Comprehensive Investigation into the Menace of Roof Collapse in Tamale and the Way Forward

Abstract

There is a perpetual problem of partial or complete roof collapse within

the Tamale Metropolis and other parts of Ghana. This has become an issue

of grave public concern since this menace affects both public buildings

of all kinds (schools, offices, churches, mosque etc.) as well as domestic

buildings.

This research sets out to conduct comprehensive investigations into the

nature of roof failures, causes, and effects and then propose remedial

actions towards stemming the tide.

The study employed the use of roof construction affirmation surveys,

questionnaires, interviews and focus group discussions. Relevant

information 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 belongings

and exposure to inclement weather conditions, the psychological trauma

victims are subjected and pressure on incomes and living conditions as a

result of the cost of repair or replacement of the roofs.

It is recommended that expert advice be sought in checking maintenance

requirements of existing roofs in the study area and also during the design

and construction of new roofs. Tree planting programmes for this heavily

deforested region should be encouraged. The use of green timber for roof

construction must be replaced with well-seasoned ones. Proper construction

detailing and placement openings buildings should be done so that wind

flow during a windstorm is optimized.
