Cod 4 or 5, Google it should lead you to manufacturers recommendations, allow 150mm upstand from top of conservatory - if you are in high exposure area include cavity tray.

300 mm code 4 .. 150mm up and 140on the roof . 10mm in the joint .

code 4 is more then good enough. width of flashing depends on where your nearest bed joint IS,
