So any guesses what caused this

[Wayne B. Wilson]

This is from today's inspection . Any guess what cause this . Just curouis i know what it is , I truely believe thermal cams are the way to go.

Hard to say without more info. but my guess is

A. Water intrusion from the 2nd story roof, or
B. Depending on the delta T, it could air infiltration/ex filtration due to the improper installation of the siding/soffits and roof framing of the farmers porch

More info needed

It's heated up with the siding expanded out there. Is it a heat duct/boot leak?

[Wayne B. Wilson]

temp was 116 at the center ,outside temp was 70 cloudy.
No roof leak, no problems with flashing
Not a problem with furnace venting.
not a problem with water

[Peter C. Russell]

Lack of nailing in the vinyl siding is causing an air pocket to heat up under the siding.

I noticed a large buckle under the siding to the right of the porch roof.

Wayne,

Nothing surprises me anymore...

I've seen bulge in drywall due to a forgotten receptacle but this is a first for me!

Clothes must have taken a long time to dry…

[Wayne B. Wilson]

What worries me , is how many others are like that in subdivision, i seen one next door for sure, hopefully no fires will start.

Talk to the local fire marshall and let him know what you found? Ya know, on the lines of doing your civic duty for the safety of the residents. Shouldn't take them long to canvas the subdivision looking for non-existant dryer vent outlets.

Heck, you never know. If discovered to be a widespread problem, you may get some free publicity in the newspaper and the local news station.
