The Most Energy-Efficient Roofing Materials
The rising dangers of climate change mean we can no longer ignore the choices we make that will affect our planet's climate. It's more important than ever to recycle, reuse, choose energy-efficient materials, and promote energy-efficient practices. This applies to a lot of different areas in our lives, but one area is often overlooked: the roof of your home or business. Choosing an energy-efficient roofing material can drastically reduce the amount of energy expended in heating and cooling your building. Here are the most commonly used energy-efficient roofing materials available today.
The very best material for an energy-efficient roof in a warm and dry climate is metal roofing. That might seem counterintuitive. After all, metal heats up in the sun, right? Actually, metal roofing made of aluminum, steel, or copper is a perfect energy-efficient material. Because it's thin and reflective, it actually reflects heat back into the air rather than absorbing it. If properly vented, it means that less of the heat is making it into the building, requiring less cooling to keep the inside at a comfortable temperature in the summer. Another great characteristic of metal is that it's the perfect base for other energy-efficient options like reflective coatings, solar panels, or green roofs (roofs prepared with soil and plants that help insulate).
Another great energy-efficient roofing option is clay tile. In warm and dry climates, roofing tiles made of clay help capture warm air during the winter months and block it out in the hot summer months. They are also naturally reflective, which bounces a lot of the sun's heat back into the atmosphere. In fact, studies performed by the Florida Solar Energy Center have shown that tile roofing systems can reduce ceiling heat flux by as much as 40%.
Concrete and Slate Tile
Because extreme weather conditions like sleet, hail, and snow can degrade clay tile, concrete and slate roofing tiles are better energy-efficient options for colder climates. Concrete and slate tiles have similar energy-efficient properties to clay, but while clay tiles are quite reflective naturally, concrete and slate tend to absorb more sunlight, which can be better in the winter months. However, these materials can also be treated with reflective coatings to enhance their energy-efficient properties. One thing to note about concrete and slate is that they are both heavy roofing options and that means they can only be installed on a roof with proper support and underlayment.
