It wasn’t long before that you got a new roof installed. It looked beautiful and colorful. Even before you have finished admiring it, you see that the roof has started appearing dull and lifeless. There are stains all over the roof which are visible even from a distance. There are various reasons for these stains to appear in a new roof.
Why stains form?
Usually people think that nature has caused the roof to develop stains. They think that the birds, weather, pine needles or the trees cause the staining of the roof. But it is not true at all. The truth is that air borne spores like fungus, algae or mold cause these stains. The innocent looking microscopic spores fall on the roof top and gradually multiply. Over a period of time they appear as stains to human eyes. The lime stones which are present in the asphalt based shingles provide a perfect breeding ground and source of food for these spores and there they develop real fast.
It is quite usual to find roof stains on the areas of the house which are in the shade of tress or towards the north. The reason behind this phenomenon is that the area that is moist is prone to stains. Sunshine doesn’t allow the spores to breed. A moist area is a perfect place for the breeding of the spores. It is essential that you get these roof stains treated in time otherwise they may lead to the cracking, drying or curling of the shingles and thus destroying them permanently.
not ever clean your roofs with chlorine bleach because chlorine bleach harms the surface of the roofs and the plants that it comes in contact with. Chlorine bleach just cleans the outer surface but doesn’t really provide any prevention for further growth. Thus within 2 years or so, again you will find algae growing back and the roof appearing stained once again.
Another important point that you must always keep in mind is that you should start the cleaning and the washing from the top portion of the roof. The water that you spray for cleaning the shingles should be sprayed down, in downwards direction and not in the upward direction.
There is a very simple reason behind this basic precaution. If you spray the water from the bottom then the spray of water can get under the shingles, through the gaps. Thus it may start leaking into the house. Imagine creating another problem in trying to solve the earlier one! You should also remember to use simple water hose to spray the water. You should never use the commercial waiter pressures to clean the roof because the high force and the pressure will definitely clean the stains but will destroy the surface of the shingles permanently. The pressure of the commercial washers is so high that they may ruin the entire roof.
In the end of it all just ensure that none of the roof shingles have been destroyed. If you find any cracked or curled shingles do get them replaced immediately for proper maintenance of the roof.
