I am not sure what you are referring to plus the answer to your question will depend a great deal on the exact style of metal roof being installed. I'd suggest consulting with your metal roof supplier / manufacturer. If you wish, you can also send me details or perhaps photos of the situation at todd@asktoddmiller.com
Have a shed addition to a metal shop. Roof is 20ft panels ,then steps up to 11ft panels. How do i use the rake caps in that corner of the roof
