How High Should Chimney Be Above Roof Peak

If you go through the peak you need 3 feet.

How high should chimney be above roof peak.

Anon the chimney outlet needs to not only be proper height above the roof surface but proper distance from any opening that could take flue exhaust. And at least 2 higher than any portion of a building within 10. 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. If your peak to penetration distance is 7 feet you would have a rise of 28 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. I had the roof you see in the photos done in 1991. That is correct but the chimney has to be at least 3 feet high overall. The 10 foot rule explains the clearance you need.

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. The stove pipe wasn t far above the top of the roof and wind blew smoke back into the house. This doesn t necessarily mean the pipe must be above the tallest part of the roof which is known as the ridge. The chimney must extend at least 3 above the highest point where it passes through a roof.

Easy calculation for chimney pipe height. Don t forget to add in minimum chimney height. I used to have a flat roof on the house. 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.

They intend to make sure that the chimney draws properly and that a fire hazard does not occur. Both above the flat roof and 2 feet above the point at which a horizontal line from the chimney would touch the highest portion of the nearest roof. Knowing the pitch of the roof is extremely helpful in determining the height the chimney pipe must be above the roof. Specifications aren t there to merely cause you problems.

So 28 inches plus 24 inches is a chimney height of only 52 inches. 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. For larger structures the result will depend on the roof pitch.

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. I have heard that the top of a wood burning stove pipe needs to be a certain height above the peak of the roof to work properly.
