ABSTRACT

Roofing decisions are important not only because a new roof is a costly investment but also because a sound roof is vital to the longevity and livability of a home. There are few decision making approaches available for the selection of a proper roofing system that is not only cost effective but also has a reasonable life. This study intends to address the problem so that homeowners, builders, architects and other stakeholders of residential construction sector can make informed decisions on which type of roofing may be best for their situation. This study evaluates common types of “steep” sloping residential roofing systems in South Florida using a life cycle cost analysis (LCCA) approach. The study first establishes the expected service lives of various steep-slope roof systems by considering roofing longevity based on actual replacement records and surveys. Pertinent cost data needed for applying life cycle cost concepts to roofing decisions has been collected. The results reveal that although, all the considered roofing system options available in Florida are quite economical, but the Standing Seam Galvalume® Roofing is the best option having per square feet cost of $1.07 and life expectancy of 34 years.
