No I wouldn’t. I climbed up an extension ladder that was leaned up against the 2-story farmhouse where I lived when I was 2 years old and got up on the steep roof behind my uncle, who was patching the roof & hammering away. Told him to be careful and not fall. He said his blood felt like it turned to ice, he had to scoot down carefully and get his arm around me and balance and maneuver back down that ladder. I don’t know what he said to me when he got me in the house but I had a phobia of heights and climbing ladders till I was nearly grown. Looking at that photo there’s a possibility that the rock ledge could give way, it has happened before to others.
