Ok that is weird, I never heard of that. Did you try to test the houses? That info could be out of date if it was patched. I have used that same roof type on a ton of my builds and never had a issue with it.. I couldn't find any info on this except for the wiki. I did find some makeovers of the lots in question, but they are makeovers, so it doesn't look the same. You can take a peek at those here

I imagine you could remove the roofs, and select the same style of roof and auto roof the house. That should take care of the issue.
