When your composite shingle roof has stains on them, it looks aesthetically pleasing. The most common cause of stains is algae, which will start growing on your roof. If left unchecked, they can keep spreading and destroy the beautiful appearance of your composite shingle roof.
However, if it isn’t algae but moss, you have a huge problem on your hands. These organisms will penetrate your roof over time and damage the shingles through curling. If you don’t remove the moss, strong winds during storms will tear apart your roof.
Regardless of whether it is algae or moss, removing the stains from your roof is extremely important, both aesthetically and structurally. Here are some tips that will help you get rid of stains on your composite shingle roof:
Safety is important
As you are working with chemicals, it is important that you take care of yourself and the surroundings. Powerful chemicals can damage your vegetation, which is avoidable, as long as you take the necessary precautions.
Before you start cleaning your roof with chemicals, make sure that you spray water on all the plants in and around your house. Use tarps to cover the plants so that they are safe from chemical runoff and overspray.
Next, make sure that you always wear protective clothing as you don’t want to come in contact with the chemicals. Clothes with long sleeves, goggles, gloves high-traction sole shoes, and pants are a must.
Cleaning algae/moss from your roof
It is easy to remove algae and moss from your composite shingle roof with chlorine-based bleaches. However, avoid using them as much as possible as they will damage the shingles. On top of that, they can decrease the shingle’s elasticity, which makes them brittle. Also, chlorine-based bleaches will damage the vegetation of your house.
Your best bet is to use oxygen bleach, which is safer than chlorine-based ones. It won’t discolor your shingles or damage the plants surrounding your house. Mix it with water and spray the mixture on your roof. Make sure that mixture is on your roof for at least 15 minutes to do its magic. Scrub the composite shingles of your roof to remove the algae and moss. Once you finish cleaning, rinse your roof with a hose.
