Sure, lots of strange things happen in a heat wave.
But this is pretty limited and isolated melting. Its not a constant
condition. Over the course of a winter where the temperature stays
cold enough to keep the gutters below freezing and you collect plenty
of snow to melt during daylight hours, you could fill up the gutters
and create ice dams. And I have no doubt that its regions with mild
winters where the temperatures bob up and down above and below
freezing, where this is the greatest problem. But these will also be
occassional dams, not constant. And the gutters will warm up and melt
the ice in them at some proportional amount of time to the roof melt.
Oh hell paint the damn gutters black, its only Ralph's time...we can
spare him for a few hours.
