Composition vs. Cedar Shake vs. Metal
A Homeowner’s Guide for Redmond, WA from Larry Haight’s Residential Roofing Company
When it comes to protecting your home in Washington State, especially in areas like Redmond, your roof does far more than complete the look of your house. It serves as your first and most important line of defense against persistent rain, moisture, moss growth, and seasonal weather changes.
At Larry Haight’s Residential Roofing Company, we’ve worked with homeowners across the region for decades, and one question consistently comes up: What’s the best roofing material for the Pacific Northwest?
The answer depends on a mix of factors, but climate performance is always at the center of the conversation. In this guide, we’ll compare three of the most common roofing materials, composition shingles, cedar shake, and metal roofing, to help you determine which is best suited for your home.
Understanding Washington’s Climate Challenges
Washington’s climate presents a unique set of challenges for roofing systems. Long stretches of rainfall, combined with high humidity and limited direct sunlight for much of the year, create the ideal conditions for moisture buildup. Even when the rain stops, dampness often lingers on rooftops.
This persistent moisture leads to common issues such as moss, algae, and mildew growth. Over time, these can break down roofing materials, reduce lifespan, and lead to leaks or structural damage if not addressed.
Because of this, roofing materials in Washington need to do more than simply repel water—they must resist moisture absorption, promote proper drainage, and maintain durability over years of exposure. Materials that perform well in dry or hot climates don’t always hold up the same way here.
Composition (Asphalt) Shingles
Composition shingles are the most widely used roofing material in the United States, and they remain a popular choice throughout Washington. Their appeal lies largely in their affordability and versatility, making them accessible to a wide range of homeowners.
They offer solid protection against rain and wind, and modern versions, especially architectural shingles, are designed to be more durable and visually appealing than earlier generations. Because they’re so common, repairs are relatively simple and cost-effective, which adds to their practicality.
That said, composition shingles have some drawbacks in wetter climates. Their surface can retain moisture, which makes them more susceptible to moss and algae growth over time. In a place like Redmond, that means homeowners need to stay proactive with maintenance, including periodic cleaning and treatment.
Lifespan is another consideration. Most composition roofs last around 20 years depending on quality and upkeep. While that’s sufficient for many homeowners, it is shorter than some other materials available today.
Overall, composition shingles are a dependable and budget-friendly option, especially for those willing to invest a bit of time in maintenance.
Cedar Shake Roofing
Cedar shake roofs are closely associated with the Pacific Northwest, and for many homeowners, they represent the classic look of a Washington home. The natural wood texture adds warmth and character, blending seamlessly with the surrounding landscape.
Beyond aesthetics, cedar offers some functional benefits as well. It provides natural insulation and can perform well in a variety of weather conditions when properly maintained. With the right care, cedar shake roofs can last for decades.
However, maintenance is key. Because cedar is an organic material, it is particularly vulnerable to moisture-related issues. Moss, algae, and lichen tend to thrive on cedar surfaces, especially in damp environments. If not regularly treated, these growths can trap moisture and accelerate decay.
Cedar shake roofs also tend to come with a higher upfront cost, and the ongoing maintenance adds to the long-term investment. For homeowners who value appearance and are prepared for the upkeep, cedar remains a strong option. For others, the maintenance demands can be a significant drawback.
Metal Roofing
Metal roofing has become increasingly popular across Washington State, and it’s often considered one of the most effective solutions for wet climates.
One of its biggest advantages is its ability to shed water quickly and efficiently. Unlike materials that absorb moisture, metal surfaces allow rain to run off easily, reducing the likelihood of moss and algae growth. This makes it particularly well-suited for the Pacific Northwest.
Metal roofs are also extremely durable. They can withstand heavy rain, wind, and snow without deteriorating the way some other materials might. In terms of longevity, metal stands out as well—many systems last between 40 and 70 years when properly installed. In addition to their durability, they are also a “green” building option as they are often made from recycled materials.
Another benefit is the low maintenance requirement. Compared to cedar or composition roofs, metal requires very little ongoing care, which is appealing to homeowners who prefer a more hands-off approach.
While metal roofing does come with a higher upfront cost, many homeowners find that the long lifespan and reduced maintenance make it a worthwhile investment over time, and will create budgeting plans for this upgrade. Modern designs also offer a wide range of styles, allowing homeowners to achieve different looks without sacrificing performance.

Our Expert Recommendation
Metal Roofing (Best Overall)
If budget allows, metal is the top choice for PNW homeowners due to:
- Superior moisture resistance
- Minimal maintenance
- Long lifespan
Composition Shingles (Best Value)
A solid, cost-effective option—especially when paired with:
- Proper ventilation
- Moss-resistant treatments
Cedar Shake (Best Aesthetic)
Ideal if you prioritize appearance and sustainability—but be prepared for:
- Regular maintenance
- Higher long-term costs
Choosing a Roof That Matches Your Future Plans
Another factor to consider when choosing a roofing material is how long you plan to stay in your home. If you expect to move within the next 5 to 10 years, a more affordable option like composition shingles may make the most financial sense. They provide reliable protection without the higher upfront cost of premium materials, allowing you to maintain your home’s value without over-investing.
On the other hand, if this is your long-term or “forever” home, investing in a higher-end material like metal roofing can pay off significantly over time. With a lifespan of 40-70 years and minimal maintenance requirements, metal reduces the likelihood of needing another roof replacement down the line. Cedar shake can also be a worthwhile long-term investment for homeowners committed to its upkeep and aesthetic appeal.
What Works Best in Redmond and the Greater Seattle Area?
While these materials can perform well across Washington, areas like Redmond and the greater Seattle region place extra emphasis on moisture resistance due to consistent rainfall and limited sun exposure.
Homes surrounded by trees or shaded areas are especially prone to moss buildup, which makes low-maintenance, moisture-resistant materials like metal particularly appealing. That said, many homeowners still choose composition or cedar based on budget or aesthetic preferences, as long as they are prepared for the associated upkeep.
Why Professional Installation Matters
Even the best roofing material won’t perform as expected if it isn’t installed correctly. In fact, many roofing issues stem from poor installation rather than the material itself.
Proper ventilation, drainage, and flashing are all critical in a wet climate. Without them, moisture can become trapped, leading to premature wear and potential damage.
At Larry Haight’s Residential Roofing Company, we focus on installing roofing systems designed specifically for Washington’s conditions. Our experience allows us to address the challenges of moisture, moss, and long-term durability, helping homeowners get the most out of their investment.
Pick the Best Roofing Material for Your Needs
Choosing the right roofing material in Washington State requires careful consideration of both performance and priorities. Composition shingles offer affordability and versatility, cedar shake provides unmatched natural beauty, and metal roofing delivers exceptional durability and low maintenance.
Each option has its place, but in a climate defined by moisture, materials that resist water and require less upkeep often provide the greatest long-term value.
If you’re planning a roof replacement or new installation, taking the time to evaluate your options—and working with an experienced local contractor—can make all the difference. A well-chosen roof doesn’t just protect your home today; it ensures lasting performance for years to come.
Frequently Asked Questions About Washington State’s Best Roofing Materials
Q: How do I prevent moss and algae from growing on my roof?
A: Moss and algae thrive in damp, shaded environments, making them a common concern in Washington. Regular roof maintenance is key, including cleaning debris, trimming overhanging branches to allow more sunlight, and applying moss-resistant treatments. Some roofing materials, like metal, naturally resist moss growth better than others, while composition and cedar roofs may require more frequent upkeep.
Q: Are composition shingles good enough for Washington’s rainy climate?
A: Yes, composition shingles can perform well in Washington as long as they are properly installed and maintained. They are designed to shed water effectively, but because they can retain some moisture, regular maintenance, such as moss treatment and cleaning, is important to maximize their lifespan
Q: Do metal roofs make more noise when it rains?
A: This is a common concern, but in most residential applications, metal roofs are installed with solid sheathing and insulation beneath them. This significantly reduces noise, making them comparable to other roofing materials in terms of sound during rainfall.
