I unhooked the dryer vent hose from the wall and used the following dryer vent cleaning kit to get as much of the lint out as possible. Although I was able to get a lot of lint out, my dryer wasn't getting hot afterwards so I unhooked again and blew my leaf blower through it at full speed and that finished the job!! Had quite a bit of lint on my roof but dryer has worked perfectly ever sense and that was about 3 to 4 years ago.

Love how you put a screen shot of a leaf blower just in case someone doesn't know what one looks like.

I did this a few years ago and it was very difficult, until it suddenly became very easy.

The vent line had i think 3 different right angles before it got to the exterior wall, so it was very difficult to get that brush to navigate all the turns and still have any ability to push through the rest of the pipe. It would only go so far before it just wouldn't move any further no matter what i tried.

So, i tried the leaf blower trick and it wouldn't work. You could feel very little air flow at the outside vent even with the leaf blower at full blast. Kept at it for a good hour back and forth between the brush and the leaf blower before my fianc (now wife) suggested i try using the leaf blower from the outside and blowing into the house.

I had her standing in the laundry room to see if any air flow was coming through the line. Turn on the leaf blower and about 5 seconds later i hear her screaming! I run inside and see her absolutely covered in lint with a huge cloud of it floating around. Turns out the vent line had a reduction in it somewhere so there was a shoulder that was clogged, preventing the lint from blowing out. But it was able to blow in just fine!

After being relieved she wasn't hurt and didn't try to kill me, we closed the door to the laundry room and i got on the leaf blower again to make sure the line was clear. Made a huge mess in the laundry room but it worked! Then tried blowing from the inside out again and got plenty of air flow all the way through the pipe.

We all have tests to make sure they're worth keeping long term

Good tip for the blower in the vent line (I suppose either way) is to tape a pair of panty hose onto the roof vent so it catches all the lent.

The first time I did it, I had lent everywhere and it stuck pretty decently to the shingles so it was a paint to get it all off.

You also want to be careful with the blower method, the PVC or metal duct through your walls and attic may only be friction fit and could blow apart if you have a clog.
