Rely On An Atlanta Roofer To Increase Energy Efficiency

By Andrew B. Spates


One of the most effective ways property owners can save money on heating and cooling costs throughout the year is by making sure the building has enough insulation. Insulation plays a key role in minimizing heat loss that occurs through the roof and walls of the building. A qualified Atlanta roofer can evaluate commercial and residential buildings to determine if they have the proper amount of insulation.

The laws of thermodynamics dictate that warm air will naturally flow toward cooler areas. This means the cool air from an air conditioned building in the summer will attempt to flow outside. When the temperature drops outdoors, cool air from outside will try to flow toward the heated air inside.

The insulation's density, type of material and thickness determines its level of resistance. The industry measures the resistance by a standard called the R-value. The higher the thermal resistance of an insulation product, the higher its R-value will be.

The Department of Energy sets R-value standards for buildings depending on their geographical location. Buildings in regions with extreme temperatures require a higher R-value to achieve maximum energy efficiency. Buildings in regions with milder climates require insulation with a lower R-value.

Because attics frequently have poor insulation and are rarely heated or cooled, they lack energy efficiency. When it is cold outside, the attic will be about the same temperature as it is outdoors. When it is hot outside the attic may be between 30 and 40 degrees warmer. Adding the proper amount of insulation reduces heat loss and increases efficiency.

Any professional roofer can inspect a building's existing insulation to determine its R-value. The DOE occasionally changes the standards based on climate data. This means an older building, which had the proper R-value at the time, does not comply with current standards. Installing additional insulation will raise the R-value and result in lower energy bills year round.

A local roofer can inspect the existing insulation and determine if more is necessary. The three most popular types of insulation are foam, fiberglass, and cellulose. The roofing expert can assist the consumer in choosing the right type. With the right insulation, building owners will save money on monthly energy bills. Increasing the building's energy efficiency has the added benefit of saving wear and tear on the heating and cooling system.
