Green Roofing: Is It Always A Good Idea?
There has been a large push for green roofing over the last few years. As people become more environmentally conscious, they want to reflect their ability to do their part when making decisions for replacing materials around their home. With so many green home products available, it was of no surprise that roof materials followed suit and have been gaining interest ever since. Roofing contractors in San Antonio have been quick to pick this trend up.
Benefits Of Green Roofing
Green roofing refers to the use of environmentally friendly roof materials. Common roof materials now come in recycled varieties, solar options as well as a purely “green roof” material.
Recycled roof materials are great for keeping old roof materials out of the landfill, as well as the materials that are used to make the recycled roof shingles. Plastic bags and bottles, rubber, aluminum cans and cardboard are all common items that are thrown away each day that can be recycled into composite, wood, or metal roof materials.
Solar panels have become popular for many homeowners looking to reduce their dependence on traditional energy sources. Reducing the need for traditional energy sources also reduces the carbon emissions generated from the plants that produce that energy source.
Green roofs are composed of natural vegetation, which provide a low maintenance option for homeowners. In addition, a green roof helps recycle the carbon dioxide into oxygen and offers urban areas a much need green living space.
Green Roofing Downfalls
There are no disadvantages to green roofing per say, except the added cost for the materials such as solar panels. Typically, recycled roof materials do not cost that much more than non-recycled roof materials. The biggest problem in green roofing is simply that it isn’t always possible or appropriate for a particular home.
For example, homes in climates where sunshine is limited will have a difficult time benefiting from the use of solar panels. Solar panels require a specific amount of sun in order to produce enough electricity to be beneficial to the homeowner. Climates in cloudy, rainy or seasonally low sunlight would not be appropriate for solar panels.
Instead of recycled roof materials, some homeowners choose traditional materials that are very light or white in color. This helps with the reflectioness of the sun’s UV rays. However, very light or white roof shingles are only effective in reflecting the UV rays if the slope of the roof is low. In other words, the roof would have very shallow valleys and less than a 15 degree slope. If a home has a greater than 15 degree slope, the sun’s rays will be reflected less towards the sky and more horizontally, towards the ground or into the eyes of people on the ground.
So green roofing is great option for those whom it will benefit, but it is not for every home. You can get more information at http://independenceroofingsa.com
