How to roof an architectural roll in the roof with composite shingles

I am having my house roofed. The home designer put a very unique feature in front of the house. I call it a flat top roll that diminishes as it goes up the roof.How can this be roofed to look great with a composite shingle (GAF Camelot) ?? I have tried to upload pictures from a Canon Powershot but am getting a server error from the website??

Have you tried downsizing the photo? Are you trying to upload it below where you type in the post?
