Roof Pressure Washing Services

Our roof pressure washing services focus on safely removing dirt, algae, and debris to restore the roof’s appearance and extend its lifespan. We tailor our approach based on roof material and condition, using appropriate tools and techniques designed to protect your property.

What Is Roof Pressure Washing

Roof pressure washing involves using controlled water pressure to eliminate contaminants like moss, algae, mold, and dirt from roofing surfaces. The process improves aesthetics and helps prevent damage caused by biological growth or debris buildup.


We use low to moderate pressure settings, adjusted to avoid harming shingles or tiles. Chemical cleaners may be applied beforehand to soften stains and organic matter, ensuring thorough yet gentle cleaning. Our goal is to clear the roof without causing water intrusion or structural damage.

Types of Roofs We Clean

We clean a variety of roofing materials, including:


  • Asphalt shingles
  • Clay and concrete tiles
  • Metal roofs
  • Wood shake and shingles


Each roof type requires specific handling. For example, asphalt shingles are sensitive to high pressure and need careful treatment, while metal roofs tolerate stronger washing techniques. We assess the material before cleaning to select the safest and most effective method.

Specialized Equipment and Techniques

We use professional-grade pressure washers with adjustable pressure controls and angled nozzles to minimize risk. Soft washing systems allow us to apply cleaning solutions gently when needed.


Our technicians are trained to control water pressure precisely, preventing damage to the roofing components. Safety measures include using extension wands and secure footing equipment to work efficiently without risking structural harm or technician injury.

Benefits of Professional Roof Pressure Washing

Our professional roof pressure washing service provides tangible advantages for both the appearance and durability of your roof. Proper cleaning removes damaging substances and improves the overall condition efficiently and safely.

1.  Enhancing Curb Appeal


A clean roof significantly improves a home's exterior look. Over time, dirt, algae, and moss accumulate, causing dark stains and discoloration that diminish your property's aesthetic.


Our pressure washing removes these stains thoroughly, restoring your roof’s original color and texture. This can make your entire house appear well-maintained and more attractive, which is especially important if you plan to sell or increase property value.


Using professional-grade equipment ensures no damage to shingles or roofing materials during the cleaning process. This method results in a spotless roof without the risks associated with DIY approaches.




2. Prolonging Roof Lifespan


Roof pressure washing eliminates harmful elements such as mold, mildew, and moss that deteriorate roofing materials over time. These substances can trap moisture and cause premature wear, leaks, or structural damage.


By regularly scheduling professional cleanings, we help protect your investment. Removing damaging buildup extends the lifespan of your roof by maintaining its integrity and preventing costly repairs.


Our experienced team uses techniques tailored to your roof type, ensuring effective cleaning without weakening shingles or tiles. We focus on preserving your roof's durability while preventing future issues.

Safety and Environmental Standards

We prioritize careful methods and responsible choices in every roof pressure washing project. Our approach ensures effective cleaning while minimizing impact on your property and the environment.

Eco-Friendly Cleaning Solutions

We use biodegradable, non-toxic cleaning agents that effectively remove dirt, algae, and soot without harming plants, pets, or local water sources. These solutions break down naturally and comply with environmental regulations in Glendale, CA.


Our chemicals avoid harsh acids or bleach, reducing the risk of roof damage or runoff pollution. We carefully measure and apply products to limit excess use. This also protects nearby landscaping from exposure.


By choosing eco-friendly solutions, we protect your home’s structure and the surrounding ecosystem. We remain committed to sustainable practices in every service we offer.

Roof and Property Protection

Before starting, we inspect the roof’s condition to adjust pressure settings, preventing damage to shingles, tiles, or seals. Our trained technicians use soft washing techniques where necessary, combining low pressure with cleaning agents.


We cover and protect nearby fixtures, windows, and outdoor equipment from overspray and debris. Gutters and drainage systems are monitored to avoid clogging or contamination.


Our team follows strict safety protocols to safeguard your property and our crew throughout the process. This approach limits potential complications and extends the life of your roof.

Frequently Asked Questions

 Regular cleaning not only restores curb appeal but also extends the lifespan of your shingles by preventing moisture damage. Below are common questions homeowners in Glendale ask before scheduling roof pressure washing.

  • How often should I have my roof pressure washed in Glendale, CA?

    In Glendale’s warm, wet winters and dry summers, most roofs benefit from pressure washing every 2–3 years to prevent algae and moss growth. If your roof is shaded by large oak or pine trees, consider annual inspections and cleaning to remove leaf debris before it traps moisture against the shingles.

  • Will pressure washing damage my roof shingles?

    When performed by a licensed technician using the correct pressure settings and soft‐wash detergents, roof pressure washing is safe. At Glendale Elite Roofing, we use low‐pressure equipment (typically under 1,200 PSI) and roof‐safe cleaning agents to avoid striping granules or lifting shingles while still eliminating stains and organic buildup.

  • Do you offer a roof inspection before pressure washing?

    Yes. Every service includes a no‐charge safety and condition check. We inspect for cracked or damaged shingles, deteriorating flashing, and potential leaks. If we find any issues, we’ll repair them first to ensure water doesn’t penetrate under the shingles during cleaning.

  • How long does the roof pressure washing process take?

    For a standard single‐family home in Glendale, most roof washing jobs take 2–4 hours from start to finish—including setting up safety harnesses, applying cleaning solution, rinsing, and a final inspection. Larger or steeper roofs may require additional time or a brief follow‐up visit if staining is heavy.

  • Do you carry insurance and offer a satisfaction guarantee for roof pressure washing?

    Yes. Glendale Elite Roofing is fully licensed and insured for both roofing and exterior cleaning. We carry a $2 million general liability policy, and we guarantee you’ll see a noticeable improvement in your roof’s appearance. If you’re not satisfied, we’ll re-treat any missed spots at no extra charge.
