A properly built concrete roof deck is the best defense against most natural calamities: fire, rain, hail, snow, heat, and cold. It is strong, durable, fire-resistant, very impermeable, and compatible with most roofing systems. To obtain a good roof system for a concrete roof, consider these suggestions: use a good attachment method; consider a ballasted roof in low-wind areas; use an elastomeric membrane on precast roofs; choose compatible insulation; be sure flashing is correct; and inspect the roof after bad weather and at least once a year.
