I would think it would be sufficient to support the roof load but your load
is something else... not the beam but 2x2 trusses ??? is this an
engineered truss or something you've come up with... I covered my deck
12'x24' with 2x6 roof rafters supporting metal sheeting (22 ga) with 1x4
sheet 'girts' set flush with the top of the 2x6s (notched in) ... and it's
all sitting on a double 2x6 beam on the outside end...overlapped about 3
feet and bolted in 4 places with 1/2" bolts and nailed about a hundred
times... it's supported by 4 4x4 posts (8' centers)... it's held a 12" snow
for about a week and I routinely climb on it to clean gutters... although I
limit my steps to the rafters and the bridging...
I just don't know about 2x2" material and can't picture a 2x2 truss in my
small mind...if you're still antsy about it, sandwich a piece of 3/8" or
1/2" plywood in between the 2x8s before bolting and you're surely good to
go... BTW a double 2x8 ?? you're gonna need some help to set that up there.
