DryerJack Installation

The DryerJack 477 is designed specifically for venting the dryer through the roof. For optimal results, install the DryerJack with the versatile RoofNeck collar.

Professional installation is recommended.
Step 1: Start by determining the location to install the roof vent.

Step 2: Using the included template, drill a pilot hole on the “X” to mark the center of the hole location for ductwork.

Step 3: Trace around the perimeter of the template. 

Step 4: From the pilot hole mark, cut a four and one quarter inch circular hole into roof deck for the ductwork. 

Step 5: If installing the RoofNeck collar, begin at Step 3 in those instructions and complete the RoofNeck installation. 

Step 6: Cut the roof covering along the traced line and remove. 

Step 7: Apply roofing sealant along the underside of the flange. 

Step 8: Slide the flange underneath the shingles. 

Step 9: Using the predrilled holes, secure to the roof deck with corrosion resistant nails or screws. 

Step 10: Apply roofing sealant to the underside of the shingles and lay over the flange. 

Step 11: Finish the installation by applying roofing sealant around the base of the hood and exposed fasteners. 

The DryerJack is now ready for use.


Roof Vent Advantages

  • Airflow Efficiency

    Superior airflow efficiency is achieved thanks to the combination of a unique curved damper and larger vent opening.

    Allowing the dryer to perform at peak efficiency helps reduce lint buildup (and the resulting fire hazard), and it keeps dryer times low which can reduce wear and tear and saves energy.

  • Maintenance Access

    Dryer exhaust systems need to be cleaned—from beginning to end—regularly. The DryerJack® includes special design features for ready access that is easy on cleaning tools. The ability to clean vents from both ends can be a major advantage for longer runs, and it is helpful for a thorough cleaning.

  • Protection

    Bird, rodent and rain protection:
    Your natural intuition might insist that a screen exists to shield bird and rodent entry, but the 
    building code clearly prohibits their use in dryer venting as they quickly get contaminated with lint. Special attention to the shape, position and how the damper rests inside the hood when closed, delivers a high degree of intrusion prevention without the use of screens. A seamless hood helps prevent water intrusion in the exhaust duct.

  • Quality Construction

    Tough as nails construction, the 477 is deep drawn right here in the US, and ensures a very long duty life. The tightly engineered housing, flange, damper and collar are all constructed of heavy gauge Galvalume®.

    The DryerJack hood features balance aesthetic objectives with application requirements. Rounded flange corners simplify handling, and built-in nail holes help speed installation.

Performance Matters

Typical roof terminations have been proven to restrict airflow to a dangerous level when it comes to venting dryers. Poorly designed roof vents are more than just an eye sore; they are rarely duct cleaning accessible or pest resistant.

The DryerJack delivers advanced performance for improved safety, efficiency and duty life.

A Better Roof Termination

DryerJacks are the first roof vents designed to meet the more stringent venting requirements of dryer exhaust systems. 

Considering that back pressure higher than .6 WCI is generally recognized as inefficient, you can see that venting through the roof with non-dryer specific vents is immediately problematic. The less back pressure is created by the roof vent, the more efficiently the system performs.

The new DryerJack is the most efficient. The position and curvature of the damper, combined with hood size, optimize airflow to such a degree that laboratory tests confirm only the most marginal reduction in airflow. Terminating the shorter duct run with a DryerJack helps venting through the roof deliver on the promise this shorter route offers.

At less than 5 1/2" above the roof plane, it is also low-profile for minimal visibility. For medium snowfall zones and / or higher profile roof tiles, select the larger model 486 which is as efficient but taller.

Excellent product

Vent was delivered on-time, the quality was outstanding. Installation took less than 30 mins; went flawlessly. - Happy customer

Great seller

Good price and fast, secure shipping. Would buy from them again. - Ryoji

Excellent product

I bought this vent to replace a dryer vent on the roof which wasn’t fit for purpose or compliant with code because it had screens. This Dryerjack vent is well made, reasonably priced, and works great. - Ryoji

Works Reasonably Well

This product was relatively easy to install, and seems to work OK. However, it doesn't open all the way when the dryer is on, even though we have a relatively direct connection from dryer to vent. Because of this I'm guessing we'll have more resistance to the airflow and thus more potential of lint build up in the duct. Also, I wish the optional RoofNeck collar were included with the DryerJack, as it is with a couple other suppliers I have found online since ordering this product. We had to purchase it separately and pay separate shipping. Shipping time and communication was great, and I think the product will suffice for our application, as long as we make sure to regularly clean lint out of the dryer ducts, which should be done anyway with any duct/vent combination. - Joe

Huge improvement

We bought this vent after doing some research on what the best dryer roof vent would be. This product actually has engineering that's gone into it. After installing, our dryer works dramatically better. Very pleased - Jesse

Tough housing for wind.

I installed this version of roof vent after the standard type let snow in my dryer. The wind would blow the old one open and let dirt and snow in the dryer.
This vent is not even close to the standard vents by design and quality. Much better!!!
Tough housing and smooth air flow.

I wish they made a version a little larger for my other vents on the roof. - Anonymous

What a Difference

Great product! Easy install. Reduced the time to dry by 40%. A great product. - Anonymous

D Gates

Excellent product and easy to install, especially when installed with optional collar. You can visually see that the vent damper creates very little back pressure, never-th-less the animal proof metal damper automatically when the air flow stops. -

Roof Vent

I was looking for a well designed roof vent that does not look like all the typical eye sore vents that are normally installed by builders. The roof vents sold in local big box stores are poor quality. The DryerJack vent is well constructed and works great. The clothes are drying much faster and that should translate into lower electric bills. - Mark R.

Exceeded my expectations

I needed to replace my dryer vent and decided to look at different vents available. After researching on-line and YouTube, I landed on videos for DryerJack. Because of their presentation and what they were claiming, I decided to give them a try. Why not, right? Well after ordering the 477 from Animal Traps and Supplies, I received it about a week later and installed it. The hype is 110% true. DryerJack lives up to its name, quality, and purpose. My clothes dry between 30% to 45% faster than they did before. If you want a high-quality product, DryerJack is it and ordering one from Animal Traps and Supplies is the way to go. Ordering was easy and delivery was fast. Extremely happy with everything. - Nik N.

Great product

We had our dryer vent that is located on the roof of our house replaced with the DryerJack. Now we don’t have to worry about anyone scaling our roof to clean our vent. The DryerJack works perfectly! - Sonja

Best roof vent dryer option

Installed easily and the heavy gage metal is built to last. Just Installed it though. Time should confirm that. - Wade Gauthier

The Perfect Dryer Roof Vent

We recently remodeled a 1939 Cottage moving the washer and dryer out of the kitchen and into a hall closet. This required the dryer vent hose be routed vertically through the ceiling and then out the roof. I researched a lot of different roof jack brands and decided to purchase the Dryerjack Vent 477. My biggest concern venting the dryer hose vertically was developing an accumulation of lint in the hose over time creating a fire hazard so I mounted a booster blower fan in the attic and found the Dryerjack Vent 477. It was the only roof jack that created zero back pressure, had a flap that automatically closes when the dryer turns off rather than a lint trapping wire screen, was easy to install plus the low profile design looks great on the roof. I was blown away when someone from the company called me within an hour of placing my order to let me know the color I chose was on back order and offered me the option of picking another color or waiting a week or so for the color I ordered. I stayed with the original color and was surprised a second time when the company called me again to give me an update on the expected deliver date. I definitely recommend this company and this product. The exceptional customer service and reasonable price was very unexpected but greatly appreciated. - James

Solved Florida dryer problem

We bought a house in Sun City Center Florida which had an old style dryer vent through the roof. It was prone to clogging and about every other month I would have to climb up and clean the lint out because the dryer wouldn’t dry.

After installing this roof dryer vent, clothes dry even on the low heat setting which it never did before even after cleaning the old vent. Excellent air flow with quality materials! - Anonymous

Dryer Jack Roof Mounted Dryer Vent 477

I am a roofing contractor and this is the first time I have used this vent. It is made of heavy gauge metal with a high quality paint finish. There us nothing on the market that I have seen that even comes close as far as the quality and the price is comparable to the inferior units you see at Home Depot Bd Lowe’s.

Animal Trap and Supplies did a great job getting the product to me in a timely fashion at a competitive price. Great folks to do business with. - Anonymous

Looks great and after opening and checking it I believe it will work as advertised but haven’t installed yet so not able to say how it works. - Jerry

Dryer vent replacement

Installation was easy as I was replacing a standard attic vent that was installed by a roofer as a dryer vent and was near impossible to clear of lint. You just need to use a roofer tool to get under/raise the existing shingles being careful to pull out the nails. I had to line up the dryer vent with the hole in the roof, making sure it was under the shingles on the sides, nail it in place, cut and insert 2 shingles above the dryer vent, nail them in place and caulk everything. - Don
