Roofing Estimate Checklist: The 14 Line Items a Legitimate Minneapolis Bid Always Includes

The 14 line items. That’s the short version of this article, and it’s the single most useful filter you can apply to a Minneapolis roofing estimate. If a bid is missing any of them, the contractor is either (a) betting you won’t ask, or (b) planning to surface them later as a change order.

A good roofing estimate checklist turns three confusing quotes into a clear, side-by-side comparison — and it’s the document you’ll reference every time something comes up during the job. Here’s what the real one looks like, built from a decade of reading Twin Cities roofing contracts.

The roofing estimate checklist: what a complete Minneapolis bid looks like

Every one of these should be a named, quantified line item on the estimate. “Included” in fine print doesn’t count. If a contractor won’t specify a brand, a quantity, or a price, that’s the information you need.

1. Full tear-off or overlay specification — number of existing shingle layers removed.
2. Decking repair rate — per-sheet price for OSB or plywood replacement if rot is found. Typical 2026 rate: $60–$90/sheet installed.
3. Ice-and-water shield coverage — specify brand and how far up the roof (MN code minimum is 24″ past inside wall line; good contractors install more in valleys and around penetrations).
4. Underlayment brand and product line — synthetic vs. felt, specific product name.
5. Shingle brand, line, and color — “architectural” isn’t specific enough. “GAF Timberline HDZ, Charcoal” is.
6. Starter strip and hip-and-ridge caps — brand-matched to the main shingle for warranty eligibility.
7. Ventilation plan — intake and exhaust configuration, specific products (ridge vent, box vents, soffit baffles).
8. Flashing — how chimney, skylight, pipe boot, and wall flashings will be handled. “Re-use existing” is a cost-cut.
9. Drip edge — color, length, and whether it’s included (it should be).
10. Nails — galvanized or stainless; 6-nail pattern specified for wind coverage in MN.
11. Permit — pulled by the contractor, not the homeowner. Fee itemized.
12. Debris removal and magnetic nail sweep — included in base price.
13. Workmanship warranty — length and terms written out.
14. Manufacturer system warranty — product, tier (Silver/Gold/Platinum), and whether it’s included.

If your estimate has all 14, you have something you can actually compare. If it has 6, you have a deposit slip. See our guide to comparing bids for how to do that apples-to-apples.

What’s being hidden when a line item is missing from a roofing estimate checklist

Specific, high-leverage omissions you’ll see in bids that look cheaper than the competition:

This isn’t paranoia — it’s just pattern-matching on a few hundred Minneapolis roofing estimates. When the cheap bid is a real 3,000-foot overview with no detail, the savings almost always come out of items 3, 4, or 7 on the roofing estimate checklist above.

Beyond the line items: what else should be on a legitimate estimate

A complete Minneapolis roofing estimate also includes, outside the roofing estimate checklist itself:

• Contractor’s full legal name, MN license number, and physical address. See licensed contractors.
• Certificate of insurance information — a line confirming general liability and workers’ comp.
• Estimate validity period (usually 30 days for material pricing).
• Payment schedule — deposit, progress, and final payment milestones.
• Change order policy — in writing, signed before scope changes.
• Start and completion window (even an approximate weekly window is helpful).
• Cancellation clause — MN 3-day right of rescission acknowledged.

This is the paperwork that separates a real contractor from a sales operation. If any of it is missing, ask for it in writing before you sign. If the contractor resists, that’s a red flag worth listening to.

A roofing estimate that is vague in writing will be vague in practice. Every question left unanswered on paper becomes a disagreement on the jobsite — and the homeowner loses almost every one of those.

Homeowners who use a real roofing estimate checklist usually discover that the bids were never truly comparable — one contractor is proposing a full system with manufacturer backing, the other is proposing a labor-only reroof with the cheapest underlayment the distributor carries. Same square footage, radically different roofs. See the Minneapolis roofing companies pillar for how this fits into the larger hiring decision.

How to use this roofing estimate checklist with three competing bids

Practical workflow for a homeowner with three estimates in hand:

1. Print the 14-item checklist. Tape it to the fridge.
2. Go through each estimate line by line. Check off what’s included.
3. For every missing item, send an email asking for clarification in writing.
4. When all three replies are in, compare the filled-out checklists.
5. If one bid has significantly fewer items checked even after clarification, that bid isn’t actually the cheapest — it’s the smallest scope.

That process usually takes a weekend and saves roughly what you’d pay for a bad day of roof demo. For the next step in the decision process, see our roofing contract checklist and the questions to ask a roofing contractor. The GAF homeowner education center also publishes a homeowner guide with similar line-item expectations if you want a second perspective.

Frequently Asked Questions

What should a roofing estimate checklist look like for a Minneapolis home?

A legitimate estimate includes 14 named line items covering tear-off scope, decking repair rate, ice-and-water coverage, underlayment, shingle brand and line, starter and ridge caps, ventilation, flashing, drip edge, nails, permit, cleanup, workmanship warranty, and manufacturer system warranty. Anything less is incomplete.

How much detail is reasonable to ask for on a roofing estimate?

As much as you need to compare it to another bid line by line. Brand and product line for shingles, underlayment, and ice-and-water shield are standard. A contractor who won’t provide that detail is planning to flex after signing.

Should the estimate include a specific start date?

A start window is reasonable (e.g., “last week of June, weather dependent”). A specific hard start date is not always possible during storm season, but the window and the completion timeline should be written.

What’s the typical decking replacement rate in a Minneapolis estimate?

In 2026, roughly $60–$90 per sheet of OSB or plywood installed, including disposal of the rotten panel. Bids often state this as a conditional rate — the contractor only charges if rot is found during tear-off.

Should the estimate be signed before work starts?

Yes — once your roofing estimate is converted into a written, signed contract. The estimate itself is typically a proposal; the contract is what binds both parties. See our roofing contract checklist for the next step.
