What Is Included in a Roof Replacement Quote? (Line by Line)

A complete roof replacement quote spells out the full tear-off, a written per-sheet price for decking replacement, ice and water shield coverage in feet, the underlayment type, the exact shingle brand and line, the ventilation plan, every flashing and accessory, permit and disposal costs, and both warranties, split into labor and material so you can see what you are actually paying for. If a quote skips any of those, you are not comparing apples to apples with one that includes them.

I am Aaron Scott, licensed Michigan residential builder and owner of Roofing Army. On our calls this year, 45 homeowners ask us what is actually included in a quote, and another 17 ask specifically whether decking boards cost extra. Both are the right questions. A one-page quote with a single number tells you nothing about what happens if the crew finds rotted plywood, whether your attic is getting real ventilation, or whether the flashing around your chimney is being rebuilt or just resealed. Here is every line item that should be on a real quote, in the order it usually appears, with real numbers from the roofs we quote in Southeast Michigan.

What Line Items Belong on a Roof Replacement Quote?

A quote you can actually compare against another one lists these items individually, not folded into one lump sum:

• Tear-off and disposal. How many existing layers the price assumes, and what happens (in writing) if the crew finds more once the first layer comes off.
• Decking replacement, priced per sheet. A dollar figure for each sheet of new OSB or plywood, agreed before the crew ever gets on the roof.
• Ice and water shield, stated in feet. Coverage at the eaves plus valleys, chimneys, skylights, and any wall transitions, not just "code minimum."
• Underlayment type and fastener. Synthetic underlayment, not felt paper, fastened with plastic cap nails rather than staples.
• Exact shingle brand, line, and color. "Architectural shingles" is not a specification. The brand and product line should be named.
• Ventilation plan. What intake and exhaust exist now, and exactly what the new roof will add or change.
• Flashing and accessories, itemized. Chimney flashing, wall flashing, valley metal, pipe boots, drip edge, ridge cap, starter strip.
• Permit and dumpster. Who pulls the permit and under whose license, plus the dumpster and cleanup cost, rolled into the number, not billed separately later.
• Both warranties, with actual years. The manufacturer's material warranty and the contractor's workmanship warranty, each with a real term in writing.
• Payment terms. When payment is due, and whether a deposit is required before materials are delivered.

For a full walkthrough of how each of those factors moves the actual dollar amount, see our roof replacement cost guide. This post is about the shape of the quote itself, the line items a fair one contains and what each one is protecting you from.

What Is a "Wood Allowance," and Why Does It Cause Change Orders?

Nobody, including us, knows exactly what the decking looks like until the old shingles are off. That is why a real quote does not guess at decking cost. It sets a wood allowance instead: a fixed price per sheet of OSB or plywood, agreed to before the crew starts, that only gets charged if that sheet is actually needed. On the replacement quotes we write, 38% end up needing some decking replaced, at a median of 48 sheets when it happens, with the middle half of those jobs replacing between 24 and 80 sheets. That is a wide range, which is exactly why the per-sheet price has to be in writing up front rather than negotiated on your driveway after the tear-off has already started.

This is also where the term "change order" comes from. A change order is a written addition to the contract, priced at the rate you already agreed to, for work the original quote could not have predicted, like extra decking or a rotted rafter tail. A legitimate change order references the wood allowance you signed. A red flag is a crew that tells you the price "just went up" without a per-sheet number to point back to.

How Often Does Each Line Item Actually Show Up on a Real Quote?

These are not hypotheticals. This is what we actually find across the replacement quotes we write in Southeast Michigan, and it explains why a fair quote has to account for every one of these possibilities rather than assuming a clean, simple roof:

A quote that never mentions pipe boots, for example, is unusual, since we replace at least one on 87% of the roofs we tear off. Chimney flashing work shows up on more than half of our jobs. If your home has a chimney and the quote does not address flashing at all, ask why. These items are also invisible from the street, which is exactly why a phone quote or a driveway walk-around cannot price a roof the way a full on-site inspection can; we cover that separately in why a roofer will not give you a price over the phone.

How Should a Quote Split Labor and Material?

A quote that breaks the price into labor and material tells you more than one that shows a single total, because it shows you what you are paying for the work versus what you are paying for the shingles, flashing, and decking themselves. Across the replacement options we price this year, the median material share is $6,238, with the middle half between $4,543 and $8,358, and the median labor share is $4,298, with the middle half between $3,085 and $6,012. Material typically runs somewhat higher than labor on a standard asphalt roof, which makes sense since it includes the shingles, underlayment, ice and water shield, flashing, and all the fasteners, but a roof with unusually steep pitch, multiple stories, or extensive decking replacement can push the labor share higher relative to material. If a quote will not break out labor from material at all, you cannot tell whether a "discount" is coming out of the crew's time, the materials being used, or both.

What Should the Permit and Warranty Lines Actually Say?

Two line items get glossed over more than any other on a cheap quote: the permit and the warranty.

The permit line should name who is pulling it, under whose license, and whether the fee is already included in your total. Permit fees vary widely by city and township across Southeast Michigan, from flat fees under $150 in some jurisdictions to valuation-based fees well over $500 in others; our roof permit guide breaks down what homeowners actually pay across our service area so you can check the number against your own city.

The warranty line needs two separate terms, not one. The manufacturer's material warranty covers defects in the shingle itself, and the contractor's workmanship warranty covers whether the crew installed it correctly, which is a completely different thing and a completely different company standing behind it. Our own callers arrive at estimates confused by other roofers' "lifetime" language on this point more than almost any other topic, roughly 75 calls a year mention warranty, and 18 of those specifically ask us to separate labor from manufacturer coverage. Ask for both terms in years, in writing, before you sign anything. Our own guide to questions worth asking before you sign covers warranty language and eight other questions that matter just as much as the price.

Why Do Two Quotes for the Same Roof Look So Different?

The single biggest reason two quotes for the same roof come back far apart is not that one company is padding its price. It is that one quote priced every item on the list above and the other one skipped several of them. A quote missing a written wood allowance is betting you will not push back on a change order later. A quote with no stated ice and water shield footage may be installing the bare code minimum instead of full eave and valley coverage. A quote with one lump-sum number and no labor or material split gives you nothing to compare against the next bid. None of that shows up as a difference in quality until the crew is already on your roof.

We build every homeowner five quotes at different price points on the same measured roof, specifically so you can see these line items change side by side rather than comparing a single number from us against a single number from someone else. It is also why we publish the real price of every project we complete, with the address and square footage, in our job gallery, so you have a real anchor for what a complete quote actually costs before anyone sits down at your kitchen table.

Get a Line-by-Line Quote for Your Roof

A free on-site inspection is how every one of the line items above gets priced accurately instead of estimated: the actual pitch, whatever the decking looks like once we can see it, the chimney and vent flashing, and the ventilation your attic actually has. You will get a written quote the same day, broken into labor and material, usually with five options at different price points, and nothing added later that was not already accounted for. We serve Southeast Michigan from offices in Oxford, Ferndale, and Rochester Hills. Learn more about how we build a roof on our roof replacement page, check current plans on our financing page if you would rather pay monthly than all at once, and schedule the inspection that turns this list into your actual number.
