I am planning to replace the roof in this year. I want to know something about the features that I should look for in order to avoid water leak from ice-dam:
- I know that I should avoid low-pitch roof. I should improve the insulation in the top floor, and improve the ventilation in the attic. What other things that I should look out for?
- I am planning to have a gutter in the roof. But I am wondering what will happen if we have rain and the gutter is filled with ice and snow. Where will the water go to? Will the water go over the edge of the gutter and drop to the ground (this I think will be acceptable)? Will the water somehow go between the roof and the gutter and end up inside the house? Will I have to use one of those heating cable to melt the ice and snow from the gutter and the downsprout?
Thanks in advance for any input on this issue.
