West Coast Weather Realities

When your neighborhood is basically a rainforest with city lights, you know moisture is more than just the occasional drizzle. Our West Coast region faces consistent rain—often at unpredictable intervals. One moment you’re basking in sunshine along the seawall, and the next, it’s downpour central. That means if your roof can’t handle humidity, dampness, and an overall watery onslaught, you’ll soon notice issues like warping or splitting. Sometimes you’ll even find moss that thinks it’s on vacation in some enchanted forest growing right on your roof.

Thankfully, cedar shakes can handle these conditions if you choose the proper grade and ensure precise installation. Being prepared for our climate’s intense and relentless dampness is key. So if you’re going to invest in cedar, you want to be sure your roof is up for the challenge of all that west coast precipitation.

Why Cedar Shakes Are a Popular Choice

Cedar remains a favorite for many homeowners in the Lower Mainland. Part of its popularity is the natural aesthetic: it looks warm, rustic, and a bit like the North Shore mountains decided to cozy up on your rooftop. Another reason is cedar’s natural resilience, as people have used cedar shakes for centuries, not just for beauty but for their inherent ability to stand against the elements.

There’s also the West Coast mindset: we love blending into nature. A cedar roof among coniferous forests makes sense. Cedar is moderately lightweight compared to materials like tile or slate. Plus, it’s a decent insulator, which helps keep the interior cooler in our sporadic summer heat and warmer when the skies are pouring.

Varieties of Cedar Shakes

Not all cedar is the same. In our region, two common cedar shake varieties are Alaskan Yellow Cedar and Western Red Cedar. Each brings different characteristics, and understanding these can help you pick what’s best for your particular home.

Alaskan Yellow Cedar Shakes

Alaskan Yellow Cedar (Cupressus nootkatensis) is prized for its density and robust structure. Its pale, soft yellow hue gives a unique aesthetic that some homeowners love. From a roofer’s perspective, this density translates to excellent durability. Alaskan Yellow Cedar also resists rot and decay, thanks to its tight grain.

This type of cedar shake isn’t magic, but it’s close. It stands up well to the rain and dampness that Vancouver and surrounding areas dish out. However, it can be more expensive than Western Red Cedar, primarily due to relative scarcity. If your budget allows, Alaskan Yellow Cedar can be an amazing ally against wind-driven rain while providing that distinct look.

Western Red Cedar Shakes

Western Red Cedar is more common and has a classic cedar aroma many of us in BC adore. It starts off a ruddy-brown shade and can weather to a silvery patina if not stained. The natural compounds—thujaplicins—help fight fungus and insects, making it a great option for our wet environment.

As with any natural product, quality matters. Not all Western Red Cedar is created equally, so aim for higher grades if you want to minimize early rot or curling. It’s a popular choice, often more accessible than Alaskan Yellow Cedar, and carries that quintessential “West Coast” vibe.

How Moisture Affects Cedar Shakes

Moisture is a tricky beast. Cedar contains natural protective oils, but the near-constant rain and dampness can eventually permeate the wood if left untreated or poorly maintained. This can lead to swelling, warping, or splitting—especially when the sun decides to pop out and dry everything up right after a downpour.

Another impact is the potential for algae, moss, or fungi growth. In areas shaded by large trees, the roof can remain damp for extended periods. That’s why a regular cleaning routine matters. Take a look now and then—if moss is having a field day on your cedar shakes, it’s time for a gentle cleanup.

Treatments and Finishes: Keeping Mold at Bay

Cedar has natural antifungal properties, but with our drizzly climate, an extra line of defense never hurts. Modern treatments and finishes can help maintain the wood’s integrity. These range from clear penetrating finishes (showing off the cedar’s natural grain) to semitransparent stains offering both color and protection.

Products containing mildewcides can stave off mold and mildew. Additionally, if you love that rich cedar color and don’t want it fading to gray, these finishes help slow that process. A well-sealed cedar shake is less likely to absorb water, giving you a better shot at longevity. Just remember: not all finishes are equal, so choose a formulation specifically designed for cedar in rainy climates.

For those who want an especially durable product, pressure-treated cedar shakes might be appealing. They undergo a process where preservatives are forced into the wood fibers under high pressure, creating a formidable shield against moisture, insects, and fungus. If you’re serious about longevity in Vancouver’s wet environment, it’s certainly worth exploring.

Installation Techniques for Damp Climates

Even high-grade cedar shakes will fail if installed poorly. For a rainy climate, attention to detail is everything. Here are some key points:

• Proper Spacing: Cedar expands and contracts. Too tight, and shakes can buckle when they swell; too loose, and you risk leaks.
• Underlayment: Use a high-quality underlayment designed for cedar. It creates a secondary moisture barrier.
• Nails & Fasteners: Galvanized or stainless steel nails only—regular steel will rust in our climate.
• Ventilation: Adequate airflow keeps the shakes from staying soaked. Moisture that lingers is trouble.
• Flashing: Around vents, chimneys, and skylights, ensure seamless integration with your cedar shakes to block water from sneaking in.

I like to say: “Spend the time now, save headaches later.” With the right technique, your cedar roof can stand tall against our relentless drizzle.

Maintenance 101: Keeping Cedar Healthy

Maintenance might sound daunting, but trust me—it doesn’t have to be a chore. Cedar shakes thrive with routine attention, especially in our climate. Here are a few simple tips:

• Routine Inspections: Walk around your property (or carefully up a ladder if you’re skilled) every spring and fall to spot cracked or missing shakes.
• Cleaning: A gentle scrub or a low-pressure wash can remove moss or debris. Avoid high-pressure washing, which can damage the wood surface.
• Debris Removal: Clear out leaves, pine needles, and other matter to keep the shakes dry and moss-free.
• Re-Finishing: If your shakes are stained or sealed, expect to reapply the finish every few years, as per manufacturer guidelines.

Regular maintenance is your best insurance policy. A bit of elbow grease now will save you much bigger issues down the line.

Life Expectancy: Realities of Cedar Durability

A well-installed and properly cared-for cedar shake roof can last anywhere from 20 to 40 years, sometimes longer. Western Red Cedar shakes of prime grade can often go beyond 30 years, while the denser Alaskan Yellow Cedar might extend that even further.

Keep in mind that we live in a region with heavy rainfall, occasionally punishing storms, and quick transitions between wet and dry. Neglecting your roof can drastically reduce its lifespan. But when you pair quality materials with the right maintenance mindset, cedar can truly stand the test of time.

Ventilation Matters—A Lot

Ventilation is the unsung hero of a long-lasting cedar roof. When moist air gets trapped, it can lead to condensation on the underside of the roof deck, setting the stage for mold, rot, and an overall shorter roof life. Proper attic vents, soffit vents, and ridge vents work together to help moisture escape.

If you sense a musty smell in your attic or see signs of mildew, lack of ventilation could be the culprit. Addressing ventilation is often a cost-effective solution that reaps huge benefits in the longevity of your cedar shakes.

Budgeting and Cost Factors

Let’s be real—no one loves paying for a new roof. But you’re investing in the safety and longevity of your home. Cedar shakes generally cost more than some other materials, but many homeowners find that classic look and proven performance worth it. Here are some elements that affect your total cost:

• Material Grade: High-grade cedar shakes have fewer knots and imperfections but come at a higher price.
• Treatments: Pressure-treated or pre-finished shakes are more expensive upfront but can reduce future maintenance.
• Complexity of Installation: If your roof is steep or has multiple dormers, chimneys, or skylights, labor costs will naturally rise.
• Maintenance Approach: Budget for periodic inspections and re-finishing to protect your investment over the long haul.

My advice? Don’t skimp on materials or installation. Cutting corners now could cost you far more if moisture seeps in and wreaks havoc.

Frequently Asked Questions About Cedar Shakes

How Do I Know My Shakes Are High Quality?

Look for cedar shakes bearing a legitimate grading stamp from reputable mills. High-grade shakes often say things like “Clear Heart” or “100% straight grain.” You want shakes with minimal knots and consistent thickness. If you can bend one slightly without it cracking, that’s a good sign of quality and flexibility—important in our rainy, shifting climate.

Do Cedar Shakes Need Recoating Over Time?

Indeed, they do. If you want your shakes to retain their protective properties and color, plan on periodic re-staining or re-sealing, usually every five years or so (though this can vary). This step helps combat the constant barrage of rain and UV rays, ensuring the wood doesn’t dry out too much and fall victim to cracks or rot.

Is Cedar Roofing Noisy in the Rain?

Not at all. In fact, cedar shakes can dampen sound better than metal roofing, for instance. Many homeowners say the gentle pitter-patter of rain on cedar is downright soothing—a lullaby courtesy of the West Coast climate. Embrace it.
