Images of chimney hieght above the roof.

The chimney must extend at least 3 above the highest point where it passes through a roof. What is the 2 foot 10 foot 3 foot rule. Positing a chimney on the home relative to the rest of the home may cause it to draw better. Easy calculation for chimney pipe height.

For larger structures the result will depend on the roof pitch. The top of a chimney pipe must extend at least 2 feet above the peak of the roof if the pipe is within 10 feet of the peak. If the pipe is farther than 10 feet from the roof. This doesn t necessarily mean the pipe must be above the tallest part of the roof which is known as the ridge.

But the pipe will require a 10 horizontal clearance from the roof. Per the 10 and 2 rule once you are at the level of the peak you only need to be 2 feet above it. If your peak to penetration distance is 7 feet you would have a rise of 28 inches. Knowing the pitch of the roof is extremely helpful in determining the height the chimney pipe must be above the roof.

This is a bit of an odd measurement and chimney clearance case because the chimney side is actually about 8 away from the roof edge. For a building with flat or shallow pitched roof the chimney needs to be 3 feet above the point where it passes the roof line. In that case the chimney needs to be 2 above the peak of the roof or 3 above the roof line whichever is higher.
