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.
I think it depends on the size of the building more than anything, and your ability to creatively lift things. Given the size, I think you’ll need help.
If there is sheet metal involved in the roof or siding, wear heavy pants and gloves with wrist guards and cut resistance.
