I want to install vinyl roof on my terrace under which I will do exercise. I can do it in open terrace but it is quite irritating in summer season. I don't know how to make it happen because, I have no facility to drill down any thing on terrace. Can any one suggest me. I am going to buy 4 iron rods, 1 square vinyl sheet and other tools... Right now, I don't have photo but, if you recommend so I can attached over here.
