Hello, and thank you for your contributions to OpenStreetMap. It looks like you have directly traced the roof outline from overhead photos, but the roof angles have added extra corners that don't exist in the building outline. The building outlines should be more "rectangular" to match the blueprint of the building. Please see the guidance here with respect to "double pitched roof": https://wiki.openstreetmap.org/wiki/Roof_modelling#Typical_errors_in_the_interpretation_of_roof_geometry_from_aerial_images
Also, the iD editor can help automatically make objects more rectangular by pressing the Q button while editing an object.
