Before You Buy An Effective Roof Cleaner


While stain-fighting chemicals contain different elements, their level of aggression on moss, molds and mildews varies accordingly. Roof algae is a common cause of tough stains on plastic roofs of RV, shingles and hard coverings of buildings.

Apart from extending the lifespan of roofing materials, they make these stains less noticeable for a long time. Also, UV rays from sunlight can be blocked by roof-cleaning ingredients. Effective cleaners should make a difference in the appearance of any roof.

However, non-toxic roof cleaners are friendly to the environment and affected materials. It’s better to buy cleaners with an eco-friendly formula. These types don’t pose any threats to your health and they prevent the hassles of scrubbing after any application.

Usually, bleach-free roof cleaners contain biodegradable ingredients. When applied on roof surfaces, they can offer high levels of protection for many months.

Type Of Roof Cleaner

The method of applying roof-cleaning solutions are often indicated on their labels. Consider cleaners that can be applied with simple steps. Normally, roof-cleaning professionals use pumps to apply these chemicals.

Without scrapping the roof’s surface, it might be difficult to apply deep cleaning with the roof cleaner. Also, scrubbing brushes with long handles are ideal for spreading cleaning solutions manually.

Tough stains often don not resist wire brushes. Since the bristles of these brushes are strong, they are suitable for sweeping metal and concrete roofs before applying the cleaning solution.

When the roof’s surface is dirty, it might be necessary to clear accumulations of loose paints and debris from the roof surface.


It’s a common practice for roof-cleaning manufacturers to indicate the coverage size of their formula. If you are considering your budget, the coverage of any roof cleaner is an important factor.

You can dilute 1-gallon concentrated cleaners and get 10 gallons of effective solutions. However, over-dilution can affects the effectiveness of the formula. At least a coverage size of 2,500 square meters of any diluted cleaning solution is reasonable.
