great video, so the difference always reduces the height of the wall on the lesser pitch or increases the height of the wall on the steeper pitch correct?
This was a good video. i have not ran into this situation... yet. but you explained it well. need to see the video a few more times to understand how simple the calculation can be. i know i would take hours solving the problem on my own for the fist time.
Nice video thanks for the information, I just wanted to ask if you have two different pitches like you have in this video, won’t there be a problem when you come to the roof valley or is it possible to have a roof Valley even if you have two different pitches, I would appreciate your knowledge on this.
Thank you for this awesome video. What I don't understand is that by changing the wall height, why is the pitch not changing not changing? I guess what I mean is that if pitch is calculates with rise and run...if you change the rise by adding to the top plate, why is the pitch not changing?
Yes you make a good point, if you change only the height of one wall, and not the height of the ridge associated with that wall's rafters, the pitch of that roof will change. That would alter the required change in wall height and cause the birdsmouths on that wall's rafters to not sit correctly. To change only the wall height and not the associated ridge is a problem more complicated than I can comprehend. What do you say @gregvancom
Nice video what I've always done is draw the two tail drops and the intersecting point at the wall plate on a sheet of plywood then make each tail pattern to use when the roof framing starts
I'm trying to build a small greenhouse and I know how to calculate rafter length, I know the pitch desired, but I am struggling to figure out how to determine the height of the height that the wall should be framed at and what the height of the ridge beam will be. Can you point me in the right direction?
@@gregvancom I'm trying to stay under 13ft because my municipality is strict about height. So I know I want a Ridge beam no more than 13ft high, and I know how to determine rafter length but I imagine rafter length is directly correlated to the height of the wall, if you want a specific pitch. I will look for those videos. Thanks.
Love it when a professional shares and explains the process.
You are awesome been saving me couple of times already 🙏🏼🙏🏼🙏🏼

Thank you, I have had this problem that I couldn't figure out

Thanks and watch it until you understand.
Love the information, it makes the World go around! ✌️ Thank You
Yes it does!

Not sure I am following. The difference in wall height from calculating was 2 5/8. Where did the 4” measurement come from?
Thank you for the very informative videos but I am struggling to understand/workout the fractional figures

This example has two different roof pitches. One on the right side and one on the left of valley.
It will change if you raise it 3.”
And it’ll screw up the tie in on top too

Nice explanation 👌
Thank you 🙂

That's a great idea!
So basically your soffit measurements would never be the same with different roof pitches if you didn’t adjust wall heights or seat cuts on rafters?
For the most part yes.
Need help working out a 4inch overhang for 4/12 and 5/12 pitch roof joining tigether for fascia lines.
If this didn't help, I would need more details about your problem.

Usually you can use wall heights seven feet or taller and I have a lot of videos on roof framing at our website that can help.

What happens with the ceiling heights?
Usually the ceiling height is based off of the lower walls.
Lol 🤦♂️
