Roofing Materials Comparison: Asphalt vs. Metal vs. Cedar
Roofing Doctors Knowledge Base
Choosing a roofing material is one of the most significant decisions in a roof replacement project. This comparison covers the three most common residential choices for Massachusetts and Rhode Island homes across the criteria that matter most.
At-a-Glance Comparison
| Feature | Architectural Asphalt | Standing Seam Metal | Cedar Shake |
|---|---|---|---|
| Installed Cost (2,000 sq ft) | $12,000-$18,000 | $24,000-$40,000 | $25,000-$40,000 |
| Expected Lifespan (MA) | 25-35 years | 50-70 years | 25-40 years (with maintenance) |
| Maintenance | Low | Very Low | High |
| Ice/Snow Performance | Good (with proper install) | Excellent | Good |
| Wind Resistance | Good-Excellent | Excellent | Good |
| Aesthetics | Versatile | Modern/Classic | Rustic/Natural |
| Warranty | 30-50 years (GAF/CT) | Varies by product | Limited |
| Fire Rating | Class A (fiberglass) | Class A | Class C-A (varies with treatment) |
| Eco-Friendly | Moderate | High (recyclable) | Highest (natural, renewable) |
Asphalt Shingles
The Case For
Asphalt architectural shingles are the dominant choice for Massachusetts homes for good reason - they offer the best combination of cost, performance, and availability. The selection of colors, profiles, and warranty options is extensive. GAF Master Elite and CertainTeed ShingleMaster contractors can provide warranty coverage up to 25-50 years on workmanship.
Performance in New England
Modern architectural shingles perform well in New England when properly installed. Key specifications to look for:
- •Class F (110 mph) or Class H (150 mph) wind rating
- •Algae-resistant (AR) granules for New England's humidity
- •SBS-modified ("impact resistant" or "flex") compounds for cold-temperature flexibility
The Limitations
Asphalt is not a "forever" material. A 30-year shingle in ideal conditions may last only 22-28 years in New England's demanding climate. And unlike metal, asphalt shingles go to landfill when they're replaced (though some recycling programs exist).
Best For
- •Most Massachusetts and Rhode Island residential applications
- •Budget-conscious projects with strong warranty priorities
- •Homeowners who may sell within 10-20 years
- •Any situation where upfront cost is the primary constraint
Standing Seam Metal Roofing
The Case For
Metal roofing's fundamental advantage in New England is longevity - a quality standing seam metal roof installed today will likely be the last roof the current owner ever needs. Its snow-shedding performance dramatically reduces ice dam risk, and its concealed fastener design (no exposed screws) eliminates the most common metal roof leak point.
Performance in New England
This is where metal truly excels. Snow slides off smooth metal surfaces rather than accumulating, significantly reducing winter snow loads and virtually eliminating ice dam formation. Metal also outperforms asphalt in coastal salt air environments when aluminum or PVDF-coated Galvalume is specified.
The Limitations
Metal's premium is real. Standing seam costs 2-3x more than architectural asphalt upfront. Installation requires specialized crews with specific training. For homeowners who won't stay in the home long enough to realize the long-term value (10-15+ years), the premium is harder to justify.
Best For
- •Homeowners planning 15+ year ownership
- •Coastal properties where salt air accelerates asphalt degradation
- •Homes with ice dam history (metal eliminates the problem)
- •Owners seeking the highest-quality, lowest-maintenance result
- •Contemporary architecture where metal aesthetics are preferred
Cedar Shake
The Case For
Cedar shake is the most authentically New England choice - beautiful, natural, and historically appropriate for the region's architecture. On a historic home or in a neighborhood with architectural character standards, cedar may be the right material aesthetically even at a cost premium.
Performance in New England
Cedar's biggest challenge in Massachusetts and Rhode Island is the same as its biggest strength - it's natural wood. Wood breathes, insulates naturally, and weathers beautifully - but also absorbs moisture, supports moss growth in humid conditions, and requires active maintenance that most homeowners underestimate.
In heavily shaded, north-facing applications, or for homeowners unwilling to commit to the maintenance program, cedar often disappoints compared to its potential.
The Limitations
Cedar is the most maintenance-intensive choice. Every 5-7 years, professional cleaning and treatment is required to achieve the material's potential lifespan. Skipping treatments shortens cedar's life dramatically. Cedar also typically requires Class B or C fire ratings (or Class A with pressure treatment) in Massachusetts residential applications.
Best For
- •Historic or period-appropriate architecture
- •Homeowners committed to the maintenance program
- •Properties where natural aesthetics are paramount
- •Replacement of an existing cedar roof on a home where cedar was original
Making Your Decision
The right material depends on your specific situation:
**Choose asphalt if:** Budget is the primary driver, you want the best warranty protection per dollar spent, or you're planning to sell within 15 years.
**Choose metal if:** You're committed to long-term ownership, your home has ice dam issues, you're in a coastal location, or you want the lowest lifetime cost and lowest maintenance.
**Choose cedar if:** Architectural authenticity matters deeply to you, you're replacing an existing cedar roof, and you're genuinely committed to the maintenance program.
Consider also: synthetic alternatives to cedar (CeDUR, Brava) provide cedar's aesthetics with significantly lower maintenance requirements and longer lifespans. Worth exploring if you love the look but not the maintenance.
