4 Roof Cleaning Myths and the Truth Behind Them



Maintaining a clean roof is not typically a priority for most homeowners. Once the roof is installed, the common belief is that it requires minimal attention unless there is noticeable damage. However, this perspective can be quite dangerous. Like other aspects of homeownership, regular care and inspection of the roofing system are crucial. Additionally, occasional proper cleaning can greatly benefit the roof. Several misconceptions surround roof cleaning, and it’s important to separate fact from fiction. Below are four myths and the truth about roof maintenance. Be sure to speak with the professional roofing services at Shull Remodeling in Emporia for assistance with any repairs to your roofing system.

MYTH: Stains on roofs are caused by dirt and grime alone.

FACT: Contrary to popular belief, the most common stains on roofs are not solely the result of dirt and grime. In fact, a significant cause of stains is a type of algae called gloeocapsa magma. This algae thrives on the calcium carbonate found in limestone and moisture accumulated on shingles. As the algae grow, it manifests as dark streaks on the rooftop. These streaks are often mistaken for dirt, but they are actually signs of algae growth. It’s important to note that these algae can cause damage to the shingles and shorten the lifespan of the roof.

MYTH: Moss is a harmless and common occurrence on roofs.

FACT: Moss tends to thrive in cool and damp environments. If you spot moss on your roof, it is likely in an area shaded by trees or other structures. Moss absorbs water through its leaves, acting like a sponge. If left unaddressed, it can continue to absorb rainwater, grow, and spread across the entire roof. Moss tends to grow in between shingles where moisture can accumulate, leading to decay in the roofing structure. Therefore, the presence of moss should be promptly addressed through proper cleaning to restore the roof’s integrity and longevity.

MYTH: Homeowners can easily clean roofs by power washing them.

FACT: While YouTube may provide numerous tutorials for ambitious DIY enthusiasts, power washing a roof is not a task homeowners should undertake lightly. Many well-intentioned homeowners have attempted this cleaning method, only to loosen and dislodge shingle granules or even lose shingles altogether. Furthermore, power washing a roof without proper training and safety precautions can be hazardous. Slippery surfaces can lead to falls and potential injuries. It is advisable to entrust roof cleaning to professional contractors who possess the expertise and knowledge to perform the task safely.

MYTH: Roof cleaning is a waste of money and a marketing ploy used by contractors.

FACT: As previously mentioned, occasional roof cleaning is essential for optimal performance and longevity. Generally, roofs require cleaning every three to six years. The costs associated with roof cleaning may vary among different companies, so it’s always advisable to consult with roofing contractors regarding their preferred cleaning methods and associated charges. Investing in roof cleaning protects the initial investment made during the roof installation process. By having your roof honestly inspected and cleaned when necessary, you can safeguard your investment and extend the roof’s lifespan. 

It is crucial for homeowners in Emporia to dispel common myths surrounding roof cleaning. Regular cleaning and maintenance are necessary to ensure the roof’s longevity and performance. Stains caused by algae, the harmful effects of moss growth, the hazards of improper power washing, and the value of professional roof cleaning services should all be considered. By adopting a proactive approach to roof care and enlisting the expertise of reputable contractors, such as Shull Remodeling, homeowners can safeguard their investment and enjoy a durable and reliable roof for years to come.
