Metal roofs can reach 190 degrees in the afternoon, 30degF warmer than shingles. But they can still help you save money. Based on Oak Ridge National Laboratory, metal roofs can reach 140-190°F during summer, while shingles reach 130-170°F. This guide will answer “Do Metal Roofs Get Hotter Than Shingles?”, the comparison of energy efficiency, heat performance savings, and ways to cool your property.
The Short Answer
Yes, roofs made of metal get hotter when touched; however, they are able to make your home more comfortable overall:
- Metal is a better conductor of heat and makes surfaces feel hotter.
- But metal absorbs more sunlight, thus reducing attic heat when properly vented.
- Asphalt shingles retain and absorb heat longer, which slows the cooling process at night.
The main thing to consider is selection of color and installation not just the material. Find out more about our experienced Commercial roofing service here!
Heating Comparisons: Metal vs. Shingles
| Factor | Metal Roof | Asphalt Shingles |
| Peak Surface Temp | 190degF (dark) / 120degF (light) | 170degF (dark) / 140degF (light) |
| Solar Reflectance | 25-70% (color-dependent) | 5-30% |
| Heat Retention | Cools fast at night | Keeps heat for longer |
| Attic Temp Impact | 5-12degF cooler, with an air gap | Traps provide more heat |
Metal has a higher performance than shingles against shingle roof temperatures with an appropriate setup.
The Reason Why Metal Roofs Are Hot
Thermal Conductivity
The metal can transmit heat faster than asphalt and this makes it warmer on the skin. Due to their layered construction, shingles result in a minor insulation and heat transfer hindrance with a prolonged retention of heat.
Solar Reflectance Advantage
- The light colored metal reflects 60 to 70 percent of the sun’s rays, compared to. 20% in shingles.
- Dark Metal still reflects 25 to 35% of light and outperforms dark shingles (5-10 percent).
This makes it one of the coolest roofing materials if it is chosen with care. Find a professional roofing Installation Service to get the optimal outcomes!
Ventilation Matters Most
- Metal roofs properly vented (with vents in the soffit or ridge) maintain attic temperatures 10-15 degrees cooler than roofing shingles.
- In the absence of ventilation, metal’s conductivity can cause the “oven effect,” radiating heat downwards.
How to Keep a Metal Roof Cooler
Make the most of your efficiency by following these suggestions on how to cut down the heat generated by metal roofs:
- Select lighter colors:
Light gray or white is the best way to reflect heat, and keeps surfaces at 50 degrees cooler than dark shades. - Install it over a ventilated air Gap:
A gap of 1-2 inches between the decking and the metal will prevent the transfer of heat towards the attic. - Make use of Radiant Barrier:
Underlayment blocks 97 percent of radiant heat, also cooling the attic. - Install Roof Overhangs:
Shade windows and walls from reflecting heat, which reduces indoor temperatures.
When Shingles Might Be “Cooler”
- Dark Shingles vs. Dark Metal:
They have similar temperatures at peak (170-190degF) however, Shingles transfer less heat to the attic because of less conductivity. - Insufficient Attic Ventilation:
If vents are not adequate, metal roofs hold heat more than shingles, reducing their reflective advantages.

Final Thoughts
Do Metal Roofs Get Hotter Than Shingles? These are hotter to the touch, yet are more energy-efficient than the shingles in the case of proper installation. They are a preferred roofing material in hot climate regions due to high solar reflectivity, which helps reduce expenses on AC by up to 25 percent. To get the best cool roofing material, you can go with light colored metal with the correct ventilation and a radiant barrier. Contact us for assistance. Only roofing!
