The roof on my church has developed discolored spots all on the western side of the church. I contacted the roofer and was told that the spots were called hot spots and was not a discoloration. He told me to take a rag and wipe off one of the spots and there should not be any color come off on the rag. Well, I did that and there was color on the rag. What exactly are hot spots and how can they be remedied? Is it a ventilation problem?
