You don't have to take the roof off to insulate above it.
Polystyrene is waterproof, wind proof and its not effected by ice.
You can lay sheets of polystyrene on the roof, cover them with waterproof plywood and then a layer of small stones about three inches thick. The stones will protect the plywood from blowing away and being killed by the sun.
As you can walk on polystyrene floor grade you can also cover it with Firestone rubber, a one piece made to measure waterproof roof.
Polystyrene will remove the direct contact between the sun and the inside of your home making it a lot cooler. Any thickness will help, but eight inches will do the best.
