You can see in your overlap report that there are a few areas that didn't get nearly the amount of overlap that is required to properly render those areas.
Roofs are always harder to deal with because of the repeating patterns and lower overlap achieved due to it being higher.
Using the Ground Offset feature will make it so taller objects, like roofs, will get the overlap you want it to get.
