Why Doesn't The Roof Ever Leak Over a Bathtub?

Hoarder's Paradise

Fucking hell, the rain was predicted but I could not finish the laundry room modernization of this garage before it hit and forced me to bring my toys off the lawn. Bummer. The garage roof leaks terribly but I knew it would. I didn't know the floor would channel it everywhere and create a mess. The house leaks badly too and not in places I can find....due to there being two roofs.
