ROOF WASHING
ROOF WASHING

Roof washing is the procedure for cleaning roofs of algae, mold, mildew, lichen, and moss. A roof’s ability to function can be extended by cleaning or washing it. Algae and other types of build-up commonly grow on the north and west sides of roofs that are sheltered or receive less sun, reducing the life expectancy of the roof. The quantity of sunlight received by a roof, and consequently the amount of heat absorbed by a building, can be affected by the presence of soot, dirt, or biomass. In this piece, we’ll look at the cost of soft roof washing, as well as companies, services, and chemicals. Let’s get started!

Soft Roof Washing

Dirt, mold, mildew, and lichen can all be removed off the surface of your roof with soft roof cleaning. Other cleaning procedures may harm shingles or gutters, but this method will not.

What is soft roof washing?

Soft roof washing is a cost effective and safe technique to clean your roof without causing damage. The biodegradable liquid soap used in the soft wash system loosens dirt accumulation and allows it to be easily washed away.

Soft roof washing is a cost-effective way to clean your roof. Some employ a high-powered sprayer to spray a soapy solution into your roof’s drain spouts, which is then drawn back down the building’s outer surface by gravity, loosening and carrying away dirt and debris.

Because the mixture used simply comprises soap and water, it is a safer option for pressure cleaning because it has no negative effects on your shingles or gutters. It’s risk-free for you, your family, and your landscaping!

Steps for Soft Roof Washing 

  • Firstly, ensure that you are wearing suitable safety equipment when cleaning roofs. Long-sleeved shirts, rubber gloves, eye protection, and shoe covers are all examples of this.
  • Prepare the roof: It’s critical not to merely splatter chemicals all over the roof. The best way to ensure that the chemicals stay in place is to take them slowly and methodically.
  • Apply the chemicals with a spray sprayer or a high-pressure washer equipped with a brush nozzle to offer scrubbing strength for stubborn spots.
  • 15 minutes later—Soft roof washing necessitates patience because the chemicals need time to work. The chemicals will not function as well if they are administered when it is too hot outside.
  • Rinse thoroughly with water—Once the old filth has been broken down, it must be properly rinsed away with fresh water. This ensures that no residue is left on the roof, preventing algae and mold from regrowing.

There are a variety of chemicals available for soft roof washing, but choosing the correct ones to avoid damage or harm is critical.

  • 1.5 x square footage of home = Square footage of the roof

Surfactants are utilized to aid in the distribution of the cleaning solution throughout the surface. They’re also good for preventing rust. Cationic and anionic surfactants are the two types of surfactants. Surfactants with a positive charge are cationic, while those with a negative charge are anionic.

Chemical adhesion is improved by using different types of surfactants depending on the cleaning application. Roofs are cleaned with roof washing chemicals to remove stains and discoloration. If not handled properly with the right chemicals, stains can be extremely difficult to remove.

Some roof stains, such as algae, are truly living creatures. An acid or an algaecide can be used to eliminate these. Algae is not hazardous to humans, but if left unchecked, it can cause difficulties for roofs.

Common chemicals used for soft roof washing

The following are the most commonly used chemicals in residential soft wash roof cleaning:

#1. Corrosive (sodium hydroxide)

This is the most powerful of the chemicals, and only experienced professionals should use it. Caustic can burn the skin if it comes into contact with it, so use caution when applying it.

#2. Surfactants (detergents)

This substance aids in the breakdown of grime and stains, making them easier to remove with water. Surfactants also aid in the cleaning of roofs by reducing the formation of new stains. Surfactants can be anionic, non-ionic, or cationic.

 #3. Bleach

For many soft roof washers, this is a popular option. The powerful oxidizing qualities of bleach aid in the removal of stubborn stains caused by algae, fungi, and lichens that form on roofs if left untreated. Bleach also kills mold spores and algae cells, which helps to prevent fresh stains from forming on roofs.

 #4. Water

Although a hard scrubbing brush and water will remove most stains, some stains will require further assistance. Multiple chemicals are sometimes blended to make a powerful cleaning solution capable of removing tough stains.

#5. Vinegar

This is a popular choice because it is less expensive than bleach and acids, yet it is still efficient at removing algae and fungal stains off roofs. Vinegar is also non-toxic to most green plants and trees, which is useful when working with them.

 #6. Hydrochloride acid

Soft wash roof washers who want to utilize acids have another alternative. Water can be used to dilute hydrochloric acid, but it’s crucial to make sure the solution isn’t too powerful. This acid must be used with caution because it can burn skin and ruin clothing if it comes into touch with it.

#7. Biocides

Mold spores, algae cells, and other microorganisms that develop on roofs can all be killed by biocides, which are chemicals meant to kill live creatures. Some biocides are found in nature, while others are manufactured in a laboratory.

#8. Soaps

Soap is used in soft wash roof cleaners for three reasons: 1) to add extra surfactant to assist in breaking down stains; 2) to provide a natural source of biodegradable enzymes, and 3) to help destroy algal cells.

#9. Algaecides

Algaecides are chemicals that are used to assist and inhibit the growth of algae on roofs, as their name implies. Copper sulfate salts are used in these roof cleaning chemicals to keep fresh algae from forming on the roof.

#10. Trisodium phosphate (TSP) 

This is a powerful chemical that can quickly erase even the toughest stains. TSP must be diluted before use. However, one of its advantages is that it has no residual characteristics.

#11. Sodium carbonate peroxyhydrate (SCPH)

SCPH is likewise an algaecide, although it’s more typically used for roof washing than other chemicals because it’s less corrosive.

Conclusion

Soft roof washing is the most effective and safest method for removing dirt and stains from any roof. Soft roof washing is done with chemicals, which have a variety of advantages. Some may need to be mixed or diluted before being sprayed on the roof, but this is a reasonably simple operation as long as everyone wears the appropriate safety gear.
