Garden roofs offer many benefits. Not only do garden roofs offer a beautiful appearance, garden roofs offer many environmental and economic benefits.

Environmental Benefits

  1. Improvement of air quality
    • Plants capture airborne pollutants.
    • Plants reduce carbon dioxide in the atmosphere and produce oxygen.
    • Plants filter toxic gases.
    • Garden roofs cool and moisten the air.
    • Plants help filter out dust and smog elements.
  1. Rainwater Benefits
    • Helps prevent the burden on sewer systems.
    • Rainwater is soaked up by the plants and then released into the atmosphere through transpiration and evaporation to help reduce rainwater that may overflow the sewer system.
    • Garden roofs reduce the amount of storm water runoff.
    • Garden roofs not only retain huge amounts of rainwater, they also purify the rainwater.
  1. Provide habitat for wildlife
    • Provide habitat for wildlife.

    • Provide a natural habitat for birds.
    • Provide a natural habitat for insects.
  1. Energy Conservation
    • Provide great thermal performance and roof insulation for the buildings.
    • Reduce air-conditioning costs.
    • Government incentives for garden roofs.
    • Reduces temperatures of the roof surface and the surrounding air.

Economic Benefits

  1. Reduces Restoration Costs
    • Garden roofs protect the waterproofing from UV exposure and damage. This increases the life expectancy of the waterproofing and results in reduced maintenance and replacement costs for your roof.
  2. Reduces Energy Costs
    • Garden roofs provide shade and also remove heat from the air through evapotranspiration reducing temperatures of the roof surface and the surrounding air.
    • Garden roofs also act as insulators for buildings by absorbing heat and keeping buildings cool inside.
  1. Increased Roofing Membrane Durability
    • Garden roofs decrease the exposure of waterproofing membranes to large temperature variations.
  1. Noise Reduction
    • Garden roofs have provide a decrease in noise.
  1. Property Value Increase
    • Garden roofs can increase a building's value.
    • Garden roofs are an incentive to those interested in the various benefits offered by garden roofs.
