Also called vegetated roofs, eco-roofs, or garden roofs, a green roof is simply a planted area on a flat or sloped roof. You can grow everything from low grasses, herbs and sedums to trees and shrubs, depending on the type of green roof.
Green Roofs Offer Many Benefits to Your Project
- Visually more appealing and provides a park-like ambiance on your rooftop
- Can contribute to your sustainable building certification rating
- Slows down storm water flow by retaining up to 75% of rainwater, thus alleviating the pressure on storm water and drainage infrastructure
- Reduces the urban heat island effect
- Improves air quality with increased green space which filters air
- Reduces building’s cooling energy consumption and costs particularly in warmer months due to thermal mass effect of the green roof
- Extends lifespan of the waterproofing membrane by protecting it from damaging UV rays and freeze-thaw cycles
- Increases your property value by providing a valuable building asset
