The roof of our house uses a toothpick type of construction (the roof structure is not prefab). The ceiling joists are all 2x10s as are the roof joists. The 2x4's I put down all span over multiple walls including the main bearing walls. Also, we don't plan on storing anything very heavy. I'm sure the new floor will support the load. If not, I'll post it here!  Thanks for your info.

Sorry, i don't know why but i somehow assumed your ceiling joists were 2 x 4.
2 x 10's will obviously have a lot more strength.
It's all relative to the span anyway.
It all comes down to what load the ceiling system was designed to support.
My attic for example employs rough hewn 2 x 4's (true size) at 16" centres, and is pretty much designed to support just the dead load of the ceiling beneath.
I can walk up there, but only after putting down some plywood boards to distribute the load a bit.
I could never store anything up there cause i have R 42 fibre glass insulation and the ceiling system is just too light.
I wish when they built the place the designed the ceiling as a load bearing floor. Oh well.
cheers
