- 2. Green Roof Outfitters Green Roof Outfitters (GRO) is a manufacturer and supplier of a proprietary modular green roof system, with it’s headquarters based in Charleston, SC. GRO is able to offer the fully vegetated system or just the needed components in the U.S. and Canada, and currently offers the components internationally.
- 3. History & Facts New Concept? Green roofs have been around since ancient Babylon Germany – first to mandate green roofs and offer incentives to install them Chicago – first US city to implement a significant green roof initiative 5,537,240 square feet installed in North American cities in 2014 Internationally – many cities are now adding mandates and incentives for green roofs.
- 4. Green Roof Basics What is a Green Roof? Configuration of plants, soil, and drainage layers installed on the roof surface of a building. Green Roof Types Extensive – range from 2.5” to 5” in depth and are the most common because they are lighter systems and require the least amount of maintenance. Intensive – range from 6” to 60” in depth. A variety of plants can be used, including shrubs and even small trees, but it requires constant maintenance and the structural loads are significantly heavier.
- 5. Traditional Modular Traditional vs. Modular Traditional System A multi-layered system that must be installed by professionals Modular System An all-in-one system that can easily be installed by anyone
- 6. All-in-one solution with simple installation and maintenance. Flexibility – easily add, remove or rearrange modules at a later date. Quicker installation vs. traditional green roofs = reduced labor costs and a quicker return on investment. Fully Mature on delivery increasing the rate of survival. Simplicity – modules are placed directly on the rooftops and do not require additional work to the roof membrane. Self-Contained System including drainage, growing medium, and plants – No edging required. GROWVista Modular System Benefits

- 13. Economical Benefits Reduces Cooling Costs Extended Roof Longevity Improved Labor Efficiency Improves PV Solar Panel Efficiency Creates Added Property Value & Usable Space
- 14. Environmental Benefits Particulate matter and carbon sequestered per 1,000 square feet of green roof via storage & Photosynthesis… Green roofs reduce storm water runoff. Average annual storm water retained is… Compared to conventional roof surfaces, green roofs lower surface temperature by up to… Green roofs can provide compensatory habitat for rare and endangered species affected by land development (ie: bees, butterflies, etc)
- 15. Frequently Asked Questions Is this for new construction, and if not, do I need to install a new roof system? Our green roof modules can easily be installed on new and existing buildings and roofs. Is my building appropriate for a green roof? Most homes and buildings with low sloping roofs are good candidates. What do I need to know about my building before starting? You will need to know the slope/pitch of the roof (lower sloping roofs are preferred) The structural loading capacity of the roof (consult architect/engineer/builder) Is the existing roof waterproofed and in good condition What are the costs and ROI (return on investment) period? The costs and discounts vary depending on the project size and whether you get the fully vegetated system or just the individual components. Ballpark costs are $10/sf for the fully vegetated system or $2.25/sf for just the empty module & filter fabric. (The above pricing does not include delivery or installation). The ROI is calculated from conservative estimates of savings gained from both energy savings and from the extended life of the roof membrane. The ROI can be greatly influenced by: project size, energy usage, level of insulation in roof, single vs. multi-story building and the costs of the green roof materials/installation. We see typical ROI periods between 3 – 8 years. This does not even include the savings gained by the storm water retention qualities or the added real estate values of the green roof. Other things to consider: Do you plan on utilizing it for a gathering space (access, added safety & live-loads to consider) Is it going to be used for energy savings, aesthetics, storm water retention or a combination of these Do you want the standard mix of green roof plants or do you need custom plantings Do you need the fully vegetated system or just the empty modules & components to assemble Are you planning to install the modules yourself or have them installed by others
