      Sustainable Roofing System

      Over time, and with many technological developments, as well as with the rising concern for the environment, the role of roofs has changed significantly. It is not just about having a roof over your head. They have become a much more complex issue. They are not just roofs anymore, they have become roofing systems. With the attention increasingly shifting towards the environment, conservation of energy, and energy efficiency, one of the most important characteristic of a roofing system is to be sustainable.

      A sustainable roof protects your house from leaks and moisture, prevents energy loss, lasts for many years and is recyclable. Sustainability, however, is a complex issue and no easy task take on. There is not one, simple characteristic to make your roof sustainable.

      According to Georgia Roof Pro, a locally owned Lawrenceville, GA roofing company, aspects to take into consideration when it comes to sustainable features of a roof are the following:

      Service life

      First of all, you should consider roofs that are high rated. This means roofs that have a longer warrantee, a longer service life. They will save you money and are better for the environment, because less material will be used during their service life which also means less waste is produced. Roofs that are rated to last 50 years require the same amount of energy to be made as those rated to last 15 years. For example metal or slate roofs can easily last 100 years. They may be more expensive but are more economic in the long run and can be recycled.

      Insulation

      It is important to insulate your home in order to create a healthy environment and reduce the use of heaters and air conditioning. Much like with the walls, if the roof is properly installed and insulated, the energy required to cool or heat the interior is reduced. This means that great amounts of energy could potentially be conserved.

      Recycled materials

      Recycled roofing materials are always a good choice for you and the environment. There are hundreds of roofing materials that are available with 50% or more recycled content. These products usually also have long warrantees that can last up to 75 years. The important thing is that they can again be recycled in the end, in order to reduce the waste and pollution they can generate.

      Cool metal roofs

      Cool metal roofs have some of the longest warrantees, are very easily recycled. They are the lightest, most enduring roof materials.  They are completely non-combustible and, therefore, one of the safest exterior features you can put on a building or a house. They also reduce the roof weight and their maintenance is reduced to an absolute minimum, bringing them as close to a permanent roof solution as possible. They are designed to reflect more sunlight and absorb less heat than a standard roof. While saving energy, cool roofs also help reduce the heat island effect in urban areas, which in turn reduces air pollution.

      Solar/photovoltaic system

      Solar roofing system can be a pollution-free producer of electricity for your home, and at the same time a cost-effective power supply. This system includes solar or photovoltaic (PV) panels. They use solar cells to convert the sunlight directly into electricity. The performance of a solar cell is measured in terms of its efficiency at turning sunlight into electricity. This system is energy-efficient, as well as cost-effective – it reduces your utility bills and energy consumption.

      Green roofs

      Green roofs are another way to go. They are roofs with vegetation, rooftop gardens. They are partially or completely covered with plants and other vegetation. These roofs can absorb rainwater and prevent runoff, provide insulation for your home, and also reduce the heat island effect in urban environments.

      Roofing systems are becoming more complex as they become more sustainable and energy efficient. New characteristics are being added and new technologies developed daily, but it is only with the end goal of preserving our environment, fighting the global warming, and reducing the waste and pollution we create.
