I apologize if this is the wrong area for this question. I'm installing ventilation for a small glass torch and need flashing to fit over a 12" pipe(stack) on the roof. I just spent 4 hours searching the net and calling every store near me that could possibly have it with no luck.

I would be soooo grateful if someone could point me in the right direction. Is there any place online I could order 12" flashing? Or anyone know of a place near Orange County Cali?

Thank you! Boog
