Why should I clean my roof?

Over time, dirt, moss, and algae can accumulate on your roof, creating a thick green layer over your tiles. To prevent dampness and maintain an effective roof with proper water runoff, it’s essential to keep your roof clean and well-maintained. We suggest having your roof cleaned every three to five years, adjusting the frequency based on the rate of moss and lichen growth. Homes near large trees or shaded areas may require more frequent cleaning to ensure optimal roof condition.

Roof cleaning methods

There are various methods for cleaning a roof, each with its own set of pros and cons. Here are the five most commonly used techniques for removing moss from roofs.

Manual scraping

A straightforward yet highly effective method for cleaning roof tiles is to manually scrape off the moss, algae, and dirt by hand.

Roof Pressure Washing

Numerous roof pressure washing companies are available to clean your roof, often offering the most budget-friendly option. However, it’s important to note that this method is also the most prone to causing damage.

Softwashing / Bleach

Bleach is often applied following a manual scrape of the roof to provide an immediate clean appearance. However, the main concern with softwashing is the airborne sodium hypochlorite (bleach). As the softwash solution is sprayed onto the roof, particles can be carried by the wind, landing on unintended surfaces. If this chemical contacts any surface other than the roof, it has the potential to cause irreversible damage. When done correctly, softwashing can deliver a uniformly clean result, visible on the same day as the removal of roof moss.

Roof Steam Cleaning

Steam cleaning can be a safe option for certain types of roof tiles. We evaluate your roof to determine the most suitable cleaning method. When steam cleaning, we use very low pressure and a low flow rate, typically around 6-10 liters per minute, heated to approximately 140 degrees. This method leaves your roof beautifully clean immediately after the cleaning process is completed.

Biocidal Roof Wash

Manual roof moss removal followed by a biocidal roof wash offers a gentle and long-lasting solution to remove the cleaning your roof. First, we manually scrape off the roof moss from your tiles. Then, we apply a biocidal roof wash, which effectively eliminates any remaining living organisms, including moss spores and lichen. Over the next 3 to 6 months, your roof tiles gradually return to their original color as the surface dirt is lifted by the biocide and weathering. Additionally, the biocide acts as a repellent, preventing future moss growth for 5 to 10 years or even longer in some cases.
