I was taught to split the different pitches thus coming up with the hip pitch.
Joining two roofs with different height face.
The overhang is 16 inches measured horizontally and the fascia runs at a continuous height around the entire house.
Identify the roof areas that you will join.
The next step is to raise the building extension to the correct height.
Select the 2 top faces.
Put on a pair of work gloves.
In the pop up menu then choose calif ranch from the roof style pull down menu.
Remove the shingles and underlayment on the edges of both pitches approximately 6 inches from the edges using a shingle.
The other is to get the fascias to line up.
After a taking some measurements and doing a bit of ciphering we established that the steepest pitch we could use on the porch roof was 4 in 12.
Then use the slope arrow function to draw a line from say the inside of one supporting wall to the ridge then repeat for the other side.
Choose plugins instant roof make roof.
Joining two roofs with different pitches is a method that exists in the building and construction world.
3 12 and 6 12 is 4 5 17.
The easiest way to do this is draw a footprint roof with whatever overhangs you want.
Draw a ref plane centralised between your 2 supporting walls.
If by any chance right now you are looking for the information about how to join two roofs if they have different pitches here we will share all the information we know with.
One is getting the two differently pitched planes to meet at the hip or valley rafter.
Joining these two roofs poses two main challenges.
I have only built one roof where a hip was joining two different pitch roofs at the corner of a house.
