Hello. I have a 12' x 16' sunroom with a metal roof that leaks in the winter, when snow starts to melt. I think the problem is due to an ice dam. The metal roof of the sunroom connects to the house immediately below a section of shingled roofing.
I know why ice dams occur, but what can I do to stop this one? It's a nightmare when the roof leaks in the winter. I would definitely appreciate your suggestions!
Here are 4 pictures of the sunroom roof. I've included labels to help with the diagnosis.
