What is an extensive green roof? Extensive green roofs are lightweight roofs covered with low-maintenance vegetation, such as succulents like sedum, herbs and grasses that are specially adapted to the extreme weather conditions on roofs. The costs of installing and maintaining extensive green roofs are low and they are more durable than conventional roofs. Download here the list of plants for extensive green roofs. Advantages of an extensive green roof: Aesthetic value: green and cheerful appearance of the building, which improves the living environment. Reduction in sewer system loads: the green roof system slows down rainwater runoff during peak loads that occur at times of increasingly frequent downpours. Combatting the heat island effect: unlike concrete roofs, green roofs do not fully convert solar energy into heat, but into water vapour instead. This has a cooling effect on the surrounding area. Protection of the waterproofing membrane: the vegetation helps to counteract the harmful effect of sunlight and rain on the waterproofing membrane. This protects the waterproofing membrane and it increases its lifespan. Ambient noise reduction: the vegetation helps to muffle noise from the surrounding area.
