Relevantinformation synthesized indicates that the roof type, construction materials,building type and environmental conditions are crucial causative factors.Major consequences of roof failures include damage to personal belongingsand exposure to inclement weather conditions, the psychological traumavictims are subjected and pressure on incomes and living conditions as aresult of the cost of repair or replacement of the roofs.It is recommended that expert advice be sought in checking maintenancerequirements of existing roofs in the study area and also during the designand construction of new roofs. Tree planting programmes for this heavilydeforested region should be encouraged. The use of green timber for roofconstruction must be replaced with well-seasoned ones.
