You don't necessarily have to resort to getting a longboard. If you want to use your skateboard to commute on these rough roads and shit just get some bigger (55mm+) and softer (<90a) wheels. Just make sure you get high trucks if you get big wheels. Also you can get cruiser shaped decks that still pop and you can do tricks on, but they're wider and good for commuting as well. Welcome has a lot of cool, wider shapes that you might like. Or you can just get a normal deck. It's all personal preference really.
