Sag in the New Roof

This picture shows the sway-back in the roof peak over the new section, apparently caused by a gradual change in the supports for the cantilever.  The sag in the middle of the span is approximately 5 inches from the height of the peak on either end.  The red line shows where the ideal roof peak should run, following a straight line from peak to peak.  A description of this defect with other views from the ground can be found in (Construction Defects, section 7).

The camera icon in this image shows the position from which the above photograph was taken.
