Rather than doing them as 2 separate roof sketches and joining them those 2 parts of the roof can easily be done as a single sketch.

1. Where you want the gable, split the line into 3 pieces. 
2. So there are break points where you currently show the valley's. 
3. Then draw two slope arrows going from the valley line to the midpoint of the middle line (for the line you've just split into 3).
4. Select the slope arrows and set their levels and falls appropriately to match the rest of your roof.
5. Finish Sketch

This may be a little tricky to follow without a picture, I can't remember but I may have posted something on my blog about this some time ago or at least something in the forums.  If you can't follow or find it then please let me know and I'll post a screenshot.

I think I am going to need a visuial... I keep getting an error saying that the roof footprint can't be made, and I don't exactly know where to split the line because the far left valley is in the corner of the roof.

I'm having the same problem but can't access the video. Help! What was the solution?

You give the gable its own manual slope arrows, like in the attached pic.  Slope arrows are more time-consuming than slope defining boundary lines, but more powerful.

There are breaks in the boundary which exactly match the lengths of the two slope arrows. 

so break-break-break the boundary, and draw two arrows over the remaining segments.

I was able to join a hip roof to a gable roof by doing the following:

1.- choose roof by extrusion

2.- In skecth mode I skecthed the shape  and hieght of my gable roof( it is important not to have a closed loop when using the extrusion tool).  For the roof by footprint tool you must close the loop. Hopefully this step should solve your problem.

3.- Now that I created a hip roof using the "roof by footprint" tool and created a gable roof using the "roof by extrusion tool", I can now join the hip roof to the gable roof.

4.- I chose the the join the roof command, clicked on the edge of the hip roof and clicked on the edge of the gable roof.  Now both roofs are now joined. Both roofs are joined. However, I have not figured out why when I click on one roof, why both roof don't highlight as 1 whole roof.

If someone can explain to me step 4 further, I would appreciated it.
