The uppermost member of the roof frame is called the "ridge board" or "ridge beam." It runs along the peak of the roof and serves as the horizontal support for the sloping rafters that extend down to the walls of the building. The ridge board helps to maintain the structure's shape and stability while providing a point for the rafters to connect. In some designs, a ridge beam may be used instead, which provides additional structural support.

I don't use oil, but i use a can of silicone spray. I spray it all along the rubber edges of the roof on both the frame and the roof itself. I also spray the lock rods on the roof.
yes
The foundation holds a frame structure up. As for the building, it is a group effort. Load bearing walls hold the roof up, but tend to fall over if the roof isn't there to tie the walls together.
