As the world becomes more educated on the importance of sustainability, more people are trying to implement the knowledge into everyday living by recycling, saving water and eco-friendly buildings. One of the most recent sustainable solutions in the construction industry is using cool metal roofing which is basically a roof designed to reflect and re-emit back sunlight and heat instead of absorbing it like other roofing materials.
How Cool Roofs are Made
Cool metal roofs are made from tin, aluminum, steel or copper and then covered with a highly reflective white paint, sheet covering or reflective shingles. A cool roof can stay around 55 degrees Fahrenheit during summer while ordinary roof goes as high as 150 degrees Fahrenheit reducing your energy bill by 40%. Companies like Wespol have been at the forefront of installing sustainable roofing solutions and insulation for commercial, industrial and residential buildings.
1. They Do Not Absorb Heat
Unlike other roofing materials, cool roofs reflect sunlight and re-emit the heat back into the atmosphere immediately instead of absorbing it. This means that even on the hottest day, the building under that roof will remain cool and there will be no need to use an air conditioner or other cooling gadgets. The coating used in the best cool roofing can reflect and re-emit up to 90% solar radiation away from your building.
2. Prevent Urban Heat Island Effect
Once the heat has been absorbed by the building and the roof, it has to be emitted slowly into the air overnight and this causes a heat island effect which means the entire area will feel hot and more power will be needed to cool. However, there is no heat absorbed by a building when you have cool roofing so the effect will be prevented.
3. Reduce Peak Energy Use
Peak electricity demand happens when a lot of buildings are used too much power to cool or heat and it causes power outages. Cool roofs can prevent pea energy use and preserve your backup generator.
Other Benefits of Cool Roofs
- Metal is very tough and durable so you will get unmatched longevity.
- Metal roofs can withstand the worst of Mother Nature.
- Metal roofs are fire-resistant and impervious to pests.
- Metal is highly sustainable because it can be recycled severally.
Metal roofing is a great cost-saving investment that will not only benefit your household but the environment as well. It is a green home product with Energy Star and LEED Ratings so you know the benefits are real.
