Green roofs have become an increasingly popular roofing solution for many home and business owners across the world. Whilst the green roofing concept has been used in Scandinavia for centuries, green roofs in their modern form were brought to the fore in Germany in the 1960s.
What is a green roof?
The term green roof is used to describe a roof which has been covered with grass or vegetation and placed atop a waterproof roofing membrane. Green roofs come in a variety forms, including full grass roofing systems or those which make use of other planted materials.
Depending upon your maintenance requirements and space limitations, there are 3 main types of green roof.
1) Intensive build up roofs: these are high maintenance roofs which essentially replicate a ground level garden and may include paving and decking.
2) Bio-diverse roofs: these require no maintenance and recreate a pre-existing ground ecosystem.
3) Extensive roofs: these require low maintenance and utilise low growing plants.
The desire for a green roof can be driven by a variety of factors, including the need for ecological and financial benefits, creation of additional outdoor space or a more aesthetically pleasing building appearance etc.
What are the benefits of green or grass roofs?
Ideal for urban environments where green space is lacking, green or grass roofs bring about many benefits to homeowners and business owners alike; including a selection of environmental and financial advantages as described below:
Environmental & Ecological Benefits
- Helps to facilitate the removal of CO2 and other harmful pollutants from the atmosphere
- Minimises the heat island effect by helping to absorb radiation from the sun, leading to decreased temperatures within urban dwellings.
- Improves building insulation and overall levels of energy efficiency.
- Helps to absorb rain water and improve water quality
- Provides wildlife with an ideal environment in which to inhabit.
- Helps facilitate a ‘grow your own’ culture with regards to fruits and vegetables
- Lowers costs due to improved energy efficiency in both cold and warm weather – improved insulation leads to lower heating costs in cold weather and heat absorption decreases temperatures in warmer weather.
- Increases property value due to the desirability and overall benefits of a green roofing solution
- Improves roof lifespan meaning replacement costs are minimised
Other Benefits Of Green Roofing
- Helps to improve the visual landscape, especially when used on buildings placed within a rural area.
- Increases sound proofing due to the use of multiple layers which help to absorb, reflect or deflect sound waves. This can lead to increased workforce productivity due to better workplace conditions.
- Increases the amount of outdoor space, especially ideal for properties without gardens such as those within urban environments.
Whilst the initial installation costs may be higher than those of a traditional non-green flat roofing system, the long term cost savings coupled with the numerous benefits make green roofs an attractive option well worth considering.
