Professional Soft Washing Services in Sacramento

Roof soft washing is a low-pressure cleaning method designed to safely remove organic growth from your roof without using the high pressure associated with traditional power washing. We apply a carefully diluted solution of sodium hypochlorite (SH), water, and surfactant to the roof. The solution works to kill and break down organic growth such as algae, moss, and lichen, which can then be safely rinsed away using low pressure. Our goal is to clean your roof effectively without damaging the shingles, tiles, or other roofing materials.

No. Soft washing is specifically designed to clean roofs without relying on high pressure. We use less than 100 PSI when rinsing the roof. Instead of using pressure to force growth off the roof, our cleaning solution does the majority of the work by killing and breaking down the organic growth. This makes soft washing a much safer method for cleaning roofing materials than high-pressure power washing.

We use low pressure—under 100 PSI. Traditional pressure washing can use significantly higher pressure, which can potentially damage roofing materials. With soft washing, we rely primarily on the cleaning solution rather than pressure. The solution is applied to the affected areas, allowed to work, and then rinsed using controlled low pressure.

Our roof-cleaning solution consists primarily of sodium hypochlorite (SH), water, and surfactant. For roof cleaning, we typically use a 6.25% SH mix. The surfactant helps the solution cling to the roof and organic growth so it can work effectively instead of immediately running off. The cleaning solution is what kills the organic growth, while the low-pressure rinse removes the dead material and residue.

There are three common types of organic growth we encounter on roofs: Algae – Often appears as dark streaks or discoloration on shingles. Moss – Usually appears as green, fuzzy growth and can become thick over time. Lichen – A more stubborn growth that can attach firmly to roofing materials. Our soft-washing process is designed to treat and remove these types of organic growth without relying on aggressive pressure.

Protecting your landscaping is an important part of our process. Before we begin, we thoroughly soak plants and vegetation with water. We continue protecting and watering vegetation throughout the cleaning process and again after the roof has been completed. When necessary, we also cover plants and vegetation located directly underneath the roof’s gutter lines to provide additional protection from runoff. Our preparation and plant-protection process is an important part of every roof soft wash.

We commonly clean: Asphalt shingle roofs Concrete tile roofs Wooden cedar roofs Because different roofing materials require different considerations, we evaluate the roof before beginning the cleaning process and adjust our approach accordingly

The amount of time required depends on the size of the roof, the amount of organic growth, the roofing material, and the accessibility of the roof. Before starting, we inspect the property and determine the appropriate cleaning process. Our preparation, cleaning, rinsing, and plant-protection procedures are all included in the service.

Yes, the basic soft-washing process is very similar, but the chemical concentration is different. For roof cleaning, we typically use a 6.25% SH mix. For house washing, we typically use approximately a 1% SH mix. Both services use low pressure and include similar preparation and protection procedures, including wetting vegetation before cleaning, protecting sensitive areas when necessary, and thoroughly rinsing the property after the cleaning is complete.

The biggest difference is how the cleaning is accomplished. High-pressure washing relies heavily on pressure to remove dirt and organic growth. On a roof, excessive pressure can potentially damage shingles and other roofing materials. Soft washing uses a cleaning solution to kill and break down organic growth, followed by a controlled low-pressure rinse. This allows us to clean the roof effectively while using under 100 PSI, making soft washing a safer and more appropriate cleaning method for many roofing materials.
