You're reading into the question, information that just is not there. Don't sweat it though, as while I can't say I see it all the time, I can say I see it often enough to understand it somewhat. For example, under "Describe the residential real estate" you see "E.g. 123 Main Street, Broad & River". The "E.g." signifies that this is an example. Only an example. Nothing more. For description you could put "new thing to cover the walls and floor of the house" and that would actually be fine. In fact, the IRS would know exactly what you were talking about, and probably pass it around to their co-workers for a good laugh.
If you were to install new windows throughout your rental property, that would most likely be a few thousand dollars. That gets classified exactly the same as the new roof. You'd just label it "new windows" is all, and press on.
