Images Of Chimney Hieght Above The Roof

Positing a chimney on the home relative to the rest of the home may cause it to draw better.

For the next example you have a shorter chimney height. But the pipe will require a 10 horizontal clearance from the roof. So 28 inches plus 24 inches is a chimney height of only 52 inches. This will generally cause you fewer problems as a homeowner.

The chimney must extend at least 3 above the highest point where it passes through a roof. For larger structures the result will depend on the roof pitch. What is the 2 foot 10 foot 3 foot rule. 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 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. 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.

Easy calculation for chimney pipe 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. 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.
