How to Clean Your Dryer Vent on The Roof

Dryer vents on the roof are much more difficult to clean while not necessarily better or worse. Even though you may be able to clean your dryer vent from the inside, there may be a problem with the roof cover that you can’t see from the inside of the house. If you can’t reach the top of the vent from the inside because of a lint blockage or a bird’s nest, or other obstructions, you may not be able to clean it from the inside. If you are unsure, a professional dryer vent cleaning is recommended.

Clean Your Roof Dryer Vents in 5 Steps!

Here are 5 methods to clean Dryer vents on the outside of your roofs.

Step 1: Unplug the Flex Vent from the power source

To begin cleaning your dryer vent, pull the dryer back and remove the flex vent.

To connect the dryer’s back to the wall, you need to use a flex vent.

It’s also important to clean your flex vent if it’s dirty. Check for flammable lint, debris, holes, and other issues.

Keep an eye on it to ensure it hasn’t gotten squashed beneath the dryer.

A screwdriver is usually required to free the metal clamps on each end. It may also be necessary to remove some aluminum foil tape.

Step 2: Clean the Ventilation System’s Ventilation System

The next step is to use a dryer vent cleaning tool to clean the inside of the wall.

Plastic rods with nylon brush attachments are part of the dryer vent cleaning kit, which includes a series of interconnected plastic rods.

A cordless (or corded) drill is used to attach this device to the dryer duct.

When using the dryer vent cleaning tool, brush the sides of the vent to dislodge the lint. Go up and down multiple times while trying to lift the tool to its highest potential position.

When the dryer vent cleaning tool has reached the ceiling, you’ll hear and feel a thud. The sudden stop’ is caused by the dryer vent cleaner contacting the roof cover.

Disconnection of the Rod Danger

Most home dryer vent cleaning gadgets are made from plastic rods that link to each other. A tool jammed in an air duct can be a real pain to remove if the rods break apart when you’re cleaning it too vigorously.

I recommend sealing the rod connections with duct tape as an additional precaution to reduce this risk.

For the most part, professional dryer vent cleaners use either pressurized air equipment or steel cables to remove lint.

Step 3: Remove Lint from the Vent.

There is an advantage to having a dryer vent that extends to the ceiling because when you clean it from the inside, all the lint falls to the bottom.

According to Duct Cleaning Squads when you remove the dryer vent cleaning tool from the duct, the lint should have gathered at the bottom of the duct. You should be able to reach in and remove several handfuls of lint with your hand.

After removing the lint, I recommend that you keep cleaning and removing lint until there is none left.

It’s time to hook up your blower!

Using a leaf blower to remove any remaining lint from the vent after cleaning it is an option, but I recommend it if you have one.

The lint on the roof cover will be easier to remove with its help (like the flapper).

Step 4: Remove the roof vent from the wall 

This final step is optional, but it’s a good idea if you’re able to reach the dryer vent from the roof. If your roof is sloping or tall, do not risk your life by climbing on it. The best way to get a safe roofer is to look for a professional.

While on the roof, you can clean the roof cover and ensure the flapper is working properly.

On the roof, you can use the dryer vent cleaning equipment to clean the upper portion of the vent. You should be able to remove any lint that you remove from the vent by hand.

Step 5: Verify the Flow of Air

Additionally, I recommend having someone use a leaf blower or a drier while on the roof to ensure appropriate airflow.

You can tell whether the vent is clogged if there is no or minimal airflow.

Look up in the attic to see if there is a duct disconnection to rule this out.


Dryer vent blockages on the roof are not uncommon. Keeping a watch on the dryer’s performance during its cycle is vital, as previously said because forcing air up and out of the vents is difficult.
