What roofing contractors need in estimate software

A basic spreadsheet won't cut it for roofing. You need software that handles:

• Material takeoffs — shingles by square (100 sqft), underlayment, ice & water shield, ridge cap, pipe boots
• Waste factor — typically 10–15% on a simple gable, 20–25% on complex hip/valley roofs
• Labor tiers — tear-off & haul, install, flashing, ridge vent
• Permit fees — vary by county, often $150–$500
• Markup & margin — most roofing contractors aim for 35–45% gross margin

How to estimate a roofing job step by step

1. Measure the roof area — use satellite (EagleView/Hover) or walk the roof. Convert to squares.
2. Calculate materials — (roof area × waste factor) ÷ coverage per unit
3. Add penetrations — each chimney, skylight, and pipe boot adds cost and labor time
4. Estimate tear-off — 1 layer = ~1.5 hrs/square; 2 layers = ~2.5 hrs/square
5. Apply overhead + profit — materials cost × your multiplier

Roofing pricing quick reference (2026)

• 3-tab asphalt shingle — $3.50–$5.50/sqft installed
• Architectural shingle — $5–$8/sqft installed
• Metal roofing (standing seam) — $12–$22/sqft installed
• Tile roofing — $15–$30/sqft installed
• Flat roof (TPO/EPDM) — $6–$12/sqft installed
• Tear-off & haul — $1–$2/sqft per layer

Common estimating mistakes roofers make

• Forgetting the waste factor on complex roofs — always add ≥15%
• Underestimating decking repairs until tear-off reveals rotted sheathing
• Not itemizing flashing separately — leads to disputes at invoice time
• Sending a single-number bid with no breakdown — clients shop on price alone
