Is anyone else's dryer duct routed vertically into your attic space?

Mine is and it exits out of a vent on the roof. It clogs way too often and causes our dryer to shut off prematurely. i know it's a safety feature so i can't be too frustrated, but i can't stand going into the attic to disassemble the duct work and use my drill/brush combo.

the laundry room has a common wall to my garage, and i'm wondering if there's any hazard to cutting out a hole for a short duct (about a foot or so) and have the lint fall into a small bin. potential fire hazard maybe? i have no issues emptying a bin on a weekly basis compared to vertical duct work.

This is a frequent topic of discussion. You can use the search feature for more information.

The possible problem with venting to the garage is moisture. But I have seen it done.

Remember, it's pushing moisture out of the vent, so you could have some moisture issues in the garage. Probably not a big deal with the humidity we get in the south, just something to look at when deciding placement.

I ran the dryer duct into my garage, and out the exterior wall near the garage door. The duct is run inside a cabinet underneath the shelves. It's about a 20' run. Dryer works great and I just hook my blower up to the duct every once in a while and blow er out.

In my last house I rerouted the dryer duct through the pantry under some shelves and out the exterior wall. It made a drastic difference in the performance of the dryer.

I recall researching and finding booster blowers that can be installed in the vertical run to help pull the moisture/lint/etc up through the duct. Bigger issue I was having was condensation filling up the flex duct, not lint.

How long is the run of duct work?

I also have dryer ducted routed vertically (and horizontally) in my attic. I would recommend an in-wall lint trap and dryer booster fan (in attic) - I've had (2) different dryers over the past 7 years with no issues with either dryer.

This is what my brother had to do with his except he just built storage shelves to hide the duct in the garage.

Agree with the pump. Mine runs up to the attic and across to a soffit vent. Installed a pump, clothes dry faster, no lint build up.

My parents had one of these in their garage when I was growing up. The drywall on the ceiling started to mold and such because of the moisture. My dad had to get it routed to an outside wall.

My house currently has the vent routed up through the roof. I think it might have been this board that I read about it on but there are booster fans you can put in line to help out. I haven't bought one yet because they are pricey.

I use one of the drill mounted chimney sweeps from the wall up once per year.

Read the specs on your dryer. It should tell you how far your vent pipe can run without issues. Not every dryer is the same.

My daughter just bought a house that has it vented to the garage. Come to think of it, the paint is peeling in places, which indicates excessive moisture.

I get on my roof, pop the cap and push it straight down. Also get a blower and blow air down through it. Just be ready for it downstairs.

Get a ventless dryer. Got one 5 years ago from Lowe’s. At that time, no one carried them in the store but they can order them.

We went with a whirlpool. It has two lint collectors which we have to empty everytime to every other time, depending on what’s being dried. It’s barely an inconvenience and much better than dealing with cleaning a vertical dryer vent.

ETA: some come with a moisture collector which can be then be used for a steamer cycle, this is awesome if you hate ironing, and others have a water line that goes in the same pipe as the washer drain.

Mine is the same. I run a boost fan on a CT to turn it on.

Mine goes straight out the back wall.

I’ve also been using the whirlpool ventless dryer for about 2years. Had the same issues as the OP. No complaints on the ventless dryer so far. It was more expensive $1600 if I recall, but worth it not having to clean he vent pipe in the attic.

Suck it up, buttercup.

So you'll just blow lint all over the inside of your garage. Those little water trap things don't work worth a shite either.

Do the right thing and get a duct booster fan. Properly installed it will provide the boost in air flow to keep the moisture from the clothes drying from condensing in the ducts and causing lint to stick. They are designed only to operate when they sense the dryer is on. Tjernlund or Fantech.

I did this (rerouted from roof to garage.) There is a moisture issue but if i remember to open the garage door when running the dryer it isn’t as bad. If i leave it closed, it steams up the garage. There is also lint that needs to be swept frequently, but my vent went through 2 stories to the roof and was clogged all the time.

And put a lint trap in the wall as a second safeguard. I have a Fantech booster fan in my attic and have had zero issues with it in 7+ years.

+1. I'm on an interior wall as well. Put a Fantech secondary lint catch in the wall and a Fantech booster unit in the attic. Used to have to run clothes 2-3 times and now they come out bone dry on one run. I have a Speed Queen nat gas dryer.

EDIT: I have since fixed the drywall and put metal strapping under the vent duct instead of nylon.
