The DryerJack Model DJK486 roof vent termination is specifically designed for dryer venting. Its precision-tuned design creates no resistance, giving a level of performance previously unavailable in the industry. This vent features an industry-first curved damper that deters nesting birds and critters. Removing a total of four rivets makes the front panel removable to provide access for cleaning and maintenance. 

The sturdy 26-gauge Galvalume® steel housing is built to last. This extra clearance vent is best suited for medium snowfall regions, sloped roofs with flat profile cement tiles or other composite shingles. Does not provide adequate clearance in height for "S" or Barrel Tile roofs.

  • Radius corners to minimize injury
  • Creates no back pressure
  • Complies With IMC 504.4 & IRC 1502.3

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 9” high. It has a 4.12 inch diameter collar that accepts 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 lightweight damper that is curved, increasing 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. 

For flat roof installs, we recommend a installing our DJK486U (curb style) over a raised curb. 

The collar penetrates the plate about 1.25 inches and is sealed to the plate with a silicone bead. It will work on sloped roofs from 2/12 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.  Bird nest building within would be doubtful due to the slope and shape of the damper. This vent is proudly made in the USA. 

Galvalume: A patented alloy of barrier-resistant aluminum and corrosion-fighting zinc gives Galvalume its superior corrosion resistance. Most Galvalume substrates feature an alloy that is 55% aluminum, 43.5% zinc and 1.5% silicon. Tests have proven this alloy superior to the zinc-only coating used in regular Galvanized sheeting. Additionally, it is Acrylic Coated, coating designation AZ-55. 

Complies with 2017 code M1502.3.1 (Exhaust termination passageway size). 

Professional installation is recommended. 

DIY'ers, we recommend Polyurethane Roof and Flashing Sealant. 

Not recommended for for bathroom exhaust fans with less than 70 cfm output.

Best design

by Leo| 9/22/2013 12:00:00 am

As a contractor, I have installed many types of dryer vents. This is absolutely the best roof dryer vent I have found in 30 years. Very well made with heavy gauge galvanized steel and power coated. The design does not allow animals to enter and easily opens completely when the dryer is in use. Excellent product, easy to install.

Best dryer roof vent ever!

by Terry| 4/10/2014 12:00:00 am

Very well designed product that works exactly as advertised. Low restriction but has a great back draft damper and no screen to clog with lint.

The is a well made product; our customer loved it!


by BigDaddy| 8/8/2015 12:00:00 am

As a contractor this is the best on the market for wall vent or roof venting. I give this an A+ rating


by Jim| 11/21/2014 12:00:00 am

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.

Dryer Jack Install

by Ed| 12/19/2014 12:00:00 am

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!

Dryer Jack - Extra Clearance design

by Dave| 11/4/2014 12:00:00 am

This product is a life-saver! The installation only allowed for roof exit due to interior wall dryer placement in a house built in 1917. The unit is well made and easy to install. I chose the extra clearance unit due to a 2-12" roof pitch and fear of snow buildup. I used a 4" swivel unit to connect to the base so I could compensate for the straight pipe connection. The Dryer Jack is well worth the money and in-route communication was excellent. Great company and great product!

Dryer Jack

by chuck Cox| 8/17/2014 12:00:00 am

Found the Dryer Jack Products on line prior to installing a new roof. As a Real Estate Broker I am always looking for a better product for my customers as well as for my personal use. I was not disappointed, an amazing product, powder coated rather than painted and my Roofer was so impressed he is pursuing use for all his jobs.


by Brian| 9/1/2014 12:00:00 am

Very impressed with product so far, my roofer was also impressed, he will recomend it to future customers. The real test will be this winter when we get snow. Thank You for a great product- excellent customer service.

DryerJack DJK486

by John| 8/9/2013 12:00:00 am

I had a new roof installed and the roffing contractor installed the DryerJack DJK486 with no problems. My dryer is now taking less time to dry clothes than before which will pay for this upgrade in a very short period of time. The vent has a very nice appearence and compliments the new roof. I am very pleased with this product and would recommend it in the future.

DryerJack - extra clearance design - 4" collar

by Don| 4/9/2015 12:00:00 am

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!


by Jim| 11/11/2014 12:00:00 am

GREAT vent system. fixed all my dryer vent issues


by Bob| 6/20/2014 12:00:00 am

This vent saved my son a ton of money. He would have had to run too long of a vent pipe had this option not been available. It works perfectly and was easy to install.


by Scott| 3/11/2015 12:00:00 am

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....

DryerJack - Gooseneck design - 4" collar

by Dan Malcom| 11/3/2013 12:00:00 am

In my search for a well built american made dryer vent, for a through the roof application. This vent can't be beat. I was impressed with the way the vent was built very heavy duty, I found the installation to be trouble free on an existing roof, the collar was placed appropriately to allow for this. the only improvment I could recommend is a rolled bead on the vertical sides of the flange to help with weeping water, although I have had no leaks at this point. I would defiantly recommend this vent over what home depot or lowes carries and their isn't much else to be had since I did a pretty good internet search for this type of vent.

Dryerjack extra clearance roof vent

by Tyrone| 7/24/2014 12:00:00 am

Customer service via phone was excellent. It was explained to us there was a backlog in production and to check back. We ordered couple weeks later and got the item in mail in good time. Product installation was straight forward. THIS PRODUCT CUT OUR DRYING TIME IN HALF!!! We searched for a product locally in Canada and nothing came close to the superior quality and design of your product. We got the extra clearance design as we had one of the worst winters ever this year here in S. Ontario. More people up here will definitely buy your product if they hear about it.


by Bob| 7/24/2014 12:00:00 am

This is an excellent product. I replaced a Nutone roof vent with this one and the difference is amazing. I own apartments, and will be replacing the old ones with this one.

If you are going to vent a dryer through a roof, this is the vent for you. The design engineer of this vent has real grasp of the issues with venting a dryer. I did an exhaustive search for dryer roof vents. Most were made of light gauge metal, and poorly constructed. If you are still not sure what to buy, just search YouTube for "roof dryer vents". It convinced me. Be Safe: Glenn Hills (Retired from East Point Fire Dept.GA. 22 years)
