How to Vent a Stove Through the Roof
Ask Danny, Attics and Basements, Kitchens and Baths by Danny Lipford
I have a range that is located against an outside brick wall in a one-story kitchen with a flat roof. To avoid going through the brick wall, can I vent the hood straight up through roof? What sort of cap would I use that would prevent insects from entering but would still operate properly in a strong wind or with a heavy snow load? Thanks! John
Hi John,
Yes, you can vent a range hood through the roof using a 6” single wall pipe. You can buy the proper flashing to install it on a flat roof and a roof cap that has screen around it to prevent insects from entering. Be sure to extend the pipe up at least 2’ to 3’ to prevent snow buildup from causing problems.

When roof venting with over the range hoods, if you use high CFM’s are they noisy? The higher the CFM’s , the higher the noise? I saw a comment somewhere also that not all CFM usage is the same. IE: say using 600 CFM in one instance may not be the same as using 600 CFM in another instance. We will be rising above the hood vent apprx. 15 ‘…how do we calculate how much CFM is needed?
