The Cape Cod house doesn't actually a have roof leaks, because the top floor is sort of an attic if Sims sleep up there they will get cold etc. In TS2 Seasons Sims can die from freezing. So, if a child sleeps in the upper rooms they can get cold and possibly get a call from social worker. But if they go back downstairs they are warm in a few mintues. You just have to keep an eye on Sims those roofs don't actually leak etc. I love that house. And the big farm house (red) has an attic like that, too. Or you can put a fireplace up there and have them warm self. Make sure to add a smoke alarm since TS2 Sims start fires and can die.
