Those rollers are toast!
How long have you had your Kettle Pizza?
Lol. I know. Weber sent me a few things under warranty recently including a new lid slider kit incl. rollers due to the melting, a new 22" Mastertouch lid/handle/thermometer combo to replace the performers original lid that was starting to rust at the handle weld. They also sent me a new one touch cleaning kit and charcoal grate. Great company and awesome support! Why I keep buying more webers.
Had the kettle pizza a couple years. In truth, only used it a few times. A pizza night is quite a bit of work so you need to be doing multiple pies to make it worth the effort. Gotta make sure to preheat for some time to get everything got enough. I picked up a big green egg pizza stone and that's been great. The couple thinner ones if tried cracked where the bge has been unstoppable.
Check out the heat in there! Get it hot with a mix of lump and bricks then add a small log of hardwood to get the heat. Next time I do pizzas I'm gonna try wrapping a second grill in tinfoil and putting in the top section of the kettle pizza. I've read this really helps in deflecting heat back down on to the cheese top and speeds up the process.
