Asphalt Shingles vs Cedar Shakes in the PNW: Cost, Maintenance, and Longevity

For homeowners in the Pacific Northwest, choosing a roofing material is a critical decision that balances aesthetics, performance, and budget. Two of the most popular options, asphalt shingles and cedar shakes, represent a classic clash between modern convenience and timeless, natural beauty. Both can be excellent choices, but they offer very different experiences in terms of cost, maintenance, and longevity, especially in the unique climate of the PNW.

This guide compares asphalt shingles and cedar shakes to help you decide which is the right fit for your home.

Aesthetic Appeal

• Cedar Shakes: For many, the appeal of cedar is purely aesthetic. Cedar shakes offer a beautiful, natural, and rustic look that is quintessential to the Pacific Northwest. The cedar roof appears rich and textured, and it weathers to a distinguished silvery-grey over time. It is a premium look that adds significant curb appeal. Each shake is unique, creating a character and depth that cannot be perfectly replicated by manufactured materials. This is a major selling point for homeowners in areas such as the Portland metro and Vancouver metro, where a connection to the natural landscape is highly valued.
• Asphalt Shingles: While more common, modern architectural asphalt shingles have advanced significantly. They are available in a vast array of colors and styles, including options that mimic the look of slate, wood, or tile. They offer a clean, consistent look that can complement any home style.

Cost Comparison

• Cedar Shakes: Cedar is a premium material, and its cost reflects that. The material itself is more expensive, and the installation is more labor-intensive and requires specialized expertise, further increasing the upfront cost. A cedar shake roof is a significant investment.
• Asphalt Shingles: Asphalt shingles are the more budget-friendly option. Both the material and the installation are less expensive, making them the most common choice for residential roofing projects. This lower upfront cost allows homeowners to allocate their budget to other areas of a home renovation. Furthermore, the widespread availability and competition among installers can make it easier to find a qualified and affordable contractor. For many, this makes a roof replacement a much more accessible project.

Maintenance in the PNW Climate

This is where the two materials diverge most significantly, especially in our damp climate.

• Cedar Shakes: Cedar requires regular maintenance to thrive in the PNW. It is an organic material and is susceptible to moss, algae, and rot if not properly cared for. This includes regular roof cleaning, treatments to prevent moss and fungus, and ensuring good airflow to allow the shakes to dry. This maintenance is essential to reach the material’s full lifespan.
• Asphalt Shingles: Asphalt shingles are significantly lower maintenance. While they should be kept clear of debris, they are far less susceptible to rot. Many modern shingles are manufactured with copper granules that inhibit the growth of algae, making them an excellent low-maintenance choice for the PNW. This is a key reason they are considered one of the best roof types for the Pacific Northwest.

Longevity and Durability

• Cedar Shakes: A well-maintained cedar shake roof can last 30 years or more. However, its lifespan is directly tied to the quality of the installation and the diligence of the maintenance. Without proper care, a cedar roof can fail prematurely in the damp PNW climate.
• Asphalt Shingles: High-quality architectural asphalt shingles typically have a lifespan of 20 to 30 years. They are durable and withstand wind and rain. Their lifespan is less dependent on homeowner maintenance, making them a more “set it and forget it” option.

Environmental Impact

• Cedar Shakes: Cedar is a natural, renewable resource. However, the harvesting of old-growth cedar has environmental implications. It is important to source cedar from sustainably managed forests. At the end of its life, cedar is biodegradable.
• Asphalt Shingles: Asphalt is a petroleum-based product. However, the industry has made significant strides in recycling old asphalt shingles into pavement. Many modern shingles also contain recycled materials. The environmental impact is a complex issue with trade-offs on both sides.

So Which is Right for You?

The choice between asphalt shingles and cedar shakes comes down to your priorities.



• Choose Cedar Shakes if: You are in love with the natural aesthetic, have a larger budget, and are committed to the regular maintenance required to protect your investment.
• Choose Asphalt Shingles if: You are looking for a cost-effective, low-maintenance, and reliable roofing solution that still offers a wide range of aesthetic options.

For most homeowners in the Pacific Northwest, the convenience, reliability, and cost-effectiveness of architectural asphalt shingles make them the more practical choice. However, for those who prioritize natural beauty above all else, the timeless appeal of a cedar shake roof is hard to beat.
