This is one of many, many reasons I encourage people who have the land to do so, to do ground mounts. Zero chance of roof leaks that way, and the cost, even with the ground mounts, can actually end up being lower if you don't have a lot of shade. NEC 2017 requires per-panel electronics for shutdown on the roof, and there's no such requirement for ground mounts - so I just have 12 panel series strings going to a string inverter. There's no shade microinverters would help with (my two arrays shade each other a bit in the morning and evening).
