How Energy-Efficient are Metal Roofs?

Metal roofs often cost more upfront than traditional roofing but can provide a larger return on investment with energy-saving costs. If you are a Cincinnati resident in the market for a new roof or would like to improve the energy efficiency of you home, consider a metal roof. In addition to reducing energy costs, metal roofs are also attractive and increase curb appeal.

Energy Efficiency

A study conducted by the Metal Roofing Alliance reveals metal roofs can save homeowners up to 40% on summer air conditioning costs. Traditional shingled roofs absorb heat from the sun, causing internal home temperatures to rise. Attic and home temperatures are significantly higher with traditional roofs. Metal roofs will reflect the heat, preventing high internal temperatures in the home and attic.

High Emissivity

To choose the correct roof for your home, consider local weather conditions. For homes in colder climates, an unpainted metal roof will reflect more heat, which can be useful for winter. Sometimes that’s all that’s needed. For warm climates, painted or textured roofs will reflect heat, but also cool the home’s interior by re-emitting the heat absorbed. These types of roofs are high-emissivity and will also work in cold environments. Roofing metals, coats, paints, and finishes have different emissivity rates, so discuss the best combinations for your area with the installer.


Creating an energy-efficient roof requires more than just the metal materials. To ensure the best savings, energy-saving measures must also be present in the decking and insulation. Under the metal materials, installers will make sure to use the proper insulation to assist the metal reflectivity. When installed in layers, energy-efficient roof systems keep attics 15 to 20 degrees cooler than Ohio homes with traditional roofs.

Eco-Friendly Metal Roofs

In addition to energy efficiency, metal roofs are eco-friendly. Metal roofs are constructed from 30% to 60% recycled materials, depending on the type. After use, the metal can be recycled again. Many green companies and eco-friendly residents choose metal roofing instead for this reason. Traditional shingle roofs can produce thousands of pounds of waste after removal, with only some eligible for recycling.

Solar Panels

To make a residence more energy-efficient and environmentally friendly, add solar panels. You can install solar panels on metal roofs just as easily as traditional roofs. New solar panel and metal roof designs allow for attachment without penetrating or damaging the roof. Panels attach with a latching system. Metal roofs, solar panels, and energy-efficient windows are great ways to save on energy and make your home more eco-friendly.

“They did a great job from start to finish. They were kind, courteous, knowledgeable, they answered my questions, and kept us up to date. I was disappointed with other companies that we used before but Erie Construction was quick and it was done right the first time.”
