Quick answer
A complete roofing quote combines material, labor, tear-off, disposal, permits, and accessories. For a typical asphalt shingle roof in 2026 that totals about $4.50–$11 per square foot, or roughly $9,000–$22,000 for a 2,000 sq ft roof. Line-item quotes (material vs. labor vs. tear-off) let you compare bids accurately instead of one blended price.

How to Calculate Roofing Quote Calculator Manually
Step 1: Pin Down the Verified Roof Area
Never price from house sq ft. Get sloped roof surface from a plane-by-plane takeoff, aerial measurement, or pitch-corrected footprint. Wrong area is the #1 budget error.
Step 2: Choose Unit Rates from Current Quotes
Material cost per square (100 ft²) and labor cost per square change with markets and material types. Asphalt labor often runs $50–$120/sq; premium materials like slate or metal can be $200–$400+/sq installed.
Step 3: Add Accessory and Fixed Line Items
Drip edge, ice & water shield, underlayment, ridge cap, step flashing, and pipe boots are separate costs. A rough allowance is 10–20% on top of field shingles for accessories on a basic gable.
Step 4: Include Tear-Off, Disposal, and Permits
Single-layer shingle tear-off typically runs $1.00–$2.50/ft². Tile or layered tear-offs run $3–$5+/ft². Dumpster rental often adds $300–$600. Building permit fees range $50–$500 depending on jurisdiction.
Step 5: Apply Waste Before Finalizing Bundle Count
Add 5–8% waste for simple gables, 10–15% for cut-up hip or valley roofs, before converting ft² to bundle count. Always round up to whole bundles.
Roofing Quote Calculator Formulas
- Sloped roof area = Plan footprint ft² × Slope factor (e.g. 1.118 for 6/12 pitch)
- Field shingle material = (Sloped ft² × waste factor) ÷ Coverage per bundle × Price per bundle
- Project total = Field material + Accessories + Tear-off labor + Disposal + Permit fees
