I'm not sure about my job yet

First big project on my own this is!
I'm making a double car port. It has 9 4x4 legs.
Roof is going to be supported by 2x4's and made out of corrugated
plastic.
The plan i found recommended 2x6 but the guys in the builders merchant
reckon this is overkill (it being floor joist spec) and they had none
in stock for the next week.
My house has a flat single floor extension on one side. that has a
roof made of 2x4's so i reckon it should cope.
The only thing im not sure about yet is how to attach the roof section
onto the legs. Screwing onto the sides of the legs would be easier and
visibly tidier and is what my plan calls for - but surely resting it
on top would be stronger? but much harder to get right (since id need
to cut the legs perfectly in-situ)
Im also debating how to cross the struts. I Should probably cut little
'U's or 'n's out.
How much does snow weigh anyway?
The carport is roughly 16ftx16ft, so with 9 legs could be considered
as 4x 8x8ft squares each with 4 legs. Perhaps i should look into the
weight of snow per square foot.
