The last few shingles went up fairly quick despite each needing to be custom cut. We decided that we had just enough time to rehang the window box.
We added a large washer to the lag screw before installing to keep the head of the lag screw from digging into the window box. The screws on each end were installed first. You normally start in the middle when installing screws or bolts over a long area but in this case the window box was long and heavy and there really was not an easy way to prop it up. So we installed the end lag screws and then preceded to install the remaining screws starting in the middle and working our way to the ends.
The sun was getting low in the sky so we will have to wait until tomorrow to attach the brackets.
