Isn't not slate but, it happens every time you don't maintain the snow. With in three days up to 8 in of ice. This happen in Vermont last weekend. I know that the warn water from the glass above comes done to the cold copper and it starts iceing up. What do you do? Heat tape is not answer.

Yes, they are different to the left is a 12/14p and to the rigth is a 8 or 10/12p. The copper is over lapped from 4 to 6 in. The valley exsposure is tapper from 5 1/2" to 3" @ the top. There is a wash on the rigth under the 18' of ice (block copper about 3' tall x 5 wide). Head lap I think there is 3". There is standing below the valley and there is a deverter for water under all that ice. The water would go in to the window with out it because of the lay out of the house. The inside corner is not a square.

Is that two different slopes that the valley is draining? Do you know how far under the slate the valley metal extends on either side? What is the valley exposure? Is that a low slope roof section on the right? What is the headlap there?

I've seen this happen on a couple of projects, one way to fix it is run a heating cable zig zaged on the 1st 3-4' up the eave.
Such as this : http://www.heatersplus.com/easyheat.htm

We had a project that was around a 8/12 pitch but had a large trough shaped cricket, in the winter the snow would pile quite high, the warm air from the attic would make the bottom layer melt & leak into the attic.
THis cable fixed the problem permanently.
