What do you contractors think about all these screwed on metal roofs? Do you think they are gonna hold up?

The key is that we are asking the current "roofs" of all kinds to perform with all of the added insulation and decking and such that tear it up. That goes for metal and shingles and built up. It doesn't work.

Yes Vaa, most thinking, non-marketing roofers here also do not believe that the modern product compares to what is up there and has lasted multiple generations.
If I go east and south into Indiana where the folks don't have as much money as the urban areas, old residential metal roofs are much more common (even a few slates). However, many have been coated, tarred, recoated, sealed, re-sealed and re-coated again.....
I am guessing that some of these I see are pre-WW2.
There are definitely old rusted non-maintained "Lifetime" metal roofs on old barns and buildings around my area. Maybe 60 yrs. old. ?
If these roofs were on a nice home, they'd a been replaced 40 yrs. ago...... :laugh:
(Of course thinking, non marketing roofers know that "lifetime" shingles are a joke too....)

In our area we refer to the ag panels as "chicken coop roofing".I personally would not have one installed on my home,it's a given they will leak and I think they make a home look cheap.I've seen contractors installing them over shingle roofs that have rotted decking,real nice.If you really want a metal roof,get out your checkbook and get a 26 or even better 24 gauge true standing seam metal roof.

It takes a year for the wood to darken around the screws. After that, the amount that shows as actual water varies. It'll last until it leaks. You might even be safe holding your breath waiting for it to happen. :)

Those are the "AG" panels that are being discussed here. As in "agricultural", or pole buildings. will they hold up? Sure! How long? Till they leak. Lay them over a solid substrate like a shingle roof and watch them expand and contract until they are nothing but holes. Oh, I forgot, just put a lot of Ice and Water beneath them.
