Metal roofing can be one of the most cost-effective types of eco roofing for homeowners who are interested in eco-friendly, long-lasting, high-performance roof coverings—but not all metal roofing is created equal. Here's how you can maximize the benefits of your metal roof by making it even more eco-friendly.
1. Look for high post-consumer content
Although most metal roofing does have some recycled material in it, there are a couple of things that can make yours even better than average. For example, you can choose a material that has a much higher percentage of recycled content. Another option is having recycled content that fits the description of "post-consumer." This is what you'd typically think of as recycled material. It's already been in a product which was then turned in to a recycling center or program by the end user. Many manufacturers count scraps from the manufacturing process as "recycled content" as well. However, while using these scraps is, of course, better than wasting them, it's not exactly the same as supporting recycling programs by buying post-consumer-content materials.
2. Choose a highly reflective surface
While shiny metal roofing materials may look as reflective as a mirror, there are actually ways to make them reflect even more of the light and heat they encounter. The main way to do this is by using a cool roof coating designed to reflect not only visible light but also invisible thermal rays as well. This can help your roof keep your house even cooler in the summer.
3. Find a solar array fastening system
Some metal roofs can provide even bigger eco dividends because they're easier to attach solar panels to. This type of roof is called standing seam. The seams allow you to snap in special mounting brackets for solar panels. Not only does this provide an added incentive to go solar, but it also helps the roof last longer than it otherwise might with solar panels because there are fewer roof perforations this way. It also allows you to get the solar panels installed at less expense to yourself because the installation process is quicker and easier.
4. Add supplementary efficiency measures
If you make sure your roof has plenty of insulation, this will allow you to save even more money on heating and cooling. And, a thermal reflective barrier installed under the roof will make it more efficient as well. Of course, you can always add more passive cooling measures such as a shade tree—just be careful it's not a messy one and that you don't place it too close to the roof.
These additional measures will help you to modify either a planned metal roof system or an existing one to help it perform better and be better for the Earth. For help with any of these measures, contact a residential roofing service.
