ROOF CLEANING AND TREATMENT

Consider carefully which cleaning method to use for your building’s roof. Selecting the wrong roof cleaning technique could cause lasting damage to your property. With decades of experience in soft washing building exteriors and roofs throughout Vancouver and the Lower Mainland, we possess the necessary equipment and expertise.

Soft Washing System

For decades, we’ve researched various roof cleaning methods. One of the best for moss removal is soft washing, which utilizes low-pressure pumps to spray water and chemical cleaners that eliminate moss and algae. Unlike power washing, it avoids high-pressure streams that can damage buildings. Our methods minimize mechanical damage and water infiltration. Many roof manufacturers endorse chemical treatments for effectively killing organic matter like moss without harming the roofing system.

During roof soft washing, we apply a safe bleach solution that reacts with debris. In severe cases, we manually remove moss and organic materials before treatment. A critical step is selecting the appropriate cleaning solution, ensuring minimal environmental impact and protection for your building. We often include an organic-growth retarding treatment to lessen the need for future cleaning.

Roof Cleaning – Treatment

In roof soft washing, we use a safe bleach solution to react with debris. If needed, we manually remove moss and organic materials first. Choosing the right cleaning solution is crucial for minimal environmental impact and building protection. We also use a growth retarding treatment to reduce future cleaning needs.

In the Lower Mainland, we often use soft washing for roof cleaning. This process is not just for aesthetics; many building owners in Vancouver face premature roof replacements due to moss damage. Moss adheres easily to roofs with rough surfaces, causing aesthetic issues and reducing roof lifespan by up to 10 years.

The goal of roof washing is to eliminate organic material without harming the roof system or surrounding plants. Soft wash solutions are essential during this process. What we use tends to require a greater dwell time and often requires additional agitation with a soft brush for the best outcome.
