Asphalt shingles absorb a lot of heat, and that heat doesn’t stop at the roofline; it streams into the structure and increases the indoor temperature by 20 to 25 degrees [source: Florida Solar Energy Center
]. Metal roofs, on the other hand, reflect the sun’s heat away from a building, leading to energy savings of about 50 percent, and they can be about 100 degrees cooler on the surface than traditional asphalt roofs [source: MRCA
]. A shingle roof also weakens and curls over time, making it less of a full-proof barrier for the effects of rain, wind and other environmental forces, and necessitating roof maintenance and earlier replacement. A metal roof doesn’t take in all of the heat, it is very resistant to the elements when installed correctly, and it lasts much longer, needing little if any maintenance.Our metal roofs all receive the coveted Energy Star rating.
