Not too hard to remove replace but pencil mark all pieces as you go so they go back in the same/exact place.
Draw a plan where all pieces go.
May have to drill some 1/8" riverts out and best to replace the screws when you refit everything.
Silicone to remove scrape off.
In order
downpipe off
gutter off
gutter flashing off
side flashings off
remove screws in receiver channel and beam ONE PANEL at a time to remove each panel leaving all other panels screwed until ready to remove
otherwise they may all come crashing down
panels off using old towels over beam so as to not scratch underside of panels
remove/repair fascia.
Any lights you will need sparky.
