Above the Roof
What Do I Do

The chimney must extend at least 3' above the highest point where it passes through the roof surface and at least 2' higher than any part of the building within a horizontal distance to 10'. * Note: When calculating the installed length of your chimney subtract 1" for each joint and include the Height Requirements shown in this illustration.
