The Safest Way to Clean Delicate Roof Materials Like Cedar Shake

A cedar shake roof offers a rustic, timeless beauty that few other materials can match. Its natural tones and rugged texture bring a unique character to any home. However, this classic appeal comes with a responsibility. Delicate roof materials like cedar shake require specialized care to maintain their integrity and appearance. Without proper cleaning, they can fall victim to moss, algae, and decay, which can shorten their lifespan and lead to costly repairs.

This guide will explain the safest and most effective methods for cleaning your cedar shake roof. We will cover the risks of improper cleaning roof techniques, provide a step-by-step process for safe cleaning, and compare the pros and cons of DIY versus professional services. Understanding the correct approach will not only preserve your roof’s beauty but also protect your investment for years to come.

The Risks of Improper Roof Cleaning

Cleaning a delicate roof isn’t as simple as grabbing a pressure washer and blasting away the grime. Using the wrong methods or tools can cause irreversible damage, turning a well-intentioned cleaning session into a home improvement disaster. Understanding these risks is the first step toward protecting your cedar shake roof.

High-Pressure Washing Damage

The most common mistake homeowners make is using a high-pressure washer. While effective for cleaning concrete driveways, the intense force of a pressure washer can be devastating to cedar shakes. The high-pressure water stream can strip away the natural protective oils in the wood, making it more susceptible to sun damage and rot. It can also gouge the wood, lift or crack the shakes, and force water underneath them. This trapped moisture creates a perfect environment for mold and mildew to thrive, leading to accelerated decay from the inside out. In short, pressure washing can drastically reduce your roof’s lifespan.

Harsh Chemical Damage

Another significant risk comes from using harsh chemicals like bleach or ammonia-based cleaners. These aggressive substances can do more harm than good. Bleach can dry out the wood, causing it to become brittle and prone to cracking. It also breaks down the lignin—the natural “glue” that holds the wood fibers together—weakening the structural integrity of the shakes. Furthermore, these chemicals can discolor the cedar, leaving behind unsightly blotches and streaks that ruin its natural aesthetic. Runoff from these chemicals can also damage your home’s siding, kill surrounding plants, and contaminate the soil.

Physical Damage from Foot Traffic

Simply walking on a cedar shake roof incorrectly can cause significant damage. Cedar becomes more brittle with age and can easily crack or split under concentrated weight. If you’re not trained to walk on delicate roofing surfaces, you could inadvertently break shakes, leading to leaks and the need for expensive replacements. Professional roof cleaners are trained to distribute their weight properly and use specialized equipment to navigate the roof safely without causing harm.

These risks highlight why a careful, knowledgeable approach is essential. A botched cleaning job can lead to more than just cosmetic issues; it can compromise your entire roofing system.

A Safer Approach: Soft Washing with A+ Exterior Cleaning

Given the delicate nature of cedar shakes, a gentler yet effective cleaning method is required. This is where soft washing comes in. A+ Exterior Cleaning specializes in this advanced technique, which is designed to clean sensitive surfaces without the risk of damage associated with high-pressure methods.

Soft washing is a low-pressure cleaning process that relies on specially formulated, biodegradable cleaning solutions to do the work. Instead of blasting away dirt and organic growth, the system applies a cleaning agent at a pressure similar to that of a garden hose. This solution penetrates the surface of the cedar shakes, breaking down moss, algae, mold, and mildew at the root. After the solution has had time to work, it’s gently rinsed away with low-pressure water, carrying all the grime with it.

The primary advantage of this method is its safety. By avoiding high pressure, there is no risk of gouging the wood, lifting shingles, or forcing water into the underlying structure. The eco-friendly cleaning agents are tough on organic growth but gentle on your roof and the surrounding environment. This process not only cleans your roof but also sanitizes it, helping to prevent the rapid return of unsightly and damaging growth.

The Professional Cleaning Process for Cedar Shake

When you hire a professional service like A+ Exterior Cleaning, you’re not just paying for a clean roof; you’re investing in a systematic process designed for safety and longevity. Here’s a step-by-step look at how professionals safely clean a cedar shake roof.

Step 1: Thorough Roof Inspection

The process begins with a comprehensive inspection. A trained technician will assess the overall condition of your roof, identifying areas with heavy organic growth, pre-existing damage like cracked or missing shakes, and potential problem spots around flashing, chimneys, and vents. This initial assessment is crucial for creating a tailored cleaning plan and ensuring that no existing issues are overlooked or worsened during the cleaning process.

Step 2: Site Preparation

Before any cleaning begins, the team prepares the surrounding area to protect your property. This involves:

• Covering Landscaping: Shrubs, flower beds, and other delicate plants near the house are covered with tarps to shield them from cleaning solutions and runoff.
• Wetting Surfaces: Siding, windows, and decks are pre-rinsed with water. This prevents the cleaning solutions from drying on these surfaces and causing streaks or spots.
• Managing Runoff: Gutter downspouts are often disconnected or redirected to ensure that the runoff is managed properly and doesn’t pool in unwanted areas.

Step 3: Application of Cleaning Solution

Using specialized soft washing equipment, a proprietary blend of biodegradable cleaning solutions is applied to the roof. The pressure used is very low—typically no more than 60-80 PSI—which is just enough to deliver the solution without causing any physical impact on the shakes. The formula is designed to kill moss, algae, lichen, and mildew on contact, breaking down their root systems.

Step 4: Dwell Time

After application, the cleaning solution is left to “dwell” on the roof for a specific period. This dwell time allows the active ingredients to penetrate deep into the organic matter and the pores of the wood, lifting dirt and neutralizing biological contaminants. The technician monitors the process to ensure the solution is working effectively without drying out.

Step 5: Gentle Rinsing

Once the dwell time is complete, the roof is thoroughly rinsed with clean, low-pressure water. This gentle rinse washes away the cleaning solution along with all the loosened dirt, dead organic growth, and grime. The result is a clean, sanitized surface that looks refreshed without having been subjected to any damaging force.

Step 6: Post-Cleaning Inspection and Cleanup

The final step is a post-cleaning roof inspection to ensure every part of the roof has been cleaned effectively and no new damage has occurred. The team then removes all protective coverings, rinses down the house and landscaping one last time, and ensures your property is left in the same—or better—condition than when they arrived.

DIY vs. Professional Cleaning: A Cost-Benefit Analysis

For many homeowners, the temptation to tackle home maintenance tasks themselves is strong. However, when it comes to cleaning a delicate cedar shake roof, it’s important to weigh the pros and cons carefully.
