A cedar shake roof combines natural beauty with reliable performance, making it a popular choice for homeowners who want durability and rustic appeal. Each hand-split shake offers unique textures and patterns, creating a roof that stands out while blending seamlessly into natural surroundings.
Installing a cedar shake roof requires attention to detail, proper preparation, and an understanding of traditional roofing techniques. The process involves more than simply attaching shingles, as ventilation, underlayment, and fastening methods play crucial roles in longevity.
Let’s look at how to install cedar shake roof. With the right tools, materials, and methodical guidance, the result is a roof that protects the home for decades and enhances property value.
Preparing for Installation
Proper preparation sets the stage for a successful cedar shake roof project and ensures that the installation runs smoothly. Planning ahead helps avoid delays, wasted materials, and structural issues that could arise later.
Cedar shakes require specific conditions to perform optimally, including a roof structure that can support their weight and withstand moisture. Preparation also involves gathering the right tools, evaluating the home’s framework, and confirming building codes.
- Evaluating the Roof Structure
The roof deck must be inspected thoroughly to confirm it can handle the load of cedar shakes, which are heavier than asphalt shingles. Any signs of rot, sagging, or water damage need repair before installation begins.
A solid sheathing such as plywood or OSB provides a stable foundation for shakes. Secure nailing surfaces are essential because loose boards can compromise the roof’s integrity over time.
Roof pitch is another critical factor in determining shake suitability. Cedar shakes perform best on slopes of 4:12 or steeper, allowing water to run off effectively.
- Gathering Tools and Materials
Essential tools for cedar shake installation include roofing hammers, chalk lines, nail guns, circular saws, and ladders. Materials go beyond the shakes themselves and often include underlayment, felt paper, nails, and ventilation components.
| Category | Items Needed | Importance |
| Tools | Roofing hammer, nail gun, circular saw, chalk line, ladder | Ensure precision and efficiency during installation |
| Materials | Cedar shakes (bundled), underlayment, felt paper, flashing, nails | Quality affects durability and performance |
| Safety Gear | Harness, gloves, goggles, non-slip boots | Protects installers from accidents and injuries |
Quality fasteners such as stainless steel or hot-dipped galvanized nails are recommended for resistance against corrosion. Shakes are usually purchased in bundles, and sorting them by thickness beforehand makes the installation process more organized.
Proper handling and storage also prevent splitting or warping before use.
Meeting Building Codes and Regulations
Local building codes may specify requirements for cedar shake installation, including underlayment type, ventilation, and fire resistance. Ignoring these codes can lead to failed inspections and forced roof modifications.
Some regions also mandate fire-retardant treatments for cedar shakes, particularly in wildfire-prone areas. Complying with these standards ensures both safety and legal adherence.
Permits are typically required before work begins, and securing them avoids penalties or delays. Homeowners benefit from consulting their municipality’s building office early in the planning process.
Installing the Underlayment
The underlayment forms a crucial moisture barrier beneath cedar shakes, protecting the roof deck from leaks. It also helps regulate ventilation and prevents trapped condensation.
High-quality underlayment not only extends the roof’s lifespan but also ensures the cedar shakes can perform to their full potential. A properly installed underlayer provides an additional safeguard against weather extremes.
Selecting the Right Underlayment
Traditional felt paper remains a common choice for cedar shake roofing because it allows the shakes to breathe. Synthetic underlayments are also available, offering increased durability and resistance to tearing.
In cold climates, an ice and water shield may be necessary for added protection along eaves and valleys. Selecting the correct product depends on regional climate and building code requirements.
Thicker underlayments can sometimes interfere with ventilation, so balance is key. Professional roofers often recommend combinations that match both performance and local regulations.
Laying the First Course
Installation begins at the roof’s lower edge, with underlayment rolled horizontally and secured with nails or staples. Overlapping sections by several inches prevents water from seeping between layers.
A straight chalk line ensures the underlayment is aligned correctly, avoiding uneven coverage. Proper alignment also simplifies shake installation by providing a consistent base reference.
Careful trimming around roof features such as chimneys and vents prevents gaps that could lead to leaks. Every edge must be sealed tightly to maintain the underlayment’s effectiveness.
Overlapping and Ventilation Gaps
Each successive row of underlayment must overlap the previous row to create a watertight seal. The overlap distance depends on roof pitch and product specifications.
Some installation methods include using skip sheathing, which leaves small gaps between boards for airflow. This enhances ventilation and allows shakes to dry after exposure to moisture.
Ventilation is crucial for cedar shake longevity because trapped moisture accelerates decay. Balancing overlap with breathability ensures optimal performance.
Installing Cedar Shakes
Once the underlayment is secured, cedar shakes can be installed with precision and care. This phase requires attention to spacing, alignment, and fastening techniques.
Cedar shakes expand and contract naturally with moisture, so proper spacing helps accommodate seasonal changes. A uniform installation ensures both visual appeal and structural strength.
Starting the First Row
The first course of shakes is installed at the eaves, overlapping the drip edge for water runoff. This foundational row must be straight because it influences the alignment of every subsequent row.
Each shake is nailed about one inch from the edge and approximately two inches above the exposure line. Fastening too tightly can split the wood, while loose nails weaken the hold.
The spacing between shakes is typically 3/8 to 5/8 inch to allow for expansion. Consistent gaps prevent warping and keep the roof breathable.
Layering for Proper Coverage
Cedar shake roofs require a staggered pattern, with joints offset in each row to prevent water channels. Installing shakes in a random but organized pattern creates a natural, appealing look.
Each course overlaps the one below it, with exposure commonly ranging between 7.5 and 10 inches. The chosen exposure impacts both aesthetics and water-shedding ability.
Double layering is standard in the first few rows to strengthen the roof’s edge. This reinforcement provides added protection against wind-driven rain.
Securing Valleys and Ridges
Valleys, where two roof slopes meet, are especially vulnerable to water intrusion. Metal flashing is installed first, followed by carefully cut shakes that fit snugly alongside.
At ridges, special ridge cap shakes are used to protect the peak. These caps are often thicker and shaped to shed water effectively.
Proper sealing and fastening in these areas ensure long-term durability. Overlooking valleys and ridges is a common cause of premature roof failure.
Finishing Touches and Maintenance
Once installation is complete, finishing details enhance both functionality and appearance. These final steps ensure the roof performs well in all weather conditions.
Ongoing maintenance also plays a vital role in preserving the natural beauty and structural reliability of cedar shakes. Regular care extends the roof’s lifespan significantly.
Applying Protective Treatments
Cedar shakes can be treated with preservatives to resist fungi, mold, and insects. Treatments also help maintain the wood’s natural color and slow weathering.
In areas prone to fire risk, fire-retardant treatments may be required. These chemical applications increase safety without compromising the natural character of the wood.
Treatments should be reapplied periodically to remain effective. A professional contractor can recommend a schedule based on climate and exposure.
Conducting Routine Inspections
Regular inspections help identify loose shakes, nail pops, or early signs of rot. Catching these problems early prevents more extensive damage.
Seasonal checks are particularly useful after storms, heavy snow, or high winds. Addressing small repairs promptly avoids costly replacements later.
Cleaning the roof of debris such as leaves and branches reduces moisture retention. Keeping the surface clear improves both airflow and durability.
Planning for Long-Term Care
Cedar shakes naturally weather to a silver-gray hue over time, which many homeowners find appealing. Maintenance plans should account for both functional care and desired aesthetics.
Power washing is discouraged, as it strips away protective layers of the wood. Instead, gentle cleaning methods preserve the integrity of the shakes.
Professional maintenance services may be beneficial for homeowners with steep or complex roofs. Regular professional care often adds decades to the roof’s lifespan.
