I have a gambrel roof and need to fix an ice damming problem. I’m redoing my roof next week and want to help my ventilation while I’m at it. I live in NY where we get snow and a good amount of it. I have ridge vents and plan to install new when I do the roof, I will also be using gracie ice and water. Back of the house is identical minus the porch dormer.
In the past I have shoveled off the roof everytime it snows and, well…fuck that!
Opinions on smart vents???
Do they work?
One worry I have with the smart vent is: if I still have ice damming the water backing up into the slit I put in the roof…
Should I not cut a vent slot in the roof above each dormer, will that make a difference?
Any assistance is appreciated.
