The aim of this research is to analyzed and compare the life cycle cost
of alternative root covering materials, Zink coat roofing sheet
materials, corrugated Asbestos cement roofing materials, concrete decked
roof materials, and long span aluminum roofing materials were
considered in this research work with the objectives to determine the
initial cost and 4fecycle cost of each roofing materials, to establish
the relationship between the dfferent roof covering materials on the
basis of their lfe cycle cost implications. The need for this research
is to help the client on making decision on type of roofing material to
be used in building construction project on the basis of maintenance
cost economy as a whole. The composition of building construction cost
are made up of materials, labour, plant cost, and general overhead and
profit. The procedure for data collection was well structured
questionnaire administered to the personnel, of the various organisation
(Construction companies). Quantity Surveying Firms were visited to
obtained the cost data of those roof covering materials. The instrument
for data analyzing is the use of the present value formular of Ni for
the techniques of appraisal under initial rate and the cost in use of
alternative roof covering materials. The summary of finding revealed
that sink coat steel roof materials has the Initial cost of N69 75 which
can be maintained at N33. 613.92 and has overall cost of N52066.28.
Corrugated asbestos cement roof materials has the initial cost of N6975
which can be maintained at N33.613.92 and has overall cost of N11983.89.
Concrete decked roof materials has the Initial cost of N3862.50. it can
be maintained at N20, 107 and has overall cost of N28,318.29. Long span
aluminum roof materials has initial cost of N1812.50 which can be
maintained at N9435.33 and replace at N1778 and has overall cost of
N13025.83. From the table of the cost in use of the various roofing
materials shown in the work it is observed that the corrugated asbestos
roofing sheet material has the cheapest initial cost This is followed by
long span aluminum, concrete decked and zink cost roof in ascending
order. The cost in use information also revealed that the long span
aluminum roofing material has the lowest total cost. Cost in use and
this is followed by corrugated, asbestos cement roofing sheet, concrete
decked and Zink coat steel in order to magnitude. From this research, it
is recommended among other that the initial cost of roof covering
materials should not be the only reason for it selection.
