Images Of Chimney Hieght Above 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.

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 larger structures the result will depend on the roof pitch. 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.

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. Positing a chimney on the home relative to the rest of the home may cause it to draw better. The height of the chimney above the roof surface measured at the up slope side of the chimney from the roof surface to the chimney top should be at least three feet the green line in our photo.

For the next example you have a shorter chimney height. 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.

Easy calculation for chimney pipe height. 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 doesn t necessarily mean the pipe must be above the tallest part of the roof which is known as the ridge.
