The study had the objective of analyzing the influence of seven types of roofs on thermal comfort in poultry-house, in the region of "Paraíba Agreste’. The systems were: asbestos tiles and clay tiles without forced ventilation, asbestos tiles and clay tiles with forced ventilation, asbestos tiles and clay tiles with artificial ventilation and fogging and asbestos tiles with forced ventilation, fogging and sprinkling on the roof. The evaluation was based on the results of air temperature (AT), relative humidity (RH), black globe temperature (BGT) and the radiation thermal charge (RTC), measured at different diurnal times during the summer. Influence of the roof types on the thermal comfort was observed. In all systems the comfort index evaluated varied during the day and that AT, BGT and RTC showed values higher than those considered optimum. The RH values were within the thermal comfort zone.
