Hi. I’ve gotten conflicting advice on this topic. One contractor believes that if I install ventilated drip edge I run the risk of water backing up into the attic in the winter if the gutters become full of ice. Another says that there will be little to no ice buildup in the gutters if the attic is properly ventilated using ventilated drip edge along with ridge vents (provided the gutters are kept clear, of course).
I currently have a ventilation fan, so I could just keep it and install lourves for air intake.
So my questions are: Should I go with the fan and traditional louvres even though it is less asthetically appealing and uses electricity (not to mention that I may have to replace the fan if it ever breaks)? Or do I go with the ventilated drip edge and ridge vents and run the risk (if a risk even exists) of water backing up into the attic during winter?
Any input would be appreciated. Thanks!
