What Is a Shake Roof
A shake roof refers to a wood roofing system made from split or sawn logs, typically cedar or redwood. Unlike asphalt shingles, shakes have a more rustic, textured appearance that adds natural warmth to a home. They are installed in overlapping layers to shed water and protect the structure beneath. When well-maintained, shake roofs offer good insulation and curb appeal, but they require proper installation and regular upkeep to maximize lifespan and performance.
What Is A Shake Roof
A shake roof uses individual wooden shingles that are thicker and more irregular than standard shingles. The natural grain and varying widths create a distinctive, dimensional surface. Shakes are designed to be weather-resistant, with bark-side edges and deeper cuts that help channels water away from the roof deck. They are heavier than many other roof types and demand precise installation. The result is a durable, long-lasting roof that ages beautifully with proper care.
Materials And Types Of Shake Roofs
Shake roofs are primarily made from softwood species, with cedar and redwood being the most common. Cedar shakes are favored for their resin content, rot resistance, and aroma. Redwood shakes offer natural decay resistance and a lighter color. Some manufacturers produce treated or fire-rated shakes to meet local codes. Shake roofs can come in two main forms: hand-split shakes and sawn shakes. Hand-split shakes tend to be thicker and more textured, while sawn shakes have a flatter profile.
Cedar Shake Shingles
Cedar shakes are popular due to their natural insulation properties and aesthetic appeal. They age to a rich silver-gray patina if left untreated. Cedar resists insects and decay better when kept dry and well-ventilated. Regular maintenance includes cleaning debris, inspecting for cracks, and applying protective treatments as needed.
Redwood And Other Softwoods
Redwood offers stronger rot resistance and a lighter hue. Other softwoods may be used but often require extra treatment to extend life. The choice influences weight, insulation, and fire performance. Local climate and roof pitch should guide material selection to balance longevity with cost.
Benefits And Drawbacks
Shake roofs provide superior curb appeal and natural insulation. The thick, textured surface helps shed rain and snow, and the wood’s natural tannins can deter some pests. However, shakes are more susceptible to weathering, mold, and fire risk than some alternatives. They demand proactive maintenance, including periodic cleaning and treatment. Fire-rated options and proper clearance from nearby trees reduce risk, but ongoing care remains essential for performance.
Installation And Maintenance
Professional installation is crucial for a shake roof’s performance. A correct roof deck, underlayment, and proper nailing patterns prevent leaks and wind uplift. Shakes should be installed with correct gaps to allow for drainage and ventilation. Regular maintenance includes removing organic debris, inspecting for cracked or missing shakes, and resealing or re-staining as recommended by the manufacturer. A professional should assess the roof after storms for damage and reinforce the edges to avoid water intrusion.
Installation Best Practices
- Use high-quality, treated fasteners compatible with wood to reduce warping.
- Install underlayment to provide a secondary moisture barrier.
- Maintain adequate roof ventilation to minimize moisture buildup.
- Place shakes with a uniform overlap to channel water away from the deck.
Maintenance Schedule
- Biannual inspections in spring and fall for loose, cracked, or missing shakes.
- Clean large debris and inspect for mold growth after wet seasons.
- Reapply sealant or protectant as recommended by the manufacturer.
- Trim overhanging branches to reduce moisture and leaf buildup.
Durability, Fire Resistance, And Climate Considerations
Durability hinges on species, grade, and installation quality. Cedar shakes typically last 30 to 50 years with proper care, while redwood may offer similar or longer performance in favorable climates. Fire resistance can be enhanced with Class A fire-rated treatments, yet untreated wood remains vulnerable to embers and rapid ignition. In humid or snowy regions, regular maintenance to prevent moisture buildup is essential to prevent mold and decay. Wind uplift protection is critical in high-wind areas, necessitating robust fasteners and proper edge flashing.
Cost Considerations And Longevity
Shake roofs usually cost more upfront than asphalt shingles due to material and labor. Typical costs range from $7 to $12 per square foot installed for cedar shakes, with variations by region, shake type, and roof complexity. Longevity depends on climate, maintenance, and installation quality, often yielding 30 to 50 years or more with proper care. Ongoing maintenance, including periodic treatments and inspections, adds to lifetime costs but keeps performance high and reduces replacement risk.
Choosing A Shake Roof For Your Home
When deciding on a shake roof, homeowners should consider climate, maintenance willingness, and aesthetic goals. For areas with heavy rainfall or humidity, ensure proper ventilation and chronic moisture control to extend life. If fire risk is a concern, select fire-rated shakes and maintain defensible space around the home. Compare cedar shakes to redwood in terms of availability, color, and decay resistance. Obtain multiple contractor quotes that include underlayment, installation method, and warranty details to ensure a high-quality, durable shake roof.
Frequently Asked Questions
- Do shake roofs require more maintenance than shingles? Yes, shakes generally require more ongoing maintenance to prevent moisture-related issues and decay.
- Can a shake roof be repaired? Individual shakes can be replaced if damaged, but assessments should confirm underlying deck condition.
- Are shake roofs fire resistant? Fire resistance depends on treatment; untreated wood is more flammable, so choose rated products and proper clearance.
- How long do cedar shakes last? With care, cedar shakes typically last 30–50 years.
