Putting a roof on a House

Hello, thanks for any help beforehand. I am, modeling a house I started with a plane and I now have a “U” shaped object, I want to enclose it now but I can’t seem to figure out how to.

.blend here House.blend (402 KB)

And now I feel like an idiot just select the two verts and hit f Thanks any way

Actually you probably want to have the roof separated from the building model. One of the many reasons being that a roof will generally extend beyond the building that it is attached to.

I have attached a blend file that should show a better method of making a roof.House.blend (1.65 MB)
