Something is Growing on Your Roof

If you live in a most and humid area, you must realize that your roofing system is susceptible to a number of strange growths; the risks are even higher when such a house is built at a place where it receives very little or no sunlight at all; the sun’s rays can be obstructed by surrounding tall buildings or even trees and any shades that block off the sun from the roof. The development of those growths will start by causing discoloration or ugly black stains but eventually, they will destroy the integrity of the shingles leading to water penetration and other types of damage; thankfully, being keen on roof cleaning methods can easily solve this problem before it deteriorates.

Algae: The organism can appear as black or green streaks and they easily adapt to any weather conditions and because they are airborne the spores can spread quickly. They get their main water source from dew but they can survive for a long time without water; no pressure roof cleaning using copper and zinc based chemicals can prevent their growth.
Lichens: This basically grows on wooden or asphalt shingles and appears in green spongy lumps growing in random but having a good grip of the roofing material; they normally flourish in places with high humidity and intensive shade. They appear in different colors ranging from silver to gray; gray to green and orange to yellow and form crust like leafy structures. Lichens have a very strong hold and if your roof gets infested with them it will likely destroy the protective coating of the asphalt shingles. An eco-roof wash using no pressure roof cleaning is the best way to remove lichens from your roof before it is too late.
Moss: This is an organism that appears in white-yellowish colors and will often thrive in areas that have high humidity and frequent rainfall. Even though moss appears to be harmless to most people, you should not allow it to thrive on your roof because it has the capacity to cause extensive damage to any roofing material. It is able to retain and harbor water and, as a result, it encourages the penetration of water to the protective layers of the roof eventually leading to structural leakage.

Growth Control: There are several methods of regulating the growth of moss, algae and lichens; you can use chemical based or non-chemical based control methods that are accomplished through roof cleaning. The best chemical based methods use a combination of environmentally friendly chemicals that get applied to the roof and left to sit there for a while before the roof is washed clean to remove the infestation. You may also choose a no pressure roof cleaning method in cases where the infestation is not too severe.
