The Ultimate Energy-Saving Roofs Quiz
In an effort to make your new home as green and energy efficient as possible, you are examining ways to save energy. Look up at your roof. The roof is exposed to the hot sun in summer and is also where most heat escapes in the winter. Take this quiz to test your knowledge about energy-efficient roofing choices.
Question 1 of 10
What percentage of utility costs goes to heating and cooling an average home?
... Approximately 50 percent of an average homes utility use goes to pay for heating and cooling. Employing energy efficient products and Energy Star heating, ventilation and air conditioning devices can significantly reduce those costs.
Question 2 of 10
What is your home's first and best defense against outside environmental extremes?
... The best defense against high heating and air conditioning costs brought on by the environment is an energy-efficient roof. Your roof needs to block heat from the sun beating on it all summer and it needs to retain heat inside your home during the winter.
Question 3 of 10
What property does the most energy-efficient roofing material have?
... According to Energy Star, the most energy efficient roofing materials have a high solar reflectance value. This means that the materiel has the property to reflect most of the suns energy rather than absorbing it.
Question 4 of 10
By what percentage can reflective roofs reduce their surface temperature as compared to a traditional roof?
... According to data from Energy Star, reflective roofs can reduce surface temperature by as much as 30 percent as compared to a traditional roof. This is a significant amount of heat, which you will not have to spend money to cool down.
Question 5 of 10
What is another property you should look for when choosing a roofing material?
... Secondary to solar reflectance, high emissivity is another feature to look for in a roofing material. Infrared emissivity is the ability of the material to release solar heat that is absorbed back into the atmosphere.
Question 6 of 10
What is the next important consideration after roofing materials choice, which will increase the energy efficiency of your home?
... R-value is the measurement of insulation ability to resist heat transfer and is your next important consideration. Increasing the R-value of insulation in your ceiling can cut heating and cooling costs and can be accomplished easily in most existing homes.
Question 7 of 10
What is a good energy saving step that you can take if you have a flat roof on your home?
... Consider turning a flat roof into a rooftop garden to save energy. A rooftop garden will also give you a nice place to relax, improve air quality and extend the life of your roof.
Question 8 of 10
By how many degrees can roofing materials that carry the Energy Star label reduce roof surface temperatures?
... According to Energy Star, roofing material carrying their label is always highly reflective and can reduce the surface temperature of an average roof by up to 100 degrees Fahrenheit or 49 degrees Celsius. A wise consumer looks for Energy Star approved products to help save money on energy.
Question 9 of 10
By how many degrees can a quality light-colored roof coating decrease the surface temperatures of an existing roof?
... According to Washington State University, light-colored roof coatings can reduce the surface temperature of a roof by 50 to 80 degrees Fahrenheit. Applying a roof coating can extend the life of your current roof surface and save money on energy costs without the expense of a roof replacement.
Question 10 of 10
Which roofing material tends to be more energy efficient than most in all climates?
... Although concrete and clay tile roofs are more expensive to install, they are the most energy efficient in every climate. You could also consider adding photovoltaic cells to your roof, as they will protect the surface from heat and generate electricity at the same time.
