Compare scope and cost side by side.

Storm / insurance review

Use when contractor and adjuster scope do not match.

Step 1: Compare scope, not just total

Put quotes side by side and check if every one includes the same core work: permit, inspection support, full teardown, underlayment, flashing, drip edge, ventilation, and cleanup.

Step 2: Normalize to price-per-square

If your roof area differs, compare price per square foot or per square. This reveals whether a lower total is due to smaller work or hidden cuts.

Step 3: Identify every missing line item

If one estimate leaves out a common item, ask for a written update. Clean scope is usually worth more than a small discount on paper.

Step 4: Ask questions, then trust your schedule

Ask one question per gap. Good contractors answer directly and clearly. Good clients compare calmly and pick based on both price and confidence.

FAQs

Should I compare total price or square footage first?

Start with scope first, then compare total and price-per-square. A lower total with lighter scope is not always better.

Is one quote being much cheaper a red flag?

Not automatically. Check for missing line items like permit, underlayment, or flashing before assuming the price is unrealistically low.

Can I compare estimates if contractors use different line names?

Yes, by translating terms into jobs. Ask for a plain scope summary and line it up with the others in the same categories.

I am not technical. Can I still use this?

Yes. You can upload one PDF or photo first, then add another file only if you want a cleaner comparison.
