Product description says not for use on a flat roof. Mine isn't flat, but has only a slight pitch. Is the product a good fit for this situation?

Answer: 
I used this on a slight pitch roof and rain comes in when it comes from a specific angle (directly at it). This vent requires a certain pitch for gravity to keep the louver closed. Now I have to tear it out and buy a flat roof vent. I recommend you do the same if you have less than a 15 degree pitch.

Answer: 
The minimum “pitch” is 2/12. This is a 9.46 degree of angle.
If your roof meets this minimum, then you should be okay. If not, then it would not be recommended. For additional assistance, please contact our Technical Support Department at 888-336-6151.

Tim, yes, there should have been a separate connector piece that twists onto the roof cap. This then connects to the flex duct with a zip tie.

The flexible duct easily connects to the fan housing and can be sealed with duct tape. Be careful to make sure there are no leaks and that the flexible duct does not get any punctures or tears.

Can the rvk1a roof vent kit be installed on a wall instead of a roof instead of the Wvk2a wall vent.

My thought is that the roof kit would better prevent drafts than the wall vent kit or is there no advantage to doing this?. I am considering the Broan 684NT vent fan and will want to add a timer switch to control the fan.

Answer: 
No, simply because of the way it is installed. Presumably your house has vinyl/aluminum/wood/et. al siding. The wall vent kit will come with a more appropriate cover piece to match your siding (aesthetics) and also to shed water away. If you were to install this roof vent it would look like a huge black metal eyesore on the side of your house and would almost certainly collect water along siding laps.

Thank you for your question about the Roof vent kit (RVK1A) vs the Wall vent kit (WVK2A). If you were to install the roof cap on a wall, the damper would be hanging open all the time. You could purchase the WVK2A and an additional wall cap, model 885AL. The 885AL is available on the Home Depot.com site. However, you would then have an extra cap that you may/or may not be able to use. You also mention Read More

This is hard as the noise may be coming through the vent and not from it. You may be able to use sound deadening mat from an autosound store. It has a sticky side with peel off covering, cut pieces to fit the inside surfaces of the vent and peel off sticky protector paper and cover all inside surfaces.

Answer: 
Thanks for your question. The answer is a tough one! You could try insulating the actual exhaust pipe. This might muffle the sound a bit. It’s metal. And when rain hits it, it’s going to make some noise. You may want to contact our Technical Support Department at 888-336-6151 and see if they can offer another suggestion. Regards.

Hi helpless, here's an idea. try using Rustoleum Leak Seal flexible rubber coating, sold by Home Depot, to coat the top of the vent. this will dampen the sound of the rain on the bare metal. Hope this helps

Rated 4.2 out of 5 by 67 reviewers.
Rated 5.0 out of 5.0 by DIY First Timer If you aren't afraid of DIY projects, this will be manageable. Do not install on a flat roof. Don't forget a couple of nails, hammer, jigsaw, extension cord, duct tape, roof cement, a mixer, and a brush to apply the cement. April 14, 2016

Rated 4.0 out of 5.0 by Easy complete kit Installation was part of a new roof, so the roofer did the install. After seeing how he did it, I know it will never leak. July 13, 2016

Rated 5.0 out of 5.0 by A handy kit This is a fast way to get a rain proof vent in the roof for your bathroom vent fan. I changed the zip ties that they included as clamps to steel screw drive clamps because I thought they would be more secure. The housing is steel and should be nice and durable. July 2, 2016
Rated 5.0 out of 5.0 by Nice solid roof vent. I have been using these for years I have in the paSt had to purchase these an Industrial Supply house. I have never had a leak or a call back when using this kit. July 1, 2016

Rated 4.0 out of 5.0 by great buy But you need a 4 inch insulated vent hose to vent out a bathroom fan, fyi. To vent a range hood a 4 inch metal pipe is rec. Other than that works great. June 15, 2016
