Why is green stuff growing on the outside of my house?

Hampton Roads is home to lots of military folks who often become first-time homeowners while their stationed here. I often get the question; “why is my siding turning green”? The first words out of my mouth are usually, “welcome to Hampton Roads”. Well, if you’d like to know what’s growing on your home’s siding and roof, keep reading.

 The unsightly organisms that grow on the roofs and siding can be moss, algae, lichen, and sometimes mold. All of these can create black streaks, brown or greenish blotches on your home. From a distance, it’s hard for a casual observer to know exactly what it is so I’ll break it down to help you understand.

 Mosses are classified as plants and use photosynthesis which turns sunlight and water into food they need. Algae, according to the University of Florida, are in the plant kingdom, but technically they are not plants.

 Algae range in size from microscopic to meters long like what you see growing on the side of your home as the algae spreads causing huge green, unsightly patches. These organisms may look like true plants, but unlike plants, algae do not have roots or true stems and leaves.

 Algae, like Moss use photosynthesis as do lichens, which are combination organisms that have algae or bacteria living within a structure made of fungus, with the fungus dependent on the food the algae or bacteria make via photosynthesis. Mildew are solely fungi, also an independent kingdom from a botanist’s perspective. They get energy by feeding on organic matter where they live. They don’t use photosynthesis, so they don’t need sunlight that’s why you will most likely see mold or mildew living inside walls or crawlspaces where there’s plenty of moisture and no light.

 Our climate here in Hampton Roads is the perfect combination of precipitation and humidity for the growth of algae, moss, and lichen which is what you are most likely to find growing on the outside of your home.

The algae discoloration typically begins as small spots on your roof then quickly transforms into streaks on the roof plane. By the time the algae are visible, its likely been present for several months or longer.
