1.0 Introduction
1.1 Background of the Study
According to Barry (1996) Roofing materials are materials which provide thermal insulation, reduces noise provide surface for decoration diffuse light covers services pipe work used for conduct electrical wiring and also provide surface insulation from of electrical fittings, such as lamps fan alarm etc. Various materials are used for the construction of roofing materials nation world wide, for the purpose of this research life cycle cost implication of using alternative roofing materials. Materials are said to be substances from which something else can be made, the implication of using any material in construction of roofmg material is very important of cost is being considered. Apart from economical (cost) point of view there are several other factors which comple to choose a particular type of roofing material, these include aesthetic durability, low maintenance cost, thermal insulation etc.
Recently advancement in technology which lead to growth of modern construction material has also compelled people into try to blend with technological advancement in roofing materials without conceding the cost implication of such materials. It has also increase in the industrial advancement in roofing materials and the need to give a client real value for his money which promotes the quantity surveyors into comparing the cost implication of using different types of roofing materials from the economic point of view. Cost implication of different types of roofing materials from the economic point of view simple mean the consequences of using an alternative roofing materials for producing a roof. The types of roof to be compared are in corrugated Abestos cement roofing sheet, concrete decked roof, long span aluminum roofing sheet and zinc coating steel root sheet. They all offer to a building the same function, they only differ in strength cost of construction, method of fixing and maintenance cost The result of this research will aid in making decisions on the type of roofing materials to choose for a construction of a project.
1.2 Statement of the Problem
Research has it that there has being a steady increase in the cost implication of using alternative roofing materials. The research pose the following problems. What is the relationship that exist between the various alternative materials for roofing on the basis of their life cycle cost?
1.3 Aims of the Study
The aim of this research is carry out a comparative study of a life cycle cost implication of using an alternative roofing materials.
Objectives
- To establish the initial cost of the alternative roof covering
- To establish life cycle cost of various roof materials.
- To compare the initial and the lifecycle cost of the alternative roof covering material
1.4 The Need for the Research
The result of these research will help the client in making a decision on the type of roofing materials to be used in construction of any further project having consider their economic factors durability maintenance cost and aesthetic.
1.5 Scope of Study
The scope of this project work is based on the selected roofmg materials which include corrugated Asbestos cement roofing sheet, concrete decked roof, long span aluminum roofing sheet coverings and zinc coating steel roofing sheet.
1.6 Assumption of Study
While carryout this research, it was assumed that the total area covered does not affect the cost of the roofing materials. All economic factors capable of influencing the cost of roofing materials are kept at constant. Expected life of a building is 60 years.
