Why metal roofing generally reflects and releases heat better than asphalt shingles. 

Many homeowners don’t realize the impact their roof has on the rest of their home. But from attic temperatures and indoor comfort to air conditioning bills and beyond, the roof on top of a structure plays a direct role in how the rest of the home functions. And in general, if you want the most comfort and efficiency, especially during heat waves, you’ll want to consider metal according to the article, “Are Metal Roofs Cooler Than Shingles” by Mountaintop Metal Roofing.  

Why choose metal? 

Traditional shingles tend to absorb and hold heat because they are made with asphalt and granules. That heat can continue radiating into the attic and living spaces well after peak sun exposure. Alternatively, metal roofing reflects more solar radiation away from the home instead of transferring it into the structure below. 

Not only does this reflection of heat make the home more comfortable, but it can also help the roof itself last longer. Hot climates can cause asphalt shingles to crack, curl and age prematurely. But because the metal roof reflects that heat/UV rays, it tends to withstand high heat better and have a longer lifespan.  

Maximizing the benefits 

When it comes to choosing a roof that will keep your home more efficient and cool, the material the roof is made of is just the start to the decisions you’ll need to make. You will also need to consider aesthetics and ventilation.  

When it comes to picking a color, light-colored roofs reflect more sunlight, while darker roofs absorb more heat. A light-colored metal roof offers a strong combination of reflectivity, fast heat release and curb appeal. Additionally, some metal roofs can be paired with UV-reflecting, cool roof coatings. These make them even more durable and effective and are not available for asphalt shingles.  

As for ventilation, even an energy-efficient metal roof can underperform if attic airflow is poor or insulation is inadequate. It is important that you work with a roofer who evaluates the full system, not just the roof surface, because a reflective roof paired with proper ventilation can help improve comfort during peak summer months. 

Conclusion 

For homeowners considering an upgrade, metal roofing offers cooling benefits along with durability, low maintenance and long-term value. While reflective shingles can help reduce heat absorption, metal roofing often performs better over the full life of the roof.
