A greenhouse on your roof, what kind of crazy ass would do that ?? At least it wasn’t snowing 🤣
…Made from skids, scrap wood, and 6mm poly vapour barrier.
You could build the frame with electrical conduit and cover it with plastic sheeting. U would have to price it out. supplies are going through the roof.
suggestion; I used to work in the nursery industry. A metal frame greenhouse kit with poly-carbonate panels,. they come in different sizes. Put a screw in ground anchor in all corners and one in middle of each wall, for one about 6x6. I would add angle braces in walls for added strength.18"-24" exhaust fan on thermostat, I'm using ac filters in the door for air flow. A little ele. work for lights etc. A basic DIY project. Note; 4x6 starting at $175 on TEMU:smile:
