When is Soft Washing NOT an Option?

Soft washing is a cleaning method that utilizes a low-pressure washing system and specialized solutions to safely remove mildew, bacteria, algae, and other organic stains from roofs and building exteriors. Unlike traditional pressure washing, soft washing is gentle and less damaging to roofing materials. This article explores the benefits of soft washing and provides valuable insights into when it may not be appropriate for certain roofs.

The Data

Soft washing has gained popularity as a highly effective method for cleaning roofs and building exteriors. By utilizing a low-pressure washing system and specialized cleaning solutions, soft washing can effectively eliminate organic stains, leaving surfaces clean and restored. It is particularly beneficial for roofs as it minimizes the risk of damage to roofing materials. However, there are instances where soft washing may not be san option due to the condition of the roof.

Let’s explore ten visual and physical signs that could suggest a roof is too far gone to be soft washed.

Extensive Moss and Algae Growth

Moss and algae growth not only detract from the aesthetic appeal of a roof but can also lead to potential water damage. While soft washing can effectively remove these stains, extensive growth may indicate a more severe underlying issue.

In such cases, soft washing could dislodge loosened shingles, causing further damage. Regular inspection and cleaning, along with preventative maintenance, can help prevent extensive moss or algae growth.

Multiple Leaks

If your roof has multiple leaks, soft washing may exacerbate the problem. Water can seep through these leaks into the home, resulting in significant damage.

It is crucial to address these leaks before considering any kind of washing. Neglected maintenance often leads to multiple leaks, and they should be repaired promptly to ensure the roof’s integrity.

Extensive Granule Loss

Asphalt shingles are protected by tiny granules that provide resistance to UV light and enhance fire resistance. If a substantial amount of granules is found in the gutters, it may indicate that the roof is nearing the end of its life span.

Soft washing, in this case, could dislodge more granules, further exposing the shingles to damage. Regular inspections, gentle cleaning methods, and appropriate maintenance can help prevent excessive granule loss.

Bald Spots on Shingles

Bald spots on shingles are another sign of granule loss. Large bald spots indicate that the roof is likely too old or damaged for soft washing. These bald spots should be prevented through regular maintenance and gentle cleaning methods, ensuring the longevity of the roof.

Damaged or Missing Shingles

Damaged or missing shingles are clear indications that the roof may not be suitable for soft washing. The washing process could further damage these areas and compromise the roof’s integrity. Regular roof inspections and the timely replacement of damaged or missing shingles can help prevent this problem.

Rotting Wood

If the roof structure or sheathing is rotting, any kind of washing is ill-advised as it could lead to further water damage. It is essential to address and fix any signs of rot promptly. Ensuring adequate roof ventilation and attending to leaks promptly can help prevent rotting wood and subsequent damage.

Sagging Roof Deck

A sagging roof deck indicates severe water damage. Washing a sagging roof can worsen the problem and potentially compromise the safety of the entire structure. Regular maintenance and prompt repairs are essential in preventing a sagging roof deck.

Cracked or Blistered Shingles

Cracked or blistered shingles are signs that a roof is nearing the end of its life span. Soft washing may penetrate the cracks or exacerbate the blistered areas, leading to further damage. To prevent such issues, ensuring proper roof ventilation is crucial.

Severe Weathering

Severe weathering weakens a roof’s structure, making it unsuitable for soft washing. Harsh climates can accelerate the deterioration process. Regular maintenance, the use of weather-resistant roofing materials, and periodic inspections are key to preventing severe weathering.

Age of the Roof

If a roof is nearing or beyond its expected lifespan, typically 20-25 years for asphalt shingles, it may be too worn for safe soft washing. Regular roof replacements or overhauls, as recommended by roofing professionals, can help maintain the roof’s condition and prolong its lifespan.

Remember, soft washing is primarily a preventative maintenance task, designed for roofs that are fundamentally sound but require cleaning to remove algae, moss, or other contaminants.

If your roof exhibits any of the issues mentioned above, it may be time to consult a professional for repair or replacement.

Always ensure your roof is in good repair before performing any kind of cleaning or maintenance.


Soft washing offers an effective and gentle solution for removing organic stains from roofs and building exteriors.

By employing a low-pressure washing system and specialized cleaning solutions, it ensures minimal damage to roofing materials. However, it is important to recognize the signs that indicate when soft washing may not be suitable.

Regular inspections, preventative maintenance, and prompt repairs are crucial in maintaining a roof’s integrity and preventing further damage. Consult a professional if you have concerns about your roof’s condition.
