Hottest day so far this year...
Used the engine hoist to get the balance of the roof frame over the back of the roof.
Pushed, prodded, and finessed it along the roof until it met the front edge. Pried it over the edge with a couple of hammers. I put blocks under it to prop it high enough for a huge bead of caulking underneath it tomorrow. Then I'll drop it down right on the roof.
Straightforward and relatively simple installation. Not easy but I did it solo in 4 hours. Amazing part is how unstraight 14 feet of 3 inch angle steel actually is. I had to put a spreader at 7 feet to push it out to the required width.
