Dropped the roof frame the last inch or so into place onto a thick layer of caulking. Started installing the perimeter screws. I'm using galvanized metal roof screws with the washer and gasket. Each screw hole gets a small dab of caulking before the screw is driven home. I don't want moisture under the frame.
The frame was a tight fit. I had to climb along the roof and jump on the frame to get it bottomed.
I installed a drip edge under the back angle to help steer rain water from the roof away from the rear doors.
