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.

This will generally cause you fewer problems as a homeowner. For larger structures the result will depend on the roof pitch. What is the 2 foot 10 foot 3 foot rule. 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 the next example you have a shorter chimney height. Per the 10 and 2 rule once you are at the level of the peak you only need to be 2 feet above it. But the pipe will require a 10 horizontal clearance from the roof. If your peak to penetration distance is 7 feet you would have a rise of 28 inches.

If the pipe is farther than 10 feet from the roof. In that case the chimney needs to be 2 above the peak of the roof or 3 above the roof line whichever is higher. Positing a chimney on the home relative to the rest of the home may cause it to draw better. The chimney must extend at least 3 above the highest point where it passes through a roof.

So 28 inches plus 24 inches is a chimney height of only 52 inches. Knowing the pitch of the roof is extremely helpful in determining the height the chimney pipe must be above the roof. This doesn t necessarily mean the pipe must be above the tallest part of the roof which is known as the ridge.
