When your oven is sitting outside under a roof or shelter, you can't simply put the flue straight through the roofing material. The flue gets very hot, so you need a proper penetration system to:
Keep hot flue pipe away from combustible roofing materials
Prevent heat from damaging the roof
Keep rain from leaking through the roof
Provide a neat, sealed finish around the flue
Maintain the correct clearance around the flue
Allow the flue to safely extend above the roof
 
Our Flue Penetration system will help you get through a roof safely.
