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 View all Q&A
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.

Q: Is this "roof cap" ul approved for dryer venting?
Asked by:  - 5/4/2015 (Submit an answer)
A: UL does not approve or offer a standard for testing of roof vents. There are no approvals for dryer vent terminations that we are aware of.

On another note, I am aware that the current ICC code cycle will likely add duct termination language to the code that requires the dryer termination hoods' air passage way to not diminish in size and to maintain the 12.5 sq inches throughout the passageway that 4" round duct provides.

Our vents' passageway increases in size some 49%. Other popular vents decrease in size as much as 28%. Hope this helps.

Drying is faster!
I got tired of the ice and condensation of a 30' run through our attic. I researched the Dryer Jack online and installed it easily. Even in the summer, clothes are drying faster and I assume the condensation problem will be gone. I ordered black to match the roof and it is pretty inconspicuous. Good product.

DryerJack - extra clearance design - 4" collar
I noticed the top of the dryer was hot and was running for a long time to fully dry the clothes. I decided it was time to replace the exhaust hose and vent cap but did not want to run it back through the floor and twenty feet through the crawl space in the basement. I decided to go up about ten feet through the roof. I read about the DryerJack and it sounded great. Ordered it, and a couple days later there it was. The install was simple with no problems and the dryer is running much cooler and more efficient. I'm very impressed!

Great design
My Old Vent had a screen in it that Plugged up. This caused moisture to condense in my attic especially when the outside temperature was so cold. The moisture soaked insulation, stained drywall etc. There was so much moisture that it was raining in the attic. This design has no screen and has a duct extension for direct connection. Installer needs to insulate any exposed piping in the attic. I installed 2 of these one for the dryer and one for the bathroom vent. One of the Dryer Jacks had a spot weld that had popped loose, my roofer fixed it for me.

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....
