Sorry for the delay. Your post got stuck in moderation due to its referencing a different service. Please read the data collection guidelines that you agree to carefully. They specifically say not to include orbit imagery. Also roofs are surprisingly hard to process well when they are reflective metal like you are dealing with. if you are looking to render the vertical surfaces on the side of the building, you should be using the ‘Full 3D’ option in Step 2 of the uploader. Otherwise you are just going to be getting a 2.5 D model that does not render the verticals.
