If anyone understands long-term life cycles, it’s a cemetery owner. I know one in St. Louis, MO, who owns two large, old mausoleums that stand side by side. One mausoleum has steel and copper roof systems that have remained relatively maintenance- and repair-free—and beautiful—for as long as 80 years. The other mausoleum has a flat-roof addition, built in 1986, which has a conventional roofing system that has been plagued by leaks for decades.
After determining the life-cycle costing and return on investment on the two roofs, it’s not surprising that the owner decided to retrofit the flat-roof addition with a metal roof. He anticipates far fewer worries with a metal roof, given its ability to shed rainwater and its 40- to 60-year service life.
In addition to its longevity and durability, metal retrofit also offers long-term cost-savings in the form of appreciable value of the building, better insurance rates, and energy-efficiency. Adding insulation to a metal retrofit can provide R30 thermal resistance—one reason why you increasingly see them on military and municipal buildings, including schools. Many building owners choose to add renewable solar energy technologies to these roofs, such as photovoltaics or solar hot-water systems, which can reap huge tax benefits.
For designers and architects, metal retrofits add generous curb appeal to buildings. Architectural metal roofs are meant to be seen, and a stunning sloped metal retrofit is seen far and wide—and well into the future.
