Some of the pieces for the top roof are not the correct size, cannot assemble.   Looks like I will have to build my own top roof. Have not got any further. Hopefully the rest of the roof has the correct size sections to install.  Also the method used to secure the top roof sections if very poor. I have no confidence in the top roof structures ability to withstand snow load or high winds.   Who ever designed the roof assembly needs to go back to engineering school.
