About done roofing

With any luck we will finish the corn crib roof today. It is late May, correct? That was when I hoped to be done with it. Oh well, we did 3 roofs at dad's and this one. This one became a much bigger job than we anticipated. Now all I have to do is pick up all the ... I hesitate to use the word trash. Construction residue?

I'll try and post a photo later. Off to climb on the roof.
