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.
The part of the wall that meets the roof is called the "wall plate" or "top plate." This horizontal member helps distribute the weight of the roof and provides a stable base for the roof structure. In residential construction, it typically serves as the uppermost horizontal framing member of the wall. Additionally, it plays a crucial role in connecting the wall to the roof rafters or trusses.
A longitudinal member in a roof frame, usually for supporting common rafters or the like between the plate and the ridge. One of several horizontal timbers supporting the rafters of a roof. http://www.bw-industries.co.uk/roof-purlins.htm

The horizontal top of a wood frame wall is typically called the "top plate." It is a horizontal member that runs along the top of the wall framing and helps to distribute the load of the roof or upper floors to the vertical studs below.
No. The most common way to tell if a frame is bent is if the roof is buckled.
Tie. Beam is a member which is in tension in a frame
A purlin is a horizontal structural member used in roof construction, typically made of wood or metal. It runs parallel to the roof's slope, supporting the roof deck or sheathing and transferring loads to the building's frame. Purlins can vary in shape, often appearing as rectangular or C-shaped beams, depending on the design and materials used. They are generally spaced at regular intervals along the roof to provide stability and strength.
The frame should be checked prior to the rafters going on. Once the roof is on , you will just have to deal with what you have. The horse is out of the barn...
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.
