Snow Buildup along Gable and Roof
I have a problem with snow melt on my home’s roof. If there are a snowstorm and snow piles up on my roof along the gable ( see pic ), when that snow melts it gets behind the Hardi Siding. That water then finds it’s way to a window on the first floor and starts leaking into the interior of my home. It’s not a ton of water, but it’s water on the interior no less. This issue only happens when 6″ or more of snow piles up and it never happens when it rains. Just to note there is a rain screen behind my Hardi siding with with RockWool Comfortboard. I think it’s 2″ think or close to that. The siding is attached to furring strips over that Comfortboard. What is a good solution that doesn’t involve ripping out the Hardi siding? I was thinking of adding Raychem WinterGuard wiring on the roof near the gable. This should help keep that area on the roof free from snow. I just don’t even know if that would work though. Most roof heat cable is applied only a few feet up from the edge of the roof and not as high as I need it to go. Any advice would be greatly appreciated.
