Joining Two Roofs with Different Pitches - Viking Roofing TX Just wanted to let you know that I've re-worked the roof model for this blog post and uploaded it to the Component Warehouse. I have enjoyed reading the theory and practical application to a somewhat seemingly simple framing question. We both posted the same information at precisely 8:06 A.M. ( you apparently beat me by a few seconds)Anyway, I took a look at the math when a 6/12 roof intersects a 9/12 roof at a 135 outside corner, which would be one corner of an octagon. We'll start with the knowledge that the main roof has an 8 / 12 pitch. ", This guy drew a lot of things that can't be built. We never got around to the 135 degree stuff. The wall must be attached to the target roof and the target roof must be a footprint roof. joining two pitched roofs together joining two pitched roofs together Home Realizacje i porady Bez kategorii joining two pitched roofs together. To clarify the offset H/V method I'll "build" and upload an additional off-angle roof model to compare the similarities and differences between the two methods discussed here. Roof framing is a great mind tease after the somewhat simplier thought processes of building the walls and floor. 3/12 and 6/12 is 4.5/17.Is this correct?

If the 2 roof pitches involved were both the same, then the hip would bisect the corner angle, forming two equal 67 1/2 angles with the plates. (Of course, your demo has both ridge heights equal, so either could be considered the Major Pitch, but I always default to the Lesser Pitch as the Major Pitch, for explanation sake. There should be no difference in a roof modeled in SU or framed in reality. See if it reminds you of your brother's formula that you lost.Let URL = the Unit Rise of the lower pitch roofLet URH = the Unit Rise of the higher pitched roofThen the Unit Rise of the Hip or Valley is equal to= (.7071 x URL x URH)/sqrt( (URL)+ (URH) - 1.4142 x URL x URH)In you example, URL = 6 and URH = 9Substituting these unit rises into the formula, we getUnit Rise of Hip/Val = (.7071 x 6 x 9)/sqrt(36 + 81 - 1.4142 x 54) = 5.99Therefore, the Pitch of the hip or valley would be 5.99/12, or for all practical purposes, 6/12.Does that look familiar? joining two pitched roofs together. And, the same geometry found at the plane of the intersecting plates can also be found at the plane of the top of the ridge board.
