Why Cleaning a Cedar Shake or Cedar Roof Is Not a DIY Project

Cedar shake and cedar shingle roofs are known for their natural beauty, durability, and longevity. However, these roofs require regular cleaning and maintenance to prevent damage, extend their lifespan, and maintain their aesthetic appeal. While some homeowners may consider cleaning their cedar roof as a DIY project, it is not recommended. Improper cleaning methods can cause severe damage to the wood, reduce the roof’s lifespan, and even lead to costly repairs. Hiring a professional is always the best approach for maintaining a cedar roof. In this article, we’ll explore why cedar roof cleaning is not a DIY project and why hiring a professional is essential.

1. Risk of Damage from Improper Cleaning Methods

Cedar shakes and shingles are delicate compared to other roofing materials like asphalt or metal. Using the wrong cleaning techniques can cause irreversible damage to the wood.

  • High-Pressure Washing: Many homeowners assume pressure washing is an effective way to clean a cedar roof, but it can erode the wood’s surface, strip away natural oils, and cause premature splitting and cracking.
  • Harsh Chemicals: DIY cleaners may use bleach, ammonia, or other harsh chemicals to remove moss and algae. These substances can weaken the wood fibers, causing them to become brittle and prone to decay.
  • Scrubbing and Abrasive Tools: Scrubbing the roof with hard brushes or abrasive materials can damage the shingles and remove protective layers, making the roof more vulnerable to weather and UV exposure.

Professional cedar roof cleaners use specialized low-pressure washing systems and eco-friendly cleaning solutions to clean the roof safely without harming the wood.

2. Safety Hazards of Roof Cleaning

Cleaning a cedar roof requires climbing onto the roof, often with cleaning solutions and equipment. This poses significant safety risks, especially for those who are not trained in proper roofing safety techniques.

  • Slippery Surfaces: Moss, algae, and wet cedar shakes create a slippery surface that increases the risk of falls.
  • Steep Roof Pitch: Many cedar roofs have a steep slope, making it difficult for untrained individuals to navigate safely.
  • Lack of Proper Safety Equipment: Professionals use harnesses, ladders, and safety gear to prevent falls, while DIYers often lack these essential safety measures.

Falling from a roof can result in serious injury or even be fatal. Hiring a professional ensures that the job is done safely by trained and experienced technicians.

3. Ineffective Cleaning Results

DIY roof cleaning often fails to deliver long-lasting results because homeowners lack access to the specialized equipment and treatments used by professionals.

  • Temporary Fixes: Many DIY solutions only remove surface dirt but do not address underlying issues such as embedded mold, mildew, and fungi growth.
  • Improper Application of Treatments: Professionals apply protective treatments that inhibit moss, algae, and mold growth, ensuring the roof stays clean for longer.
  • Uneven Cleaning: DIYers may miss certain areas, leading to patchy results and allowing moss and algae to regrow quickly.

A professional cleaning service ensures a thorough and even cleaning process that enhances the roof’s longevity and appearance.

4. Voiding the Roof Warranty

Many cedar roofing manufacturers and installers provide warranties that cover the materials and craftsmanship. However, these warranties often have maintenance requirements, including professional cleaning.

  • DIY Cleaning Can Void the Warranty: If the roof is damaged due to improper cleaning methods, the manufacturer or contractor may refuse to cover repairs or replacements.
  • Professionals Follow Manufacturer Guidelines: Hiring a professional ensures that the cleaning process adheres to manufacturer recommendations, keeping your warranty intact.

Investing in professional cedar roof maintenance helps protect your warranty and prevents costly out-of-pocket repairs.

5. Time-Consuming and Labor-Intensive

Cleaning a cedar roof is not only dangerous but also time-consuming. A DIY project requires homeowners to:

  • Research proper cleaning methods and solutions
  • Gather equipment, including ladders, cleaning agents, and safety gear
  • Spend hours on the roof, scrubbing or attempting to apply treatments
  • Clean up debris and runoff afterward

Even after all that effort, the results may still not match the quality of a professional cleaning. Hiring experts saves homeowners time and ensures a superior outcome.

6. Long-Term Cost Savings

Many homeowners believe that DIY cleaning saves money, but in reality, improper cleaning techniques can lead to costly repairs and premature roof replacement.

  • Potential Damage Costs: A damaged cedar roof may require repairs costing thousands of dollars.
  • Frequent Cleaning Needs: DIY cleaning methods often fail to prevent moss and algae regrowth, requiring frequent re-cleaning.
  • Extending Roof Lifespan: Professional cleaning and maintenance extend the life of a cedar roof, preventing premature replacement costs.

Hiring a professional may seem like an upfront expense, but it saves homeowners significant money in the long run.
