As a result the roof structure can require less maintenance saving the owner money in replacement costs over the long term life of the roofing system.
The plants create natural insulation which means that there is less need to rely on heating and cooling systems to moderate interior temperatures.
But in fact both systems can benefit each other too.
The temperature on the green roof on the hottest summer days can be as much as 59 degrees cooler than conventional roofs on neighboring buildings.
A green roof can increase the life expectancy of a roofing system by protecting the roofing materials from direct ultra violet radiation and extreme temperatures.
This can lead an increase air conditioning and therefore increased energy use.
This is particularly relevant if a building has poor insulation and poor ventilation.
