Living and vegetative roofs are energy efficient, but they are expensive and difficult to maintain. Fortunately, you don't have to replace your existing roof with a living one to boost its energy efficiency. Here are three ways to increase your roof's energy efficiency without replacing it:
Insulate the Roof
Insulation increases energy efficiency because it keeps out the summer heat and traps indoor heat during the cold seasons. Without proper insulation, your heating, ventilation, and air conditioner (HVAC) has to work harder to cool the house during the summer and heat it in winter. As a result, you experience high energy bills throughout the year. In fact, an non-insulated roof is responsible for approximately 25% of heat loss in a house. Consult a roofing contractor for the best insulation for your house.
Landscape Your Home Properly
Landscaping may also help make your roof more energy efficient. A roof exposed to direct sunlight gets heated more (and some of the heat is transferred to the house) than a shaded roof. Therefore, if you live in a warm climate, then it's a good idea to plant trees near the house so that they can provide shade on the roof and reduce the impact of the sun.
Just make sure you clean any leaves that may fall on the roof to prevent moisture accumulation. Too much moisture may encourage algae or moss growth on the roof, which leads to staining. Uncontrolled moisture may also lead to roof leaks.
Paint the Roof
The third trick is to paint the roof a light color to reflect most of the heat from the sun. According to some estimates, painting your roof white may reduce your air-conditioning costs by as much about 15% in a typical one-story residence. One of the best things about this trick is that it is low cost; all you need is to apply a reflective coating to your roof.
Indeed, you can approach it as a DIY roof project if you have the materials, tools, equipment, and safety gear. If you decide to take this route, ensure you buy the right paint for your roof type; for example, paint that may stick well on metal may not be good for wood shakes. Consult your roof contractor for advice on the right coating for your roof.
It might be a good idea to contract a roofer like US Roofing and let him or her analyze your roof's energy efficiency. After that, he or she can come up with the best solutions depending on the deficiencies unearthed.
Hi, I'm Dwight Eberstark. I am crazy about all of the different types of roofing materials available today. While upgrading the roof on my home, I looked into the material options in great detail. I studied all of the different metal materials used to create modern shingles. I also looked into switching to asphalt, wood or tile shingles. I eventually settled on bronze shingles designed to last for decades. Instead of aging, the bronze finish just continues to improve. I also switched to metal gutters that make a beautiful sound when the rain falls onto the surface. I would like to share my passion for roofing materials through this site. Thank you for coming by.
