Revit family array doesn't change with widht

[pavveETQQ3]

I have made this shed that follows lenght and widht without any issues to the components.

I am suposed to have metal sheets on the roof with a distance of 600mm. I know how to create an array and the formula for it but my problem is that the sheet i create in an array dosn't follow the roof and angle when changing.

The single sheet I create for use with the array does.

I have attached a metal sheet (white) on the roof in the file I attached. Can someone please look at it and tell me what I am doing wrong?

Why are you modeling this building as a Loadable Family?  Why not model it in a Project with Walls, Roofs etc.?  You can easily group the BIM construct together in the Project (Group) and/or load the BIM construct in other Projects (Load as Group).

I'm kind of new to BIM and Revit. AutoCAD is my bread and butter.

My boss wanted this shed (and soon other things) to be as easy as possible for the costumers to just one-click and get everything they want in a single file. To be honest, I'm surprised I got this far in making it as I just started to scratch the surface by trial and error and watching the Balkan Architect on YouTube.

In general an element that needs to array "behaves" when it is created as a nested family. You define the size parameters and create an array of two elements in one family. Then nest that family into a parent that drives the nested family's parameters. Revit tends to control the size parameters in all directions more reliably this way.
