I bought this for pretty cheap at an auction and I don’t even know if there are instructions inside. I’m a pretty handy guy with time and tools and some knowledge. I’ve worked on roofs before and know the basics of many other trades.
You can probably figure out how, but actually performing the work entirely alone is going to suck. Even if just to move the large pieces around and hold/lift them in place; you're going to want a friend to help out.
