Common Commercial andIndustrial Roofing Materials andTheir Costs

Each roofing material offers a different balance of upfront coss, durability, consultacy, and life expectancy. Below is a detaild overview of thee mest consun systems used in commercial and industrial settings, along with typical cost ranges per square foot (installard).

Built- Up Roofing (BUR)
