4 Common Roof Cleaning Myths (And The Truth Behind Them)

by | Nov 7, 2023 | Blog, Palm Coast, Roof Cleaning Facts, Roof Cleaning Myths, Roof Maintenance Tips | 0 comments

Many feel the need to clean a roof is unnecessary work. Won’t the rain just clean off my roof? What could be on the roof that would need cleaning? It is wise to reconsider the task of cleaning a roof because not only does it offer the chance to review the condition of the roof, but to remove any residue or gunk. There are several myths associated with roof cleaning

MYTH: Stains are only caused by dirt and grime.

FACT: Roof stains usually come from an alga called gloeocapsa magma, which feeds on the calcium carbonate in limestone and moisture on shingles. As it grows, it creates dark streaks on the roof, often mistaken for dirt. Gravity and rainwater make the algae streak down the slope, potentially damaging shingles and shortening the roof’s lifespan. It is necessary to clean off this alga when spotted to elongate the length of the shingles.   

MYTH: Moss is common on a roof and doesn’t cause any harm.

FACT: Moss thrives in cool and damp environments, particularly in shaded areas like those beneath trees or structures. If you spot moss on your roof, it’s likely in a spot that doesn’t receive much sunlight. Moss acts like a sponge, absorbing water and retaining it. As it grows, it can lift and loosen shingles, creating more room for further moss development. This retaining of water can be for extended periods, leading to potential decay of the roofing structure over time. If left unaddressed, it can continue soaking up rainwater, spreading across the entire roof.

Addressing moss promptly is crucial. Through proper cleaning, the roof can be restored, ensuring its longevity for years to come.

MYTH: A homeowner can easily power wash the roof to clean it.

FACT:  While YouTube is a valuable resource for many DIY home projects, power washing a roof isn’t recommended for the ambitious do-it-yourselfer. Some enthusiastic homeowners have attempted this cleaning project, only to loosen and dislodge the granules on the shingles or even lose entire shingles.

Furthermore, power washing a roof can be a risky technique. For the untrained homeowner, a wet surface may lead to slips and falls, creating potential health concerns. It’s advisable to rely on the expertise of a professional commercial roofing contractor who is familiar with proper procedures and can ensure a safe cleaning process.

MYTH: Roof cleaning is just a waste of money and a gimmick used by roofing contractors.

FACT:  This is a common myth and one to be disputed. As noted above, periodic roof cleaning is crucial for maintaining optimal performance. Typically, a thorough cleaning is necessary every three to six years to ensure the roof’s effectiveness. It’s recommended to discuss the cleaning method and associated costs with the roofing contractor, as charges may vary between companies.

As pointed out through these various myths, preserving your roofing investment requires proactive measures, and regular cleanings play a pivotal role in this endeavor. By subjecting your roof to honest inspections and addressing any cleaning needs promptly, you’re not just maintaining its visual appeal but also enhancing its longevity.
