Hi Mark That the ice is in your gutter is probably a good sign....as it appears to be melting closer to the gutter than the ridge....probably due to the ridge vent you installed. A really bad sign is when the melted water starts running down into your living spaces....:-(
What Jay J says is right on. Having a Cape Cod style house with heated living areas under the roof is a challenge to keep the heat from escaping and melting the snow/ice in contact with the roof surface.
If the area you live in Ohio doesn't get to warm and/or the sun doesn't beat down on your roof to hard in the summer, you could consider having cellulose insulation blown into the rafter spaces from above or below, for which you would have to temporarily remove your ridge vent or gutter/facia boards, respectively.
Another option is to attach rigid insulation to your current second floor ceiling. Ok, this won't look too good, but it should help prevent ice daming during the winter months.
Another thing I would do is build a scaffolding up to your facia boards. Remove the gutters and look at where the facia meets the rafter tails. You should see a small gap there. You can widen this gap by either cutting out an inch or so of the facia with your circular saw or drilling several small holes into each interrafter space, being sure to cover them with a screen to keep insects out. The reinstalled gutter should not cover these holes or the gap you have created. It will allow more outside air to get up under the roof deck, move along the underside of the deck and exhaust out the ridge vent. This should go a long way in helping to prevent your ice dams.
