Each day as the sun comes up it beats radiates down onto a buildings roof, the tin or tiles begin to absorb this radiated energy and heat up.

As the hot roof radiates heat into the ceiling cavity, all other elements, like the air within the loft and the plasterboard ceiling between the loft cavity and living spaces begin to absorb this heat energy. Eventually the plasterboard ceiling heats up and conducts heat from the attic and begins to radiate that heat into the living space and so the living space heats up.
