How to Read a Roofing Estimate: What Every Line Item Means

You asked three roofing contractors to give you quotes. They came back with very different numbers and different-looking documents. One is a single page. Another is four pages. One contractor said their price is lower because they skip the permit. Another charges extra for "mobilization." How are you supposed to compare these?

This guide breaks down every common line item in a Florida roofing estimate so you know exactly what you are comparing and what questions to ask before you sign anything.

Section 1: Scope of Work

The scope of work should be the first thing you read on any estimate. It describes precisely what the contractor will do: full tear-off, install secondary water barrier, replace decking as needed, install new shingles, replace flashing, install new pipe boots, and so on. A good scope of work is specific. If the scope simply says "install new roof," that is a red flag. You need to know exactly what is included before comparing prices.

Important items to look for in the scope of work include whether tear-off is included (it should be for a full replacement), whether the secondary water barrier is specified (required by Florida law in Broward County), and whether old material disposal is included.

Section 2: Roofing Materials

Material line items tell you what brand, product line, and quantity will be used. Pay attention to these details because two estimates may both say "architectural shingles" but use products with very different warranties and quality levels.

Squares

Roofing is measured in "squares," where one square equals 100 square feet of roof surface. A 2,000 square foot home does not have a 20-square roof because the roof has pitch, overhang, and multiple planes. The actual square count for that home might be 24 to 28 squares depending on roof complexity. If two contractors give you very different square counts for the same home, ask them both to explain their measurement.

Shingles

The estimate should name the specific shingle product: for example, GAF Timberline HDZ or Owens Corning Duration. Look for the class rating (Class 4 impact-resistant shingles are better for Florida), the wind warranty (150 mph is good, some products go higher), and the manufacturer warranty term. A 50-year limited warranty from the manufacturer is standard for premium architectural shingles. Note that warranty terms vary based on whether the contractor is a certified installer for that manufacturer.

Underlayment

Florida requires a secondary water barrier on all residential reroofing in High-Velocity Hurricane Zones, which includes all of Broward County. This is typically a self-adhering modified bitumen product applied directly to the decking. The estimate should specify the product. If the estimate does not mention underlayment or secondary water barrier at all, ask the contractor to clarify.

Drip Edge

Drip edge is metal flashing installed at the eaves and rakes of the roof. It directs water away from the fascia and into the gutters. It is required by Florida Building Code on all new and replacement roofs. If it is not on the estimate, ask why.

Ridge Cap

Ridge cap is the shingle product applied along the peak of the roof. Some estimates include a hip-and-ridge shingle product that is designed specifically for high-wind performance. Others use cut-up field shingles as ridge cap, which is cheaper but provides less protection at one of the most wind-exposed points on the roof.

Pipe Boots and Flashing

Every penetration through the roof (plumbing vents, HVAC lines, exhaust fans) needs a sealed boot or flashing. Pipe boots deteriorate over time and are a common source of leaks. A full replacement estimate should include replacement of all existing boots and flashing. If the estimate says "reuse existing flashing," push back on that, particularly for an older roof where flashings are corroded or deteriorated.

Section 3: Labor

Labor covers the cost of the installation crew. Some estimates break this out separately; others bundle it with materials. What matters is that the total reflects honest pricing. Extremely low labor costs on an estimate can indicate unlicensed workers, no workers compensation coverage, or a contractor cutting corners on the installation process.

Section 4: Decking and Wood Replacement

No contractor can tell you exactly how many decking sheets need to be replaced before the old roof is torn off. Rotted or soft decking is only visible once the existing material is removed. Legitimate estimates handle this in one of two ways: a fixed per-sheet price for any decking that needs replacement (typically listed as a line item at a per-sheet rate), or an allowance of a set number of sheets included in the base price.

Be cautious of an estimate that claims zero decking replacement will be needed on an older roof. That is almost never the case in Florida, where humidity and storm exposure accelerate wood deterioration. Get a per-sheet rate in writing before work starts so you are not surprised by the final invoice.

Section 5: Permit and Inspection Fees

In Broward County, a permit is required for every full roof replacement. The permit fee is set by the municipality and is typically between $150 and $500 depending on the jurisdiction and project value. The estimate should include a line item for permit fees. If it does not, and you were not told permits are excluded, ask the contractor directly: are you pulling a permit for this job?

Never hire a contractor who suggests skipping the permit to save money. Without a permit, the work cannot be inspected, it may not be covered by your homeowners insurance, and it can create serious problems when you sell the home. The county also issues fines for unpermitted roofing work.

Section 6: Disposal and Clean-Up

Tear-off produces a significant amount of debris. The estimate should include disposal costs, which cover the dumpster or trailer rental and the cost of dropping the material at a licensed disposal facility. Some contractors charge this as a flat fee; others calculate it per square. Make sure this is in the estimate so you do not get charged extra after the fact.

Section 7: Warranties

A roofing estimate should reference two separate warranties. The first is the manufacturer warranty, which covers defects in the roofing material itself. The second is the contractor workmanship warranty, which covers installation errors. These are entirely separate. A manufacturer warranty does nothing for you if the leak was caused by improper flashing installation rather than a defective shingle.

Ask the contractor what their workmanship warranty covers and how long it lasts. Standard in Florida is one to five years on workmanship; some contractors offer longer. Get this in writing in the contract, not just the estimate.

Things to Watch For When Comparing Estimates

• No permit mentioned: Walk away if a contractor does not pull permits.
• No secondary water barrier: Required by Florida law. If it is not in the estimate, they are not including it.
• No workmanship warranty: If they will not put it in writing, it does not exist.
• Unlicensed contractor: Verify the license number at myfloridalicense.com before signing. An unlicensed contractor cannot legally pull permits.
• Significant price differences: If one estimate is 30 percent lower than the others, the difference is usually in what is not included. Compare scopes line by line before assuming the low bid is a good deal.
• Pressure to sign the same day: Reputable contractors give you time to review and compare. A contractor who uses high-pressure tactics to get a same-day signature is often trying to prevent you from reading the fine print.

Questions to Ask Every Contractor Before Signing

• Are you pulling the permit, and is it included in this estimate?
• What is your workmanship warranty, and can you put it in the contract?
• Are your workers employees or subcontractors, and are they covered by workers compensation?
• What is the per-sheet price for any decking replacement found during tear-off?
• Is disposal included, and how do you handle the final clean-up?
• What is the estimated timeline from permit approval to project completion?
