    In this study, we aimed to evaluate the snow load in order to make the construction cost of animal facilities lower in Snow zones.
According to the investigation, we concluded as follows;
  1) Snow sliding is more influenced by the contact angle than surface coarseness. Snow sliding easily takes place on roofs with high water shedding.
  2) When animal facilities are designed, the roof slope should be more than 3/10 if corrugated painted steel sheet or fiber reinforced plastic are used. In the case of using fluorine films or C seed membrane, the slope more than 2/10 is enough.
  3) The design snow load should be evaluated not only by water shedding characteristics of roofs but also by livestock housing systems such as stocking rates which may affect the roof surface temperature.
