The 150m2 of slate roof that I spent the first 'lockdown' replacing, had suffered multiple leaks for years, with at least a dozen bowls placed around inside the loft to catch the drips. After it had rained, there was varying quantities of water in these bowls, but after a week or so without rain, most of them would be bone dry.
I suspect that if something with a reasonable surface area, such as a washing up bowl, was placed in a reasonably well ventilated loft, so as to catch the drips from a condensate trap, its contents would evaporate faster than it filled.
