How to Read a Roofing Estimate Line by Line
In this article
TL;DR: A roofing estimate is a contract waiting to happen. Know what each line covers, confirm nothing critical is missing, and compare bids on the same scope, not just the bottom number. A cheaper estimate that omits underlayment or permit fees is not a deal.
What You Need
- At least two written estimates (three is better)
- A printed or digital copy of each estimate in front of you
- The manufacturer spec sheet for any material being proposed
- Your county's permit fee schedule (Palm Beach County publishes this online)
- About 20 minutes per estimate
Step 1: Check the Contractor's License and Insurance Before Reading Anything Else
Before you read a single line item, find the contractor's license number on the estimate. In Florida, roofing contractors must hold a state-issued license. Look it up at the Florida Department of Business and Professional Regulation before you go further.
Also confirm: general liability insurance and workers' compensation. If a worker falls on your roof and the contractor has no workers' comp, that claim can come back to your homeowner's policy. Ask for a certificate of insurance, not just a verbal confirmation.
Any estimate that arrives without a license number printed on it should go straight in the recycle bin.
Step 2: Read the Scope of Work First, Not the Price
The scope section describes what the contractor is actually doing. This is where most homeowners skip ahead. Don't.
A complete scope for a residential reroof in South Florida should include:
- Remove existing roofing material (state how many layers)
- Inspect and document roof deck condition
- Replace damaged decking (note whether this is included or priced separately per sheet)
- Install new underlayment (specify type: peel-and-stick, 30-lb felt, synthetic)
- Install new field material (tile, metal, shingle, flat membrane)
- Replace or install all flashing, including pipe boots, valleys, and drip edge
- Haul away and dispose of all debris
- Final inspection and permit close-out
If any of these are missing, ask the contractor to explain in writing why. Sometimes a line is missing because it's genuinely not needed. Sometimes it's missing because they're planning to skip it.

Step 3: Break Down the Material Lines
Each major material should appear as its own line with quantity, unit, unit price, and total. Here is what to look for.
Roofing material (squares) Roofing is measured in squares. One square equals 100 square feet. Confirm the square count matches your roof size. A 2,000 sq ft house does not have a 20-square roof, because pitch and overhang add material. If the square count seems low, ask how it was calculated.
Underlayment This is one of the most important lines on the estimate and one of the most commonly watered down. Florida's building code requires specific underlayment depending on roof type. Peel-and-stick self-adhering membrane is the current standard for many applications under the Florida Building Code. If an estimate lists felt only, find out why. See Why Roof Underlayment Matters More in Florida for background.
Decking (roof sheathing) Some estimates include a set allowance (e.g., "up to 5 sheets included"). Others price it as a per-sheet add-on after tear-off. Neither approach is wrong, but you need to know which one applies. Roof deck damage is often discovered only after tear-off, so make sure the estimate explains how additional decking will be priced if needed. See Roof Deck Damage Missed Until Too Late for what that looks like.
Flashing and pipe boots These should be listed separately. Reusing old flashing on a new roof is a shortcut. Valley flashing, step flashing at walls, and pipe boot replacements should all appear on a full reroof estimate.
Drip edge Required by Florida Building Code on most roof types. If it is missing from the estimate, flag it.
Step 4: Verify the Labor Lines
Some estimates bundle labor and materials together per square. Others break them out. Either format is acceptable, but bundled pricing makes it harder to compare bids. Ask the contractor to separate them if you want an apples-to-apples comparison.
Look for:
- Tear-off and disposal (sometimes listed as demo)
- Installation labor per square
- Flashing labor (often separate from material cost)
- Clean-up and haul-away
If disposal is not listed, ask directly. In South Florida, dumpster rental and debris hauling are real costs. Contractors who don't list it are either absorbing it silently or planning to leave a mess.

Step 5: Find the Permit Line
In Florida, a roofing permit is required for a full replacement and most significant repairs. The permit fee is a real line item, and it should appear on the estimate. If it does not, ask the contractor who is pulling the permit and who is paying the fee.
A contractor who offers to skip the permit to save you money is not doing you a favor. An unpermitted roof replacement creates serious problems at resale and with your insurance carrier. Read more at Unpermitted Roof Replacement in Florida: What It Costs You.
The permit also means inspections, which is the county verifying the work was done correctly. That is not overhead. That is your protection.
Step 6: Check Warranty Terms
Two warranties apply to any roofing job: the manufacturer's warranty on materials, and the contractor's workmanship warranty.
Manufacturer warranty: Tile, metal, and shingle systems all carry manufacturer warranties, but the terms vary significantly. Some require specific installation methods or registered contractors to be valid. Ask for the warranty documentation, not just the sales pitch.
Workmanship warranty: This covers the contractor's labor. Length and terms vary. A contractor who won't put their workmanship warranty in writing is telling you something.
One thing to watch: some storm-chaser outfits show up after a hurricane, offer fast replacements, then leave the state. A workmanship warranty from a company that won't be here next year is worthless. Use a contractor with an established local presence.
Step 7: Compare Estimates on Equal Terms
Here is the most practical way to compare two or three bids side by side.
| Line Item | Estimate A | Estimate B | Estimate C |
|---|---|---|---|
| Square count | |||
| Underlayment type | |||
| Decking allowance | |||
| Flashing included? | |||
| Permit included? | |||
| Disposal included? | |||
| Workmanship warranty | |||
| Manufacturer warranty | |||
| Total price |
Fill this in with your actual bids. You will often find that the lowest number omits two or three items that add back up to the price difference.
Common Mistakes
Comparing bottom-line prices without matching scope. A $3,000 gap between two bids usually means one contractor is leaving something out, not that they are more efficient.
Accepting verbal promises. If a contractor says the permit is included but it is not on the estimate, get it added in writing before you sign.
Ignoring the payment schedule. A contractor who demands full payment upfront is a red flag. A reasonable schedule is a deposit to schedule, draw at material delivery or start, and final payment at completion and inspection close-out.
Not asking about change orders. Decking, rotted fascia, and hidden flashing damage can add cost after tear-off. Ask the contractor how change orders are handled and priced before work starts, not during.
Choosing a contractor only on price. The cheapest bid is fine if the scope matches and the license checks out. But if it is cheap because something is missing, you will pay for it later, usually as a roof repair within a few years.
Bottom Line
A roofing estimate is a document, not a brochure. Read the scope before you look at the price. Confirm the license, the permit, the underlayment type, the flashing plan, and the warranty terms. Then compare bids on the same scope.

Frequently asked questions
What does 'squares' mean on a roofing estimate?
A square is a unit of roofing material equal to 100 square feet of roof surface. Your square count will be higher than your home's footprint because it accounts for roof pitch and overhangs. If the square count on your estimate seems low, ask the contractor to show you how they measured.
Should I be worried if an estimate does not list a permit fee?
Yes. In Florida, a permit is required for most roof replacements. If the permit fee is missing, ask the contractor directly whether they are pulling a permit and who is covering the cost. Work done without a permit can create problems with your insurance carrier and at resale.
What is a reasonable payment schedule for a roofing job?
A typical schedule is a deposit to book the job, a draw when materials are delivered or work begins, and final payment after the job passes inspection. Any contractor asking for full payment upfront before work starts is worth approaching with caution.
How do I know if an estimate is leaving out important materials?
Compare the scope section against the list of items that should appear on a full South Florida reroof: underlayment type, decking allowance, flashing replacement, drip edge, permit, and debris disposal. If any of these are absent, ask the contractor to explain in writing before signing.
