Josh returned after Jim was done and added roof paper and a frost shield which goes along the outer rim of the roof because there is no insulation in that area. The frost shield helps prevent ice from building up. We will need that when it starts to snow, and with the cold front that came through today it feels like that may be any day now. We did live in Florida for the past 25+ years - anything below 70 is cold!
Josh and David seem to like the idea of a safety rope. The next time I saw them on the roof they were wearing mountain climbing gear and hooked into the rope.
