Green Roofs and Green Walls


Portland is one of leaders in numbers of green roofs and Pacific Landscape Management has developed expertise in installing and maintaining this new technology.

Green Roof

Green Roofs have many benefits:

  • Reduces Stormwater discharge by 70-90% during the summer and 20-40% during the winter.
  • Reduces heating and cooling expenses by up to 25%.
  • Extends roof life by more than double.
  • Reduces urban “Heat Island” cooling our city during the hot summers.
  • 20 sq ft of Green Roof produces enough oxygen for one person.
  • Portland offers financial incentives for green roof installation.


Although Green Roofs have many benefits, they do require monitoring and maintenance. Due to our dry summers, irrigation is required for establishment and ongoing to maintain a roofs health. As with many other landscape elements, maintenance is necessary to ensure the desired plant palate survives. Many of the Green Roofs that we have seen have failed due to the lack of understanding of these maintenance needs. Few companies have the experience and expertise with Green Roofs that we have, and many other landscaping companies are not capable in maintaining them correctly.

Green Wall

Corey Peterson, our Sustainability Coordinator, participated in Green Roof research at Oregon State University and is certified as a Liveroof™ installer. He is experienced in all aspects of Green Roof installation, maintenance and renovation. Pacific Landscape Management is the only company that has incorporated weather based irrigation into the management of green roofs. Whether Smart Controllers or Moisture Sensors, we have the expertise to ensure your Green Roof is irrigated properly, maintaining the roof’s health and conserving water.
