Fully reinforced approach or not

Coatings are problematic for metal panels
Wider panels stretch too far for most coatings.

Fully reinforced approach or notThis 1959 standing seam roof has the narrower width  panels on the right.  Post 1959, a house addition tied in wider standing seam panels, located on the left side of the picture.

So what is the problem?  The dedicated owner to preserving this architectural rarity in southern Virginia coated both style panels in a darker tint.  In under six months, the coating flaked on the wider panels, not on the traditional width.  All the white spots are flakes.

Standing seam panels after 1940s show an expansion/contraction not found in pre-1920s roofs.
Solution:  Fully reinforce (or a version of the fully reinforced) the wider panels, then preserve the standard width panels with extremely flexible primer and coating.
