What Is A Wood Shake Roof

A wood shake roof is a roof covering made from hand-split or machine-split pieces of wood designed to provide a layered, textured appearance and natural insulation. Shakes Are Thicker And More Irregular Than Shingles, giving a rugged look favored in craftsman, cottage, and historic-style homes.

Wood Shake Vs Wood Shingle: Key Differences

Wood shakes and wood shingles are often confused but have distinct manufacturing methods and appearances. Wood Shakes Are Split To Create A Rough Surface; Shingles Are Sawn For Uniformity, so shakes tend to be thicker, more durable in some cases, and more rustic in appearance.

Common Materials Used For Wood Shakes

Cedar is the most common wood for shakes due to its natural resistance to decay and insects. Other woods include redwood and eastern white cedar. Cedar Offers A Balance Of Durability, Workability, And Aesthetic Appeal that suits many U.S. climates.

How Wood Shake Roofs Are Made And Installed

Hand-split shakes are created by splitting logs along the grain, producing thicker, tapered pieces. Machine-made shakes are sawn then sometimes textured. Proper Installation Requires Attention To Underlayment, Ventilation, And Fastening Techniques to ensure longevity and reduce leak risk.

Installation Components

Typical installation includes a breathable underlayment, starter courses, staggered courses of shakes, flashing around penetrations, ridge caps, and a ventilation strategy. Experienced Roofers Follow Manufacturer Specs And Local Code because spacing, exposure, and fastening patterns directly affect performance.

Advantages Of A Wood Shake Roof

Wood shake roofs provide aesthetic warmth and unique texture that is difficult to replicate with other materials. They offer natural insulation properties and can increase property value for homes where the look fits the architecture. Wood Shakes Are Environmentally Friendly When Sourced From Sustainable Forestry and are biodegradable at end of life.

Drawbacks And Risks

Wood shake roofs carry notable drawbacks: vulnerability to fire without treatment, higher maintenance needs, risk of rot and insect damage in damp climates, and higher initial cost compared to asphalt. Fire Risk Is A Primary Concern—Untreated Wood Is Class C Or Lower By Default.

Fire Safety And Treatment Options

Treating shakes with fire-retardant chemicals can improve ratings and reduce insurance impacts. Options include factory-treated shakes or on-site treatments and adding a fire-resistant underlayment or gypsum board sheathing. Some Local Codes Or Insurance Policies Require Class A Or B Ratings For Certain Areas, so homeowners should verify requirements before installing wood shakes.

Cost Factors And Typical Price Ranges

Installed cost varies with material, roof complexity, and geographic labor rates. Expect $6.50 To $12.00 Per Square Foot Installed for quality cedar shakes, with high-end projects possibly exceeding that due to steep slopes or custom detailing.

What Influences Cost

• Shake Grade And Thickness: Premium hand-split shakes cost more.
• Roof Complexity: Valleys, dormers, and steep pitch increase labor.
• Removal Of Old Roofing: Tear-off and deck repairs add to costs.
• Local Labor Rates And Permit Costs

Lifespan And Factors That Affect Longevity

Wood shake roofs typically last 20 To 40 Years depending on climate, maintenance, ventilation, and the quality of materials and installation. Regular inspections and timely repairs can extend service life significantly.

Key Longevity Factors

1. Climate: Hot, dry climates preserve shakes better than wet, humid areas.
2. Ventilation: Proper attic ventilation prevents heat and moisture buildup.
3. Maintenance: Cleaning debris, replacing damaged shakes, and treating for mold extend lifespan.

Maintenance Best Practices

Routine maintenance keeps wood shake roofs performing and prevents costly damage. Recommended actions include regular inspections, cleaning gutters, removing moss and debris, replacing damaged shakes promptly, and applying preservative or fire-retardant treatments as needed. Proactive Maintenance Is Critical To Maximizing Lifespan.

Inspection Checklist

• Look For Broken, Split, Or Buckled Shakes
• Check Flashing Around Chimneys, Vents, And Valleys
• Inspect For Algae, Moss, Or Mold Growth
• Confirm Proper Ventilation And Attic Conditions

Repair Versus Replacement

Small localized problems like cracked shakes or lifted flashing can be repaired. Widespread rot, extensive moss damage, or age near the end of life may justify full replacement. Repair Costs Are Lower Short-Term, But Delaying Replacement Can Increase Long-Term Expense.

Insurance And Building Code Considerations

Insurance companies often view wood shake roofs as a higher fire risk, which can raise premiums or lead to restrictions. Some jurisdictions limit the use of untreated wood shakes in fire-prone areas. Homeowners Should Consult Insurance Providers And Local Building Departments Before Installation.

Alternatives To Wood Shakes

Synthetic shake products, composite materials, and slate-look asphalt options offer shake aesthetics with lower maintenance, longer warranties, and improved fire ratings. Modern Synthetic Shakes Can Mimic The Look Of Wood While Offering Better Fire And Rot Resistance.

How To Choose The Right Wood Shake For A Home

Selection should weigh architectural style, climate, budget, and long-term maintenance willingness. Homeowners should ask for sample shakes, verify treatment options, compare installer experience, and review local code or insurance constraints. Choosing A Certified Installer And Quality Materials Reduces Future Problems.

Finding A Qualified Installer

Look for roofing contractors with specific experience installing wood shakes, licensing and insurance, manufacturer certifications, and verifiable references. A thorough written estimate should include materials, underlayment, ventilation strategy, flashing details, and warranty terms. installers Should Provide Clear Documentation On Materials And Workmanship Warranties.

Frequently Asked Questions

Do Wood Shake Roofs Leak More Than Other Types?

Properly installed wood shake roofs are not inherently leak-prone; most issues stem from poor flashing, improper spacing, or deck problems. Skilled Installation And Regular Inspection Minimize Leak Risk.

Can Wood Shakes Be Treated For Fire Resistance?

Yes. Chemical treatments and additional protective layers can improve fire ratings, although treatment effectiveness may decline over time and require reapplication. Confirm Treatment Lifespan And Reapplication Needs With The Manufacturer.

Is A Wood Shake Roof Environmentally Friendly?

When sourced from certified sustainable forestry, wood shakes are renewable and biodegradable, making them a greener choice than many petroleum-based alternatives. Choice Of Supplier And End-Of-Life Disposal Affect Environmental Impact.

Practical Next Steps For Homeowners Considering Wood Shakes

Homeowners should obtain multiple contractor bids, request material samples, confirm local code and insurance implications, and include a ventilation plan in proposals. Comparing Warranties And Long-Term Maintenance Costs Is Crucial Before Committing.

Overall, a wood shake roof provides distinctive beauty and natural insulation but requires informed selection, proper installation, and ongoing maintenance to realize its benefits and minimize risks.
