Thorough Inspection

We begin by conducting a comprehensive inspection of your roof to identify areas affected by moss, algae, stains, or dirt. This evaluation allows us to tailor our cleaning approach to the unique needs of your roof.

Gentle Softwash Cleaning

We employ the gentle softwash method, which is low-pressure water and a proprietary blend of cleaners. This effective yet delicate technique removes contaminants without causing any harm to your roofing materials.

Final Inspection

We conclude the process with a thorough rinse to remove any remaining cleansers and debris. A final inspection ensures that your roof meets our high standards of cleanliness and integrity.

Roof cleaning that starts with the material

Moss, algae, lichen, and trapped debris do not affect every roof in the same way. Asphalt shingles, metal panels, cedar shake, and tile each require a material-appropriate assessment. A+ Exterior Cleaning evaluates visible wear, access, drainage, nearby landscaping, and the extent of organic growth before recommending a cleaning approach.

Roof materialOur methodWhat we never do
Asphalt shingleSoft wash (detergent lift + low-pressure rinse)Pressure washing — strips granules, shortens wear-life
MetalSoft wash or controlled low-pressure rinseAbrasives / high PSI on factory coatings
Cedar shakeWood-safe soft wash, fan rinse, gentle pressureAny direct high pressure — splits shakes
TileSoft wash with runoff controlFree walking / high pressure — cracks tiles

When to schedule a roof assessment

Consider an assessment when you notice expanding green patches, dark streaks, debris collecting in valleys, blocked drainage, or growth beneath overhanging trees. North-facing and shaded roof sections often stay damp longer in the Willamette Valley. Cleaning addresses organic buildup, but it does not repair loose roofing, damaged flashing, leaks, or structural problems. Those conditions should be evaluated by a qualified roofer.

What a careful cleaning process includes

  • Identify the roof material and document visible concerns.
  • Select a low-pressure process that fits the surface and its condition.
  • Plan access, runoff management, and protection for appropriate surrounding areas.
  • Set realistic expectations for growth that may release gradually after treatment.
  • Review drainage and recommend related maintenance when needed.

Roof edges and drainage work together, so homeowners may also want to review our gutter cleaning service. For a property-specific recommendation, request a free estimate.

Frequently Asked Questions

Is low-pressure roof cleaning appropriate for asphalt shingles?

Low-pressure treatment can be appropriate for many asphalt shingle roofs when the process matches the roof’s condition and manufacturer guidance. The provider should inspect existing wear, avoid aggressive pressure or scraping, and explain the treatment, runoff controls, and expected results before work begins.

How often should a roof be inspected for moss in the Willamette Valley?

Inspect the roof periodically and after major storms, with particular attention to shaded slopes, roof valleys, and areas beneath trees. Cleaning frequency depends on roof material, orientation, drainage, tree cover, and visible growth rather than a fixed schedule for every property.

The Hidden Dangers of Debris and Algae on Your Roof

When it comes to maintaining your home, the roof is often overlooked—until problems arise. Yet, the hidden dangers lurking there can lead to costly repairs if not addressed. Let’s dive into how debris and algae can silently wreak havoc on your roof and what you can do about it. Types of Debris: More Harmful Than They Appear At first glance, the leaves, branches, dirt, and dust that gather on your roof may seem harmless. However, these nuisances can block water flow, trap moisture, and speed up material degradation. Over time, this accumulation can become a significant threat to your roof’s health. Algae and Moss Growth: More Than Just an Eyesore The moisture trapped by debris creates the perfect environment for algae and moss to thrive. These organisms not only cause unattractive streaks that diminish your home’s curb appeal but also penetrate roofing materials. This can lead to soft spots, making your roof more vulnerable to leaks and further damage. Long-Term Damage: The Silent Destroyer Beyond cosmetic issues, the presence of debris and algae compromises your roof’s structural integrity. Repeated buildup over time can cause irreversible damage, necessitating extensive repairs or even a complete roof replacement. Ignoring these issues could lead to a hefty bill that far exceeds the cost of regular maintenance. Health Hazards of Neglecting Your Roof Your roof might not be the first place you think of when it comes to health and safety, but ignoring its cleanliness can lead to serious issues. Here’s why keeping your roof clean is essential for a healthy home environment: Mold and Mildew: Unseen Invaders When moisture lingers on a dirty roof, it creates a perfect breeding ground for mold and mildew. These fungi don’t just stay outside; they can infiltrate your home, wreaking havoc on indoor air quality. For those with allergies or asthma, mold can be a nightmare, aggravating respiratory problems and making day-to-day living uncomfortable. Pest Magnet A neglected roof can become a haven for pests such as rodents, birds, and insects. These unwelcome guests often find refuge in gutters or soft spots, and from there, they can venture into other parts of your home. Not only do they cause structural damage, but they also pose health risks with their droppings and nesting materials. Health Risks You Can’t Ignore The combination of mold, mildew, and pest activity can severely compromise air quality, posing significant health risks. Children, the elderly, and those with pre-existing respiratory conditions are particularly vulnerable. Poor air quality can lead to chronic health issues, emphasizing the importance of regular roof maintenance.

Tips for choosing the right roof cleaning service

When it comes to taking care of your home, the roof is one of the most important areas that require attention. Regular maintenance and cleaning of your roof will add years to its overall life span and ensure that it is structurally sound. However, a task as demanding and potentially hazardous as roof cleaning requires an expert hand to ensure its proper execution. Choosing the right roof cleaning service, therefore, becomes nothing less than a matter of vital importance for homeowners. One of the most crucial things to check before hiring a roof cleaning service is their certifications. Professional cleaners who have obtained certifications from the National Roofing Contractors Association (NRCA) or the Roof Cleaning Institute of America (RCIA) are ideal partners. Certifications help to ensure that the cleaning service you hire fully understands the complexities of the job and will carry out the task to a high standard. Other essential factors to consider include insurance, as roof cleaning is a potentially hazardous job, and customer reviews to get a sense of previous client satisfaction. A reliable roof cleaning service should be fully insured, and the reviews from previous clients should be positive and encourage trust in the business. Taking the time to research and identify a reputable roof cleaning service provider will help you ensure your home is well-maintained and well-cared for; ultimately, this can save you money and unnecessary stress in the long run. In conclusion, investing in roof cleaning  is essential for maintaining the structural integrity and aesthetic appeal of your home. Regular roof cleaning can prevent potential damage, save you from costly repairs, and prolong the lifespan of your roof. By using eco-friendly products and techniques, a reputable roof cleaning service can ensure that your roof is cleaned effectively without harming the environment. When choosing a roof cleaning service, it is vital to consider their certifications, insurance, and customer reviews to ensure you are investing in a reliable and trustworthy company. With proper maintenance and regular roof cleaning, homeowners can enjoy a spotless and well-maintained roof for many years to come, making it a worthy investment for any homeowner.  So don’t hesitate to reach out to a professional roof cleaning service near you to experience the benefits and value of a clean and well-maintained roof.

The Consequences of Ignoring Roof Cleaning

Maintaining a clean roof is more than just an aesthetic choice; it’s crucial for the overall health of your home. Ignoring roof cleaning can lead to several significant issues, affecting both your property and your wallet. Structural Damage  Over time, debris and algae can accumulate on your roof, threatening its structural integrity. When gutters become clogged, water can pool, eventually seeping into the underlayment. This moisture intrusion leads to leaks, mold growth, and, ultimately, compromised foundations. Regular cleaning helps prevent these problems, ensuring the longevity and sturdiness of your roof. Increased Repair Costs  Investing in routine roof cleaning services can save you a substantial amount on repairs. Studies show that homeowners who prioritize this maintenance spend 50–60% less on repair costs throughout the roof’s lifespan. Without regular cleaning, you might face costly restorations, such as shingle replacements or extensive water damage repairs. These issues are not only expensive but can be easily avoided with a proactive approach to roof care. Decreased Home Value  A neglected roof can diminish your home’s curb appeal and market value. Potential buyers often view a dirty or poorly maintained roof as a red flag, leading to lower offers or a lack of interest. By keeping your roof clean, you enhance your home’s appearance and maintain its value, making it more attractive to prospective buyers.
