If you are building a new home, decide during planning whether you want a cool roofing, and if you want to convert your existing roofing, you can:
Retrofit the roof decking with specialized heat-reflective material.
Re-cover with a new stone coated steel roofing panels.
Replace the roofing with a cool one.
A cool roofs uses material that is designed to reflect more sunlight and absorb less heat than a standard roof. Cool roofs can be made of a highly reflective type of paint, a sheet covering, or highly reflective tiles or shingles.
By installing a cool roofing, you can lower the temperature of your roof by up to 50°F and save energy and money by using less air conditioning. Cool roofing make spaces like garages or covered patios more comfortable.
As cool roofs are becoming more popular, communities will benefit from fewer power plant emissions and less demand for new power plants. Cool roofing can lower outside air temperatures, reducing heat islands in urban areas.
Nearly any type of home can benefit from a cool roof, but consider climate and other factors before you decide to install one.
GREEN ROOFS and Cool Roofs
You may also consider installing a green roofing. Green roofs are ideal for urban buildings with flat or shallow-pit roofs, and can include anything from basic plant cover to a garden. The primary reasons for using this type of roofing include managing storm water and enjoying a rooftop open space.
Green roofing also provide insulation, lower the need for heating and cooling, and can reduce the urban heat island effect. This roof type can be much more expensive to implement than other efficient roofing options, so you should carefully assess your property and consult a professional before deciding to install a green roof.
