Steel roof help needed

[mc1984ss]

I just finished "overhauling" my old 16x10 shed. I want to put a hidden fastener steel roof on it but have never installed one. I have a couple questions I'm hoping to get answered

Someone told me to use a traditional drip edge and gutter apron with the underlayment, is that true?

I know for a fact that the entire roof is not as square as I would like it to be but it is what it is. Will this be a problem?

Thank you so much in advance I'm sure I will have more questions

You can look at Mueller Metal's website. They have installation guides for all their metal profiles. Your answers should be in there.

I know regular Ag. and r,p,u panel will have more "out of square" adjustability. I've never used hidden fastener type profiles. I would imagine there is a small amout of leeway but not a lot.

With standing seam layout is key. Find the center point of the ridge and create a square line down to the eave. This is a reference point that will tell you if you have a seam on the line or the center of a panel on the line.

No, you are not going to use traditional drip edge. There is a whole system of trim required for this roof. Decide on which supplier you want to use and read and understand how it goes together. There are more pieces but it is not difficult. This system, if your layout is correct, is actually more out of square tolerant than ribbed panels and it doesn’t show very much.
