MY bathroom upstairs has the ceiling just a few inches away from the roof decking,
I have the space almost filled to the decking with insulation.. 4" space left for air circulation.
My ceiling temp in the bathroom the other day was 92f I found an old sun shade that aluminum covered bubble wrap stuff.
I placed it over the insulation to create a Radiant barrier.. the next day was even sunnier and hotter and the ceiling temp was 82f .
Look up AttifFoil radiant barrier.
If you have windows that get sun think about Low E film.. Lowes sells it.. i put it on my geo metro Huge difference when i installed them in my home
