Navigating the Soft Wash Roof Cleaning Cost: How much does it cost to clean a roof

soft wash roof cleaning cost


Roofs, as an integral part of our homes and businesses, require regular maintenance to keep them in top condition. One such key maintenance task is roof cleaning, and one of the most popular and effective methods is the soft wash. However, understanding the soft wash roof cleaning  cost can be challenging due to the varying factors that influence it. This comprehensive guide aims to simplify the process and help you navigate through the expenses effectively.

Understanding the Concept of Soft Wash Roof Cleaning

Before we delve into the cost, let’s first understand what softwash roof cleaning is and why it’s essential.

Soft wash is a gentler cleaning method compared to its high-pressure counterparts. It relies on a cleaning solution to break down dirt, algae, and moss rather than using high-pressure water. This method is not only gentler on your roof material but is also effective at roof moss removal, extending the life of your roof and making it look new again.

Factors Influencing the Soft Roof Washing Cost

Several factors affect the cost of cleaning your roof using the soft wash method. These include the size of your roof, the type of roofing material, the extent of the cleaning required, and the cleaning service you choose.

Size of Your Roof

Naturally, the larger your roof, the higher the roof cleaning cost. This is because more cleaning solutions and manpower are needed for larger roofs.

Type of Roofing Material

Different types of roof materials react differently to cleaning methods. Some materials may require a stronger cleaning solution, while others require gentler soft washing. For example, asphalt shingles might require a different approach than clay tiles.

Extent of Cleaning Required

The extent of dirt, algae, moss, or any other infestation on your roof can influence the cost. A heavily infested roof may require more intensive cleaning and a higher cost.

Choice of Cleaning Service

Professional roof cleaning services have varying washing prices. The service’s reputation, experience, and guarantees could affect its pricing.

Average Cost for Soft Wash Roof Cleaning

While providing an exact number is challenging due to the abovementioned factors, the average cost to clean roofs using the soft wash method typically ranges from $250 to $600 for a single-family home. However, for larger commercial properties or particularly complex or dirty roofs, this price could go up.

How Often Should You Clean Your Roof?

Determining the frequency of roof cleaning depends largely on the environmental conditions in your area. In regions prone to heavy rainfall and humidity, it’s advisable to clean your roof at least once a year to prevent the growth of moss, algae, and mould. For drier climates, a biennial cleaning might suffice. However, if you notice visible debris buildup or staining, it’s essential to clean your roof promptly to prevent any potential damage. Regular inspections can help you identify the right timing for cleaning and ensure your roof’s longevity.

Why You Should Hire a Professional

While some homeowners might be tempted to try to clean their roofs themselves to save on roof cleaning prices, hiring a professional is usually the best route. Professionals have the experience and the tools to do the job safely and effectively. They can also recognize the best cleaning method for your specific type of roof, ensuring no damage occurs during the cleaning process.

The Impact of Regular Cleaning on Roof Life

Regular cleaning can significantly impact the life of your roof. Removing harmful substances like moss and algae prevents them from eating away at your roofing material, causing it to deteriorate prematurely. Regular cleaning also keeps your roof looking its best, enhancing the curb appeal of your home or business.

The Verdict on Soft Wash Roof Cleaning Cost

In conclusion, while the soft-wash roof cleaning cost can vary, it is often a worthwhile investment. Not only does it help maintain the aesthetic appeal of your property, but it also plays a critical role in extending the life of your roof. By considering factors like the size of your roof, the type of roofing material, and the extent of cleaning required, you can make an informed decision about the potential costs involved.

What can I say? Bruce and Keith provided an exceptional service, and they are really nice guys too. Found out at the last minute they were in Minneapolis, and they fit me in for a cedar shake roof cleaning the next evening after their regular job was done. Even cleaned up my gutters, small fence, and small deck at no charge. The place looks outstanding! Highly recommended.

I highly recommend this business. Due to the work performed we are going to get another 10-14 years out of our cedar shake roof. We were told by some roofing companies that the roof should be replaced in 2 years. I lucked out and found Sullivan Roof Cleaning while researching companies that perform this service, and was pleased to learn that the company does work outside of Iowa. If you need your cedar shakes cleaned, go with Sullivan Roof Cleaning.

Cedar shakes are organic. Though a resilient material. Being organic they need to be maintained. Over time, like any organic material that are subjected to weather elements, they reach a stage of deterioration. Like UV exposure, moisture and seasonal changes. Which results in moss, mold, mildew, lichen and brown rot fungi. These infestations need to be removed to further preserve the integrity of the cedar shake.
The proper way to clean a cedar shake roof is from a ladder. By spraying a special formulated solution onto the shakes and then rinsed with a garden hose pressure. Best done by a professional cedar shake roof cleaner. Not DIY recommended.
No. Pressure washer will require walking on the shakes, which will harm them, and even at its lowest setting will also damage the shakes.
On average, cedar shakes should be cleaned every 10 ten years. Subjective to the grade of the shakes and the amount of surrounding tree cover.
Avoiding walking on a cedar shake roof, other than for repairs.
Never seal a cedar shake roof. Cedar shakes need to breathe. They expand and contract in rain conditions. Seal will shorten the lifespan, to the point of premature replacement.
Staining has no real preserve value and can also harm the integrity of shakes, as stated, they need to be able to breathe. Also, if the shakes are not properly cleaned staining can seal the deteriorating infestation within the shakes.
Depending on the grade of the shakes and installation, and if maintained properly, 40 to 60 years.
