Ventilation method in ventilated 30° pitched-roofs are examined to prevent icicle and ice dams forming on the inclined roof of insulated and airtight house. Simulation code that can be approximated measurement temperatures of the experimental house were developed, and was analyzed temperature of ventilating roofs with different insulation thickness and different ventilation method, under the several house location. From the simulation results, the effectiveness of the ridge opening is obvious, and the high insulation thickness can reduce ventilation rate. It also made clear that the ventilation rate of ventilating attic space is rather small for preventing icing at eaves, it especially means normalized opening at eaves or ridge on top should be made bigger anyhow from the architectural point of view.
