It’s entirely normal for dryer vents to get clogged up after some time. However, you’ll want to troubleshoot further if it keeps getting clogged more often than usual. A dryer vent that clogs quickly is a sign that the appliance is being used more often than usual. Households with large families, for instance, use their dryers more frequently. Bulky items and new clothes also contribute to the problem by creating lots more lint than regular laundry. Lastly, a dryer vent line with lots of bends and turns will also clog with lint much quicker than usual. In this article, we’re going to explore the reasons why your dryer vent keeps getting clogged. We’ll also pay special attention to why this happens with dryer vents that terminate at the roof instead of a sidewall. How Often Do You Need To Clean A Dryer Vent?On average, you should inspect and clean your dryer vents at least once a year. The best way to perform those tasks is to disconnect the vent entirely from the back of the dryer and at its termination point (i.e. the part that leads outside through the vent cover). Cleaning your dryer vents once a year will prevent any significant buildup of lint and dust in the vent and help your dryer to function at its best. Reasons You Need To Clean Your Dryer Vent More OftenSuppose your dryer vents keep getting clogged more often than usual. If that’s the case, then you’ll likely need to clean the vent more often for one or more of the following reasons:
What Happens When A Dryer Vent Is Blocked?When a dryer vent gets clogged, you’ll experience the following side effects:
When airflow through the dryer vent is restricted, the moist air from inside the appliance cannot escape efficiently. That will result in your clothes staying wet for much longer.
Why Is My Dryer Still Showing Signs of a Clog Even After Cleaning The Vent?Suppose you’ve cleaned your dryer vent thoroughly, yet you still see signs that the vent is clogged (e.g. clothes taking too long to dry and the dryer is overheating). If you’re sure that the vent is clear, then it’s time to consider that the blockage isn’t in the dryer vent. Remember: the air has to travel through several dryer sections before it even reaches the vent. So, there might be a clog inside the dryer itself. Here’s how you can troubleshoot the problem of an internal lint clog within the dryer itself:
What’s Causing My Dryer Vent To Keep Getting Clogged On The Roof?Some homeowners have dryer vents that exhaust out through the roof. If your appliance is designed to vent this way and keeps getting clogged, then there are some slight differences that you need to be aware of. Here are the troubleshooting steps you’ll need to follow in clearing that clog. Longer VentsWhen a dryer is vented out through the nearest wall, the hot air and lint don’t have to travel very far to exit the building. However, the dryer vent will stretch much further if you’re venting it out through the roof, as it’ll have to travel to the ceiling and through the attic (if you have one). What difference does that make? Well, when you have a long dryer vent line, the hot and moist air can get stuck inside the duct. That means the lint and dirt will also have a much more challenging time exiting the building through the vent at the roof. As a result, the dryer vents could clog at the roof simply because there isn’t enough airflow to push all the air and lint out through the vent cover. Kinked or Crushed Dryer VentIdeally, most of your dryer vent line should consist of rigid parts that don’t bend or get crushed easily. Still, some parts will have to be flexible to make it easier to connect to the appliance and the vent cover. Those flexible vent sections are at risk of being kinked, thereby restricting the airflow passing through them. That tends to happen when homeowners use flexible ducting to snake around the attic on its way to the vent cover. Related: Dryer Vent Repair – Should You Fix It By Yourself? Besides that, dryer vents can also get crushed by boxes or other items that have fallen onto them. That’s especially true with flexible vents, which cannot resist much weight at all. Vent Exhaust ProblemsLast but not least, the problem of a clogged dryer vent at the roof could be at the vent’s termination point, i.e. the vent cover or exhaust on the roof. These covers come in many shapes (e.g. angled, box, or louvred). No matter the shape, one thing they have in common is that they each have a hinged flapper door. That door keeps the vent closed when it’s not in use. If, however, that flapper door is stuck shut, then your dryer will not be able to vent all the hot air, moisture, and lint from the appliance. With nowhere to go, the dryer vent is likely to get clogged very quickly. How Do You Clean Your Dryer Vent From The Outside?To clean a dryer vent from the outside, all you’ll need is an extendable brush and your vacuum. Related: How Often To Clean Dryer Vent? It’s best to remove the vent cover entirely, if possible. If not, you’ll want to try and keep the hinged flapper door open so that you can stick an extendable brush inside.
So, once you’re done cleaning the dryer vent from the outside, it’s also an excellent idea to clean the vent where it connects to the dryer inside the house. Why does my dryer vent keep clogging up?Many things can cause your dryer vent to become clogged. Most of the time, it's lint that becomes trapped in the vent. Over time, this accumulates and begins to block the nearby airflow. Other times, nests and other debris can cause a clog.
