You will face Jed after you give Katey the Zombrex shot. This will take place anywhere from 7:00 PM to 8:00 PM depending on when you give her the medicine. Preparing for this fight wouldn't be a bad idea. If you decide to go for some combo weapons, pick ones that are melee based and the helmet/beer combo for health. Though if you decide you don't want to waste time, a broadsword works very well too. The door to the roof is locked once you meet him, which is good because the sniper does almost no damage to him anyways and he will shoot you too. The snack area is open though. Just go back and forth refilling your life and attacking him. He will not follow you back inside.
I found the best way to kill him is to use the sniper on the roof of the safe house and go back and forth from cover using the car you are next to when the fight begins. You can dodge his shotgun if timed correctly and can kill him with about 15 of the 20 shots.
