Centuries before, in many Asian countries bamboo, coconut tree leaves and the bark of certain trees was used. The bamboo was used for the structure of the building and the outer layer. The bamboo stems are split and turned alternatively and placed on the top. The thick bark of certain trees are peeled off and placed on the roof in some places. Even now people living in developing and under developed countries often build a roof above their heads, with simple organic or bio – based materials.
The new roofing materials, which also include synthetic materials, may be of good to the consumers, in the angle of protection and durability, but it may cause environmental hazards. The governments as well as the business professionals are coming out with the green initiation. The world now is completely aware of the seriousness of increased pollution and global warming and hence the demand for organic roofing is also on the rise.
The building and construction authorities in Chicago want to have a greener way to continue their business. On June 6th 2001, a new energy code – Amendment of Title 18 f Municipal Code of Chicago Concerning Energy Efficient Requirements, was passed.
Some of the features included in the new code are:
New requirements for roof, ceiling and wall insulation.
The building plan must be certified by a registered energy professional.
Insulation requirements must be approved by CRCA (Chicago Roofing Contractors Association) and NRCA.
An innovative biological product called the Clean and Green Roofing Solution has been developed by Johns Manville, a Berkshire Hathaway company and Green products LLC. Clean and Green roofing Solution is a white sealant derived from soya bean.
Chicago based U.S Equities Realty, a facility management company wanted a replacement for it’s worn out traditional black asphalt – covered rooftop. After much research they decided on the Clean and Green Roofing solution, an organic rooftop. This new roofing material is surprisingly non – toxic, flame resistant, water – proofed and has high reflectivity. The specialty is that it is able to lower the inside and the outside temperature of the building.
The cooler the temperature less would be the demand on the air conditioners. This in turn reduces the usage of electricity, and there by saving the resources.
Johns Manville’s JMCleanBond roofing system is also combined with Environmental Liquid membrane System (ELMS) of Green Products LLC to a single roofing system with the benefits of both the materials. John Manville’s JMCleanBond SBS fire resistant roofing membrane does not need any kind of heat or solvent based adhesives for installation, which makes it a non energy consuming substance.
Environmental Liquid membrane System (ELMS) is a USDA certified biological soy polymer membrane. It is completely water proof so it could be used in areas of buildings where there may be pooling of water.
The first roofing contractors association which was in Chicago dates back to 1870’s. The great Chicago fire in 1871 caused disastrous effect to people and their homes. After the fire, there were huge demand for re – constructing roofs for houses and other business enterprises and weren’t many genuine experts who could build roofs within short periods.
M.W Powell initiated other experts to join together and help re – build the roofs. M.W Powell and other experts pooled all the resources such as man power, equipment and materials and met the high demand of roofing for the people of Chicago. After this incident, the need and importance for strong and professional roofers was understood. This formed the building blocks of today’s Roofing contractors association all over the Unites States.
Some of the features of Chicago Roofing Contractors association are:
Imposing standard in the quality.
Develop new and strong roofing systems.
Elimination of contractor’s who come below the stipulated standard.
Training and Education of Roofing employees.
