The two roof panels are connected by small hinges that seem inadequate for their size and weight, especially considering they're made of MDF. The roof front panel's hinges are hidden on the inside, while the roof back panel's are on the outside. Given the size of the hinges, this design does not give the panels much leeway for movement. This likely means the panel won't sit flush against the side walls when closed, instead remaining slightly raised. As a result, replacing these hinges with larger, more suitable ones may be necessary.
For the sake of demonstration, I will leave them as they are for now because they are not needed until much further along in the assembly and this is how you are instructed to place them.
