During winter your home needs heating.
Roof shingle color heat.
Roof absorption and reflection are not only determined by color.
Roofing color effect on cooling costs.
A dark roof color can tap heat from the sun and transmit it into your home making it warmer.
How roof color reflects or absorbs heat before you learn anything else about roof color take away this fact.
In contrast dark colored roofs absorb heat much like dark clothing and heat the rooms within your home.
What s the impact on your pocket.
You can compromise the shingle color to better suit home design by selecting shingles with flex of white or grey in warmer climates.
Roof color choice also may affect shingle life in those climates.
Therefore dark roof shingles are beneficial in colder climates where winters are particularly long and summers are brief.
For instance an attic under a black colored roof can be 30 degf.
Light colors would be in order there.
In warmer climates lighter colors will reduce heat absorption from the sun while cooler climates will want black shingles that help to melt winter snow.
Lighter colored roofs tend to reflect the sun s heat rays resulting in your home being cooler especially in the summer months.
After all darker colors absorb heat and lighter colors reflect it so the climate in your area matters when you are choosing what color shingles and type of roofing material that you plan to use.
Of course lighter colors reflect the light keeping things cooler while darker colors absorb the light and keep warmth in.
