Synopsis of Presentation:

Once thought to be a “burden” for roofing system, overburden benefits are increasingly emerging as a roofing advancement that’s here to stay. This presentation explains why selection of the overburden system is only part of the design; selection and design of the roof membrane is critical for a long-lasting performance.

  2. Differentiate between various overburden options such as vegetative roofs, blue roofs, blue-green roofs, and purple roofs.
  3. Understand roofing considerations for rooftop overburden systems including solar PV arrays.
  4. Recognize how selection and design of the roof assembly is critical for a long-lasting overburden installation.
  5. Review roof assembly design considerations including membrane thickness and color, roof attachment method, presence of a cover board, the importance of continuous control layers, and roof details and flashings.
