Is it more sturdy that way?

Potentially heavier, but the joists looked about standard spaced. Snow load requirement?

If 1x6's are all that fell off the truck, cheaper than osb.

Me personally,I have never seen anyone use boards to deck the roof,in my life time.Either plywood,or osb sheets is what I have always used and seen used.I know before my time 1x? was used all the time.Is it more sturdy that way?

My dad has a band-saw mill so the inch boards are really cheap. Plywood or OSB would be stronger in some respects it would provide more diagonal support that the boards. As far as just straight downward breaking strength I don't know which is stronger. We added some diagonal bracing on the bottom side of the rafters which you can see in the video if you look closely.

The board are probably a bit slower but in some ways easier. Hauling a 4x8 sheet up on a roof and moving it around can be a pain.

I realize this is beyond late to the party... Laminates (osb) are almost always stronger by weight. More importantly, they tend to be more consistent. That said, 1" boards for roofing are above and beyond "well enough". The only real benefit would be making sure it's a "cold" roof. (Insulating it so the snow falls off, rather than sticking)
