<p>The capacity of a roof to absorb heat played a vital role in maintaining indoor temperature stability. Employing composite coatings made from natural materials presented a promising solution for contemporary roofing systems. This study explored the impact of incorporating natural stone powder combined with epoxy as a coating on galvalume roofing, focusing on its effects on thermal conductivity and indoor temperature reduction based on powder sizes. Temperature data were gathered from a small structure featuring a roof treated with the composite coating, which included andesite natural stones. Thermocouples were placed 20 cm above the roof, on the coated surface, beneath the galvalume layer, and inside the room to monitor heat transfer. The findings revealed that adding natural stone powder to roofing materials effectively lowered thermal conductivity and indoor temperature. The degree of temperature reduction varied depending on the size of the stone powder. Ultimately, the study confirmed that the inherent characteristics of natural stone powder size contributed significantly to enhancing a roof's insulation properties and reducing heat buildup indoors.</p>
