Abstract
A roof construction method using expanded metal lath laid on top of corrugated metal roof deck for the purpose of creating ventilation ducts in the valleys of the corrugated metal deck. The ventilation ducts created are vented to the building space below through vent slots in the valleys of the metal roof deck. A concrete slab with finished rubber roof poured in top of this roof deck with ventilation ducts will have enhanced ability to release moisture trapped from the concrete curing process.
