Roofing: How Roofs Contribute to Energy Efficiency

Most people overlook the fact that roofs can easily help with energy efficiency issues in their homes. Roofs do more than protect your home from the elements and give your home an aesthetic look from afar, they are also essential to the structural integrity of your house as a whole, and a well-built roof can easily lower electricity bills, especially during temperate seasons like summer and winter. After all, you can’t expect your HVAC to do all the work in your home. Most of the time, a good roof can easily eliminate climate control issues by just being well-built and maintained! How can your roof help with energy efficiency in your home? Read on to learn more.

Proper Insulation


Proper insulation is key to having a roof that will assist in creating a comfortable living space. And one of the best times to improve your roof’s internal insulation is during a reroofing or a full-on roof replacement. These are the best times to do it since you’re already addressing existing issues on the outside of the roof, so why not schedule everything to be done in one go and save yourself the time and effort for another schedule in the future to beef up your roof insulation?


A well-sealed and insulated roof can do wonders for your home. During summer, a well-insulated attic beneath the roof can prevent your living areas from becoming stiflingly hot, and in the winter, a well-sealed attic prevents your internally heated air from leaking into the attic space. Partner this up with good roof vents, and your roof is guaranteed to last longer and provide great energy efficiency!


Good Ventilation

Ventilation is essential to your roof’s overall health. After all, a roof that has poor internal ventilation leads to deterioration, which will then affect your home’s energy efficiency. Insulation makes sure that the heat is properly trapped in the attic, and ventilation makes sure that the trapped heat is properly circulated out of it. But what is the relevance of proper air circulation to your roof and its energy efficiency?


The answer is the effect of heat on your roofing materials. Like how chimneys work by making sure the smoke and other pollutants from combustion are safely diverted away from living spaces, proper ventilation makes sure that trapped and stuffy air is safely circulated out of your attic. That trapped and stuffy air is hot and can become unbearably so during summer, which can warp your roofing shingles and reduce their service life as well as put a strain on your HVAC system as it tries to cool your indoors with air conditioning. Heat-affected roofing shingles can eventually deteriorate and will lead to leaks. Warm and humid air can also condensate in the nooks and crannies of your attic, causing invasive growths like mold and mildew to settle in as well as causing damage to the wooden roofing materials.


Solar and Heat Reflection


This is an important thing to remember when trying to cut your electricity bill. The more heat and sunlight your roof can reflect or reject, the cooler your attic will be. The lower the temperature of your attic (which is usually the hottest and stuffiest part of your home), the less strain it will put on your HVAC system as it tries to cool down your home. To sum up, making sure that the materials on your roof reflect as much heat and sunlight as they can is the same as trying to conserve electricity bills while using your HVAC.


Like how the color of your siding affects the amount of heat that is retained through constant exposure to the sun, the same principle applies to the color of the shingles that are attached to your roof. Darker colors retain more heat, and lighter colors absorb way less sunlight. So, the more heat is retained in the shingles, the more heat will be transferred down into the attic space, and that will cause energy efficiency issues that will inevitably increase your electricity bill as your HVAC struggles to keep a comfortable interior temperature.


Fortunately, many roofing contractors and manufacturers offer the choice of reflective and energy-efficient shingles. These types of shingles last longer, retain their color better even when exposed to constant ultraviolet (UV) rays and work best with a properly insulated and ventilated roof.


Radiant Barriers


Installing a radiant barrier is one of the best ways to assure the effectiveness of an energy-efficient roof. It looks like silver paint that is applied onto the underside of your roofing deck, but it is actually a coating that is meant to reflect heat away from your attic space. They’re usually composed of highly reflective material like aluminum foil and are applied onto one or both sides of a selected substrate material. The substrate materials can range between kraft paper, plastic films, cardboard and even oriented strand boards (OSB).


Whichever the case may be, installing radiant barriers guarantee not only better heat reflection for your roof, but also helps in insulating and keeping your attic’s temperature at a good and manageable level. Paired with well-functioning and properly placed roofing vents, your roof is assured to last long, provide great assistance to your home’s overall energy efficiency and prevent your roofing materials from cooking up from too much heat.
