I put on a roof just to have something to land on, which becomes a challenge itself since I am on a hill and it takes a while to recover from a missed landing for another attempt. I think I am the only person within 5km who has a roof, other than the market.
When it comes time for you to try to leave "this damned-dirty sanctuary moon", a few words of advice. If you think you have enough lift/thrust to get you to space engine ignition, your probably don't have enough. If you KNOW you have enough engine to get there, you might. That last few hundred meters is a real mother to cross.
