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.

Images of chimney hieght above the roof. If your peak to penetration distance is 7 feet you would have a rise of 28 inches. 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. But the pipe will require a 10 horizontal clearance from the roof.

Easy calculation for chimney pipe height. For larger structures the result will depend on the roof pitch. So 28 inches plus 24 inches is a chimney height of only 52 inches. In that case the chimney needs to be 2 above the peak of the roof or 3 above the roof line whichever is higher.

Knowing the pitch of the roof is extremely helpful in determining the height the chimney pipe must be above the roof. For the next example you have a shorter chimney height. 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 doesn t necessarily mean the pipe must be above the tallest part of the roof which is known as the ridge.

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. If the pipe is farther than 10 feet from the roof. The chimney must extend at least 3 above the highest point where it passes through a roof.
