Cedar roofing is a timeless and durable choice for homeowners looking to enhance curb appeal and longevity. But how long do cedar roofs last? With proper care, a cedar roof lifespan can reach 30 to 50 years—or even longer. Understanding the factors that affect cedar roof durability and implementing regular maintenance can help extend its life and maximize your investment.
In this guide, we’ll explore what impacts how long cedar roofs last, how to maintain them, and why they remain a popular choice for homeowners seeking long-term value.
The Lifespan of a Cedar Roof: What to Expect
A properly maintained cedar roof lifespan typically falls between 30 and 50 years. However, some homeowners have reported their cedar roofs lasting over 60 years with professional care and ideal conditions.
Cedar Shake vs. Cedar Shingle: Does It Make a Difference?
The type of cedar roofing you choose can influence its longevity:
| Type | Lifespan | Characteristics |
| Cedar Shingles | 30-40 years | Machine-cut, uniform, thinner |
| Cedar Shakes | 40-50 years | Hand-split, thicker, more textured |
Cedar shakes tend to last longer due to their thickness and rugged construction, making them more resistant to harsh weather conditions.
Factors That Affect Cedar Roof Longevity
While cedar is naturally durable, several factors influence how long cedar roofs last.
1. Climate and Weather Conditions
Cedar roofs perform well in various climates, but they are especially suited for regions with moderate humidity and well-ventilated roofing systems.
- Wet Climates: Cedar is naturally moisture-resistant, but excessive humidity can cause mold and mildew.
- Dry Climates: Prolonged exposure to intense sunlight can dry out cedar, making it more prone to cracking.
- Storm-Prone Areas: Strong winds and heavy rainfall can shorten the cedar roof lifespan without proper maintenance.
2. Installation Quality
A poorly installed roof will fail much sooner than one installed by experienced professionals. Proper ventilation, underlayment, and fasteners all play a role in ensuring how long a cedar roof lasts.
To ensure quality installation, choose a contractor with expertise in cedar roofing, like AWS Restorations, to maximize your investment.
3. Cedar Wood Quality
Not all cedar roofing materials are the same. The highest-quality cedar comes from old-growth Western Red Cedar, known for its:
✔ Natural oils that resist decay
✔ Tight grain structure for durability
✔ Resistance to insect infestations
Lower-quality cedar will deteriorate faster, leading to higher maintenance costs.
4. Proper Maintenance
Routine maintenance plays a major role in extending how long a cedar roof lasts. Regular inspections, cleaning, and protective treatments can prevent premature aging.
How to Extend the Life of Your Cedar Roof
Regular maintenance is essential for preserving the cedar roof lifespan. Here’s what you can do to keep your cedar roof in top shape.
1. Schedule Regular Roof Inspections
An annual inspection helps identify potential problems before they turn into costly repairs. A professional roofer will check for:
- Loose or damaged shingles/shakes
- Signs of rot or mold
- Proper ventilation and drainage
The U.S. Department of Energy recommends regular roof inspections to improve energy efficiency and extend roof lifespan.
2. Clean Your Roof to Prevent Moss and Algae Growth
Moss and algae can trap moisture and accelerate wood decay. To prevent this:
✔ Gently remove moss with a soft-bristle brush
✔ Use a mild cedar-safe cleaner (avoid harsh chemicals)
✔ Trim overhanging tree branches to reduce shade and excess moisture
3. Apply Protective Treatments
Applying a cedar wood preservative every few years can extend how long cedar roofs last. These treatments:
✔ Prevent moisture damage
✔ Protect against UV exposure
✔ Reduce the risk of insect infestations
Look for a preservative that is environmentally friendly and specifically designed for cedar roofing.
4. Maintain Gutters and Drainage Systems
Clogged gutters can lead to water pooling on your roof, accelerating deterioration. Ensure gutters are:
- Cleaned twice a year
- Free of blockages
- Positioned to direct water away from the home
According to the Environmental Protection Agency, proper drainage prevents water damage and protects home structures.
5. Repair or Replace Damaged Shingles Promptly
If you notice cracked or missing cedar shingles, replace them immediately. Even minor damage can lead to leaks and structural issues over time.
Cedar Roofing vs. Other Roofing Materials
Before choosing cedar, it’s important to compare its lifespan with other common roofing materials.
| Roofing Material | Lifespan | Maintenance Level | Cost |
| Cedar Shingles | 30-40 years | Moderate | Medium |
| Cedar Shakes | 40-50 years | Moderate | Medium |
| Asphalt Shingles | 20-30 years | Low | Low |
| Metal Roofing | 40-70 years | Low | Medium |
| Slate Roofing | 75-100 years | Low | High |
Cedar roofs provide a unique balance of natural beauty, durability, and value, making them a strong choice for homeowners looking for long-term performance.
Is a Cedar Roof Worth the Investment?
For homeowners asking, how long do cedar roofs last, the answer is clear: they provide decades of durability when properly maintained. But is it worth the investment?
✔ Higher home value – Adds curb appeal and resale value
✔ Natural insulation – Helps reduce heating and cooling costs
✔ Long lifespan – Outlasts asphalt shingles
✔ Eco-friendly choice – Made from renewable resources and biodegradable materials
If you’re looking for a roofing material that blends aesthetic appeal, sustainability, and longevity, cedar is a fantastic option.
