Southport Roofing: Article About Roof Stains
When homeowners think of things that can damage their roofs, they think of animals, weather and foot traffic from humans. They often don't think about the small organisms that can cause damage as well. Organic material such as algae and fungus can accelerate the deterioration of nearly any roofing material. For most homeowners, the first sign that they need to have their roofs professionally cleaned by Southport roofing experts are roof stains.
If homeowners were to walk outside and look at different houses on their street, they are likely to spot a few roofs that have stains. These stains can come in many different colors, but they often form in areas that are shady or on parts of roofs that face the north or west. This is the result of algae, lichen colonies and moss. These organic materials often grow on roofs because of the mineral based granules that make up many roofing types such as asphalt shingles. The granules serve as a food source for them, and as they start to feed on them and on the bacteria that gets caught in the roof, the roof starts to deteriorate quickly.
Algae is one of the most common living organisms found on roofs, making it a major culprit of roof stains. Damp roofs trigger the growth of algae, which is why this organic compound is typically found on roofs that are shaded by trees or located in humid areas.

It can survive on roofs since it only requires pollen, dust and other organic materials for sustenance. One of the biggest problems with algae stained roofs is that they absorb heat from the sun rather than reflect it. This creates a super heated attic, which breaks down roofing materials quicker and makes the house harder to cool effectively, raising energy bills.
Moss requires a lot of water for sustenance. This is why it often doesn't form on deeply slopped roofs; the water drains too fast for it to be absorbed. However, once moss takes hold of a roof, it traps water in place to keep it from draining. As it grows, it starts to work its way under the roofing material, effectively removing it from the roofing deck.
Lichens are a type of fungus that cause roof stains and create a crust like growth on shingles. This organism damages roofs with its root like tentacles, which eventually create holes in the roofs and provide moisture an easy pathway into the homes. Once the holes are created, homeowners have to replace all of the affected shingles.
