Attic is 30 degrees when 10 degrees outside.

My attic appears to be too warm sitting at 30 degrees when its 10 outside. My house was built in 2008. Has soffits and ridge vent with R38 insulation installed carefully along with baffles in almost every bay.

Im having a hard time understanding why it’s so warm up there. I already checked exhaust fan and ductwork for leaks.

Would lack of air sealing cause this much heat loss? I think that might need to be my next step.

I started getting concerned when noticing ice buildup and icicles on my room in early winter.
