When I have looked at it (usually for pre-engineered metal buildings)- the lbs/sf is just the weight of the water-filled pipe divided by the are it 'covers'. Similar to the coverage of a sprinkler head.
Each structural member then has an allowable point-load formula based on how the connections are spaced and how much load it can handle. Most of the PEMB designs I come across have a 5 lbs/ft "collateral load" design. We have never had a sprinkler system exceed that.

I'm looking for a table that an architect or engineer would use to figure roof loading. I don't think they're that detailed.
