Changes in regulations on attic and roof space ventilation in International Residential Code of the USA and National Building Code of Canada were thoroughly surveyed to investigate the recent changes in roof construction and development of building science regarding prevention of moisture related problems. Also, differences in attic and roof space ventilation regulations in both the USA and Canada and in Japan are discussed. Present Japanese regulation mostly has its ground in the USA house construction recommendation in 1950s’, and has not been updated for many years. Issues which should be reconsidered in its future updating are discussed.
