Images Of Chimney Hieght Above The Roof

If the pipe is farther than 10 feet from the roof.

For larger structures the result will depend on the roof pitch. This doesn t necessarily mean the pipe must be above the tallest part of the roof which is known as the ridge. 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. What is the 2 foot 10 foot 3 foot rule.

Positing a chimney on the home relative to the rest of the home may cause it to draw better. Knowing the pitch of the roof is extremely helpful in determining the height the chimney pipe must be above the roof. 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.

This will generally cause you fewer problems as a homeowner. So 28 inches plus 24 inches is a chimney height of only 52 inches. Easy calculation for chimney pipe height. If your peak to penetration distance is 7 feet you would have a rise of 28 inches.

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 is a bit of an odd measurement and chimney clearance case because the chimney side is actually about 8 away from the roof edge. Per the 10 and 2 rule once you are at the level of the peak you only need to be 2 feet above it.
