Key Cost Factors
Several factors influence the total cost of your roof replacement:
- •Roofing material: Asphalt shingles vs. metal vs. tile can double or triple costs
- •Roof size & complexity: More square footage and complex designs increase material and labor
- •Roof slope (pitch): Steeper roofs require more safety equipment and time
- •Location & labor costs: Clark County rates vary by contractor and season
- •Height & accessibility: Multi-story homes or difficult access add costs
- •Removal & repairs: Tear-off and decking replacement can add $2-$5 per sq ft
Roof Replacement Cost by Material
Your choice of roofing material is the single biggest driver of total project cost. Here's a comparison of popular options in Washington state:
| Material | Cost/100 Sq Ft | Total Range (2,000 sq ft) | Notes |
|---|---|---|---|
| Asphalt Shingles | $650 - $1,150 | $13,000 - $23,000 | Most popular; 20-40 years lifespan; great value |
| Metal Roofing | $1,170 - $1,820 | $23,400 - $36,400 | 40-70 year lifespan; energy efficient; low maintenance |
| Tile Roofing | $1,300 - $2,340 | $26,000 - $46,800 | 50+ year lifespan; premium aesthetics; very durable |
Asphalt Shingle Options
Not all asphalt shingles are created equal. Here's how the three main types compare:
3-Tab Shingles
Budget-friendly option with flat, uniform appearance.
- Cost: $500-$600/100 sq ft
- Lifespan: 15-20 years
- Warranty: 20-25 years
- Best for: Budget-conscious homeowners
Note: No longer installed due to poor performance
Architectural Shingles
Premium dimensional look with enhanced durability.
- Cost: $650-$950/100 sq ft
- Lifespan: 25-30 years
- Warranty: 30-50 years
- Best for: Most homeowners (best value)
Premium Shingles
Luxury appearance with maximum protection.
- Cost: $1,050-$1,200/100 sq ft
- Lifespan: 30-50 years
- Warranty: Lifetime limited
- Best for: High-end homes
Labor Costs
Labor typically accounts for 30-50% of your total roof replacement cost. In Clark County, professional roofing crews charge between $195-$575 per square (100 sq ft) for installation, depending on the material and complexity.
Factors affecting labor rates include material type (asphalt vs. tile vs. metal), crew size and experience, roof accessibility and height, roof pitch (steeper = higher cost), time of year (spring/summer peak season), and permit requirements.
How Roof Size, Height & Pitch Affect Cost
Larger roofs require more materials and labor hours. Roof pitch (slope) also significantly impacts cost—steeper roofs are more dangerous and time-consuming to work on.
Cost by Home Size (Asphalt Shingles)
- 1,000 sq ft: $6,500 - $11,500
- 1,500 sq ft: $9,750 - $17,250
- 2,000 sq ft: $13,000 - $23,000
- 2,500 sq ft: $16,250 - $28,750
- 3,000 sq ft: $19,500 - $34,500
Pitch Impact
- Low pitch (2:12 - 5:12): Standard pricing
- Medium pitch (6:12 - 8:12): +10-15% cost
- Steep pitch (9:12+): +20-40% cost
- Multi-story homes: Additional safety equipment adds 15-25%
Roof Removal & Disposal Costs
Removing your old roof (tear-off) typically costs $100-$200 per square (100 sq ft), or about $2,000-$4,000 for a 2,000 sq ft roof.
Removal costs by material: Asphalt shingles ($100-$150 per square), Metal roofing ($125-$175 per square), Tile roofing ($150-$200 per square).
Note: Some codes allow "reroofing" (installing over old shingles) to save on tear-off costs, but we generally recommend full removal to inspect decking and ensure proper installation.
Additional Roof Components & Costs
A complete roof replacement includes more than just shingles. These components may add to your total:
Decking Replacement
$50-$100 per sheet if plywood is damaged or rotting
Underlayment
$50-$100 per square for synthetic or felt underlayment
Ice & Water Barrier
$100-$200 for valleys and eaves protection
Fascia & Soffits
$6-$20 per linear foot if replacement needed
Flashing
$15-$25 per linear foot for chimney, valley, and wall flashing
Pipe Boots & Vents
$20-$50 each for replacement boots and seals
