TIPS ON ROOFING CONCRETE ROOF DECKS.

If properly designed and constructed, almost any roofing system will work on a concrete roof deck. But because not all concrete roofs are the same, determining which roofing system will perform best requires the answers to many questions: How long must the roof last? Must it endure constant sun or severe winters? Must it withstand high winds? Is there usually a lot of traffic on the roof? Is the concrete roof deck dead level or sloped? Is it precast or cast in place? A complete roofing system for a low-slope roof consists of a vapor retarder (if required), insulation (if desired), and a roof membrane and flashing system. This paper summarizes numerous combinations of roofing materials and installation methods.
