Here’s an attic from a home built in 1950. All of the rafters and ceiling joists look to have been spray painted white. Underneath the white the wood is dark, almost black. If you can zoom in enough you can see how some of the rafters look like the white paint is cracking, almost like a blistering. I don’t believe there has been a fire. My question is does anyone know what a creosote covered piece of lumber really looks like?
