The metal roofing panels that cover most American buildings could be replaced with composite material, and they could cost less than $2,000, according to a study by the American Institute of Architects.
The cost could be cheaper than buying a new roofing system from a supplier, according the study.
It’s estimated that about $600,000 could be saved from building the panels.
The study looked at the cost of the panels on commercial buildings in the United States, and it concluded that a composite roofing material could save about $1,300 per roof, or about $2.50 per square foot.
That would save about 7 percent of the costs of building a new house, the study found.
The report came just days after the city of San Diego, California, announced a $2 million investment in the design of a $50 million system to replace its existing roof.
The city’s decision to purchase panels from two companies in California was made after a review by the U.S. Department of Housing and Urban Development’s Office of National Housing Policy.
The department is responsible for building housing for low-income residents.
