Environmental Benefits


Urban-Heat-Island (UHI)  Best-Management-Practice (BMP)

Green roofs reduce the UHI effect by adding cooling green vegetated space in place of empty roof space that radiates heat.


Storm Water Runoff BMP

Green roofs can help significantly reduce storm water runoff.  During large storm events, the run-off from roofs, roads, and other impermeable surfaces can over burden a city’s storm water system. This leads to contaminated water entering oceans, rivers, lakes, and other water resources. Vegetated green roofs can help mitigate this problem by retaining storm water — keeping an average 56% of annual rainfall from running off roofs and detaining the rest — slowing it’s progression into the storm water system.  More green roofs = less run-off.


Produces Oxygen & Reduces Pollutants

A green roof will filter the air moving across it. A study has shown that 10.76 sf of a grass roof can remove .44 pounds of airborne particulates from the air every year. It would only take 2.5 GROVista-4 modules or 5 GROVista-2 modules to accomplish this task. Another study found that 16.15 sf of grass roof can produce enough oxygen to supply one human with their yearly oxygen intake requirement. This is the equivalent of 4 Green Roof Outfitters’ modules.

The modules also filter pollutants from atmospheric rainfall. If these great benefits can be had with just a few or our modules, think of the ramifications of having a whole roof full of GROVista vegetated green roof modules….or a whole city full of vegetated green roofs!


Habitat Creation

Green roofs promote biodiversity by creating habitat for birds, insects, and other species important to a healthy ecosystem.


Regional Materials

Green Roof Outfitters uses project specific regional materials whenever possible to produce all of our products.
