Before I get up on my roof to do roof repair work, I make sure my footwear is right. I don't like to go up there without some kind of non-slip shoes, like the ones you can buy when you work in a restaurant. Check out Austin roofing company for more details. Then I make sure that I have someone to spot me as I work since I don't want to get hurt or fall without being able to get help. Finally, I make sure that the roof is dry and able to be walked on so that I don't slip.
