Better Economics over the Long Haul
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.
A Duro-Last Cool Zone roofing system delivers excellent life-cycle economics. Key benefits include:
- 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.
