It’s always my first move once I find the sledge if I’m starting in Rosewood, it gives so much freedom. Once you build a door to the roof you can build a covered lounge and dirt plots, that way you can read outside while you watch tv to level skills and avoid boredom all while not even having to consider zeds. You can also toss the generator on the roof outside to cover the whole building. Build a floor before you step onto the roof, though, or you’ll fall through, everything along the wall needs a floor built on it even though there are roof textures there. I live that spot.
