Top Signs Your Roof Needs a Professional Wash

Posted on June 10th, 2023

Your roof is one of the most important components of your home's exterior. It not only protects you from the elements but also enhances the overall aesthetic appeal of your property. Over time, however, your roof can accumulate dirt, debris, moss, algae, and other unsightly substances that not only detract from its beauty but also compromise its functionality. In this blog post, we will explore the top signs that indicate your roof is in need of a professional wash. By recognizing these signs early on, you can take proactive steps to maintain the condition and longevity of your roof.

Dark Streaks and Stains

One of the most common signs that your roof requires a professional wash is the presence of dark streaks and stains. These stains are often caused by algae, moss, or lichen growth on your roof's surface. As moisture accumulates on your roof, it creates a conducive environment for these organisms to thrive. Over time, these stains can spread and become more noticeable, detracting from the overall appearance of your home.

In addition to being visually unappealing, these dark streaks and stains can also accelerate the decay of your roofing system. Algae, moss, and lichen have the ability to retain moisture, which can hasten the aging process, promote rot, and potentially result in leaks. By arranging for a professional cleaning service, you can successfully eliminate these stains and proactively safeguard against additional harm, thereby ensuring the durability and effectiveness of your roofing structure.

Visible Moss or Algae Growth

If you notice the presence of moss or algae on your roof, it's a clear indication that a professional wash is needed. Moss and algae can accumulate in areas where moisture is prone to collecting, such as the shaded sections of your roof. These growths not only compromise the visual appeal of your home but can also cause structural damage if left untreated.

Moss, in particular, has root-like structures that can penetrate and loosen the shingles, leading to potential leaks and water damage. Algae, on the other hand, can create a slippery surface, posing safety hazards during rain or snowfall. A professional roof wash will effectively eliminate these growths, protecting the integrity of your roof and ensuring a safer environment for you and your family.

Clogged Gutters and Downspouts

Another sign that your roof is in need of a professional wash is the presence of clogged gutters and downspouts. As debris, leaves, and dirt accumulate on your roof, they can be carried by rainwater into your gutters. Over time, this build-up can obstruct the flow of water, leading to clogged gutters and downspouts.

Clogged gutters pose a significant risk to the overall health and integrity of your home. When gutters become blocked, water can accumulate and find its way back into your property, resulting in water damage, rot, and the growth of mold. Additionally, this excess moisture creates the perfect environment for the proliferation of algae and moss. To prevent potential damage to your home, including the roof, it is essential to schedule a professional gutter cleaning service.

Decreased Energy Efficiency

Believe it or not, a dirty roof can impact the energy efficiency of your home. When moss, algae, and other debris accumulate on your roof, they can create a layer of insulation, trapping heat and causing your home to retain more warmth during the summer months. This can result in increased cooling costs as your air conditioning system works harder to maintain a comfortable temperature.

A professional wash performed on your home's top surface can effectively eliminate these insulating layers, enabling better sunlight reflection and enhancing energy efficiency. By making regular investments in washing the upper exterior of your home, you can effectively lower your energy consumption, reduce utility bills, and create a more comfortable living environment for you and your family.

Roof Age and Warranty Considerations

The age of your roof is an important factor to consider when determining whether it needs a professional wash. As your roof ages, it becomes more susceptible to damage and deterioration caused by dirt, debris, and organic growth. If your roof is nearing the end of its lifespan, a professional wash can help extend its durability and postpone the need for costly roof replacement.

It's also crucial to review the warranty and guidelines provided by your roof manufacturer. Many warranties stipulate the necessity of regular maintenance, which may include professional washing, to uphold the validity of the warranty. By following these guidelines, you can safeguard your warranty coverage and guarantee that your roofing system remains in excellent condition.

Pest Infestations and Damage

A dirty roof can attract pests and lead to potential infestations. Moss, algae, and debris provide a hospitable environment for insects, birds, and rodents to nest and find shelter. These unwanted guests can cause damage to your roof and even find their way into your home, creating further problems.

Pests like birds can cause harm to the uppermost part of your home, resulting in damage to shingles and providing opportunities for water infiltration. Insects, such as termites, are often drawn to moist environments and wooden elements located on the highest point of your property, which can potentially lead to structural problems. Engaging professional cleaning services for this elevated area not only clears away the debris that attracts pests but also eradicates their living spaces, dissuading infestations and safeguarding your property from harm.


Regularly monitoring your roof for signs of dirt, stains, moss, and algae growth is crucial for maintaining its integrity and prolonging its lifespan. If left unaddressed, these issues can lead to structural damage, decreased energy efficiency, and potential leaks.
