Am I wrong in thinking this will be a nightmare to keep clean?

I’ve always heard to never vent through the roof. That type is easily clogged and can cause the dryer to catch on fire.

Bought the house like this. I have to clean it pretty often like a chimney swift pauper or some shite. It's going to eventually be rerouted but that remodel is a few years away. I can't do it now without crossing a doorway

I don’t think so. There’s no way for lint to escape. I use a gooseneck vent on dryer vent roof penetrations and have to remove the metal grate that comes on it.

How do you clean it? Mine vents through the roof, and every now and then I run a cleaning brush through the pipe from both ends.

Basically a 40 year old version of this, with a removable cap.

I have a dryer vent cleaning kit similar to pictured that attaches to a drill. I set a reminder and every 4 months or so I clean it. When I bought the house it would take 3 or 4 cycles to dry because of how constricted it was.

That's what I was thinking, just wanted to see if I was overthinking it.

I guess I meant, can you pop that cover off somehow?

Whoops, my bad.

No, you can't. The one I had previously had some dampers that would open when the dryer came on. I'd have to clean it pretty often which is why I'm concerned.

It's a shitty design to have it vent to the roof but unfortunately I'm stuck with it for now.

I had a house with a roof vent, that one will not work, it will clog.

Call a local roofing supply yard and see if they stock the Dryer Jack brand. This model is DJK-466. Free flow design with a baffle. Zero backpressure and no screen to clog. Should run about $50.

Thanks,
I'll mention that one when talking to the roofer. I haven't paid him yet and won't until he swaps what he put there out.

Just ordered this, the house we bought has a roof vent, but I suppose the previous owners didn't want to use it so they installed a wall vent that vents into the garage, which we don't want to use because it makes the garage hot and humid and a mess with lint. We're using the roof vent but I doubt it's ever been cleaned.

Per 1502.3 exhaust duct terminations shall be equipped with a backdraft damper and screens shall not be installed at the duct termination.

no, that thing will clog up every few days

it has to be an open, unrestricted vent, with no screens, so the dust can fly out.

something like the one in this link LINK

for now until you can get it changed out, just get a dremel or some snips and cut those screens out of it so the dust can get out and not clog it.

also, what you have there is not up to code, and is an actual fire hazard that could burn your house down in some cases. maybe thats something you can address with your purchase agreement if you just bought the place since it is a code violation and a safety hazard

I had something similar on a new construction home and within two months, it was clogged. Clothes weren't drying and when I popped the hose off behind the dryer, water came dripping out. The builder came back and put the dryer jack previously recommended and have not had any issues going on almost three years.

Then you gotta worry about the lint clogging your gutters if you don't have guards. Hopefully it's on the back of the house.

I'd have to get rid of the roof vent and put it through a wall.
