Dryer vents play an important role in drying your clothes quickly, while also making sure your home is not at risk of fire hazards. This is why cleaning dryer vents regularly is so important. But, sometimes people have their dryers on the upper floors of their homes, and the dryer vents go to the roof, instead of the outer walls.

This makes cleaning them quite difficult. 

This is where knowing how to clean dryer vent on roof comes into play. Cleaning dryer vents that are on the roof involves more or less the same steps as cleaning regular dryer vents. You have to shut the dryer’s power off and remove the flex vent from the inside and clean it. You also have to go to the roof and clean the vent from the outside. 

Let’s take a detailed look at the steps for cleaning dryer vents on your roof.

Dryer vent cleaning is a relatively simpler job than cleaning other vents and ducts of your house. But sometimes the task becomes a bit more challenging since a lot of people are now having their dryers on the second and third floors of their homes.

As a result, the dryer vents are opening to the roof, instead of the outer walls. 

Since the roofs can sometimes be quite steep, we suggest you hire a professional dryer vent cleaning service to clean your vents. This is because they have the necessary skills, experience, and tools to safely and properly clean your vents without causing any damage. 

Here are the steps for cleaning dryer vents on the roof:

1. Turning the power off

Turn Power off

Before doing anything with the dryer and the dryer vent, you must first ensure that the dryer isn’t connected to any power source. Turn the power off before starting the dryer vent cleaning procedure.

If you have an electric dryer, disconnect it from the electric outlet, and for the gas-powered ones, turn the gas supply off. Then pull the dryer to one side. 

2. Removing the flex vent

Removing the flex vent

Flex vents are small ducts that connect the dryer to the vent in the wall. Remove them by unscrewing the metal clamps.

If the flex vent has any lint, then clean it using your hand, or a brush. 

3. Cleaning the vent from the inside

Once the flex vent is removed and cleaned, you will now have clear access to the dryer vent inside your wall. First, clean the edges of the vent with either a brush or your hand. Then, use an extension kit, which is a brush connected to a series of interconnecting rods.

Use this kit to clean until you reach the top of the vent, that’s when you will hear a thud. 

There are a couple of things you have to keep in mind when you clean your wall vent. First, you have to repeat the cleaning process a few times to get rid of all the lint from the vent. Also, the interconnecting rods of the kit can sometimes get disconnected and fall off.

To prevent that, you should tape the rods at their joints. 

4. Vacuuming the vent

Once you are done cleaning the wall vent with the cleaning kit, you should vacuum the vent so that you can get rid of any residual lint or other debris from it. There is another alternative to this.

Instead of sucking the lint in, you can use a leaf blower to blow everything to the vent opening on the roof. But we suggest you use a vacuum cleaner. 

5. Locating the vent opening

This is where you will need the help of our dryer vent cleaning service the most. You need to locate where the dryer vent opens on your roof. For this, you will need the professional/s to go on the roof and locate it. 

6. Cleaning the vent

Now it is time to clean the dryer vent on the roof. The dryer vents that are on the roof, are usually sealed with caulk to keep them in their place and to ensure water and debris can’t get into them. The professionals have to remove the caulk and get into the vent.

Then they will use the cleaning kit to clean the vent like before. This will make all the lint and debris fall inside the dryer room. Once the vent is cleaned from the outside, you should use a leaf blower from the inside to see if the air is properly flowing again.

Once you are satisfied with the airflow, the professionals have to put the vent back into its place and seal the area again with caulk. 

7. Finishing up
