For Seattle’s rainy weather, fiber cement and metal siding offer top performance with minimal upkeep. Vinyl is a cost-effective choice, while composite balances durability and aesthetics. Cedar/redwood suits those valuing natural beauty but requires consistent care.
1. Fiber Cement Siding
Fiber cement siding is a blend of cement, sand, and cellulose fibers that offers the look of wood while standing up to Seattle’s notoriously damp weather. Brands like James Hardie, with its HardiePlank line specially designed for wet climates, and CertainTeed provide excellent options for moisture-heavy environments. Let’s break down why fiber cement is a standout choice for durability, weather resistance, low maintenance, and overall value.
Durability and Longevity
When installed correctly, fiber cement siding can last anywhere from 50 to 100 years. Its cement-based construction makes it naturally resistant to termites and other pests, while also holding up against decades of moisture exposure without losing its structural integrity.
Weather Resistance (Moisture, Wind, and UV)
Seattle’s heavy rain is no match for fiber cement siding. Its low moisture absorption prevents common issues like swelling, warping, and rot. The material’s weight and rigidity also make it highly resistant to strong winds. Plus, it holds up well against UV rays during sunnier spells, and its non-combustible properties add an extra layer of fire safety.
Maintenance Requirements
One of fiber cement’s big perks is how little maintenance it needs. Routine care includes occasional cleaning, checking caulking every 5–10 years, and repainting every 10–15 years – unless you choose pre-finished options, which can stretch that timeline even further.
Cost Considerations
The cost to install fiber cement siding in Seattle ranges between $10 and $14 per square foot. While the upfront expense is on the higher side, its impressive lifespan and low maintenance requirements make it a cost-effective option in the long run.
2. Vinyl Siding
Vinyl siding is a popular and cost-effective choice for Seattle homeowners looking for durable exterior protection. In fact, it’s the most widely installed siding material across the United States, covering over 25% of new single-family homes nationwide.
Durability and Longevity
Vinyl siding typically lasts between 20 and 30 years, with premium-grade options stretching up to 40 years. It naturally resists rot, flaking, and insect damage, which is a big plus in Seattle’s damp climate. That said, during rare cold spells, vinyl can become brittle and more prone to cracking if struck. Many homes across the Seattle area showcase vinyl siding that has stood the test of time, maintaining both its appearance and functionality despite the region’s heavy rain and winds. Opting for thicker, higher-quality vinyl panels can improve durability and help withstand stronger winds.
Weather Resistance (Moisture, Wind, and UV)
Seattle’s frequent rain isn’t a problem for properly installed vinyl siding. Its water-resistant properties prevent moisture absorption, reducing the risk of rot. While it holds up well against wind, improperly installed panels can be dislodged during severe storms. UV exposure, however, poses a challenge. Modern vinyl siding often includes UV-resistant coatings to minimize fading, but extended sun exposure may still cause some color changes, especially in older or lower-grade products.
Maintenance Requirements
One of vinyl siding’s biggest perks is its low maintenance. There’s no need for painting or sealing – just a simple wash with mild soap and water to keep mold and mildew at bay. Annual checks, especially after storms, can help spot loose panels or minor damage. If needed, individual sections can be replaced without much hassle, making upkeep straightforward and affordable.
Cost Considerations
Vinyl siding offers excellent value for the money. In Seattle, installation costs typically range from $6 to $10 per square foot as of 2024. When compared to pricier options like fiber cement or metal siding, vinyl’s affordability and low maintenance make it a smart choice. For expert installation and repair services tailored to Seattle’s rainy climate, Seattle Trim Repair specializes in vinyl siding solutions, including moisture-related fixes.
3. Composite Siding
For those seeking a tough, weather-resistant siding option, composite siding provides an appealing engineered solution. Made from a mix of wood fibers and resins, this material mimics the look of natural wood while standing up to challenges like rot, warping, and pest damage – issues that often plague traditional wood siding in the Pacific Northwest.
Durability and Longevity
Composite siding is built to last, with a lifespan of 20 to 30 years. Its engineered design helps it resist swelling, warping, and rot, even in Seattle’s damp conditions. It’s also made to fend off pests like termites and woodpeckers, offering peace of mind for homeowners in the region.
Weather Resistance
Seattle’s wet climate is no match for composite siding. Its resistance to moisture absorption ensures it maintains both its appearance and structural integrity, even during extended periods of rain and high humidity. It also holds up well against strong winds and UV exposure, helping the siding retain its color and finish over time. This durability reduces the need for frequent maintenance, making it a practical choice for homes in the area.
Maintenance Requirements
Keeping composite siding in top shape is simple. Regular cleaning with water and a mild detergent, along with occasional checks of caulking and joints, is usually enough to maintain its performance.
Cost Considerations
In Seattle, the cost of composite siding installation typically ranges from $6 to $12 per square foot, depending on factors like the brand, finish, and project complexity. While the upfront expense may be higher, its durability and low maintenance needs can result in long-term savings. Well-known brands like LP SmartSide and CertainTeed are popular for their reliability and often come with extended warranties, reflecting their longevity.
For professional installation or to address moisture damage concerns, Seattle Trim Repair is a trusted local resource.
4. Cedar and Redwood Siding
Cedar and redwood siding bring a natural charm and timeless elegance to Seattle homes. Their classic Pacific Northwest look blends perfectly with the area’s lush, forested surroundings. Both types of wood are packed with natural oils and tannins, which help them resist decay, rot, and insect damage – qualities that make them a solid choice for Seattle’s wet and unpredictable weather. That said, keeping these benefits intact requires regular and careful maintenance.
Durability and Longevity
When installed correctly and maintained regularly, cedar and redwood siding can last anywhere from 20 to 40 years in Seattle’s damp climate. Cedar siding generally holds up for 20 to 30 years, while higher-grade redwood can last even longer with proper care. Cedar is particularly prized for its durability in Seattle’s weather, but it’s not entirely immune to rot if neglected. Many historic homes in the city stand as proof of how well these materials can endure, maintaining their beauty and strength for decades when properly cared for.
Weather Resistance
Seattle’s 155 rainy days a year call for siding that can handle both moisture and UV exposure. While cedar and redwood naturally resist moisture, they need sealing to prevent issues like swelling, warping, or fading from UV rays. Without adequate protection, the city’s persistent rain can lead to problems like dry rot, water damage, and mold growth, especially on untreated surfaces.
Maintenance Requirements
To get the most out of cedar and redwood siding, consistent maintenance is non-negotiable in Seattle’s wet climate. Homeowners should plan for yearly inspections to check for signs of rot or insect damage, regular cleanings to remove mildew and debris, and reapplying sealant or stain every 3 to 5 years.
Key warning signs to watch for include soft or crumbling wood, peeling paint, dark streaks, or mold patches. Addressing these issues quickly can help prevent more serious moisture damage. For those unsure about tackling these tasks, professionals like Seattle Trim Repair offer specialized services for dry rot inspections and repairs, helping homeowners catch and fix problems early.
Cost Considerations
Cedar and redwood siding come with a premium price tag. Cedar siding typically costs between $6 and $12 per square foot installed, while redwood – being the more luxurious option – ranges from $8 to $15 per square foot. On top of the initial cost, homeowners should also factor in ongoing maintenance expenses like cleaning, staining, and occasional repairs to keep the siding in top shape.
Despite the higher costs, many homeowners see these materials as worthwhile investments. Their natural beauty and rich character make them especially appealing for historic renovations and upscale custom homes, adding a distinctive touch that synthetic materials just can’t replicate.

5. Metal Siding (Aluminum and Steel)
Metal siding is a tough, low-upkeep choice for homes in Seattle. Both aluminum and steel are known for their strength, making them ideal for the Pacific Northwest’s unpredictable weather. Unlike wood, metal siding won’t rot, warp, or attract pests – key benefits in Seattle’s damp climate. This durability makes it a standout option among other sturdy materials.
Durability and Longevity
Metal siding is built to last. Steel can endure for over 40 years, offering excellent resistance to impacts, while aluminum provides decades of reliable protection. Though lighter and more prone to denting, aluminum still holds up better over time than wood or composite materials. Both options deliver long-term durability that outshines many alternatives.
Weather Resistance (Moisture, Wind, and UV)
Seattle’s constant rain is no match for metal siding. Aluminum and steel are non-porous, meaning they won’t soak up moisture like wood or fiber cement. This helps prevent mold, dry rot, and water damage. Additionally, advanced coatings shield metal siding from rust and UV rays, keeping its color and strength intact. Steel siding is particularly effective in combating the corrosive effects of salt air near Puget Sound, making it a smart pick for waterfront properties or exposed areas.
Maintenance Requirements
One of the best things about metal siding is how little maintenance it needs. A quick rinse with water now and then is usually enough to clear off dirt and debris – far easier than the regular painting, sealing, or staining that wood requires. It’s a good idea to check for scratches or dents occasionally and apply touch-up paint as needed to prevent rust. For homes with existing moisture issues or dry rot, professionals like Seattle Trim Repair can address those problems before installing metal siding, ensuring maximum protection.
Cost Considerations
Metal siding comes with a moderate to high price tag, depending on the material. Aluminum siding typically costs $6 to $12 per square foot installed, while steel ranges from $7 to $15 per square foot installed. While the upfront investment may be higher, the long-term durability and minimal upkeep make it a worthwhile choice.
| Feature | Aluminum Siding | Steel Siding |
|---|---|---|
| Cost (installed) | $6–$12/sq ft | $7–$15/sq ft |
| Durability | Good, may dent easily | Excellent, impact-resistant |
| Weight | Lightweight | Heavier |
| Maintenance | Low, occasional cleaning | Very low, occasional cleaning |
With its combination of longevity, weather resistance, and low maintenance, metal siding is an excellent option for Seattle homeowners looking for a durable and cost-effective solution.

How to Pick the Right Siding for Your Seattle Home
Selecting the best siding for your Seattle home means focusing on three main factors: durability, weather resistance, and maintenance needs. With Seattle averaging around 155 rainy days each year, the siding you choose plays a crucial role in protecting your home from moisture-related damage and avoiding expensive repairs.
Start by considering how well the siding material matches your home’s specific conditions. For example, if your house is exposed to strong winds or has areas where water tends to collect, you’ll need siding that stands up to moisture and resists issues like rot and pests. Materials like fiber cement, composite, and metal siding are excellent choices for Seattle’s damp climate, as they provide solid protection against common regional problems like water damage and decay.
Think about long-term costs, too. While vinyl siding might be less expensive to install initially, options like fiber cement often prove more economical over time due to their durability and minimal maintenance requirements.
It’s also essential to ensure that the siding you choose complies with Seattle’s building codes, particularly for moisture management, fire resistance, and wind protection. Skipping this step could lead to complications down the road.
Proper installation is just as important as the material itself. Even the highest-quality siding won’t perform well if it’s not installed correctly. Poor sealing or flashing can lead to leaks and other issues, so it’s worth hiring professionals to make sure the job is done right.
For Seattle homeowners, working with local experts like Seattle Trim Repair can make a big difference. They understand the unique challenges posed by the region’s climate and offer services such as siding installation, dry rot inspection and repair, and general exterior maintenance. Their insight ensures your siding is not only installed properly but also designed to last for decades in Seattle’s weather.
Lastly, don’t forget about regular upkeep. Scheduling periodic inspections and addressing small issues early can help extend the life of your siding and prevent expensive repairs later on. Proactive maintenance is key to keeping your home protected year after year.
