A good repair kit is necessary. I used to commute by bike regularly and flat tires would happen from time to time. There's a lot of sharp debris out there on the roadways. Not a terrible thing to deal with if you have tools and a patch kit. Things loosen up over time as well. I keep a spare tube, a patch kit and some tools in a bag under the seat. You'll want a good lightweight pump as well.
