Has anyone use the roof kit with another rope tied to your truck. I'm thinking of doing this or just having a rope with me tied to my truck so I can hang onto it while on my metal roof. I'm leery about going on my shop roof without having something hang to. Pollen almost caused to slide off. Still need to check the screws and redge cap. I'm thinking about having spray foam coating put on roof so it will seal any and all leaks and I won't have to get up there any more.
