Comprehensive Guide to Roof Cleaning: Debunking Common Myths

Roof cleaning is a crucial aspect of home maintenance that often gets overshadowed by misconceptions. At Dean Roofing Company, we believe in empowering homeowners with accurate information. Let’s debunk some of the most prevalent myths surrounding roof cleaning.

Myth 1: Roof Stains Are Solely Due to Dirt and Pollutants

Contrary to popular belief, while dirt and pollutants can cause staining, moss and algae are usually the primary culprits. These organisms thrive in moist environments. When it rains, algae can form unsightly streaks that can spread across the roof. It’s essential to address these issues promptly to maintain the aesthetic and functional integrity of your roof.

Myth 2: Moss and Algae Are Merely Aesthetic Concerns

This couldn’t be further from the truth. Moss and algae are not just cosmetic issues; they can be highly destructive. They can rapidly consume the limestone present in many asphalt shingles, making the shingles’ outer layer brittle. This can lead to the premature degradation of the shingles, compromising the roof’s longevity.

Myth 3: A Roof Infested with Moss and Algae Requires Replacement

This is a misconception that could cost homeowners significantly. You don’t need an unplanned roof replacement to address moss and algae issues. A professional cleaning by reputable roofing contractors in Clearwater FL, like Dean Roofing Company, can effectively handle the problem, usually within a day. It’s essential to be wary of roofers who might exploit this myth to sell new roofs unnecessarily.

Myth 4: DIY Roof Cleaning is the Way to Go

While the DIY approach might seem tempting, roof cleaning is not a task to be taken lightly. Effective removal of moss and algae requires specific chemicals, which should be applied using specialized tools and with adequate protection. Moreover, climbing onto your roof without proper training and equipment can be perilous. It’s always best to rely on professionals for such tasks.

Myth 5: Cleaning Chemicals Can Harm Your Landscape

A common concern among homeowners is the potential damage cleaning chemicals might cause to their landscape. However, the chemicals used for moss and algae removal are not corrosive. When managed by trusted professionals like Dean Roofing Company, there’s no risk to your home or landscape.

Myth 6: Power Washers Are Suitable for Roof Cleaning

Power washers might be effective for cleaning concrete and brick surfaces, but they’re not recommended for roofs. Using a power washer on a roof can strip the granules from asphalt shingles, removing its protective layer. Instead of safeguarding your roof, you’d be exposing it to potential damage.


Roof cleaning is an integral part of home maintenance. By understanding the myths and realities surrounding it, homeowners can make informed decisions.
