Working Late

It has really been quite hot the last few days. My husband is a contractor who is currently in the process of shingling a house. This afternoon the temperatures were so high that John and his crew decided not to work this afternoon because of the heat. When I finally got home from work today he informed me that he was going to shingle tonight when the temps were cooler. I didn't think the temps were very different tonight then this afternoon, however waiting would mean the sun wouldn't be directly over them, which will make a big difference up on that hot roof.
