What Is Cedar Shake Roofing?
Cedar shake roofs are made from natural cedar wood, typically from Western Red Cedar trees. The wood is split rather than sawn, giving it a rough, textured surface that enhances its rustic charm. Shakes are thicker and more irregular than cedar shingles, which are sawn on both sides.
What Are The Benefits?
Cedar shake roofs offer a multitude of advantages that make them a popular choice for homeowners. Here are the benefits of having a cedar roofing:
Natural Beauty
Cedar shake roofs offer a unique, natural aesthetic that enhances the curb appeal of any home. The rich, warm tones of cedar wood complement a variety of architectural styles, from traditional to modern.
Durability
Cedar is naturally resistant to insects and rot, making it a durable choice for roofing. With proper maintenance, a cedar shake roof will last 30 to 40 years or even longer.
Insulation
Cedar shakes provide excellent insulation, helping to keep your home cool in the summer and warm in the winter. This can lead to energy savings and increased comfort.
Eco-Friendly
Cedar is a renewable resource, and cedar shake roofs are biodegradable. Choosing a cedar shake roof is an environmentally friendly option compared to synthetic roofing materials.
Why Cedar Shake Roofs Attract Lichen, Moss & Algae
Environmental Factors
Cedar shake roofs are particularly vulnerable to lichen, moss, and algae due to their constant exposure to the elements. These organisms thrive in environments where moisture is prevalent, which is often the case with cedar shakes. They actively deteriorate the roofing material by loosening shingle granules, thus exposing underlying asphalt and fiberglass, which reduces the lifespan of the roof.
Factors such as overhanging trees not only provide shade but also trap moisture on the roof, creating an ideal breeding ground for these growths. This happens a lot in homes with fast-growing trees like Eucalyptus that cover parts of the roof. The shingles get damaged and change color over time because of this.
Additionally, the direction a roof faces can significantly affect its susceptibility to these organisms. Some parts of roofs get less sunlight, like the north-west and south-east sides. These areas can hold onto moisture and grow moss and algae more easily.
Material Characteristics
The very nature of cedar as a building material contributes to its challenges with lichen, moss, and algae. While cedar is celebrated for its durability and resistance to decay and insects, it is also a natural product that retains moisture. This characteristic, while generally beneficial for the wood’s longevity, makes it a hospitable environment for unwanted organic growth.
Over time, these organisms break down wood, causing decay and weakening its structure. Regular maintenance and preventive strategies are crucial to mitigate these effects and preserve the longevity of cedar shake roofs.
Understanding the Problem: Lichen, Moss, and Algae on Cedar Shake Roofs
Identifying these common culprits is key to preserving your cedar shake roof:
Characteristics and Differences
Algae, a nonflowering aquatic plant, thrives in humid environments combining heat and moisture, particularly in shady, damp areas beneath large trees. These organisms derive nutrients from limestone fillers commonly found in roofing materials, which accelerates their growth on roofs.
Lichen, a symbiotic relationship between algae and fungus, poses a significant threat by using roots to secure itself to shingles, potentially causing permanent damage if not addressed.
Moss shares similarities with lichen, utilizing rhizoids to anchor itself to shingles, thereby facilitating an environment that supports further growth of algae and lichen. Unlike these, mold presents as black or brown blotches or slimy accumulations and is primarily associated with water-absorbed areas, posing additional health risks due to its growth on damp surfaces.
Symptoms and Signs
Lichens, moss, and algae each manifest distinctively on cedar shake roofs, often causing detrimental effects. Lichens are particularly tenacious and can permanently scar shingle surfaces by forcibly removing the top layer, known as the color coat. They are not easily dislodged by natural elements such as wind or rain, which underscores the importance of timely identification and treatment.
Moss, characterized by its root-like appendages called rhizoids, embeds itself into shingles, creating a thick layer of soil that harbors further growth of algae and lichen. This interlocking system catches windblown dirt, exacerbating the problem and accelerating the degradation of the roof. The forcible removal of moss causes permanent damage to the shingles, necessitating early roof replacement.
Algae, identified by the ugly and damaging stains it leaves, thrive on the moisture and limestone within shingles. It feeds on the limestone filler, gradually depleting the shingle’s mass and its ability to reflect heat, thus increasing attic temperatures and potentially raising air conditioning costs.
Can You Stain or Seal Your Cedar Shake Roof?
Cedar shake roofs are a popular choice for their natural beauty and durability. However, many homeowners wonder if they should stain or seal their cedar shakes to protect them further. While the intention is good, experts generally advise against staining or sealing cedar roofs.
Here’s why:
Cedar’s Natural Weathering Process
Effects of staining a cedar shake roof, with the stain beginning to peel away, revealing the natural wood beneath
Cedar shake roofs are designed to weather naturally over time. As the wood is exposed to the elements, it develops a beautiful silver-gray patina that many find aesthetically pleasing. This weathering process is part of what gives cedar roofs their distinctive look and is a natural result of the wood’s interaction with sunlight and moisture.
Downsides of Staining or Sealing
The stain on the cedar shakes is peeling which leads to moisture being trapped and accelerating roof deterioration
Staining or sealing a cedar roof can actually do more harm than good in the long run. Here are a few reasons why:
- Traps moisture: Sealants and stains create a barrier that prevents the wood from breathing. This can trap moisture inside the shakes, leading to premature rot and decay.
- Accelerates deterioration: The trapped moisture can cause the wood to deteriorate faster, shortening the lifespan of your roof.
- Difficult to maintain: Stains and sealants require regular reapplication as they wear off over time. Neglecting to maintain them can lead to an uneven, patchy appearance.
- Alters the natural look: Stains and sealants can change the natural color and texture of the cedar, detracting from the rustic charm that many homeowners find appealing.
While the urge to protect your cedar shake roof is understandable, staining or sealing is not the answer. Embrace the natural beauty of cedar and its inherent protective qualities. Regular cleaning and proper ventilation are the keys to ensuring your cedar shake roof provides lasting beauty and protection for your home.
Long-Term Maintenance Tips
Proactive care is key to maximizing the lifespan of your cedar shake roof. Here are some tips to take care of your cedar roof:
Tip #1: Conduct regular routine inspections
Homeowners should conduct regular inspections of their cedar shake roofs to identify any potential issues early. It’s advisable to visually check the roof from the ground or use binoculars, and for those with access, an attic window can provide a closer view.
Advanced technology like drones can also be employed for a more thorough inspection, ensuring that homeowners do not walk on the roof, which could lead to damage if the shingles are already compromised. Inspections should focus on identifying damaged shingles or shakes, clearing debris, and checking for signs of moisture or organic growth which accelerate roof decay.
Tip #2: Perform seasonal care and maintenance
Seasonal maintenance is crucial for extending the lifespan of a cedar shake roof. During the fall, homeowners should prepare the roof for winter by removing leaves, twigs, and other debris that may have accumulated, which helps prevent moisture retention and organic growth.
This is also an ideal time to trim overhanging branches to reduce shaded areas where moss and mildew thrive. Before the onset of winter, it’s important to check and repair any damaged shingles to maintain the roof’s structural integrity and prevent water infiltration during the colder months.
Tip #3: Ask for professional help
Hiring professional roofing services can be a cost-effective way to maintain the health of a cedar shake roof. Professionals can inspect, clean, and apply necessary treatments to the roof, addressing any issues before they become major problems.
They are equipped to handle the cleaning and maintenance without causing damage to the cedar shakes, using cedar-friendly solutions that preserve the wood’s natural properties. Additionally, professional services can provide peace of mind by ensuring that the roof is prepared to withstand various weather conditions, from intense UV light in the summer to moisture and cold in the winter.

We use a specially formulated cleaning solution designed to eliminate dirt, moss, algae, mold, and other debris from your cedar shake roof. Our cleaning solution is not only safe for your roof and the environment but also highly effective at eradicating the root cause of these problems: algae spores.
Our team carefully applies this powerful solution to the entire roof, ensuring that every shingle is thoroughly treated. The cleaning solution works by penetrating deep into the cedar shakes to kill algae, mold, and mildew at the source, preventing regrowth. This method is particularly effective at removing moss and algae spores, ensuring that the problem is eliminated and your roof stays cleaner for longer.
By targeting and eradicating these spores, our cleaning solution helps maintain the integrity and appearance of your cedar shake roof, providing a comprehensive clean that lasts.
Step 3: Gentle Cleaning
Using our soft wash method, we gently clean the cedar shakes. This technique ensures that we remove all the grime and buildup without damaging the delicate wood. Unlike pressure washing, which can be too harsh, our soft wash method is perfect for maintaining the integrity of your cedar roof.
Step 4: Rinsing and Final Inspection
After the cleaning solution has done its job, we thoroughly rinse the cedar shake roof to remove any remaining residue.

Structural Upkeep
Maintaining the structural integrity of a cedar shake roof involves regular removal of debris such as leaves, pine needles, and sticks, which retain moisture and promote the growth of wood-destroying fungi. Additionally, it is essential to inspect the roof for cracks and damage, especially after severe weather events.
Wood naturally expands and contracts due to moisture and temperature fluctuations, which can lead to cracks. If these cracks or any signs of damage are observed, homeowners should promptly contact professionals to repair or replace the affected shingles to prevent further deterioration.
Monitoring Growth
Regular inspections are vital to monitor and control the growth of lichens, moss, and algae on the roof. Homeowners should look for excessive growth of these organisms as an indicator of improper drying and potential moisture issues that can support wood-rotting organisms.
Removing overhanging branches that shade the roof and retard drying is a critical preventive strategy. Such proactive measures help maintain the roof’s condition and prevent the need for extensive and costly repairs in the future.
Preventive Strategies
Water Runoff Management
To mitigate water retention and subsequent damage, homeowners should ensure proper water runoff by removing overhanging branches. This action not only decreases the likelihood of fire hazards but also speeds up the drying process of the roof. Additionally, maintaining a clean roof through methods such as soft washing helps eliminate mosses or fungi, thereby preventing potential damage over time.
Ensure Proper Ventilation
Good attic ventilation helps reduce moisture buildup, creating an inhospitable environment for lichen, moss, and algae.
- Install ridge vents and soffit vents
- Ensure existing vents are unobstructed
- Consider adding attic fans for improved air circulation
Clean Gutters Regularly
Regularly clean your roof gutters to prevent water backup and increased moisture on your roof, which can occur when gutters become clogged. It’s best to clean your gutters twice a year. If you have lots of trees near your home, you might need to clean them more often.
To reduce the accumulation of debris and make maintenance easier, consider installing gutter guards. Gutter guards help prevent debris from accumulating in your gutters. This improves the flow of water and protects your cedar shake roof.
Trim Overhanging Branches
Overhanging tree branches can create shade and drop debris, promoting growth of lichen, moss, and algae.
- Trim branches to allow at least 10 feet of clearance above the roof
- Remove dead branches that could potentially fall and damage the roof
Sunlight Exposure and Shading
Exposure to sunlight can lead to photodegradation, where the cedar shake’s lignin decomposes, weakening the roof’s structural integrity. Homeowners should consider professional treatments to protect against UV damage, which prevents the wood from aging prematurely. Areas under constant shade are prone to mold and mildew; therefore, managing the shading by trimming nearby trees reduces these risks.
