Images Of Chimney Hieght Above 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.

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. What is the 2 foot 10 foot 3 foot rule.

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. This doesn t necessarily mean the pipe must be above the tallest part of the roof which is known as the ridge. For the next example you have a shorter chimney height. For larger structures the result will depend on the roof pitch.

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. 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. Knowing the pitch of the roof is extremely helpful in determining the height the chimney pipe must be above the roof. 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. 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.
