Metal roofs are rarely mentioned where environmentally roofing materials are being discussed, but they aren't that damaging to the environment. Metal may not occupy the top spot for the most eco-friendly roofing material, but these four reasons mean the material isn't that dangerous to the environment:
The Material Is Recyclable
Most metal roofs are made from recycled materials. The percentage of recycled materials usually ranges from 25% to as much as 98%; the level of recycled content depends on the manufacturer. At the same time, when you eventually replace your metal roof, the old one will be a hundred percent recyclable. This means metal rarely fills landfills.
You Can Install It Over An Existing Roof
Roof replacement can be damaging to the environment if most of the old materials are taken to a landfill. However, this doesn't need to be the case if the new roof is a metallic one. Metal roofing isn't very heavy, and most building codes allow at least two layers of roofing. Thus, instead of tearing up your asphalt roof and taking it to a landfill, you can just cover it with the metal.
It Is Durable
As discussed above, replacing a roof harms the environment if most of the old materials are taken to a landfill. The more durable your roofing material is, the longer it will take before replacing it. This means that a durable roofing material is often more environmentally friendly than a less durable one. The metal may not be the most durable roofing material known to man, but it compares favorably with many popular roofing options. For example, a metal roof can last for between 50 and 100 years depending on the type of metal, whereas asphalt roofs rarely pass the 30-year mark.
It Has Energy-Related Benefits
Metal roofing can reduce your energy consumption in several ways. For example, a reflective metal roof can reflect as much as 80% of the solar energy that falls on it. This is energy that would have raised your room temperature, requiring hard work from the air conditioner (hence energy consumption) to get rid of. You can also retrofit your metal roof with a solar thermal heat recovery system that harnesses the roof's heat to warm up your rooms or heat your water, which reduces your overall energy consumption.
In short, don't dismiss metal roofing products if you are in the market for a roofing material that isn't too harsh on the environment. For more information, contact Chinook Roofing or a similar company.Share
