Synopsis

Roofing assemblies are the first line of defense against the elements in the complete building envelope. Roofing assemblies must be able to protect a structure from the natural hazards associated with the local environment, including rain, hail, snow, high winds, temperature extremes—and even fire.
When it comes to many modern commercial roof structures, bigger is better. Warehouses, distribution centers, warehouse stores and other large commercial facilities typically have roofs that measure in the hundreds of thousands of square feet. As commercial facilities have increased in size over the past few decades, so too have the challenges in property loss prevention.

The failure of a building’s roof can have a devastating impact from which a business may not be able to recover. When a roof is damaged or destroyed, the building contents can be exposed to moisture and contamination, further compounding the loss.

This presentation will focus on some key areas as they pertain to roofing. Common types of roofing systems and potential risk associated with roofing systems will be reviewed. An in-depth explanation testing and evaluating roofing systems including wind dynamics and wind load requirements on roofing “system” to testing as opposed to a “product-based” approach is discussed. Brief comparisons to some major international building codes and requirements will also be covered. "
