Estimate comparison guide

This is a simple homeowner worksheet you can download and use while you compare roofing estimates. It is made to help you review bids for metal roofing and asphalt roofing in a clear, organized way.

The guide does not tell you which contractor to hire. It does not replace your local code office, your insurer, or a licensed roofer. It helps you ask better questions and keep the important details in one place.

If you are still learning the basics, start with metal vs asphalt or see typical roofing costs.

A roofing estimate is not just one price. You want the scope, materials, protections, and warranty terms in writing before any deposit.

Use the guide to compare:

• Roof type: asphalt, corrugated/ribbed metal, metal shingles, or standing seam
• Material details: metal type, panel or shingle style, gauge, and coating or finish
• Tear-off and disposal: full tear-off, overlay, dumpster, cleanup, haul-away
• Deck and trim items: underlayment, flashing, valleys, drip edge, ridge caps, pipe boots, vents
• Labor and jobsite protection: landscaping protection, magnet sweep, daily cleanup
• Permits and code items: who pulls permits, who handles inspections, what code upgrades are included
• Warranty language: manufacturer warranty, workmanship warranty, and what can void them
• Payment schedule: deposit amount, progress payments if any, and final payment terms

A lower number is not always the better deal. One estimate may include items that another leaves out. That is why side-by-side comparison matters.

For metal roofs, ask for the metal type, gauge, coating, warranty, scope, and total price in writing. Always hire licensed, insured, bonded roofers and verify the license and insurance yourself.

1. Download the PDF and save it where you can edit or print it: roofing-estimate-comparison-guide.pdf.
2. Collect at least 2-3 estimates for the same job. If possible, ask each roofer to price the same scope so the comparison is fair.
3. Fill in each line item exactly as written on the estimate. Do not rely on verbal promises.
4. Circle missing details. If one roofer does not list gauge, coating, underlayment, flashing, permits, or cleanup, ask them to revise the estimate.
5. Compare total value, not just price. A metal roof usually costs more up front than asphalt, but metal typically lasts about 40-70 years while asphalt often lasts about 15-25 years. Still, asphalt can be the smarter call if you have a tight budget or do not plan to stay in the home long.

Typical installed price ranges are often around $5-$9/sq ft for corrugated/ribbed metal, $9-$14/sq ft for metal shingle, $10-$18/sq ft for standing seam, and $4-$8/sq ft for asphalt. These are estimates, not quotes. Real price depends on roof size, pitch, the metal and coating chosen, tear-off, and your area.

When you compare estimates on paper, problems become easier to spot.

• Very low price with vague scope
• No mention of permits or inspections
• No metal gauge or coating listed
• No details on flashing, valleys, or penetrations
• Large deposit with little in writing
• Warranty promises that sound broad but say very little
• No proof of license, insurance, or bond

If a roofer says, "Don't worry, we'll handle everything," slow down and ask for specifics in writing. You should know what is included before money changes hands.
