WILL DARK-COLORED ROOFS MAKE MY ATTIC HOTTER?
Yes, theoretically, dark-colored roofs can make your attic hotter as they absorb more UV rays than lighter-colored roofs. Your roofing material can also affect how much heat becomes trapped in your attic, as well as attic insulation and attic venting.
However, there is not a lot of stable evidence to suggest that black or dark-colored roofs will change the temperature of your attic by a noteworthy amount of degrees. The shingle colors are made with granules that are ceramic in nature and do not have a great amount of heat transfer properties, the majority of the weight of a shingle comes from the mastic or tar. The tar is the same color for all shingles, black, and would be where the roof holds most of the heat.
PRO TIPS
- Use Light- colored Shingles – Choosing lighter-colored roofing materials, such as white, light gray, or reflective shingles, can help reduce solar absorption and lower attic temperatures.
- Install Proper Ventilation: Adequate attic ventilation is crucial to allow hot air to escape and promote air circulation. Ridge vents, soffit vents, and attic fans can help dissipate heat and maintain a more balanced attic temperature.
- Apply Reflective Coatings: Reflective coatings or cool roof coatings, such as radiant barrier, can be applied to dark-colored roofing materials to increase their reflectivity and reduce heat absorption.
Before making any changes to your roofing materials, it’s advisable to consult with roofing professionals who can provide guidance based on your specific climate, roofing system, and energy efficiency goals.
