To improve your roof's energy efficiency, consider installing reflective roofing materials like light-colored shingles or metal roofs that reduce heat absorption. Ensure proper insulation in the attic to prevent heat transfer. Use cool roof coatings to reflect more sunlight and absorb less heat. Seal any gaps or cracks to prevent air leakage. Lastly, consider adding a radiant barrier under the roof to reduce heat gain further, thus lowering cooling costs and enhancing energy efficiency. For more information, visit WaterTight Roofing Indy.
