Many residential buildings in Ondo State and Akure in particular have experienced
incidences of roof failures in recent times, as a result of several factors among which are, the
effect of prevailing winds on roof, and more importantly varied roof slopes. Survey was
undertaken to investigate the pattern of failure, causative agents, consequences and possible
remedial measures aimed at curtailing these occurrences. Besides being blown off, which is
the popularly acknowledged index of failure. A number of roofs were found to have failed in
their primary function of offering protection against rain even when they were not blown off.
Wind is a major causative agent of roof failures as it either completely removes the roof or
tears it, leading to leakages.
The survey adopted the use of questionnaires, and interview schedules. Information
considered of relevance to the study was the type of roof, slope of roof, prevailing winds and
rainfall pattern in Akure. As panacea, the design of steeper slopes, adoption of a good
maintenance culture, good workmanship and consultation of experts in the selection and
construction of roofs are recommended.
