It is pretty hot out there these days so I thought I would talk a little bit about the colour of roof shingles you choose for your home, especially in this heat wave weather.
Did you know the colour of the shingles you choose for your build can have a BIG impact on the building’s energy efficiency? The colour of shingles can have significant effect on the temperature of the upper levels of the building in particular. Attic temperatures can vary widely depending on colour choices and this in turn can reduce or increase energy consumption greatly depending on the time of year.
Studies have shown that wood roofing panels under black shingles were ten to fifteen degrees warmer than the same panels under white shingles on a sunny day. However, during the evening, the black-shingled roofs also tended to lose heat faster than did the white-shingled roofs.
In the evening, both black-shingled and white-shingled roofs generally experience similar nighttime temperature profiles. So, to put it simply, shingle colour (which dictates how much radiation/heat it will absorb and retain) is the main factor in dictating temperatures.
In warmer climates, lighter colours will reduce heat absorption from the sun while cooler climates will want black shingles that help to melt winter snow. You can compromise the shingle colour to better suit home design by selecting shingles with flex of white or grey. Consider blends like grays to get the most out of your shingles all year round.
Roofing is a long-term commitment that must balance good looks with good energy efficiency. Be sure to consider all the factors when choosing the right shingle shade for your roofing project.

All in all you want to say that you need to color the roofs according to the weather conditions. You must color shingles two times in a year relevant to the weather.
