With AZ Dryer Pros, cleaning a dryer vent that exits through the roof or a second-floor wall starts at $199 in Arizona. The technician checks the airflow, looks at the roof cap, and gives you the exact price before any work starts. If the cap is broken or full of nest material, that is priced separately and only done if you approve it. If you say no to anything extra, you only pay for the cleaning you approved.
Why is my dryer vent on the roof?
When the laundry room has no outside wall, or sits upstairs in the middle of the house, the builder has to send the vent somewhere. In many Arizona two-story stucco homes, that means straight up through the attic and out a cap on the roof. It works, but the dryer has to push lint up a long vertical run, and lint that doesn't make it falls back down and builds up at the bottom and in the elbows.
Signs a roof vent needs cleaning
- Loads that used to take one cycle now take two
- The top of the dryer or the laundry room gets hot
- A clogged-vent or airflow warning on a newer dryer
- Lint or a dust plume around the roof cap
- The roof cap flap doesn't move when the dryer runs
- It has been more than a year since the last cleaning
How we clean it
We start at the dryer: pull it out, take off the transition hose and read the airflow. Then we go up to the roof and clear the cap, which on Arizona homes is often packed with dust from monsoon storms and sometimes with nest material. The run is brushed and vacuumed from both ends so nothing is pushed into an elbow and left there. Then the dryer runs again and we re-measure.
Tile, flat and shingle roofs
We walk tile roofs carefully and step only where tiles are supported, because concrete and clay tile can crack underfoot. Flat roofs with parapets are usually the easiest to work on. If we see a cracked tile, a lifted cap or flashing that looks wrong, we take a photo and tell you. We don't do roof repairs, so anything beyond the dryer vent cap is a job for a roofer.
What changes the price
$199 is the starting price for a roof or second-floor vent. It goes up when the run is very long, badly packed, or needs a new cap. You see photos and the exact price before any of that work happens.
How a visit works
- Book a window. Pick 8–11, 11–2 or 2–5, Sunday to Friday, and tell us the vent goes through the roof.
- Check from inside. We read the airflow at the dryer and look at the hose.
- Clean from the roof. The cap is cleared and the run is brushed from both ends.
- Re-test. The dryer runs again, the airflow is re-measured, and you get photos.
