Just worked with Jennifer Fang, one of my favorite realtors. I was about to stick my poor battered head into a fireplace when she said, "You either need more hair or a hat!" OK, but what hat? Hard hats are too hot and don't stay on when you're crawling around. My Indiana Jones model has a brim that gets in the way and doesn't really help against roof nails. Enter THE BUMP HAT! It's just a baseball hat with a plastic insert along the top. Click on image for link. The right tools are SO satisfying!
