Hi there,
Thank you for posting detailed information (it helps to point the problems)
Some notes and tips.
Notes:
- Punch is a Home Design program, this means that the program understands constructively the components that you are drawing. For example, in a drawing program, you draw an element and by editing the mesh, you can convert an element into another one. However in Punch, a wall, for example, can be only a wall, with the constructive elements of a wall and the framing properties of a wall. So, modifications can be created if they make sense constructively.
- The roof that you used is a Ready to Use Gable roof (first tool in the Roof tab) => note that you can't edit the ready to use roofs neither you can add / delete points in these roofs. If you need editable roofs, create your components using the Freehand Roof tool (second tool in the Roof tab).
- To clarify the solutions below, the element that you are pointing in your video (pointed with a magenta arrow in the image below) is called
Fascia

- I created a similar situation. In the image below, you can see the Ready to Use roof (pointed with a blue arrow in the image below), the section that you want to edit (pointed with a green arrow in the image below), and the Fascia (pointed with a magenta arrow in the image below).

Punch, as any program, has a learning curve. The best way to learn the program, IMO, is practice + practice + practice => Read and follow the manual (this is important), see the videos => try to create elements not related with your project, so you will become familiar with the commands and how to manage the different components and effects .
If you are interested, my
eBook for the V21 programs includes a full chapter about roof as well as the images and instructions about 21 types of roofs.
Hope this helps.
(BTW, you website is nice!
