Chart: Whole life cycle costs per m2 over a 60 year period taking average values for life cycle costs and maintenance factors for each of the roof options. Roof costs include for cost of a dry fixed roof covering and the cost of typical underlying supporting structure (e.g. roof trusses).
Product Costs: were primarily compiled using Davis Langdon’s extensive National Cost Database, Davis Langdon’s professional judgement and discussions with specialist contractors. Additional data has been obtained from the Building Cost Information Service (BCIS); SPON’s Architects and Builders’ Price Book 2004 and the Department of Trade and Industry (DTI).
