Will a squirrel be able to get in attic via this roof vent?

Asked by DTD October 11, 2020
4
Answers

I think the bird screen (galvanized steel) alone would keep squirrels out. We installed this vent on a roof about 10 feet higher than the surrounding surface. We have dozens of ground squirrels around the house. We have had no problem with squirrels being able to enter the vent. I am doing some hunting to thin out the squirrels who are doing other damage to flower beds, inside the garage, etc.

For use as an exhaust fan discharge, bathroom or otherwise, it meets the California Mechanical Code. It has the required backdraft damper. It would not meet code for a clothes dryer exhaust vent if the flexible duct is concealed and the screen would have to be removed since none is permitted for a clothes dryer.

I am putting a new addition onto my existing home. Do I install this prior to shingles or after?

Asked by Brandon February 19, 2020

Answers

It should be installed as you apply shingles on a new roof. This would be just like any plumbing vent pipe flashing. You probably will want to cut the circular hole in the roof sheathing in advance of roofing.

Specifications state not to use for dryer vent

Asked by alan February 17, 2020

Answers

Hey Alan, Cannot answer why this product shows up under dryer vents; perhaps the search is keying on the word "vent". My guess is this item is not suitable for a dryer vent since it may easily become clogged with dryer lint presenting a fire hazard. Plus dryer vents are way cheaper!

Can you use this to vent a garage without connecting it to anything?

Asked by Teresa September 14, 2019

The roof vent kit is designed to go with an exhaust fan. The damper on the roof cap will be unable to open unless air is being forced to open it.

I believe if you have a 3" outlet on your fan instead of a 4" like the tube provided. It is meant to fill the gap between the two.

Pretty decent vent kit

This would be a better kit if instead of zip ties, it used either spring clamps or screw clamps to hold the vent tube in place. Taping it with good aluminum tape is absolutely essential. That’s the only reason I knocked it down to 4 stars. It would also be good if the vent tube was insulated. I chose to insulate it, with a wrap of Reflectix bubble insulation. 16” wide Reflectix exactly wraps the 4” tubing when it’s pulled out. It still remains relatively flexible when wrapped. The vent itself is pretty decent, though, and as roof vents go, it was relatively easy to install. It’s small enough to be relatively unobtrusive, but is large enough to do the job.

Roofing contractor installed vents and we connected hoses to fans. Contractor would have installed pipe stacks but we prefer the vent kit style. Easyzip ties to attach hoses and foam strips extras got used to adapt hose to an older fan with a smaller diameter exhaust housing.

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.

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.

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.
