Advancements in building construction technology and the advent of foreign materials that came with Nigeria’s colonial and post-colonial periods led to the mass abandonment of traditional buildings for a “contemporary” option. The need to preserve the nation’s architectural heritage led to the establishment of the Museum of Traditional Architecture (MOTNA). Within the museum are life-size replicas of various traditional buildings across the country. Studies, observations, and documentaries reveal how the longevity and functionality of indigenous Nigerian buildings have been altered by weather elements such as precipitation and relative humidity. This study investigates the impact rainfall has on the conservation of traditional heritage buildings over time. Four buildings that together represent the bioclimatic zones in Nigeria were selected through purposeful sampling. Heritage buildings were investigated through the case study/observation method. The studies revealed that all heritage buildings were significantly affected by the effects of rainfall due to their design morphology and material usage. The investigation concluded that the conservation of Nigerian traditional heritage buildings can be unusually challenging. This is because most local building materials are susceptible to the effects of rainfall and require frequent replacement, which might be against conservation laws.
