We set up hoses on the roof to simulate a heavy rain, letting water flow across the surface while we check for ponding and leaks. It's messy but tells us exactly where the weak spots are—like that one corner near the chimney where water always sneaks in. This test helps ensure the roof holds up against real storms.
