As soon as I saw the dryer vent hood I thought it was clogged.
It isn't the proper exhaust hood for a dryer vent that discharges through the roof.
That vent is made for a bathroom or kitchen.
Aside from being the wrong kind of dryer vent hood, it is perched way up on the roof (that picture is taken with a long photo lens), hard to see and get to, and hard to keep clean.
And I could see a little lint popping out here and there.
When I showed it to my older, widowed client, she caught on immediately. "How am I going to clean that?"
I said, "You aren't. You will have to hire somebody. But we will look inside to see how clogged it is now."
And we weren't disappointed.
I was very clogged. The lint is being blown toward the right side onto the roof sheathing and rafter. And there is moisture staining elsewhere.
How else can you tell there was a clog?
During the dryer operation the heat can clearly be seen passing from the right side of the cover, right where the lint is in the photo above.
The dryer had only been on about 5 minutes, and yet the heat generated a long way from it was already at 100F. As that clog becomes more pronounced, and I expect it was very clogged at this point, the dryer can overheat, and literally burn. Yep, a very high percentage cause of house fires is from dryers overheating.
I have this kind of post often because it is crucially important to keep that location clean!
My recommendation: sometimes you don't have to see something to believe it. But a thermal camera can demonstrate some things in ways that photos cannot. While it was apparent from the photograph that the dryer vent was clogged, the thermal image demonstrates it! I asked my client to send me a video of her climbing up there to pop off that cover and clean that baby out! She said she would.
