Green Roof Framing (GRHC) Green roof structures demand precision across three critical domains load-bearing calculations for substrate depths exceeding 12 inches, waterproofing layer integration with root barriers, and drainage system design preventing saturation. GRHC assessments focus intensely on these interconnected components, requiring candidates to solve real-world problems where substrate composition directly influences structural requirements and long-term performance.
