Who or how to clean dryer vent through roof

Clear it yourself

The dryer takes 3 cycles to dry clothes.

Are you 100% that it's clogged in the wall?

Most of the time the clog is in the vext coming from the dryer to the wall as it's usually flexible and easy to accumilate things.

The answer to your question though is this.




then get some extensions.

Home Depot and lowes carry something like it but Amazon is your best bet.
I have one I use and clean the vents as an upcharge on a repair.


You snake it through and hook it to a drill

So the dryer has to push lint upwards?

---

Ideally you want to catch all the lint, but that doesn't happen. I have seen systems with added lint traps, systems with extra suction fans, and the one I find oddest of all, but it's increasingly more common...

The ventless exhaust.

(which just gets lint everywhere)





Be mindful of dryers and lint.



About once a month I see evidence of a small internal lint fire that just stayed in one spot or never jumped from the inside to the drum.




(rarely as bad as above)


usually more like this





and generally yes, electric dryers do start more fires than gas dryers.

I'd say that there is a better chance that the vent line just came loose from the connection on the wall. This happened to us a few years ago. At least worth a check.

If that happened the clothes would dry great as it would have maximum airflow. The dampness and humidity scream a restriction in the flow.

Can you access where the vent exits to the roof? My vent pipe ran to a roof vent with a screen which clogged often. I ended up removing the screen. I use an electric leaf blower to blow the pipe out but I do have to clean lent around the roof vent by hand too.

Do you guys not have filters in your dryers that catch lint before it gets in the ducts? I for one have never found much lint in the duct, and what blocked my roof vent was damn birds building nests in it. You see, the POS builder didn't use a screen on the roof vent. Believe me, a pound or two of bird nest is very bad for the airflow.

No, definitely just condensation from the long run. As the exhaust travels up, the cool pipe cause the hot air to condense water from the moist air. It drips back down into flex pipe.

I fought if for years. It sucks. Made me hate my house and the dryer.

If you are near an external wall, I'd try to find a way to get there. I routed my through wall, into my pantry, and under the bottom shelf to the outside. Was actually pretty easy to do. Bought some "semi-rigid" duct and the fittings/finishers and knocked it out in a weekend. Drilling through brick was most difficult part.

ETA: Other thing I looked into was a supplementary booster fan and/or insulation. Try to get the velocity higher so it doesn't condense. Also tried to install a drain in my flex hose (cut in half and put in hard duct with drain fitting). Made it a little easier to drain by not having to pull out dryer, but still a huge pain in the arse. Also caused more lint to collect around the drain fitting.

Can you explain how you did this?

Bought a masonry bit, good electric drill, and basically drilled small holes all around the outline of the outer finisher. Then used a hammer/mallet. The brick is pretty brittle so it'll fracture along the small ligaments between the holes.

You hit the nail on the head. That's my problem. I can vent it into my garage, which might be what I need to do. Thanks for the help, and for saving me a few bucks. Owe you one.

When I bought my house the dryer was vented through the roof with flexible dryer hose. I took that shite out and put in a ridged aluminum duct and have had no problems in 10 years. I don't think the previous owner ever cleaned the lint screen in their dryer either.
