Would cool roof shingles increase our heating costs with cathedral ceilings?

Our home has a sloped roof, located in Kingston NY area. About one-third of our roof is over an attic, the rest of the roof is over cathedral ceilings. I understand that cool roof asphalt shingles reflect the sun which in turn would reduce cooling costs, but that cool roofs may actually increase the heating costs in the winter months in cold climates, since 'reduced attic temperature from lost radiant heat will encourage additional convective heat loss from the house' but not sure how that would apply with cathedral ceilings. I don't know what insulation exists in our cathedral ceilings but our heating costs are good compared to our neighbors. Any info to help finding a green roof t that would reduce cooling costs would be greatly appreciated. Thank you.

Installing cool roof shingles on your home will not increase your heating cost during the winter months. Heat will always move from the warm to the cold, this is known...
