Welcome, can you upload your pictures to the site, the resolution via the link is very poor.
From what I can see in the poor images I don’t believe there would be significant problem using a pitched roof on option 1 as it appears to just be extending the current shape.
What would help is details of the existing construction, eg truss or stick built roof, and some pictures of the current structure looking at where you are looking at extending. If unsure of the roof construction get a few pictures from inside.
