Which Roof is the Greenest?


Building owners recognize that their roof has environmental and energy impacts but it isn’t easy to quantify those impacts and costs. This webinar will focus on how to assess various factors – including insulation, roof surface, thermal performance, and service life – so that owners can evaluate the green impact of different roofing systems over their lifecycle in any given climate zone.

Learning Objectives:

  • Recognize principles and guidelines for rating the green performance of roofing systems.
  • Understand the relationship between roofing and energy usage.
  • Understand roofing’s lifecycle impacts on the environment.
  • Understand options for rooftop energy production.
