How Much Does a New Roof Cost?
Roof replacement costs depend on three main factors: your roof’s size, the pitch (steepness), and the materials you choose. Here’s what to expect:
Why roof size matters most
Materials and labor are priced per “roofing square” (100 sq ft). A roof that’s 200 sq ft larger than you thought means 2 extra squares – potentially $400-800 more in materials alone. Get your exact roof size before requesting quotes.
Roof Replacement Cost by Material
The roofing material you choose has the biggest impact on your total cost. Here’s what each option costs, installed:
| Material | Cost per Sq Ft | 2,000 Sq Ft Roof | Lifespan |
|---|---|---|---|
| 3-Tab Asphalt | $3.50 – $5.50 | $7,000 – $11,000 | 15-20 years |
| Architectural Shingles | $4.50 – $8.50 | $9,000 – $17,000 | 25-30 years |
| Metal Roofing | $7.00 – $14.00 | $14,000 – $28,000 | 40-70 years |
| Wood Shake | $8.00 – $14.00 | $16,000 – $28,000 | 25-30 years |
| Slate | $15.00 – $30.00 | $30,000 – $60,000 | 75-100+ years |
| Clay/Concrete Tile | $10.00 – $18.00 | $20,000 – $36,000 | 50-100 years |
What Most Homeowners Choose
Architectural asphalt shingles are the most popular choice, striking a balance between cost, durability, and appearance. They come in many colors, resist wind and algae, and typically last 25-30 years with proper installation.
How Roof Pitch Affects Cost
Steeper roofs cost more to replace. Why? They require more safety equipment, take longer to work on, and have higher waste factors when cutting materials.
| Roof Pitch | Difficulty | Cost Impact |
|---|---|---|
| 4/12 or less | Walkable | Standard pricing |
| 5/12 to 7/12 | Moderate | +10-15% |
| 8/12 to 10/12 | Steep | +15-25% |
| 11/12 or higher | Very Steep | +25-50% |

How long does a roof replacement take?
Most residential roof replacements take 1-3 days. A simple 2,000 sq ft roof with asphalt shingles can often be done in a single day by a 4-6 person crew. Larger roofs, steep pitches, or complex designs (multiple valleys, dormers) may take 3-5 days.
Should I get multiple quotes?
Yes, we recommend getting 3-5 quotes. This helps you understand the price range in your area and compare what’s included. Before getting quotes, use our free roof report to know your roof size – any reputable contractor should quote within 5% of your actual measurements.
Can I roof over existing shingles?
In some cases, yes – but it’s not recommended. Roofing over (called a “nail-over”) costs less upfront but can void warranties, hide damage, and shorten the new roof’s lifespan. Most quality contractors will recommend a full tear-off.
Does insurance cover roof replacement?
Homeowner’s insurance typically covers roof damage from storms, hail, or fallen trees – but not wear and tear. If you have storm damage, document it with photos and your roof report before filing a claim. The insurer will send an adjuster to verify.
What’s the best time of year to replace a roof?
Late spring through early fall is ideal – shingles need warm weather (40-85°F) to seal properly. However, roofing can be done year-round in most climates. Off-season (winter) may offer lower prices since contractors are less busy.
How do I know if I need a full replacement vs. repairs?
Consider replacement if: your roof is over 20 years old, you have multiple leaks, more than 25% of shingles are damaged, or you’re seeing granules in gutters. For localized damage (a few missing shingles), repairs are usually sufficient and much cheaper.
