Residential roofing presents homeowners with a choice between two popular materials: metal and asphalt shingles. Deciding between the two can be a tough decision due to their unique advantages. Metal roofs are known for their durability and eco-friendliness, while asphalt shingles are valued for their affordability and ease of installation.
When it comes to energy efficiency, both metal roofs and asphalt shingles offer benefits, but one may suit your needs better than the other. At New Roofs Group, we understand the importance of energy-efficient solutions, and we've put together this guide to help you make an informed decision about your roofing material.
Which Roofing Type Offers Better Energy Efficiency?
Metal roofing systems and asphalt shingles differ significantly in their energy-saving capabilities. Metal roofs excel in energy efficiency by reflecting heat away from your home, while asphalt shingles incorporate special granules to reduce heat absorption and transfer.
Here are the reasons why metal roofs are often considered more energy-efficient than asphalt shingles:
Low Thermal Mass: Metal roofs have low thermal mass, meaning they absorb, store, and release less heat compared to asphalt shingles. This feature is crucial because excessive heat absorption or dissipation can strain your HVAC system, leading to increased energy consumption and higher utility bills. Metal roofs help maintain comfortable indoor temperatures without overworking your cooling system.
On the other hand, asphalt shingles have higher thermal mass, which can result in heat retention and slower cooling times. This can create heat pockets near your roof, making it harder for your home to cool down efficiently.
Superior Reflective Properties: Metal roofs boast high solar reflectance, with materials like steel and aluminum reflecting up to 60% of solar energy. This reflective ability helps keep your home cooler by reducing heat absorption. Additionally, cool roof coatings can further enhance a metal roof's solar reflectivity, leading to greater energy savings.
In contrast, asphalt shingles have lower reflectivity, especially darker-colored ones, which can contribute to heat absorption and higher indoor temperatures.
