Ah OK, things get fuzzy when I zoom in....that big beam must be a 2x10?
1/2"HC will probably catch most of it, unless it is a very fine and dry snow. Time will tell tho. :fl
;)
That's a long span, not sure what dimensions the main beam is or how long that span is,
but it's already sagging a bit.
Curious too about dimensions of cross 'rafters', they look like 2x4's on the flat instead of on edge?
Might want to have some other 'props' ready too.
I had to jam 8'...
