Lean to build question ?

[Dtim]

I'm building a free standing lean to with a metal roof next to a 40 x 40 steel building.
My question is can I tie the 2x6 rafters on the low side directly into the face of the 2x8 header? as opposed to setting the rafters on top of the header ?
This will give me a little bit more headroom on the low side, and seems to me to be a more solid structure...

Thank you in advance

^^^Well that's helpful, huh? I'm having a hard time visualizing what you are saying, seems like you would have more headroom putting the 'rafters' on top of the header?

...you can do this rather simply, I just built the same thing,...install the poles, attached 2 cross pieces,then the end pieces,the remaining cross pieces then plywood sheeting, felt paper then metal roofing. you don't need to fasten to the building if you have an overhang on the building.

yes you can if you want. I would bolt it, instead of nailing

instead of putting hangers on the existing 2x8, bolt another 2x8 to the face of the existing header

^^^ mine is bolted to the posts and also screwed together with 3" deck screws...

Thanks for the pictures Rusty1 ! and all the responses and good suggestions. The headroom I am referring to is going under the header board on the low side since both sides will be closed in. I'm building under the existing overhang. So for a 12' wide roof starting at 9' on a 3/12 pitch, my headroom under the front rafter would be about 5' 3".

Just wanted to make sure there wasn't a good reason to have the rafters on top of the header.

Rusty,
What influenced you to run your rafters long ways?

I’ve always ran them the shortest span possible so I’m curious for the reasoning.

Thanks,

I bet he is going to use the same metal roofing that is on the garage.

^^^exactly,...I wanted to use the same metal roofing as the building so I ran the "rafters" longways, I could have run them short ways , but then would need nailer boards running long ways to nail the metal down,..doing it this way saves material , time and added weight....and I used 2x6's for the added strength.
...I spose with the plywood over the rafters, it wouldn't matter which way therafters were run, but running them longways makes for a stronger, fatter roof I think.

...I wanted the slope on my lean-to be the same as the slope on my building;...but you wouldn't have to have them match for more headroom at the lowest point...
...my deck is only open at the ends , there is almost 6&1/2' clearance at the lowest spot.
