as a straight shot from the fan was pretty close to the peak of the roof. This one catches the wind and so makes a bit of flapper noise on a windy day. Maybe an added note to the instructions that this may no be the best place, and a little angle on the vent line is OK.

Rated 4.0 out of 5.0 by Roof vent kit The roof vent kit is very easy to install. The instructions are easy to follow as long as you have some basic tools. It took about and hour to install. The only thing you need to purchase in addition to the kit is some roofing nails and roofing caulk. Once installed it connected directly to my bathroom fan with no hassle. The only recommendation is that I would use insulated flex hose and not the uninsulated one in the kit since the attic is a cold zone and you don't want condensation to build on the hose during the winter. It's easy enough to get insulated flex hose. I would use this product again. January 31, 2011
Rated 1.0 out of 5.0 by Easy install - looks good - doesn't last, rusts out Easy install if you have some basic skills. Low profile so looks good on the roof. Work well, but noisy in the rain. Had 2 of them for 2 bathrooms and both rusted through and started leaking within 8-10 years. If you want something you won't have to replace every 10 years find one in aluminum or maybe a sturdy plastic. Unfortunately, these just don't last very long. April 18, 2015
Rated 5.0 out of 5.0 by Great Roof Vent Kit I saw a episode of a home improvement show that featured a roof vent just like this being installed, which as a procedure was fairly simple. The only thing which this kit does not have that would make it even better would be an insulated vent hose. Luckily, Home Depot sells those as well, and we bought that from them as well. Venting your Broan exhaust fan out through the roof is very important to keeping mold from growing on the underside of your roof. June 18, 2010
Rated 1.0 out of 5.0 by Conflicting information? This kit comes with flex pipe. Q & A number 6 from Broan customer service on this website advises to use rigid ductowrk when connecting to exhaust fans. Considering that this product is advertised as an bath and ventilation fan, can you enumerate as to why you include flex pipe with the product? May 30, 2014
Rated 2.0 out of 5.0 by Roof vent requires a good installation. The roof vent was installed by a professional. I had to hire a roofer to properly seal the vent. Be careful when installing through the roof. When it rains, the vent is very noisy. It should have been built with a sound barrier November 4, 2014
Rated 5.0 out of 5.0 by They work well and are stylish I was looking for new roof vents for my two bathrooms and found these, which look really good and also come with the flex duct & other accessories. I was getting my roof replaced at the time and these vents worked out well. It's also designed to prevent back flow. June 17, 2014
Rated 4.0 out of 5.0 by Great value - but needs a better parts list Great overall product, especially considering what you get for the money. All materials felt of high quality, and the bird screen and backflow preventer are an extra bonus. This roof vent is also fairly easy to install, with a nice set of instruction on how to properly seal the roof penetration. Two cons are as follows: 1) The roof vent connector piece is not well represented on the box in the "parts included" section and as such it was a bit confusing how to properly install it. It is also quite a fit (had to bend it somewhat) to get the roof vent connector to fir inside the roof vent. 2) As a "kit" which is likely primarily used for bathroom vents, it would be great to have the duct come insulated. Instead it is just one more step to wrap the duct with insulation and foil tape...a minor annoyance but all the same a contributor to only four stars. July 10, 2012
