Interface: EPDM Roof System Performance an Update of Historical Maintenance Costs
One of the most important steps in roof design involves selecting the best roof system for specific building conditions and building owner needs. In order to make the optimum selection, the designer must evaluate the costs and benefits of the many options available. While initial costs of roofing systems can be calculated with reasonable accuracy, it is much more difficult to accurately calculate the longer term warranty service and maintenance costs for different roofing systems. In order to make the best decision, the designer needs statistically accurate and reliable information based on actual historical performance of roofing systems.
