Flood risk management must rely on the best estimate of potential damages to make oriented decisions. Flood depth damage curves are the most used method of estimating direct property damage. Although widespread, this method involves high uncertainty, as limited factors are typically considered. This paper aims to identify and prioritize additional contributing factors to flood damage that should be considered in damage estimation to reduce uncertainty. Forty-five Canadian experts, including adjusters, engineers, estimators, and contractors, identified and prioritized 40 factors contributing to flood damage in residential buildings beyond the traditional inundation depth factor. Analysis reveals that municipalities play a significant role, as seven of the ten most important factors fall under their responsibility in collaboration with provincial authorities who establish overarching regulations and policies. Shared responsibility encompasses key factors such as the distance of a building from a water course as part of land use planning, obligatory compliance with new building codes, and the design and maintenance of critical infrastructure like sewer systems. Given these extensive responsibilities, Canadian municipalities have a crucial role in proactively reducing flood risk and mitigating the impact of flood events. Expert judgment on the prioritization of factors reinforces the need to integrate a broader range of physical vulnerability and exposure factors into flood risk estimation tools and should encourage municipalities to collect and optimize the use of these factors
