Asphalt Shingles vs. Metal Roofing

Asphalt Shingles vs. Metal Roofing: Which is Better for WA Homes?

Choosing between asphalt shingles or metal roofing in Washington? HB Roofing compares cost, durability, maintenance, and style to help you make the best choice. When it’s time for a new roof, one of the biggest decisions homeowners faces is which material to choose. For most homes in Washington, the two most popular options are:

  • Asphalt shingles – classic, affordable, and versatile.
  • Metal roofing – durable, modern, and long-lasting.

At HB Roofing & General Construction, we’ve installed both across the Seattle area. Here’s our breakdown of how they compare, especially for Washington’s wet, moss-prone climate.

Asphalt Shingles: The Popular Choice

Asphalt shingles remain the most common roofing material in the U.S. — and for good reason.

Advantages of Asphalt Shingles

  • Affordable upfront cost – Lower installation cost compared to metal.
  • Wide style variety – Available in many colors and textures, including architectural shingles.
  • Easier repairs – Damaged shingles can be replaced individually.
  • Good performance for 20–30 years when properly installed and maintained. Annual roof inspections can help extend the life of your shingles. Click here for a Free Roof Inspection. 
  • Manufacturer warranties – Premium shingles (like CertainTeed Landmark®) offer algae resistance, impact ratings, and Class A fire protection.

Considerations of Asphalt Shingles

  • Shorter lifespan compared to metal.
  • Can be prone to moss and algae growth in Washington’s damp climate (though CertainTeed’s
    StreakFighter® helps).
  • Heavier maintenance over the years.

Metal Roofing: The Long-Term Investment

Metal roofing has grown in popularity, especially in the Pacific Northwest, thanks to its durability and sleek look.

Advantages of Metal Roofing

  • Exceptional longevity – Lasts 40–50 years or more.
  • Superior durability – Resistant to wind, fire, and impact.
  • Great for Washington weather – Sheds rain, snow, and moss better than shingles.
  • Energy efficiency – Reflects sunlight, helping lower cooling costs in summer.
  • Eco-friendly – Often made from recycled materials and recyclable at end of life.

Considerations of Metal Roofing

  • Higher upfront cost than asphalt shingles.
  • Noise factor – Rain and hail can be louder (though underlayment helps).
  • Style preference – Some homeowners prefer the traditional look of shingles.

Cost Comparison

Every home and project are unique, but here’s what many homeowners in Washington can expect to invest in a new roof:

  • Asphalt Shingles – Average cost ranges from $8,000 – $15,000+ for most homes.
  • Metal Roofing – Average cost ranges from $15,000 – $30,000+, depending on the roof’s style and size.

While metal roofing costs more upfront, it can last twice as long as shingles, which makes it a better long-term investment. 

These are average estimates. Your total project cost will vary based on roof design, materials, and personal preferences. Our team will provide a clear, customized quote so you know exactly what to expect.

Frequently Asked Questions

Q: How long do asphalt shingles last in Washington?

In Washington’s climate, asphalt shingles typically last 20–30 years, depending on the shingle quality, installation, and regular maintenance. Premium shingles often provide longer protection, with added resistance against algae growth, heavy rain, and storm damage—common challenges in our region.

Q: Does moss grow on metal roofs?

Moss growth is much less common on metal roofs than on asphalt shingles. Metal’s smooth surface makes it harder for moss, algae, and debris to take hold. This makes metal roofing a great choice for Washington’s damp climate, where moss is a frequent issue for shingle roofs.

Q: Is metal roofing noisy in rain?

While older metal roofs had a reputation for being noisy, today’s installations include modern underlayment and insulation that greatly reduce sound. Most homeowners report little to no difference in rain noise compared to asphalt shingles.

Q: Can I install metal roofing over my shingles?

In some cases, yes—it’s possible to install metal roofing over existing shingles. However, it depends on your roof’s structure, condition, and local building codes. At HB Roofing, we carefully evaluate each home to determine whether this approach is safe, efficient, and the best long-term solution.

Q: Which roof adds more resale value?

Both options can increase your home’s value, but in different ways. Metal roofs often provide a stronger resale boost because of their exceptional longevity, energy efficiency, and low maintenance. However, architectural shingles also remain highly attractive to buyers, offering great curb appeal at a lower upfront cost. The best choice depends on your budget, home style, and long-term plans. Our team at HB Roofing can walk you through both options to help you choose the one that adds the most value for your home.
