Chimney Pipe Height Above Roof
The chimney should extend at least 3 feet above the roof surface it penetrates and 2 feet higher than any roofline or other obstacle within a horizontal distance of 10 feet.
Chimney pipe height above roof. The finished height of a chimney needs to be 3 feet above the highest point of the structure or 2 feet the flue connects the top of the smoke chamber to the roof through the middle of the chimney. Stove pipe inside counts as part of the chimney length. The minimum length above the roof is 3 this is why some industry people use the term 2-3-10 which means 2 above anything within 10 and a minimum of 3.
If at 50 high vertically off of the roof you hit the roof 10 feet away you need to add 2 feet. This will bring the total height of the pipe Not including the cap to 85-inches. For most small structures like small cabins and tiny homes the tallest part of the structure is within 10 of the chimney.
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 means the 3 foot height must be measured from the roof on the upper uphill so to speak side of the roof at the base of the chimney. As your 8 inch flue is the biggest hole it pulls the smoke down the pipe into the.
So 28 inches plus 24 inches is a chimney height of only 52 inches. Taller chimneys make more draft but chimneys exposed to outside cold dont. If the flue outlet on the roof close to the edge and remote from the ridge point further 30 m its height determines the line drawn from the point of the ridge to the chimney at an angle 10 0 downward from the horizon.
Your main driver is the 15 feet minimum. If the pipe is farther than 10 feet from the roof peak it must be 2. In the photo below you can see where the braces currently attach 41-inches above the collar.
The location of the chimney on 15 30 meter from the center of the roof require horizontal pipe height at or slightly above the Level of the ridge. If your peak to penetration distance is 7 feet you would have a rise of 28 inches. In the case of stainless steel system chimneys the manufacturers installation instructions should be consulted.
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 termination cap is installed above this point. This reduces the actual required height by 12 inches from our previous calculation of 64 inches.
The chimney opening above the roof of a sticks and bricks house should be 3 feet above the roof line or 2 feet above any part of the building within 10 whichever is higher. The height of the chimney pipe above the roof plays a big role because if the standards are not followed the system becomes ineffective fuel consumption increases smoke is drawn back into the room and fire safety is reduced. 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.
The top of the chimney pipe must be at least 2 feet higher than any part of the roof or building that is within a horizontal distance of 10 feet from the top of the chimney pipe. Therefore if you draw a 10 Radius around your chimney the flue needs to be 2 above everything within that radius. Prompted by a question from a CSIA Certified Chimney Sweep Ashley Eldridge in his 21st year as the Chimney Safety Institute Director of Education talks ab.
If the chimney extends more than 5 feet above the roofline an Extended Roof Bracket must be installed at every 5-foot increment of chimney height above the roofline leaving no more than 5 feet of chimney extending above the last pipe bracket. 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. See our section on chimneys.
The maximum freestanding stack height above the roof for a traditional masonry chimney is 45 times the narrowest horizontal part of the chimney. Hopefully this will be enough. Chimney height regulations Chimneys need to be high enough to ensure that smoke is directed away from where it might be harmful to your neighbours.
Currently the pipe is 6-inches above the roof peak. The main criteria and requirements for the design of the chimney.
