That’s just a plan of the roof to understand what’s there. There are many ways to approach the roof forms. Because you have Pro and because of the general shapes, I am going to use SOLID TOOLS.
First a new group of the roof outline to the eaves. I divide the surface like this. A rectangle for each gable shape and group EACH rectangle separately. Be sure that each side is a single edge no breaks (remove lonely vertices plugin, or CleanUp repair edges) (or erase extra vertical edges after next step).
In each group push pull up the rectangle for the side fascias, draw the ridge line and, marking the angle of roof with the protractor, pull up the ridge edge, while pressing the up arrow key to meet the guide created by the protractor.
Now you can open one of the gable form groups and push pull it’s end to the ridge of the next one. Starting with the largest, then the second largest…
Use Solid tools to combine the forms.
Then you have to move the end point of the high gable back to form the hips. Use the move tool click on the point and move in the red direction. Move the cursor onto the opposing slope to inference the point to be coplanar. Then you can remove the edge where the fold was made.
Marking the hip with a guide copied off the valley and drawing a line for your fascia. Fold back the big roof form to be a hip roof, moving the top point as before, to the intersection of the guide and ridge.
There’s a little pyramid left over at the low ridge / hip intersection. just draw the hip line and erase the excess (red).
Now using offset tool you can draw your soffit line (in this case the wall line), and gable fascias. Draw edges to define the cornice at each gable.
Push pull the gables in to the wall line or what have you. (Erase the extra edges.)
