Tile roofing is widely known for its long life span and outstanding durability. It might surprise you to learn that tile roofs are also inherently energy-efficient thanks to their natural thermal resistance and above-sheathing ventilation. Read on as commercial and residential roof replacement pros Sully-Jones Roofing shares how these two features help make tile roofs energy-efficient by design.
How Energy-Efficient Roofs Work
Every home has an insulated enclosure known as the energy envelope, which consists of the exterior walls, windows, entry doors and the roof. With proper insulation, the energy envelope helps maintain consistent indoor temperatures by preventing heat transfer. With less heat gain during hot days and less heat loss during cold days, the HVAC system consumes less energy, resulting in energy savings without sacrificing comfort.
Solar heat is absorbed through the roof. It accounts for most of the heat gain that happens during the summer season. There are various means to minimize heat absorption: reflective roofing material known as “cool roofs,” typically used in single-ply commercial roofing, is by far the most popular route. Active roof ventilation using exhaust fans can also help cool the roof down.
Energy-Efficient by Design
Roofing tiles are made of thermal-resistant materials clay or concrete. This natural insulation doesn’t require additional insulation under the roofing material, which, when combined with standard attic insulation, can significantly reduce the heat that gets into the indoor living space. Unlike cool roofs, you don’t have to pay extra for these features.
But what makes tile roofs truly unique is its traditional design. Other roofing materials lay flat on the roof deck or sheathing, which allows more heat to transfer from the outer roofing material onto the roof deck. Tiles, on the other hand, have large cross-sectional areas that create a gap between each layer, but more importantly, between it and the sheathing. This allows additional ventilation that dramatically reduces heat that gets onto the roof deck. When installed on a properly-insulated energy envelope, tile roofs can, by design, help you save on your long-term energy costs.
