How to Choose the Best Roofing Materials for Washington Rain: Asphalt vs. Metal vs. Cedar

By Tanner Tennyson

If you’ve lived through even one Western Washington winter, you already know your roof does a lot more than just “keep the rain out,” and it’s vital to have the best roofing materials covering your home. Your roof handles months of steady moisture, wind-driven rain, moss growth, and the occasional surprise freeze. Choosing the right material is less about what looks good on day one and more about how it performs year after year in a damp, shaded environment.

Let’s walk through the three most common options we see on homes around Kitsap and the greater Seattle area: asphalt shingles, metal roofing, and cedar shakes. Each one has a place. The key is matching the material to your home, your budget, and how much maintenance you’re willing to deal with.

The Best Roofing Materials for the Pacific Northwest

Asphalt Shingles: The Practical Workhorse

Asphalt is the most common roofing material in Washington for a reason, because it’s one of the best roofing materials you could choose. It’s affordable, widely available, and performs reliably when installed correctly.

What we see in the field:
Most asphalt roofs here don’t fail because of age alone. They fail because of moss buildup, poor ventilation, or flashing issues around penetrations. When those are handled right, asphalt holds up well. Especially if you have a certified Malarkey Shingles installer, like Integrity. Malarkey’s modified asphalt shingles actually live up to their warranty.

Lifespan:
20 to 30 years in our climate, depending on quality and maintenance.

Maintenance Needs:
Moderate. You’ll need to stay on top of moss treatment and keep debris off the roof, especially in shaded areas.

Moss Resistance:
Fair. Algae-resistant shingles help, but they’re not a cure-all in heavily wooded neighborhoods.

Noise:
Quiet. Asphalt absorbs sound well, so rain isn’t something you’ll notice.

Total Cost of Ownership:
Lower upfront cost, but potentially more maintenance over time. Still one of the most cost-effective options overall.

Best Fit For:

• Standard residential homes
• Budget-conscious projects
• Homeowners planning to move within 10 to 15 years

Metal Roofing: Built for Longevity

Metal roofs have gained a lot of traction in Washington, especially in areas with heavy rain and tree coverage. It has become one of the best roofing materials to choose in Washington state.

What we see in the field:
Metal sheds water fast. That matters here. Less standing moisture means less moss, fewer issues with saturation, and better long-term performance.

Lifespan:
40 to 70 years, depending on the system and installation quality.

Maintenance Needs:
Low. Occasional inspections and clearing debris from valleys is usually enough.

Moss Resistance:
Excellent. Moss struggles to take hold on metal surfaces.

Noise Myth (Let’s Clear This Up):
A properly installed metal roof over solid decking is not significantly louder than asphalt. Most homeowners are surprised how little difference there is.

Total Cost of Ownership:
Higher upfront cost, but lower maintenance and longer lifespan often make it more economical over time.

Best Fit For:

• Homes surrounded by trees
• Homeowners planning to stay long-term
• Modern or farmhouse-style homes
• Areas with heavy rainfall exposure

Cedar Shake: Natural Beauty with a Trade-Off

Cedar has a look you just can’t replicate. It fits the Pacific Northwest aesthetic perfectly. But it comes with responsibility.

What we see in the field:
Cedar roofs require consistent care. Without it, they can deteriorate quickly in our damp climate. When maintained properly, though, they can perform well and age beautifully.

Lifespan:
25 to 40 years with proper maintenance.

Maintenance Needs:
High. Regular cleaning, treatments, and inspections are essential to prevent moss and rot.

Moss Resistance:
Low without treatment. Cedar is organic, so it naturally attracts moss in wet environments.

Noise:
Quiet, similar to asphalt.

Total Cost of Ownership:
Higher maintenance costs over time. The aesthetic value is the main driver here.

Best Fit For:

• High-end or historic homes
• Homeowners committed to regular upkeep
• Neighborhoods where cedar is part of the architectural style

Quick Decision Matrix for Western Washington Homes

Here’s a straightforward way to think about it:

A Few Real-World Observations

• Shade matters more than you think. Homes with heavy tree cover will always fight moss. Metal handles that better than anything else.
• Ventilation is critical. Even the best roofing material will fail early if the attic isn’t breathing properly, especially when you consider the effects of moisture on roofing materials.
• Installation quality beats material choice. A poorly installed metal roof will underperform a properly installed asphalt roof every time.

So What’s “Best”?

There isn’t a universal winner here. The best roofing materials are the one that fit your home and your priorities.

• If you want affordability and solid performance, go asphalt.
• If you want long-term durability with minimal upkeep, metal is hard to beat.
• If curb appeal and natural character matter most, cedar is your option, just know what you’re signing up for.
