Complete GRP Accreditation Package

  Enroll in Course

The Green Roof Professional (GRP) Training & Accreditation program was created in an effort to bridge the knowledge gap in industry training and best practice. Before this, no traditional discipline or training contained all of the competencies necessary for green roof success- from building science, horticulture, irrigation, waterproofing, plant physiology, structural engineering and beyond. Since then, over 750 individuals have successfully completed the GRP Accreditation Exam and earned the GRP designation.


This Complete GRP Training & Accreditation Package Includes:

  • Access to all three GRP Training courses
    • Green Roof Design & Installation
    • Green Roof Waterproofing & Drainage

This collection of courses allows trainees to access tools and techniques needed to meet green roof project objectives on schedule, to specification, and within budget, the latest industry developments, technical standards and research findings. This training program has supported the remarkable growth of the green roof industry in North America over the past ten years by serving as a comprehensive reference for individuals who design, install and maintain green roofs.
