It is simple. We all learn in school how it is best to wear a white shirt on hot days to beat the heat. White reflects the heat off, keeping you cool while dark colors absorb heat and make you feel hot. Using this principle, painting your roof white or installing light colored roofs will help you keep your home cool. This is what is known as the cool roof. Cool roofs stay cool by reflecting and emitting as much the sun’s energy. With minimum heat transferred into your home, cool roofs help you cut down your cooling expenses and considerably reduce the energy bills.

1. Cool roofs
It is simple. We all learn in school how it is best to wear a white shirt on hot days to beat the
heat. White reflects the heat off, keeping you cool while dark colors absorb heat and make you
feel hot. Using this principle, painting your roof white or installing light colored roofs will help
you keep your home cool. This is what is known as the cool roof. Cool roofs stay cool by
reflecting and emitting as much the sun’s energy. With minimum heat transferred into your
home, cool roofs help you cut down your cooling expenses and considerably reduce the energy
bills.
Just like in ancient Greece, the roofs can actually be painted white or can be light colored. Cool
roofs are designed with two special characteristics- solar reflectivity or ability to reflect sunlight
and thermal emissivity which means the roof’s ability to give off its absorbed heat.
While a dark colored normal roof may reflect 5 to 20 % of sunlight, a light colored roof can
reflect 55 to 90 %. A cool roof with high emissivity will release a greater amount of absorbed
heat faster. On a hot summer day, a cool roof can stay 50 0 F cooler than a dark color roof that
can heat up to 150 0 F.
While color of the roof plays an important role, with advanced technology, special reflective
coatings are also available that can be applied on existing roofs to make them cool roofs, an
easier option for home owners who don’t want to replace their roofing.
Cool roofs make the interior of your home comfortable and also increase the life of the roofs. A
cool roof expands and contracts less than a normal roof with fluctuating temperatures making it
last longer.
Cool roofs also reduce energy consumption and are best for the environment as they reduce the
carbon footprint. One of the problems in cities is the urban heat island effect- which means the
temperature in cities is almost 20 deg F higher than the surrounding countryside. This effect
leads to the formation of smog and is considered to be one of the causes of global warming. It
also causes serious health problems for residents. Installing cool roofs has helped reduce the
urban island effect.
Cool roofs have thus become an important feature of homes especially in urban areas. While you
settle for the right type and color of the roof, installation of the roof is equally important. A roof
improperly installed will cause great inconvenience and wastage of time and money. Proper
insulation, roof deck protection, leak barriers and comprehensive attic ventilation is paramount.
So purchase your roofing system as a whole from a company which manufactures and installs it
for you. Champion Window is a reputable company manufacturing and installing roofs. Roofs
are available in various colors with protection against storm and winds and come with life time
warranty. Reviews of Champion Window have many customers who vouch for the good
performance of the roofs and the good service offered by the company.

2. If you are planning to replace your roof, call them. Don’t cut cost by mixing and matching parts
from different companies. Buy the whole roofing from one company and get it installed from
them.
Let this roof be your last roof.
