Tip: Roof area is estimated from home size using a medium pitch (5-7/12) pitch multiplier (×1.15). For an exact quote, have a contractor measure your actual roof area.

* Costs shown per sq ft of roof area. Multiply home sq ft by pitch factor to get roof area.
Average Roof Cost by Home Size (Medium Pitch, Architectural Shingles)

How We Calculate
Our roof cost calculator estimates project costs based on home size, roof pitch, and roofing material. Home square footage is converted to estimated roof area using a pitch multiplier, then material and labor costs are calculated per square foot of roof.
How the math works: Roof area = home sq ft × pitch multiplier. Material cost = roof area × material price per sq ft. Labor cost = roof area × labor rate per sq ft. Total = material + labor. Pitch multipliers: low (2-4/12) is 1.05×, medium (5-7/12) is 1.15×, steep (8-10/12) is 1.30×, very steep (11-12/12) is 1.45×.
Roofing Material Comparison
3-Tab Asphalt Shingles ($1.50–$3.00/sq ft material, $2.00–$4.00/sq ft labor) are the most budget-friendly. Flat, uniform appearance. 15–20 year lifespan. Good for cost-conscious projects.
Architectural Shingles ($2.00–$4.00/sq ft material, $2.50–$5.00/sq ft labor) are the most popular choice. Dimensional look, better wind resistance. 25–30 year lifespan. Best value for most homes.
Metal Standing Seam ($4.00–$8.00/sq ft material, $4.00–$8.00/sq ft labor) offers exceptional longevity and energy savings. 40–70 year lifespan. Lightweight, fire-resistant, and reflects heat.
Clay / Concrete Tile ($4.00–$10.00/sq ft material, $5.00–$10.00/sq ft labor) is premium and fire-resistant. 50–100+ year lifespan. Very heavy — requires structural verification.
Slate ($8.00–$16.00/sq ft material, $7.00–$14.00/sq ft labor) is the most premium natural stone roofing. 75–200 year lifespan. Requires specialized installation.
Roof Pitch & Area
Roof pitch significantly affects total area and cost. A low-pitch roof adds just 5% to home footprint, while a very steep pitch adds 45%. Steeper roofs also require additional safety equipment and take longer to install.

Frequently Asked Questions
How much does a new roof cost by home size? +
Roof cost depends on home size and pitch. A 1,500 sq ft home with architectural shingles at medium pitch costs $7,763–$15,525. Costs scale roughly linearly — a 2,000 sq ft home costs $10,350–$20,700 with the same material and pitch.
How do I estimate my roof area from home size? +
Multiply your home's footprint (sq ft) by a pitch factor: low pitch (2-4/12) × 1.05, medium (5-7/12) × 1.15, steep (8-10/12) × 1.30, very steep (11-12/12) × 1.45. A 2,000 sq ft home with medium pitch has roughly 2,300 sq ft of roof area.
What is the average cost to replace a roof in 2026? +
The average roof replacement costs $8,000–$15,000 for a typical 1,500–2,000 sq ft home with architectural shingles. Metal roofing runs $12,000–$32,000 for the same size. Prices have increased 15–20% since 2022 due to material costs.
Does roof pitch affect cost? +
Yes, significantly. Steeper roofs have more surface area (up to 45% more than the home footprint) and require additional safety equipment and labor time. A steep-pitch roof costs 15–30% more than a low-pitch roof of the same footprint.
What is the cheapest roofing material? +
3-tab asphalt shingles at $3.50–$7/sq ft are the cheapest. A 1,500 sq ft home (low pitch) costs $5,513–$11,025 with 3-tab shingles. Architectural shingles cost 20–30% more but last 10+ years longer.
How long does each roofing material last? +
3-tab asphalt: 15–20 years. Architectural shingles: 25–30 years. Metal standing seam: 40–70 years. Clay/concrete tile: 50–100+ years. Slate: 75–200 years. Higher-cost materials have significantly longer lifespans.
Is a metal roof worth the extra cost? +
Metal roofing costs 2–3× more than asphalt but lasts 2–3× longer (40–70 vs 15–30 years). It reduces cooling costs 10–25%, may qualify for insurance discounts, and has near-zero maintenance. Over a 50-year period, metal often costs less than two asphalt roof replacements.
