If the idea of a roof helping the environment sounds a little funny to you, you've probably never heard of the urban heat island effect. This is a process that takes place when a city starts to heat up local ecosystems, changing the habitats and potentially making them unlivable for the flora and fauna who originally lived there. But the urban heat island is not caused mainly by heating your house or combusting fuel in your car; the main source of this effect is the black surfaces of roads and roofs, which capture and hold the sun's energy throughout the day at unnatural levels. So if you could keep your roof from doing that, you'd be helping to mitigate your community's detrimental effect on nature. But there are other ways a roof can affect its surroundings, too. Here are three ways your metal roof can help save the earth.
1. Energy use
Unless you're already sourcing your energy from solar panels installed on your roof, you're probably using energy that has a detrimental effect on the environment in one way or another. If this is the case, using less energy can mitigate that effect as well as putting money back in your pocket. One way you can use less energy is by having a cool roof, which is easy to do if your roof is metal. All you have to do to optimize a (properly insulated) metal roof for cooling is coat it with a "cool roof coating." In addition to helping your roof deflect thermal rays from the sun, this can actually help your roof last longer by providing a watertight seal.
2. Urban heat island
The urban heat island effect mentioned above can also have a big impact on your environment. The effects are often seen in the local environment, making it a more immediate problem than the problem of using up energy that comes from non-renewable resources. But fortunately for you, having a cool roof can also help diminish your personal contribution to the urban heat island effect. This is because metal roofs don't store heat as well as asphalt shingling does, and if you have a cool roof, it can be sixty degrees cooler than a shingle roof even if it's in the sun.
3. Non-renewable resources
Non-renewable resources have been touched on already. But in addition to the energy use of your roofing material, using metal can also diminish the amount of natural resources used to make your roof itself. Asphalt shingles take a lot of energy and resources to make. Metal can also take energy to make, but it commonly includes some recycled content and you can even find metal roofing that's more than nine-tenths recycled. Metal roofing usually lasts over twice as long as asphalt (even the cheapest metal variety, a tin roof, can last up to 50 years, while asphalt roofs are expected to last 20), meaning that you'll need less than half the roof replacements you would with asphalt.
As you can see, there are a number of ways in which your roof can affect the environment, and metal roofing can have a much less detrimental impact than asphalt. Visit Advanced Seamless Gutter & Roofing Inc. for more information.Share

Hi there, I am Gus Fuller. I would like to share my experience with tile backsplash construction. A tile backsplash works wonderfully in the kitchen as it looks nice and cleans up beautifully. The tiniest of tiles are often used to create intricate designs that do not overwhelm the space. You can use large 12-inch tiles instead for an understated look. You may either perform the work yourself or have a general contractor complete the job. Personally, I will use this site to explore the materials, tools and techniques used in tile backsplash construction. I will explain all of the finer details of the installation process to help you decide if hiring a contractor is a sure bet. Thank you for coming by my site. Please visit again soon.
