While some types of roofing may have lower initial costs, the true costs of a roofing system are measured over its total life cycle. These include maintenance and repair costs, energy savings, and tear-off and disposal costs. Clearly, economics is a very important criterion for building owners, and High-Performance Roofing systems must be economical if they are to become viable, real-world options.

• Reduced installation costs through custom factory prefabrication.
• Low maintenance and repair costs.
• Protection from interior damage costs through leak-proof performance.
• Elimination of extended warranty costs.
• Savings incurred through reduced energy consumption, and related rebates or incentives.

In 2004 – before the most recent energy price increases – a 20-year comparison was prepared with the help of independent Midwest roofing contractors. The objective was to compare the life-cycle costs of a High-Performance Roofing system – in this case, a prefabricated white PVC single-ply – with popular black EPDM and BUR systems for a fully-warranted, 50,000 square-foot re-roof in the Midwest. This hypothetical comparison clearly demonstrates the impact that an energy-efficient, High-Performance Roof can have over time.

20-Year Life Cycle Cost Considerations	Roof A (White Granulated Modified Roof)	Roof B (White Duro-Last PVC/CPA Single Ply)
Roof Size	25,000 Square Feet	25,000 Square Feet
Roof Product Cost	$70,000	$88,000
Installation (labor + overhead)	$60,000	$45,000
Tear-Off, Disposal Costs	$12,500	$0
Est. Maintenance Costs, 20 Years	$5,000	$1,500
Est. Repair Costs, 20 Years	$7,750	$0
Est. Energy Savings, 20 Years	$0	($84,000)
Est. Life Cycle Costs	$155,250	$50,500
