I have been doing more lighting projects lately where we light up the house, as well as the landscape. (In the past, we had only ever done lighting on decks and landscapes mostly.) I have a customer who we've done about $10,000 in lighting for already. He asked me recently what more we could do, in terms of lighting. One thing I mentioned was lighting up his house more, specifically the peaks at the top of his two roof lines. He's very interested in a bid. Well, that's where it gets tricky. It would be very difficult to get a ladder up to these peaks. They are above and slightly behind other peaks. Not to mention they're like 30' up in the air. So ladder really isn't a viable option. Which means we'd have to get someone up on the roof laying on their belly, to install these lights up at the peaks of the house. And although I sure as heck ain't doing that - I do have a guy who will. He's a friend of mine who used to work for one of my lighting suppliers. He knows lighting and he did the same thing at my house. Only thing is these peaks are twice as steep as the ones at my house. And I am afraid he'd fall off. So how do I prevent that? What can we do to make sure he doesn't fall off and plummet to his death while he's installing these?
