My house is an 1855 gable front house and accumulates lots of icicles. It has been professionally insulated. It has open eaves and is therefore the eaves are not ventilated. There are roof vents. I was wondering if anyone knew how to reduce the amount of icicles I have. I don't want to close the eaves in order to ventilate, as I am in a historic district and I want to leave that feature.
