How do I compare contractor quotes?

Compare contractor quotes line-by-line on scope, materials, timeline, payment schedule, and warranty — not just bottom-line price.

Step 1: Standardize the scope

Send all contractors the exact same written scope of work. If they re-bid different scopes, you can't compare fairly.

Step 2: Check materials and brands

A 'new roof' could mean basic 3-tab shingles or premium architectural shingles — a 2x cost difference. Demand specific brand and grade.

Step 3: Compare timelines and crew size

A 2-week project with a 4-person crew is very different from a 6-week project with one part-timer. Factor in your time and disruption.

Step 4: Watch the payment schedule

Reputable contractors collect 10–25% upfront, milestone payments tied to completed work, and final payment after walk-through. Anyone asking for 50%+ upfront is a red flag.

Step 5: Compare warranties

Ask about labor warranty (1–10 years) and material warranty (varies by manufacturer). Get warranty terms in writing.

Frequently asked questions

Is the lowest quote always bad?

Not always, but it's often a sign of inexperience or planned change orders. Mid-range quotes from reviewed pros usually offer the best value.

How many quotes should I get?

At least 3, ideally 4–5 for major projects ($10k+).
