I don't see how it's a partnership if you're putting in all the initial capital. I understand that he has all the roofing experience, but there is zero risk for your friend and I would not be comfortable with that. If I were you, I would make myself the primary owner and give my friend a fancy title like executive vp of sales and operations or some bs. You'd have to work out a base salary, but most of his money would be made on commission per job and also some sort of commission for sales leads. There could be a clause added to the contact that once the company is established, your buddy would have an option to buy into the company for half the amount you put in to start or something. A partnership with 0 investment is a no lose situation for anybody and that really could put a strain on the relationship...
