Targeted Canopy Coverage Program  (TCCP)

Our Targeted Canopy Coverage Program (TCCP) uses adaptive maintenance protocols, based on our unique combination of first-hand experience, lab-generated data, and scientific resources. We apply these protocols from a long-term perspective, with the goal of reinforcing the self-correcting trends of nature.

We keep our green roofs looking fresh during the growing season (March - November), visiting once every 45 days to ensure peak aesthetics and performance. We achieve this through the following strategies:

Lab-Testing and Expert Analysis

  • Checks the "pulse" of the green roof

  • Allows precisely timed and calibrated soil adjustments

Optimize Soil to Promote Healthy Growth

  • Allows proper establishment and plant fortification

  • Healthy plants suppress weeds and endure stress 

Monitor Moisture Balance to Keep Plants Happy

  • Ensure drainage is sufficient to prevent oversaturation and excessive weed growth

  • Ensure retention is sufficient to allow plants to thrive

Manage Weed Pressure

  • Unwanted species removed each visit

  • Clean roof and sharp lines, year-round

 Perform Thorough Inspections

  • Inspect for underperforming plants and underlying causes

  • Concerns included in visit reports, providing multi-faceted solutions

 Adjust to Seasonal Challenges

  • Monitor and optimize plant dormancy cycle

  • Install emergency irrigation in times of extended drought

  • Utilize weather data to enhance plant performance


Green Roof Visit Reports

Reports are provided after each visit so you have peace of mind that the roof is being looked after properly. Each visit, we perform inspections of the vegetative surface, green roof media (soil), and the observable roof membrane to identify any potential problems that may arise over time. The reports include information on…

Plant Coverage

  • Estimated percentage of desired coverage vs. bare areas and invasive species

Plant Media Inspection

  • Inspect for unhealthy or under performing foliage, bare areas, etc. and identify underlying causes

Soil Media Inspection

  • Inspect for evidence of pests and diseases in the soil

Drain Inspection

  • Inspect all related drains for functionality

Weed pressure

  • How much weeding was done and how the weeds are affecting the roof

Observable Concerns

  • Bring attention to any site-specific issues we are concerned with or are already addressing, with a solution-based timeline 

Plan of Action

  • Provide next visit date and protocols expected to be performed

Photos of Interesting Areas 

  • Attach before & after photos of our work each visit, along with anything unique we observed, seasonal timeline provided at the end of the year
