Definition

Construction

  • A term that most commonly refers to a roof covering employing flexible elastomeric plastic materials from 35 to 60 mils thick, that is applied from rolls and has vulcanized joints. The initial cost of an elastomeric-membrane roof covering system is higher than a built-up roof, but the life cycle cost is lower.
