Seattle’s lush scenery and fresh Pacific Northwest air come at a cost: Rain, Moss, and Constant Moisture. While the climate gives the city its iconic evergreen look, it also puts a unique strain on home exteriors, especially roofs.
Choosing the Best Roofing Materials in Seattle isn’t just about appearance or cost. It’s about how well your roof can handle long periods of rain, protect against moss growth, and withstand fluctuating temperatures. At Roosevelt Roofing, we help homeowners make informed decisions when it comes to long-term roof durability and performance.
If you're planning a Roof Replacement or new build in the Seattle area, this guide will walk you through the most popular options, including an Asphalt vs. Metal Roof comparison, and other essential Roof Types to consider.
What Makes Seattle’s Climate a Challenge for Roofs?
To understand the best roofing materials for Seattle homes, you need to know what you're up against. On average, Seattle receives over 150 Rainy Days Per Year, often with high humidity, limited sunlight, and seasonal windstorms.
These climate conditions lead to:
Moss and algae growth
Water penetration and rot
Shingle deterioration
Limited roof drying time
Frequent debris from trees
These factors accelerate wear and tear, which makes material selection critical to long-term performance.
Roof Types Comparison: Pros and Cons for Seattle Homes
Let’s break down the most common Roof Types used in Seattle and how each stacks up when it comes to moisture resistance, durability, aesthetics, and cost.
The most widely used roofing material in the U.S., asphalt shingles are affordable and easy to install. They’re available in a variety of colors and textures, and many brands now include algae-resistant technology.
Pros:
Cost-effective
Quick installation
Easy to repair
Widely available
Cons:
Shorter lifespan in damp climates (15–20 years in Seattle)
Prone to moss buildup if not maintained
Can lose granules quickly in rainstorms
Best For: Homeowners on a budget or those looking for a simple solution with decent performance.

When it comes to longevity and durability, Metal Roofs are a top contender in Seattle. Standing seam metal roofs, in particular, offer sleek aesthetics with superior water-shedding capabilities.
Pros:
Lifespan of 40–70 years
Excellent for shedding rain and snow
Resistant to moss and algae
Fire-resistant and recyclable
Cons:
Higher upfront cost
Can be noisy without proper insulation
May dent from falling branches or hail
Best For: Long-term homeowners seeking low maintenance and energy efficiency.
If you’re deciding between Asphalt vs. Metal Roof materials, we’ll help you weigh the long-term value of metal in Seattle’s damp climate.
Cedar shake roofs are beautiful and natural, often seen on Seattle’s historic homes. But in a wet climate, they require vigilant care.
Pros:
Classic Pacific Northwest look
Provides good insulation
Environmentally friendly (if sourced responsibly)
Cons:
Vulnerable to mold, moss, and rot
Needs regular sealing and cleaning
Expensive to install and maintain
Best For: Homeowners focused on aesthetics and willing to maintain their roof regularly.
Less common in Seattle but still worth considering, especially for Mediterranean or Spanish-style homes.
Pros:
Long lifespan (50+ years
Fireproof and durable
Resistant to rot and insects
Cons:
Heavy—may require structural reinforcement
Expensive installation
Moss can grow in crevices without treatment
Best For: High-end builds or architecturally distinctive homes.
Slate is a premium material with unmatched longevity and a high-end appearance. While not typical in most Seattle neighborhoods, it can be found on luxury or historical homes.
Pros:
75–100+ year lifespan
Resists fire, moisture, and mold
Unique natural look
Cons:
Extremely heavy
Expensive
Requires specialized installation
Best For: High-budget projects where long-term performance and aesthetics are prioritized.
Many modern Seattle homes feature low-slope or flat roof designs, especially in newer urban builds. TPO (thermoplastic polyolefin) and EPDM (rubber membrane) are common choices for these roofs.
Pros:
Seamless waterproof protection
Reflective options improve energy efficiency
Easy to install and repair
Cons:
Vulnerable to pooling water
Requires precise installation
May tear from debris if not reinforced
Best For: Contemporary homes with flat or low-slope roofs.
When comparing Roof Types, Seattle homeowners should consider:
Metal roofs last 2–3 times longer than asphalt but come at a higher price. For long-term homeowners, the investment may pay off.
Materials like metal and treated asphalt resist organic growth better than wood or untreated shingles.
Tile, slate, and some metal options require a strong roof frame. We'll inspect your structure before recommending heavy materials.
Reflective coatings on metal or TPO roofs can help reduce cooling costs during the warmer months.
Choose a material that complements your home’s architectural style and your neighborhood’s visual guidelines.
Even the best roofing materials in Seattle need proper maintenance. Here’s how to extend the life of your roof:
Annual Inspections: Schedule a yearly checkup, especially after major storms.
Gutter Cleaning: Keep gutters clear to prevent water backup.
Moss Treatment: Use zinc strips or moss-killing solutions every 1–2 years.
Trim Overhanging Branches: Prevent damage and reduce moisture retention.
Address Issues Early: Don’t wait to fix a leak or curling shingles.

When it comes to Roof Types Comparison, we often recommend:
Asphalt shingles for budget-conscious homeowners planning to move within 10–15 years.
Metal roofing for homeowners who want long-term protection and low maintenance.
Flat roof systems (TPO/EPDM) for modern, low-slope builds in urban areas.
Cedar shake or slate for high-end homes seeking premium looks with proper upkeep.
Whatever material you choose, our goal is to ensure your roof performs for years to come, through every rainy season and Seattle storm.
