we measure it with a string and a line level usually and honestly if your new construction roof changes pitch that much I would be on the builder about it. but that is just me. I know mine varies but it is 100 years old

yes we use a 10 ft string with a line level on it drop it down till it meets the roof then measure what you have above that line.
I agree that if it does change they probably messed something up but it looks well over the 10 foot rule to me.
It might be we cant tell anything from that pic though you just need to get up there and measure it. But like I said before if your draft is weak and you have a pretty short stack I would add to it anyway.
Thanks bholler for all the advice I just had one more thing that I thought about. When it says I need a roof guy kit for 5 feet of chimney pipe or more. I measured from the roof to the top of the pipe. Thus, I included the flashing. Is the flashing height included or do I measure from the pipe out of the flashing up on the uphill side?
it is from where the chimney exits the roof deck so yes you were right. But that should all be spelled out in the instructions.

If you don't keep the rulers plumb and level when measuring that can easily throw off your measurement.
Another thing that I noticed is that the two foot section of chimney pipe that is now in my room is crooked. At certain angles it looks straight. However, when you look at it dead on as you enter the room it goes crooked to the right. I tried to nudge it to the left to get it to straighten out no go. When I had a few inches in the room, all was straight. Why does it look crooked now, is the 2 foot piece bad? Is it because it is too long maybe try a one foot section to see how that looks?
P.S. my setup is a cathedral ceiling support box.

That is marginal for satisfactory performance. Take it up to15ft if you want the stove to behave well.
Is the support box level and plumb in all directions?
PS: Can you remove the saw wanted line and add your stove to the signature?
Okay, so I got on the roof took rope measured off ten feet and leveled it with a level. I am at 4 ft 9 inches pipe out of the roof.
When I leveled the rope I got that I have 20.5 inches of chimney past the ten foot rule.
So, I know the codes require at least 2 ft but will 3.5 inches of pipe really be necessary?
Also, if I add the half foot section and lets ay it is 4 inches in length realistically. Then I would be at 5 ft 1 inch.
So, if I do this would I still have to add the brace kit. I know most are saying just add it anyhow and be done with it. But, if I can avoid it why not avoid it.

Yes, begreen the box is a little off level to the right. The right side actually need to come down probably less than eight of an inch. Attached is pic of level on support box. I knew this when it was put in though. . I think that the pipe is crooked? I think the collar that goes around the pipe that is inside the box was put on slightly crooked but if it was why was it easy to get into the flashing? Huh? Maybe my new 2 ft pipe is crooked?

I've never run into crooked pipe. Seems like that would be hard to get by QC.
hey begreen I think my setup looks crooked because my single wall is a little crooked on the stove pipe adapter maybe I need to move the stove to the right and re screw the pipe into the adapter. Can this make it look a little crooked?
Also, as far as the chimney up out of the roof. Since I am only of by a little bit can it wait till summer for me to mess with it then? Is the pipe okay up there at 4 ft 9 inches without a brace?

read your instructions it will tell you when you need a brace and read the instructions for he stove it will tell you how tall your chimney needs to be. and to meet code you need to add to your chimney
Can I wait and fix the chimney over the summer. After all it is only 3.5 inches? But I am gathering it is necessary so it looks like I will ad the brace kit anyhow.
The reason I want to avoid adding the brace is because I am switching appliances. I am swapping the 30 for the englander furnace.
Therefore, the furnace does not call for a specific height of chimney. So, bholler do you think i could get away with the 6 inch section or no? It will be just at five feet or an inch over?

every ul listed appliance I have seen calls for a minimum stack height (most are 15') but id check the furnace you will be switching to to be sure what they call for. I cant tell you for sure one way or another but if it were for a customer of mine I would add the 2'.iI mean really it cant cost that much more and if you already are going to need the brace why not?
Have you stopped burning for the year? If so, sure. If not, add the extra pipe and brace when you get a decent day for it. The extra 2 ft of pipe will improve draft, especially in milder weather.
No, I have not stopped burning. However, I only burn when I am at home. So, The extra two feet will wait till next year. I am just shocked that I measured 3/12 on the roof the first time?
I forgot to ask when I install the roof guy kit, the manual just states to nail the two legs in place do I need to hit a stud though?
