Half of the world’s population is said to still use earth to build their homes. Most homes in U.S have either wooden or metal framing for constructing walls. The new trend is now going green as most of the people are worried about the after effects of global warming. One should research enough about the green materials before purchasing and the government will be able to tell, if a product is green or not. Now people tend to prefer green roofing Chicago rather than roofing from non – organic products.

Some time before getting organic or natural materials was difficult for everyone. This is so because not everyone maybe aware of the rising environmental issues or may know where and how to obtain green materials. The roofing contractor’s may sell only normal composite shingles or asphalt composite shingles to their customers as it is the cheapest and the easiest. These products are guaranteed to more than 30 years.

There may be many people or products claiming it to be green. Many companies try to market their products using the eco – friendly label. Some critics say that the energy used up to harvest and plow organic materials like bamboo uses more energy than creating artificial or non - organic materials. The idea of going green is more controversial

The government will be able to tell if a product is 100 percent green or not. The U.S green Building Council (USGB) is an organization with large network. The organization’s main aim is to provide information and education regarding the green building to people.

They are present in almost every state in U.S. They have developed LEEDS (Leadership in Energy and Environmental Design), which are the nationally approved standards for green buildings. The LEED has a range of certifications like ordinary to platinum to which they award according to the benchmarks met by the building.

When one wants to roof ones house using green materials, one must look products that are natural, renewable or that is recycled. Recycled metal, fiber cement, clay or slate tiles, wood shake etc are few of the materials.

Few of the points to be remembered while purchasing green materials are:
1. The recycling ability of the product should be looked upon. It is good if it already is a recycled material.
2. Avoiding zinc and copper coated roofing materials may wash down into the water and can cause problems to the inhabitants of the water body.
3. One can make sure that it is durable and still made from non - toxic materials.
4. If one lives in a hot climate using light colors and high reflectivity for the roofing materials, is the best option to cool the inside temperature.

Some companies recover used and older timber to make the roofing and support structure of the buildings. Instead of cutting down new trees, using the old sturdy wood may make considerable efforts for controlling pollution.

There are many materials in which we can achieve a green building. One may even tend to buy green colored shingles or tiles, in order to go green, but it would not be original. True green is a possibility, which is called a living green. It is flat or low slope roof covered with grass or plants on top. They also consist of growing medium and waterproof membrane. They are a very expensive to maintain.

The advantages of a living roof are:
1. The vegetation on top absorbs the water and prevents water damage.
2. It makes a perfect insulation for the house.
3. It reduces the heat inside the house.

John Manville’s JMCleanBond fire resistant roofing membrane does not use solvent based adhesive or heat in installation. It is guaranteed with 100 percent weather protection. This is ideal for occupied building where installations could be done easy without worry.

All this would help to reduce the usage of air conditioners and then in return reduce the consumption of electricity. Helping to preserve the natural resources is the ideal thing to do. Depletion of natural resources with global warming causes innumerable problems to humans, animals and plants. Effort from one person would definitely reduce the damage to a large extent. Chicago roofing contractor’s and government officials are taking immense effort in anti – pollution and energy conversing matters.
