How hot does a roof get in the summer? On sunny summer days, the roof can reach up to 190°F (88°C), depending on the material. It is not recommended to work in the roof above 90°F. The color of the roof also determines how hot it will get inside the building.

The roof is a critical area that is often overlooked in summer. Understanding how hot a roof can get and its implications for your home is essential for making informed decisions about roofing materials and maintenance. That is why our article explains everything for you. Start reading!

How Hot Does A Roof Get In The Summer?

During the summer months, a roof's surface temperature can reach astonishing levels. On a sunny day, it can climb to anywhere between 150°F and 190°F (65°C to 88°C). This intense heat can significantly affect the materials used in roofing, potentially leading to faster wear and tear, and can even impact the overall temperature inside your home.

How Much Hotter Is It On A Roof?

Regardless if you have the best roofing materials in your house, the roof's surface can be nearly double the outdoor air temperature, which might be around 90°F (32°C). In contrast, the interior of a well-insulated house might maintain a comfortable 75°F (24°C). 

This stark difference highlights the importance of adequate insulation and ventilation in your attic to prevent excessive heat transfer into your living spaces.

How Hot Does A Metal Roof Get In The Summer?

Metal roofs can indeed get very hot, often reaching temperatures between 150 and 190 degrees, similar to those of other roofing materials. However, they have a unique advantage: their reflective properties. 

High-quality metal roofs with reflective coatings can reflect a significant portion of solar radiation, reducing heat absorption. As a result, metal roofs can sometimes be cooler than asphalt shingles or other dark-colored materials, which absorb more heat.

They are also a cheaper alternative to other types of roofing. Learn more about metal roof costs here.

Is A Black Roof Hotter?

Black roofs are notorious for absorbing more heat than lighter-colored roofs. Under the same conditions, a black roof can be up to 50 degrees hotter than a white or light-colored roof. 

This increased heat absorption can lead to higher cooling costs and place more stress on your HVAC system. If you are considering a new roof, opting for lighter colors or reflective materials can significantly reduce the heat buildup.

What Temperature Is Too Hot For Roofing?

Generally, temperatures above 90°F (32°C) can be challenging for roofing installations. When roof surfaces exceed 150°F (65°C), it can become unsafe for workers to operate, and the materials might not adhere correctly. 

Roofing work in extreme temperatures poses risks to both the workers and the materials.  Many roofing companies recommend scheduling installations during cooler parts of the day or during seasons with milder temperatures to ensure safety and the best results.
