Reflective Roofs and Urban Heat Islands

Protecting people, the environment, and the economy

Webinar On Demand
Sponsored by Duro-Last®, Inc.

Presented by Dr. James Hoff

As buildings, roads, and parking lots replace open land and vegetation in and around cities, the resultant urban areas become significantly warmer, forming a “heat island” within the landscape. This webinar will discuss how urban heat islands pose a significant problem that may jeopardize the economy, the environment, public safety, and human health. The webinar also will review current approaches to address the consequences of heat islands, with an emphasis how reflective roofs offer the most feasible and cost-effective strategy. Finally, the webinar review important characteristics of reflective roofs to help the building designer optimize roof system design and selection in urban areas.

Dr. James Hoff is an experienced executive and consultant in the building materials industry, currently serving as president of TEGNOS Research, Inc. a consulting organization founded in 2007 and dedicated to expanding understanding of the building envelope.


Known as the “World’s Best Roof®,” a Duro-Last® roof is perfect for any flat, low-sloped, new or retrofit application. Precision-fabricated accessories combined with prefabricated deck sheets or roll goods allow for a watertight roof that doesn’t sacrifice aesthetics.
