For 8.5 ft a 2x4 may be ok, esp if at 16" O.C. But from
underneath, if you space 24" O.C. it will look less cluttered.
This is borderline-code in some areas. Whether you will use
asphalt shingles or light weight panels will matter, but some
place may worry that the next owner may use asphalt, and
overburden the structure.
So go to 2x6 and no issues.
The city planners are all dif.
Some use a standard cheat-book, or will help.
Others say, "we can't pass that, or help, but the rafters are insufficient." You say thanks, walk away, scratch out 2x4 and
return with 2x6, and they say, Fine!
2x6 won't sag under the weight of larger potted hanging plants.
;>) Go w 24" O.C. and you recoup the cost of 2x6 over more 2x4
at 16" O.C. and get a cleaner look.
Remember that wind can pick these up with a force of hundreds
of lbs. It you don't address this & it ends up at your neighbors,
you are liable. Up your insurance for the cost of replacement, as they CAN, in this economy, balk to cover it if it is new & not disclosed in your original insurance. That said, Simpson-ties to strap this kite, down, as well as hold it up. Ask at the Pro Desk
of your fav Home Store. Or, there's a Simpson catalog in the
aisles... if you have time to learn this. Ask a Pro. It's easy,
BUT a lot to learn in limited time.
