This is because the model was created with sketchup and they didn't create a proper model. some of the parts in this (I think those corner diagonal things) have the triangles in the STL showing their normals backwards - the "normals" in the STL say which side of the triangle is solid and which side should be air. So when cura slices it gets confused.
Always look at a part in slice view and if shows that it is printing somewhere it shouldn't - don't think it won't do that when you really try to print. Slice view tells the truth.
So what's the solution?
You have a few options.
1) You could easily fix the sketchup file - right click on the gray walls and select "reverse faces" to make them white. the skp file (the sketchup file) is included so I'd go this route. Because I've used sketchup a lot.
2) You could sent the STL through a cleanup program - this one is free but requires you to create an account:
Nice detailed answer, thank you. I was going to attach my own roof from sheet styrene, so I'm not too worried about the fact it actually printed one for me (incredibly, it spanned that gap). Was just perplexed about the way it was presenting. I think I'll send this link to the original Thingiverse author so he can potentially correct it at the source.
I use Layer View all the time when evaluating a print - it reveals so many issues before actually printing the items.
As the designer I've pleased that others are finding my projects interesting. But more importantly by your sharing your comments I am able to learn so much from others. Great fun. I will correct the wall.stl and repost it.

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

3) There are some model repair options you could try in Cura. "mesh fixes". I thought there was normal fix but I don't see it.
