Cold makes the lint stick

Your dryer pushes warm, damp air out through the vent. Once that air hits the cold part of the run, in the attic or along an outside wall, it cools fast. The moisture in it condenses on the vent walls, and lint sticks to the wet metal instead of blowing outside. On a night near 14 degrees, that happens fast.

Layer by layer, that damp lint narrows the vent. Air backs up, the dryer runs hotter and longer to do the same job, and the exhaust that should leave the house doesn't.

How often should a dryer vent be cleaned?
Once a year for most households. Lint builds up along the whole length of the vent, not just in the trap, and a full year of drying puts a lot of it through there. Waiting longer than that lets lint pack into the bends, where it is harder to clear.
Can I clean my dryer vent myself?
You can clean the lint trap and the first few feet behind the dryer yourself, but the rest of the run is harder to reach and easy to damage with the wrong tool. Vent runs often go through walls or up through a roof, with bends where lint collects out of sight. A contractor uses a brush and vacuum sized for the full length of the duct, which reaches what you cannot.
What are the signs of a clogged dryer vent?
Clothes that take more than one cycle to dry, a dryer that runs hot to the touch on the outside, and a burning smell are the main ones. You might also notice little to no airflow at the exterior vent hood when the dryer is running, or lint collecting around the vent opening outside. Any of these on their own is worth a look, since a blocked vent makes the dryer work harder and can be a fire risk.
