Today, the most commonly used roofing materials in the United States are asphalt shingles. They come in a variety of attractive colors and are ordinarily economical and durable. However, they are prone to having lichen, moss and algae grow on them. These organisms can take hold on a roof and mar its appearance at best or cause roof damage at worst. A homeowner might spot these on the house's roof or may simply be concerned that they exist somewhere out of sight. In either case, a roof inspection should be left in the hands of a professional. Essex County roofers have the expertise to identify, eradicate and prevent these growths.

What grows on roofs is almost always either lichen, moss or algae, and all three can be present at once. Moss is a plant with no roots that thrives in shaded, moist environments. Lichen is a combination of algae and fungus. The most common growth on roofs is algae called Gloeocapsa magma that causes roof staining, leaving green or black streaks. All three of these plagues arrive on rooftops in the form of airborne spores.

Discoloration is usually the principal consequence of having algae on a rooftop. The shingles themselves aren't immediately harmed by it. Moss and lichen can be a much more serious problem.

Because these form a thicker covering than algae, they can hold rainwater the way a sponge does. The continuous presence of moisture can lead to roof material decay, bent or curled shingles and mold growth on the inside of the home.

Removing these scourges from a roof involves the application and rinsing off of herbicides or cleaning solutions containing bleach or trisodium phosphate. Moss and lichen need to be physically scraped off because even after they're dead, they'll still be attached to the roof surface. Power washing is not recommended as it can also blast off the shingles' granules and potentially void the manufacturer's warranty. Plants, home surfaces or fish ponds underneath the rooftop have to be protected from any chemical runoff.

These organisms enjoy shade and humidity, and anything that keeps those to a minimum will retard their appearance. Keeping nearby trees well trimmed will diminish the amount of shade the roof receives and will also minimize the number of fallen leaves that can clump together and trap water and moisture on the roof's surface. Because copper creates a poisonous environment for algae, when the time comes for a roof replacement, homeowners can consider installing shingles that contain copper granules.
