This study reports structural characteristics of damaged houses and cause of roof damage due to Typhoon Faxai. The field survey was conducted in three areas of Chiba Prefecture. It was found that the damage rate in these areas was about 60%. Damage to houses equipped with roof tile was remarkable, whereas the rate of damaged houses decreased as the building age became younger. Younger houses tend to have slight damage to roof and its cause was often wind-born debris from neighbor with damage due to strong winds during typhoon.
