Metal roofs do not.
How hot does a black roof get.
Why would it be much different with a roof shingle.
Black is a color that attracts heat be it through a black t shirt in the height of summer or black metal roof over a shed.
One of these things is color and other materials used to make the roof.
I have a roof with a 2 12 pitch aka hot mop roofing.
No pebble protection by august the roof had more blisters and ripples than a man could count.
Although black lacks the degree of reflective qualities provided by lighter tones it can still serve as a viable color for your metal roof installation.
It layed perfectly flat prior to open cell foam being installed against the underside.
If black is your preferred roof color you might think that a black metal roof would absorb more radiant heat since it is dark.
A dark roof absorbs more heat from the sun.
A lot of things can have an effect on the heat of your roof and this can have implications for the heating of the rest of your home.
However that is not the case when it comes to modern roofs.
