I believe they will be installing a Z Channel between the ribs, and sealing it into place. The ridge / shed cap will then lock over the Z Channels. Because of the short panels, they will have to have a pretty large ridge / shed cap. If the Z Channels are sealed in well, though, the short panels should not pose a problem through the cap will not be well supported in those areas.
I'm wondering if this is normal and okay. the panels are between 4 and 8 inches short of the top edge of the roof. The roofer says it's fine.
It seems to me that this is just a potential leak zone and that even placing a second piece over the top to extend to the top edge before a flashing is installed is not a correct installation.
I'd love you opinion.
