Your roof is the major source of heat transfer in your house. Hence, you can decrease the heat transfer by adding insulation in your attic. A poorly insulated attic will boost energy usage in both winter and summer. You can add either standard attic insulation or one specifically designed to be applied to the roof’s underside. Adding any insulation type will make the home more energy-efficient just from reduction in heat transfer.

It is imperative to consult a roofing expert about the perfect way of insulating your roof and attic. Improper insulation might cause issues with condensation which can damage your home and roof. Moreover, depending on the home and climate, insulation may need to be added in a specific way.

Cool roofs are light-colored as compared to conventional black asphalt/dark wood shingles. Also, they save energy by reflecting heat and light away instead of absorbing it. It is called the “albedo effect” and several studies have reported significant energy savings from just lightening a roof’s color. Again, make sure to consult with roofing professionals regarding this. Do you know that cool roofs can be 50-60 degrees much cooler than the traditional dark-colored ones?

These roofs also decrease the cooling load on the house while decreasing utility costs and saving energy. By reducing your home’s heat retention and solar gain, a white roof also increases comfort. Done under the guidance of roofing professionals, it decreases the heat island impact to which the home’s dark roof contributes.
