Getting The Norwegian Look – Green Roofs

When investing in changes to your roof, it’s worth considering the many benefits of green roofs, and particular influences from Norway. A green roof can be added to most buildings, and can involve creating a waterproof membrane and a layer of greenery and vegetation that can have create a mini ecosystem, with environmental benefits for your area and property. Norwegian roofs represent a great example of green roofs in action, and can be explored in more depth below.

Some Benefits of Green Roof

  1. A green roof represents an alternative way to insulate a roof compared to traditional tiles and composite materials, and can also produce impressive aesthetic effects. In a green roof setup, a waterproof membrane is laid down, with a soil layer above it. Depending on the size of the roof, a range of vegetation, plants, and flowers can be added to a roof, which can then be maintained and developed to create elaborate landscaped gardens; these gardens can also release oxygen and insulate the building below.
  2. Green roofing has been an option for Norwegian or Scandinavian roofs for centuries; in parts of Norway, green roofs were created on buildings with birch barks and roof boards, and also included sod for maintaining the stability of structures. Birch barks particularly offered a water tight membrane, which is now substituted in modern green roofs with bitumen and plastic drainage for releasing water. However, the basic principle of a green roof as an eco-friendly solution remains the same.
  3. Scandinavian and Norwegian roofs have managed to remain popular despite modern roofing methods, and when properly maintained, can include everything from dense foliage to small trees. The Scandinavian Green Roof Association is one of the more notable examples of how far traditional Norwegian roofs are entrenched in the building culture of the region, while these roofs have more generally become popular in the rest of Europe and the United States.

How to Choose a Green Roof for Your Home

If you want a green roof for your home, you have a choice of intensive and extensive options. An intensive roof typically requires a soil depth level of about one foot, and is suitable for denser types of gardens where deep roots are being used. By contrast, an extensive roof can only require 2 to 5 inches of soil, and does not need as much maintenance. Some companies will offer pre-assembled or modular green roofs, which can be planted with perennials for growth all year round.

It’s worth consulting with a specialist roofing company to see which green roofs will work best for you; they can assess the size and shape of your roof, and can advise you as to whether you’d be better suited to an intensive or an extensive green roof. Intensive roofs can be better if you have plenty of space, and want to be able to plant a wide range of different types of vegetation. Extensive roofs are more common, though, and are a good idea if you want to start off with a relatively thin layer of vegetation.
