If you are going to start from scratch, why can’t you incorporate a coop as part of the structure? Build a shed type with a gabled roof, this can provide some if the the structure for the run roof. This can also provide a point of division if you keep any separate flocks, if that was needed. With a 25x25 run, I’m guessing a larger number of chickens?
Yes, the structure needed will require quite a bit of wood. We have an elevated coop behind a barn, so protected generally from the worst winds. The coop has a shingled/wood frame roof. Now we are building the structure for the metal and clear panels, but our run is only 10x50, so the 10’ depth is easier to roof over. We are using the coop structure to assist with the roof stability, but also have the main posts cemented in the ground. It is taking awhile and is not yet finished.
Good luck.
