Surprisingly, many people think of metal roofs as having limited color options. Perhaps they think the color matches the type of metal. Silver for steel, tin and aluminum; reddish-brown for copper; dark gray for lead. As if those are the extent of the color options.
Now that shingle composition has changed to mostly fiberglass and limestone, the GM blue-green algae thrives, using the limestone as their source of food. Why is it black and only found on the north- and east-facing sides of the roof? GM has the ability to form an outer coating, protecting it from UV rays. When there is no light or low light, GM has a blue-green color. GMâs other self-protective factor is that it enjoys the cooler, shady areas of the roof where moisture is usually present.
