Cleaning Extends the life of a metal roof

Regular cleaning will extend the life of your roof and maintain the integrity of the panels. It will help remove any particles that could degrade the paint system or the roof.

Get rid of the elements.

Chemicals present in acid rain and pollution particles, degrade the metal roofing paint system hence, it is important to get rid of the polluting elements. These elements include airborne dirt, leaves, small sticks, water stains, acid rain, rust stains, mould and mildew. The chalking of the roof indicates the presence of such chemicals. The roof panel can get extensively damaged due to exposure to sunlight and UV rays. In such cases, the paint system loses its adhesion to the surface, and the roof begins to fade.

Aesthetics of a metal roof

Cleaning helps to maintain the aesthetics of your beloved roof, especially since you paid a large sum of money for a metal roof. All you need to do is periodically clean it and keep the dirt and other visible elements from making your roof look dirty, mouldy, or discoloured to the naked eye.

Plain water is enough to get rid of dirt, dust and other harmful elements from metal roofs. You can use a water hose to effectively clean the surface of pollutants.


The common detergent is also an effective solution to clean metal roofs. Mild laundry detergents, car washing soap, and commercial and industrial detergents are good cleaners for roofs.


If the roof gets stained due to oil, paint, grease, and graffiti, solvents can clean them. Solvents can also rid the non-water elements. Remember to use solvents only on affected areas on the roof and never to clean the entire roof.


If your home is in a humid climate zone, then the excessive shade might encourage the growth of mildew, algae, or mould growth on the surface. However, they are easy to clean off.


Rust stains may indicate that your roof has begun to prematurely corrode, but often this is actually because the roof is in contact with uncoated metal pieces and particles that create rust stains over time.
