In the current study, an analytical model is proposed that describes the thermal behavior of a heat discharge system in roofs. To validate it, an experimental prototype is used which has been tested by exposure to the sun and the measured results compared with the predicted values from the analytical model proposed by the authors. Were found error variations between the data in the experimental test and the analytical model of 6.5 °C as a maximum for the aluminum plate (or heat storage) and of 4.6 °C as a maximum for the temperature on the surface of the glass. It is considered that the analytical model proposed can be applied to predict the behavior of a heat discharge system in roofs by defining the system dimensions for the environmental conditions of the location where it is to be used
