Ok I have brought this up before but im looking for ideas on a situation;
I have an addition that has a gabled roof tied into a hip roof Southern exposure. Where the valleys end i get an ice build up there.
Before I had my new roof done 10 yrs ago one time water came in right under the valley overhang. The new roof has ice and water on both roofs and up the valley 6 ft over lap each side.
I also had a roof de-ice cable on this area running into the gutters which worked very well if ice built up and you turn it on for a day it would melt big channels and thaw the gutter all the way up the valleys.
Now there is about 8" of snow on the roofs and its about 26 degs here. I have a small amt of ice probably about 1/2" under the snow at the edge.
The attic is insulated R40 with baffles and full vent ridge on the house and addition. If you look at the roof with a heavy frost it is covered NO bare spots.
Soffit is about 12-14 " wide and full vented so I know air flow is NOT a problem nor is heat loss. Could it be because its facinf the South where the sun is ??
My fear is I dont want it coming in again even though it never did with the new roof. Would I be better off putting up the metal ice belt edge in this area so if we go on vacation in the winter I dont have to worry ??
What ideas do you guys have ??
