Tue Aug 12Last winter in Redmond, a homeowner told us, “I never thought my roof could make my allergies worse—until I replaced it.”
For many Redmond residential roofing clients we work with, a roof isn’t just about curb appeal—it’s the first line of defense for your health. And as more homeowners look for eco-conscious solutions, one question keeps coming up: What’s the healthiest roofing material I can install?
Time and again, the answer is the same: a metal roof.
In this in-depth guide, we’ll explain why metal roofing is the safest and most sustainable option for your roof replacement—and how premium systems from Nu-Ray Metals and Duro-Last set the standard in the PNW.
Why Roof Materials Matter: Health Starts at the Top
When people think about healthy homes, they often focus on indoor air quality, flooring, or paint. But few realize that roofing materials can directly impact your health.
Many traditional roofs—especially asphalt shingles—are made using petroleum-based compounds and synthetic chemicals. Over time, these materials undergo a process called off gassing, where volatile organic compounds (VOCs) are slowly released into the air.
These VOCs can contribute to:
- Respiratory irritation
- Allergic reactions
- Headaches and fatigue
- Hormonal disruption with long-term exposure
This issue is exacerbated in warmer months when heat increases the rate of off gassing, and in damp climates like Redmond and Bellevue where mold and mildew thrive on traditional roof surfaces. Additionally, deteriorating shingles can introduce airborne particles, mold spores, and chemical residue into your attic and ventilation system. That means the material sitting on your roof may eventually affect the air you breathe inside your home.
We saw this firsthand with a Bellevue family near Lake Sammamish whose child had persistent asthma symptoms. Their attic showed signs of shingle dust and mold intrusion. After replacing their roof with a Nu-Ray aluminum standing seam (installed by our Redmond metal roofing team), the mold issue stopped—and within months, they reported fewer allergy flare-ups.
To learn more about the impact of roofing materials on indoor air quality and VOCs, see this public article from the New York State Department of Health.
Why Choose Metal Roofing in Redmond’s Climate: The Health-Conscious Choice
Unlike asphalt, metal roofs do not contain VOCs. They don’t rely on bitumen, fiberglass, or adhesives that emit toxins. Once installed, a metal roof is inert—meaning it won’t off gas, degrade chemically, or emit any fumes over time.
Key Health Benefits of Metal Roofing:
- Zero off gassing
- Naturally resistant to moss, mold, and mildew (no spore release into your vents)
- Free from flame-retardant additives and adhesives
- Does not harbor pests or deteriorate into dust particles
- Improved ventilation with reflective coatings that reduce indoor heat buildup
If you’re sensitive to chemicals or are seeking a safer living space for children, aging parents, or pets, a metal roof is one of the cleanest materials you can install.
Sustainable Metal Roofing in Redmond and the PNW
Sustainability is another critical factor. Roofing waste accounts for millions of tons of landfill waste in the U.S. every year. Most asphalt shingles last 15–25 years before they’re torn off and replaced. In contrast, metal roofs can last 50+ years and are 100% recyclable at the end of their lifespan.
Environmental Advantages of Metal Roofs:
- Made from 30%–95% recycled content
- 100% recyclable with no need for landfill disposal
- Reflective coatings help reduce urban heat islands and cooling costs
- Fewer replacement cycles = reduced raw material demand
- Compatible with solar panels and rainwater harvesting systems
A Kirkland homeowner recently made the switch from cedar shake to stainless steel standing seam. They also installed a rainwater catchment system for their garden, knowing the water would be cleaner without asphalt residue. Now, their roof not only looks sharp but also supports their sustainability goals year-round.
Eco-Friendly Metal Roof Options
1. Recycled Aluminum Roofing
- Made from 100% recyclable aluminum, often with high recycled content
- Lightweight and highly corrosion-resistant—ideal for Washington’s wet climate
- Durable with a lifespan of 40–70 years and fully recyclable at end-of-life
2. Stainless Steel Standing-Seam Roofing
- Extremely durable and corrosion-resistant—more so than many metals
- Long lifespan of 100+ years; recyclable with minimal embodied energy
- Excellent for longevity-focused, low-impact installations
3. Copper Standing-Seam Roofing
- Virtually maintenance-free and highly recyclable
- Develops a protective patina that enhances longevity
- Can last centuries and performs well in environmental life-cycle metrics
These materials are particularly well-suited for eco-conscious homeowners across the PNW who value performance, aesthetics, and long-term sustainability.

Common Questions About Metal Roofing in Redmond
Despite all their benefits, some homeowners hesitate to switch to metal. Let’s clear up the most common concerns:
Can metal roofs withstand PNW windstorms?
Yes — and we’ve seen them hold up in some serious weather. Our standing seam systems are engineered to resist high winds, with ratings up to 120 mph. That’s more than enough to handle most of the gusty storms that roll through the PNW. Plus, our installation process ensures panels are securely fastened for maximum durability.
What is the lifespan and return on investment compared to shingles?
Most asphalt shingle roofs last 15–25 years. The metal roofs we install typically last 40–70 years — and some premium options can go well past that. When you spread that longevity over decades, plus the savings on repairs and maintenance, the return on investment is far greater than with shingles
How do metal roofs perform in Seattle’s rainy, wet climate?
At Landmark Roofing & Siding, we’ve installed metal roofs all across the Eastside and the greater Seattle area, and they’re built for our weather. The interlocking panels and premium protective coatings shed water fast, resist moss growth, and minimize leaks—even during weeks of constant rain. Many of our customers in Redmond and Bellevue have told us they love how much cleaner their roof stays compared to asphalt.
What should I know about warranties and choosing the right contractor?
💡 Landmark Roofing’s Lifetime Warranty Advantage
This is a big one. Manufacturer warranties typically cover paint and finish defects, while workmanship warranties cover installation quality. At Landmark Roofing & Siding, we go further with a lifetime craftsmanship warranty that’s fully transferable to a new homeowner for 20 years — a huge selling point if you ever decide to sell your home. Plus, we’re certified installers for both Nu-Ray Metals and Duro-Last Roofing Systems, meaning your roof is installed to exact manufacturer specifications for maximum performance and protection.Are metal roofs environmentally friendly?
Absolutely. The systems we install are made with up to 95% recycled content and are fully recyclable at the end of their lifespan. Many of our clients in Kirkland and Sammamish choose metal roofing specifically because it aligns with their sustainability goals — and it looks great doing it.
Can a metal roof help reduce my energy costs?
Yes. Our metal roofing systems come with reflective coatings that reduce heat absorption, keeping your attic cooler in the summer and improving energy efficiency all year long. In the past two years, we’ve had multiple clients tell us their summer cooling bills dropped after switching to metal.
