Metal Roofing vs Asphalt Shingles

Banner Elk, NC

Which Is Better for Morganton, Valdese & Granite Falls?

Morganton, Valdese, and nearby Granite Falls sit in the foothills of the Blue Ridge Mountains. The climate is humid-subtropical: hot, sticky summers and moderately cold winters, with around 48 inches of annual rainfall and about 4–5 inches of snow (bestplaces.net). That means roofs face heavy summer storms, sunny days, and occasional freeze-thaw cycles. Here’s how two popular options—metal roofing and asphalt shingles—stack up for your area.


1. Upfront Cost

  • Metal Roofing
    • Premium product: typically $7–$12 per sq ft installed. High-end metal (like standing seam) can run even higher.
    • Longer lifespan (40–70 years) helps offset cost over time.
  • Asphalt Shingles
    • Budget-friendly: $3–$6 per sq ft installed for good-quality architectural shingles.
    • Basic 3-tab shingles are cheaper but don’t last as long.

Verdict: Asphalt shingles are easier on the wallet upfront. Metal costs more but recoups value with longevity.


2. Durability & Lifespan

  • Metal Roofing
    • Extremely durable. With winds common in North Carolina’s summer storms, metal can resist wind speeds up to 140 mph.
    • Non-porous surface sheds rain, snow, and ice efficiently.
    • Common warranties extend 30–50 years; actual lifespan often exceeds that.
  • Asphalt Shingles
    • Typical lifespan is 15–25 years, depending on quality and maintenance.
    • High winds may lift shingles or blow off edges over time.
    • Heat and humidity may lead to algae growth or granule loss.

Verdict: Metal clearly wins durability, with longer life and resilience to local weather extremes.


3. Appearance & Aesthetics

  • Metal Roofing
    • Sleek, modern look; available in panel styles (standing seam) or metal shingles designed to mimic classic materials.
    • Wide color range, but color-fade over decades is possible—though most manufacturers provide strong paint warranties.
  • Asphalt Shingles
    • Traditional look, with architectural variants offering dimensional appeal.
    • Easier to match with local home styles—especially Craftsman, Colonial, or Cape Cod designs.
    • Granules protect from UV; colors are bold but may fade after ~10 years.

Verdict: For contemporary or rural-modern homes, metal is visually striking. For traditional curb appeal, shingles often blend more appropriately.


4. Suitability for Local Climate

  • Metal Roofing
    • Excellent water runoff helps during heavy April–July rains .
    • Prevents ice dams in winter due to heat conduction and smooth surface.
    • Reflective coatings can reduce cooling costs during hot, humid summers.
  • Asphalt Shingles
    • Good at insulating and resisting rain, though granule wear can expose the mat below.
    • Shingle overlap handles moderate snow but can be vulnerable to freeze-thaw cycles.
    • Heat and humidity can accelerate aging—proper attic ventilation helps.

Verdict: Metal’s performance edge in wet, variable weather makes it ideal for this region. Shingles work well too but demand more upkeep to stay healthy.

🏠 Which One Should You Choose?

  • Go with Metal Roofing if:
    You plan to stay in your home long‑term and want a long‑lasting, low‑maintenance roof that handles heavy rain, snow, and wind with ease. Ideal for modern-style homes or if you want to boost resale value with a premium look.
  • Stick with Asphalt Shingles if:
    You’re working with a tighter budget, own a traditional-style home, or don’t mind planning for roof replacement in 15–25 years. Simple, reliable, and familiar to most homeowners.

Final Thoughts

For Morganton, Valdese, and Granite Falls homeowners facing high humidity, frequent storms, and occasional snowfall, metal roofing offers superior durability and climate resilience, though at a higher price point. Asphalt shingles remain a solid, cost‑effective choice for traditional homes and homeowners more concerned with upfront cost than long-term lifespan.
