Match both the diameter and the pitch rating to the job; a jack rated for a steeper pitch will not seal correctly on a flatter roof and vice versa. On low-slope areas, verify the pitch variant is suitable before ordering. Integrate the top edge into the shingle courses so water sheds over, not under, the flange.

Work safely on pitched roofs with fall protection, and follow pipe and penetration clearance requirements for any vented appliance.
