I’m not that familiar with steel roofs. This valley is in a transition from a steep to a low slope area. It appeared that run-off from the steep slope would over shoot the valley and drive water under the panel on the opposite side of the vally. There was a lot of sealant used in some areas and none in others plus the thru bolts were rusted. Would there be a gasket under the panel at the valley to stop water intrusion?
Sean, look at page 16 and 45 on this link.

Marcel I think it would be easier just to say it is all wrong! LOL
That is basically what I was saying. Just showing details of how it should look.
Wrong big time, no doubt.
What’s the wrongest part part about it?
Not asphalt .
I see bad insulation with Asphalt shingles .
Here I see most steel roofs are very poorly installed .
Steel in Canada costs about 3 times steel .
Most people do not stay in a home long enough to get the reward of the steel life
Steel covered roofs Homes sell for the same price as a steel covered roof ,
so why invest the extra cost when reroofing … Roy
Marcel has pointed out the proper install info you will need to go from the top to the bottom.
Flashing is wrong for Chimney and plumbing stack.
