If the environmental conditions are just right, algae can quickly develop on your roof. Before you know it the problem will rapidly expand and cover the entire roof; it can even spread to other roofs in the neighborhood. Once algae have developed, their airborne spores will be quickly carried from rooftop to rooftop, infesting the whole neighborhood. All types of roofing materials from wooden shake to clay tile to asphalt shingle are susceptible to algae infestation if the proper steps aren’t taken to prevent and treat it.
When algae and fungus spores land on your roof and are able to grow, they will appear as black stains. If you think the black stains on your roof are a result of pollution, soot or jet exhaust, think again. All these spores need to grow and spread into ugly black patches are heat, moisture and nutrients. The heat and moisture come from the air and the natural weather conditions, and the nutrients may come from dirt and even from the shingles themselves due to the limestone filler that is typically used to manufacture the granules. The more the moss or algae grows, the more moisture it will hold, and the wetter the roof will remain. This is the perfect condition for rotting, which can spread through the shingles and into the wooden decking and eventually cause tremendous damage. This is why it’s so important to trim any tree branches that are shading the roof.
There are different types of shingle roofs that vary in quality. The price of the shingles will often indicate the quality, as well as the presence of a manufacturer’s warranty. Builders and roofers typically apply roofs in the low to medium quality range, whereas custom homes are usually constructed using the higher quality roofs. Many of the new roofs applied on older homes are a result of black stains, because in the past it was believed that the only way to get rid of them was to re-roof the entire house. In fact, some estimates say that more than half of all roofs are replaced for aesthetic reasons and not because of functional reasons. Fortunately, it is now possible to invest in roof cleaning services that get rid of those nasty black stains without replacing the whole roofing system with expensive new shingles.
