Roof (and more) - December 2012
This has been "repaired" twice.
Original lower roof started at eve of mobile home with no flashing, had only a 2" drop in a 12' run with no sealant at seams.
One of the repairs (I guess the first) consisted of changing the pitch to about 3/4:12 and extending lower roof by adding panels. However, the top of extension was left over the upper roof. The end pictured here was the worse end with a gap of about 1" filled with caulk.
The panels were "attached" directly to 3/8" OSB. The wood screws used (they were the correct ones) can easily strip out of this material. Minimum thickness of OSB should be 1/2" for this application to increase "hold-down" strength.
Metal panels should always have an underlayment or dead-air-space to prevent sweat damage. If over shingles, there should be a cushion or furring to prevent etching from gravel.
I recommend using 1/4" fan-fold insulation (shingle cushion) or a synthetic material (underlayment/moisture-barrier plus fan-fold for bare wood) rather than felt (tar) paper.

Second "Repair" seems to have consisted of covering with a tarp.
Oops, I didn't hold the camera level.
Changing the 3 roofs into a single plane.

They were not electricians either
