Additional Description:

This medium sized Galvalume® roof cap has a plate (flange) size of 12” wide x 14” and the structure is 6” wide x 8” and about 8” high.  It has a 4.12 inch diameter collar that excepts typical residential dryer exhaust conduit.  Per building codes, there is no screen in this vent as it is exclusively designed for clothes dryers.  Unlike other roof vents this vent features a unique light-weight damper that is curved which increases the efficiency dramatically.  The final opening is 65% larger than the round pipe portion.  By far, this is the most efficient roof vent on the market. 

The collar penetrates the plate about 1.25 inches and is sealed to the plate with a silicone bead.  It will work on a flat roof as long as there is no chance of standing water greater than 1” and sloped roofs up to 12/12.  Note: Not recommended for use with a high-profile roof tiles like "S", Spanish S as there is only 5 inches between the opening and the bottom plate.  Nest building within would be doubtful due to the slope and shape of the damper.  This vent is proudly made in the USA.

Professional installation is recommended.

Not recommended for flat roofs where the water level could exceed 1” due to the inability of the roofs’ drains to dissipate the water.
Not recommended for for bathroom exhaust fans with less than 70 cfm output.  
Questions and Answers
Q: What is considered a "high snowfall zone"?
Asked by:  - 6/4/2014 (Submit an answer)
A: High snowfall region would be where 12-24 inches of snow is typical or common. This taller design offers a "hood" of the exit point so that at initial dryer start-up, the hot air has a chance to exit and start to melt the snow blocking the exhaust.

Q: I am concerned about correct seal on flat roof. Do you have recommended procedure for attaching unit to roof and sealing it against rain, etc...?
Asked by:  - 1/3/2015 (Submit an answer)
A: There are so many issues, types of material, job conditions, codes, that it is difficult and not wise for us to pass along instructions for correctly installing the DryerJack. Many in the industry prefer a curb style mount over the flat flange mount. The curb style's one big advantage is that it could be easily replaced, and some feel that the likelihood of a leak is less with a curb style vent.

We've had people cut off our flange completely on the 466, and mount it to a stubbed up metal round pipe, say 10" over the deck. See this link for our curb style DryerJack.

Recently I discovered our dryer, which was vented thru the roof, was using the wrong vent. It was the kind used to vent a exhaust fan and it was completely block with lent and the piping had come apart and was venting directly into the attic(what a mess). This was a extreme fire hazard. I did some quick research and decided on the DryerJack, which was easy(for me) to install and works as well or better than promised. I would recommend it to anyone!!!! Thanks much....

Well designed, well made
We bought the Dryer Jack to be used as part of a small remodeling project. Re-routing our dryer vent through the roof over our garage was the best option. After a lot of research we chose the Dryer Jack. It is very well made and the design is ingenious! Works very well. If you need to vent your dryer through the roof...this is the only way to go.

Dryer Jack Install
Hired a roofing contractor to install, when old T vent was removed it had a screen in it that was plugged with lint. New Dryer Jack flow like a charm, clothes dry quickly and hopefully no lint built up. A great investment!

Very happy with the product. Installation went well. Seems like a durable, quality product. The roofer who installed it for me was interested to know about it for his own use.

Product was exactly as described. It arrived quickly and is well made. I got the painted version and the paint appears to be very good quality. Installed fine, and works great. I forgot to take into account the vent connection is perpendicular to the flashing plate, and had to add a twisting 45-degree coupler to match the vertical dryer vent. Would recommend to a friend.
