Cedar shake roofing represents one of the most classic and aesthetically pleasing choices for homeowners seeking a natural, rustic look for their homes. For centuries, cedar wood has been prized for its durability, insulation properties, and unique character. Unlike uniform manufactured materials, each cedar shake is distinct, giving a roof a textured, organic appearance that evolves beautifully over time. This guide delves deep into the world of cedar shake roofing, exploring its benefits, drawbacks, installation process, maintenance requirements, and how it compares to other roofing materials, providing you with the essential knowledge to determine if it’s the right choice for your home.
The appeal of cedar shake roofing is immediately visible. It offers a depth and dimensionality that flat asphalt shingles cannot match. The natural grain, subtle color variations ranging from light amber to rich reddish-brown, and the soft, irregular surface create a roof that is as much a work of art as it is a functional component of the house. This style is particularly well-suited for traditional, Craftsman, Cape Cod, and rustic architectural designs, though it can add striking character to modern homes as well. Beyond mere aesthetics, a cedar roof blends harmoniously with natural surroundings, making it a popular choice for homes in wooded or rural settings.
So, what exactly are the advantages of investing in a cedar shake roof?
- Superior Insulation: Cedar is a natural insulator. The air pockets within the wood’s cellular structure help regulate attic temperature, keeping your home cooler in the summer and warmer in the winter. This can lead to significant energy savings on heating and cooling bills.
- Longevity: A properly installed and maintained cedar shake roof can last 30 to 50 years, and sometimes even longer. This lifespan is considerably longer than the typical 15-20 year lifespan of a standard asphalt shingle roof.
- Durability: Cedar wood contains natural oils and tannins that make it resistant to insect damage, moisture decay, and even ultraviolet radiation. It can withstand harsh weather conditions, including high winds, heavy rain, and impact from hail better than many other materials.
- Environmental Sustainability: Cedar is a renewable resource. Many suppliers practice sustainable forestry. Furthermore, at the end of its long life, cedar shakes are biodegradable, unlike asphalt shingles which contribute significantly to landfill waste.
- Increased Property Value: The high-end, luxurious appearance of a cedar roof can substantially increase the curb appeal and resale value of a property. It signals to potential buyers that the home has been built with quality materials.
However, it is crucial to consider the potential drawbacks to make a fully informed decision.
- Cost: The initial investment for a cedar shake roof is among the highest of all roofing materials. The cost includes not only the premium materials but also the specialized labor required for proper installation.
- Maintenance Requirements: Cedar roofs are not maintenance-free. To preserve their beauty and longevity, they require periodic cleaning to remove moss, algae, and debris. They may also need to be treated with preservatives or fire retardants, depending on local building codes.
- Fire Hazard: Untreated wood is combustible. While cedar shakes are often treated with fire-retardant chemicals to achieve a Class B or Class A fire rating, this is an important factor to verify, especially in areas prone to wildfires.
- Susceptibility to Moisture: If not installed correctly with adequate ventilation and underlayment, cedar shakes can be prone to holding moisture, which can lead to mold, mildew, and rot. Proper installation is non-negotiable.
- Weight: A cedar roof is heavy. It is essential to have a structural engineer assess whether your home’s framing can support the additional weight, especially when replacing a lighter material like asphalt.
The installation process for cedar shake roofing is a specialized craft that should only be undertaken by experienced professionals. It is far more complex than installing asphalt shingles. The process begins with a thorough inspection of the roof deck to ensure it is sound and capable of supporting the weight. A key component is the installation of a high-quality underlayment, often a self-adhering membrane, which provides a critical secondary barrier against water intrusion. Proper ventilation is also paramount; a system of intake and exhaust vents must be installed to allow air to circulate freely beneath the shakes, preventing moisture buildup and promoting drying.
The shakes themselves are typically applied starting from the eaves (the bottom edge of the roof) and working upwards towards the ridge. They are nailed in place using stainless steel or hot-dipped galvanized nails to prevent rust stains. Installers must pay careful attention to the spacing and alignment to ensure a uniform appearance and optimal water shedding. The ridge of the roof is finished with specially cut ridge shakes. Flashing around chimneys, vents, and valleys must be meticulously installed to prevent leaks. This level of detail is why choosing a contractor with specific and proven experience in cedar shake roofing is absolutely critical.
Once your beautiful new roof is installed, a consistent maintenance regimen will ensure it reaches its full lifespan. Here is a recommended maintenance schedule:
- Bi-Annual Inspections: Inspect your roof every spring and fall. Look for signs of damage, such as cracked, curled, or missing shakes.
- Keep it Clean: Remove leaves, pine needles, and other debris from the roof surface and gutters. This prevents moisture retention and blocks that can lead to decay.
- Address Moss and Algae: If you notice green or black growth, have it professionally cleaned. Scrubbing it off yourself can damage the wood. Professionals use specific techniques and cleaning solutions that are safe for cedar.
- Trim Overhanging Branches: This prevents debris accumulation and reduces shade, allowing the roof to dry faster after rain or dew.
- Professional Inspection: Every 3-5 years, have a roofing professional conduct a thorough inspection to identify and address potential issues early.
How does cedar shake roofing compare to its main alternatives? The most common comparison is with asphalt shingles. Asphalt is the most affordable option upfront and is quick to install, but it has a shorter lifespan and offers less insulation. It also lacks the unique aesthetic appeal of cedar. Another alternative is composite or synthetic shake roofing. These products are designed to mimic the look of real wood but are made from recycled plastics, rubber, or other polymers. They are typically more expensive than asphalt but less expensive than real cedar. Their main advantages are being virtually maintenance-free, having a high fire resistance rating, and often coming with very long warranties. However, purists argue that they still lack the authentic, natural charm of real wood.
In conclusion, cedar shake roofing is a premium, long-lasting, and beautiful roofing solution that offers significant benefits in terms of energy efficiency, environmental impact, and property value. Its timeless aesthetic is unmatched by synthetic materials. However, this choice comes with a higher initial cost and a commitment to ongoing maintenance. For the homeowner who values natural materials, classic beauty, and is willing to invest in the long-term health and appearance of their home, cedar shake roofing remains an exceptional and rewarding choice. It is an investment not just in a roof, but in the very character of your dwelling.
