Soft washing can last from a few months to several years, depending on various factors. Typically, the results last 2-3 years on average, but this can vary based on environmental conditions and the type of surface treated. We have explained the factors that can influence how long soft washing lasts. For instance, if you use a good quality cleaning solution in the soft washing process, the effects can last for several years; otherwise, a few months. So, you must get a professional soft washing treatment by Blueline Pressure Washing.
Surface Type
Porous surfaces like concrete, brick, and stucco tend to hold moisture and organic growth longer, which can reduce the longevity of the cleaning. On the other hand, smoother surfaces like vinyl siding or metal roofs are less prone to rapid regrowth, so they tend to stay clean for longer.
The truth: Soft washing is most effective when the surface allows the cleaning solution to penetrate and kill mold, algae, and mildew at the root. However, rough or textured surfaces may require more frequent cleanings simply because dirt and growth find more places to latch onto. Here’s a rough guideline:
- Vinyl siding: 2–3 years
- Roofing: 3–5 years
- Asphalt shingles: 1–2 years
- Wood siding (painted or stained): 1–1.5 years
- Stucco: 1–2 years
- Cedar shake roofs: 1–1.5 years
Environmental Conditions
Environmental factors may play an integral part in how long soft washing lasts. In warmer climates, dirt and mildew buildup occurs more quickly; rain washes it away quickly. Therefore, you may require soft washing more frequently to keep exterior surfaces in good condition.
- Humid, shady areas (e.g., under tree cover): Algae and mildew can return within 6–12 months.
- Due to salt buildup, coastal regions with salty air may require soft washing every 12–18 months.
- High rainfall areas: Surfaces may stay cleaner between rains, but frequent moisture can lead to quicker organic regrowth—typically requiring treatment every 12–18 months.
- Dry, sunny climates: Due to less organic growth, surfaces can stay clean for 2–3 years.
- Urban areas with pollution: Due to grime and soot buildup, soft washing may be needed every 12–24 months.
Location
Properties surrounded by trees or near wooded areas are especially vulnerable. Falling leaves, sap, and constant shade create the perfect breeding ground for mildew and moss. Similarly, lakeside or riverside homes are exposed to higher humidity levels, increasing the chance of algae and mold buildup. Even urban areas can pose challenges, with pollution and vehicle exhaust coating surfaces in grime faster than usual.
- Here’s how location can affect soft washing frequency:
- Wooded or shaded areas: Every 6–12 months
- Lakeside or riverside properties: Every 12–18 months
- Urban/industrial zones: Every 12–24 months
- Open, sunny areas: Every 2–3 years
Soft washing roofs do not use high pressure and therefore are suitable for various exterior surfaces, including vinyl siding, stucco, brickwork, wood decking, asphalt shingle roofs, and concrete surfaces. Soft washing can even be used to remove moss and mildew growth on roofs!
Benefits of Soft Washing Treatment
Soft wash can safely and effectively remove organic contaminants such as dirt, mildew, moss, mold, and other growths from surfaces without leaving behind unsightly marks or streaks on delicate surfaces like wood siding, shingles, and windows.
Furthermore, unlike a traditional power wash and power wash, which may damage surfaces by leaving behind unsightly streaks or marks, soft wash removes organic contaminants like dirt, mildew, moss, mold, and fungus from these growths without harming them.
Its reduced water pressure requirements make this method safer, more effective, and suitable even for delicate surfaces like wood siding shingles and windows! Regular soft washing sessions will enhance curb appeal and prevent costly damage from mold, mildew, and other biological contaminants that often plague properties.
Is Soft Washing Safe for My Home?
Yes! Soft washing is safe for your house. It uses a specialized system to spray surfactant or foaming agent at low pressure, which penetrates and safely breaks down organic contaminants. Once they’ve had time to work, the cleansing solution is rinsed away using low-pressure water with no risk or residue left behind.
It’s perfect for hard-to-reach exterior surfaces such as roofs, while its refreshing effects on vinyl and wood siding renew their looks. Unlike pressure washers that use a high-pressure stream, soft washing employs a gentle low-pressure stream combined with specialized cleaning solutions to safely and effectively clean surfaces. Soft washing can also be used on decks, fences, and paver materials.
Soft Washing Safety Precautions
Professional soft washing companies take precautions to protect your landscaping and other property features from damage during cleaning processes. Before beginning, they typically cover plants, flowers, and outdoor furniture with plastic sheets.
In addition, they pre-wet any areas that might be sensitive to chemicals used during soft washing services before prepping ladders and tarps to protect the roof against debris falling onto or damaging it during this process.
How Often Should You Soft Wash a Roof?
Soft wash cleaning requires special cleansers that dissolve grime, followed by low-pressure rinsing to rinse away debris without damaging shingles or siding. Properties surrounded by trees often need periodic roof washings to eliminate branches, acorns, and twigs that promote moss and lichen growth on their roofs.
Debris Buildup
As organic debris, such as leaves, branches, twigs, and other organic matter, accumulates on roofs, it prevents water from flowing freely to interior gutters. Over time, this can cause clogs in these systems and structural damage to roofs or houses. Standing water provides an ideal breeding ground for mold growth, which could pose health concerns to residents living nearby.
Environmental Conditions
If you live in an area prone to rainstorms or are surrounded by trees, soft washing your roof may become more frequent. Debris such as branches, twigs, and leaves tend to settle on roofs in such environments, creating the ideal moss and mildew growth conditions.
Age of Roof
Age is integral in how often it’s necessary to soft wash your roof. Older roofs tend to be more vulnerable to damage and debris buildup, so scheduling regular soft washing services to maintain good condition is essential. If you’re uncertain how old your roof is, speaking with its builders could provide additional insights into its history.
As roofs age, their shingles may wear down, leading to leaks and other problems. Therefore, it’s essential that older shingles be regularly checked for wear-and-tear symptoms such as balding shingle edges or surface undulations that indicate your roof needs more frequent cleanings.
Type of Roof
Your roof type plays an essential part in how often it should be soft washed, using low-pressure washing to clear away debris and kill moss, lichen, and algae colonies that threaten its future growth. Soft washing works on asphalt shingles, metal roofs, and tile roofs alike!
Rainfall and dampness in your area can have an adverse effect on the lifespan of your roof, encouraging moss and lichen growth that weakens shingles over time. Regularly inspecting and cleaning your roof will help avoid these spores taking root on its surface, thus lengthening its lifespan and saving money down the line.
