Susan & I did the roof of our A-Frame by ourselves back in 05. 24/12 pitch. 35 square of 30 year Architectural Grade Shingles. Roof brackets with planks every 4 feet. Peak is 37 feet from the ground. She humped em up to the first bracket plank. I brought em to where I needed them & nailed em down. Took us 1-1/2 months working every night after our day jobs & on weekends...I did the ridge vents & cap shingles straddling the roof at the peak. Legs were at a 60 interior angle for so long that I couldn't ride my Sportster for a couple of days. Actually burned my inner thighs from the heat absorbed by the black plastic ridge vent. I will admit that I was in the best shape of my life since Basic Combat Training in 71...
