Metal Roofing

The Ultimate Guide to 50+ Year Roofing Systems

Why Metal Roofing Dominates in Fraser Valley

Drive through Hope, Harrison Hot Springs, or the hillsides of Mission, and you'll see an increasing number of metal roofs. This isn't a trend — it's homeowners making informed decisions about long-term value, performance in extreme weather, and total cost of ownership.

Metal roofing costs 2-3x more upfront than asphalt shingles. But it lasts 2-3x longer, requires virtually no maintenance, and outperforms shingles in every measurable category: wind resistance, snow shedding, fire protection, and energy efficiency.

This guide explains everything you need to know to make an informed decision about metal roofing.

Types of Metal Roofing Systems

1. Standing Seam Metal Roofing (Premium Residential)

What It Is:

Vertical panels with raised seams (ribs) that interlock and are mechanically seamed together. Fasteners are concealed beneath the seams, creating a clean appearance and eliminating exposed screw penetrations.

Construction:

  • Panel Width: Typically 12-18 inches
  • Seam Height: 1-2 inches above panel surface
  • Fastening: Concealed clips allow thermal expansion/contraction
  • Lengths: Custom-cut to exact roof measurements (no horizontal seams)

Performance:

  • Lifespan: 50-70+ years in Fraser Valley
  • Wind Rating: 150+ mph (engineered systems)
  • Fire Rating: Class A (non-combustible)
  • Snow Shedding: Excellent (smooth surface, steep seams)
  • Maintenance: Virtually none

Cost:

  • 24-gauge steel, Kynar 500 finish: $25,000-35,000 (average home)
  • Aluminum: $30,000-40,000
  • Copper: $60,000-100,000+

Our Recommendation: Standing seam is the gold standard for residential metal roofing. If you can afford the upfront cost and plan to stay in your home 10+ years, it's the best long-term investment.

2. Exposed-Fastener Metal Panels (Agricultural/Budget)

What It Is:

Corrugated or ribbed panels fastened directly through the panel face with exposed screws. Common profiles include R-panel, PBR (Purlin Bearing Rib), and traditional corrugated.

Construction:

  • Panel Width: 24-36 inches
  • Rib Height: 3/4 to 1-1/4 inches
  • Fastening: Screws with neoprene washers penetrate panel face
  • Lengths: Stock lengths or custom-cut

Performance:

  • Lifespan: 30-40 years (fastener washers are the weak point)
  • Wind Rating: 90-120 mph (depends on fastener spacing)
  • Fire Rating: Class A
  • Snow Shedding: Good (but screws create friction points)
  • Maintenance: Fastener inspection/replacement every 15-20 years

Cost:

  • Galvanized steel: $8,000-12,000 (average home)
  • Painted steel: $10,000-15,000

Our Recommendation: Exposed-fastener panels are excellent for agricultural buildings, shops, and budget-conscious residential projects. They're 50-60% cheaper than standing seam but require eventual fastener maintenance.

Material Comparison: Steel vs. Aluminum vs. Copper

Steel (Our Standard Recommendation)

Gauges:

  • 24-gauge: Our standard (0.024" thick) — best balance of strength and cost
  • 26-gauge: Thinner (0.019") — adequate for most applications, lower cost
  • 29-gauge: Thin (0.015") — budget option, more prone to denting

Coatings:

  • Galvanized (G-90): Zinc coating, no paint — $$ (agricultural use)
  • Galvalume: Aluminum-zinc coating — $$$ (better corrosion resistance)
  • Painted (SMP): Silicone-modified polyester — $$$ (25-year paint warranty)
  • Kynar 500 (PVDF): Premium fluoropolymer — $$$$ (40-year paint warranty)

Strengths:

  • Excellent strength-to-weight ratio
  • Wide color selection
  • Cost-effective
  • Proven performance in Fraser Valley

Considerations:

  • Can rust if coating is damaged (rare with Galvalume + paint)
  • Expands/contracts with temperature (requires proper clip system)

Aluminum

Strengths:

  • Corrosion-proof (ideal for coastal areas)
  • Lightweight (easier installation on older structures)
  • Doesn't rust

Considerations:

  • Softer than steel (more prone to denting)
  • 20-30% more expensive than steel
  • Limited color options
  • Expands/contracts more than steel

Our Recommendation: Aluminum makes sense for coastal properties (salt air corrosion) or historic buildings where weight is a concern. For inland Fraser Valley, steel is the better value.

Copper

Strengths:

  • Unmatched longevity (100+ years)
  • Beautiful patina development
  • Corrosion-proof
  • Prestige/luxury appeal

Considerations:

  • Extremely expensive ($60,000-100,000+ for average home)
  • Requires specialized installation
  • Patina may not suit all aesthetics
  • Overkill for most residential applications

Our Recommendation: Copper is for heritage buildings, luxury homes, or customers who want a roof that outlasts them. For 99% of homeowners, steel is the smarter choice.

Why Metal Outperforms Asphalt in Fraser Valley

1. Snow Shedding (Critical in Hope, Harrison)

Fraser Valley's "Cascade concrete" snow is heavy and wet. A 12-inch snowfall can deposit 2,000+ pounds per square on a roof. Metal's smooth surface and steep seams allow snow to slide off naturally, preventing ice dams and structural stress.

Asphalt Shingles: Rough granule surface grips snow. Ice dams form at eaves. Requires manual snow removal in extreme events.

Metal Roofing: Snow slides off within days of snowfall. Ice dams are rare (proper eave flashing prevents the few that form).

2. Wind Resistance (Critical in Hope)

Hope's wind shear from converging mountain passes regularly exceeds 100 km/h. Metal roofing's mechanical fastening and interlocking seams provide superior wind resistance.

Asphalt Shingles: Rely on adhesive strips and nails. Wind can lift edges and tear shingles off. Even our 6-nail protocol has limits.

Standing Seam Metal: Engineered to 150+ mph. Concealed clip systems prevent wind uplift. We've never had a metal roof fail in a windstorm.

3. Moss/Algae Resistance (Critical in Agassiz, Tree-Shaded Areas)

Metal's non-porous surface doesn't support moss or algae growth. Asphalt shingles' granular surface retains moisture and organic debris.

Asphalt Shingles: Require periodic cleaning, zinc strips, or algae-resistant granules. Moss growth is inevitable in shaded areas.

Metal Roofing: Virtually maintenance-free. Rain washes surface clean. No moss treatment needed.

4. Fire Resistance (Critical in Wildfire Interface Areas)

Fraser Valley's interface with forest lands creates wildfire risk. Metal roofing is non-combustible.

Asphalt Shingles: Class A fire rating (best available for shingles), but still combustible under extreme heat.

Metal Roofing: Non-combustible. Won't ignite from embers or radiant heat. Provides superior protection in wildfire events.

The Total Cost of Ownership Analysis

Metal roofing's upfront cost scares many homeowners. But total cost of ownership tells a different story:

Asphalt Shingles (50-Year Ownership):

  • Initial Installation: $6,000 (IKO Cambridge)
  • Replacement #1 (Year 25): $8,000 (inflation-adjusted)
  • Moss Treatment: $300 every 3 years x 16 treatments = $4,800
  • Minor Repairs: $500 every 10 years x 5 = $2,500
  • Total 50-Year Cost: $21,300

Standing Seam Metal (50-Year Ownership):

  • Initial Installation: $30,000 (24-gauge steel, Kynar 500)
  • Replacement: $0 (roof lasts 50-70+ years)
  • Moss Treatment: $0 (no moss growth)
  • Minor Repairs: $0 (virtually maintenance-free)
  • Total 50-Year Cost: $30,000

The Difference: $8,700 over 50 years. Metal roofing costs 40% more over a lifetime, but provides:

  • Zero maintenance hassle
  • Superior performance in all weather conditions
  • No replacement disruption at year 25
  • Increased home resale value
  • Energy savings (reflective surface)

For many homeowners, that's worth it.

When Metal Roofing Makes Sense

You Should Strongly Consider Metal If:

  • You're in Hope, Harrison Hot Springs, or other extreme weather zones
  • You plan to stay in your home 15+ years
  • You have a steep roof (metal's snow shedding is a major advantage)
  • You're tired of moss treatment and maintenance
  • You value long-term performance over upfront cost
  • You're building new construction (easier to budget metal from the start)

Asphalt Shingles Might Be Better If:

  • You're selling your home in 5-10 years (won't recoup metal's premium)
  • You have strict budget constraints
  • You prefer traditional shingle aesthetics
  • You're in a low-risk climate zone (Abbotsford, flat areas)

The Bottom Line

Metal roofing isn't for everyone. But for Fraser Valley homeowners in extreme weather zones, those planning long-term ownership, or anyone tired of roofing maintenance, it's the best investment you can make.

We install both asphalt and metal. We have no bias. We just want you to make an informed decision based on your specific situation, budget, and goals.
