just 3 dew collectors, without mods in fact, i don't believe in putting the new mods in them just to get clean water, i just boil the murky water in campfire when needed; (i don't like being lazy in the game, just because it's an apocalypse doesn't mean i can't make time to boil water on a fire!). maybe the collapse was the structural instability issues that surfaced in v1.0, maybe it was nothing to do with screamers after all; solution for now is to put 2 new dew collectors with the surviving collector, back on the roof; - but i removed the remnants of the original destroyed roof and made an entire new roof and supporting walls; no more collapses so far, (i'm using the Poopy Pants Day care POI as my home; with land claim block and bedroll, but boxes and dustbins within the POI/within the land claim boundary, still frequently repopulate with items (another bug i suspect but's ok, more free stuff 
) ; but no, no farm plots on the roof in this playthrough; (i often have put loads of farm plots on a roof, usually a reinforced roof), never had any structural collapses in A21. my farm plots are 1-block down into the dirt on ground level outside
