What’s Included in a Roof Replacement Estimate? | Bigfoot Windows & Roofing
Last updated: July 2026 by the Bigfoot Windows & Roofing editorial team.
Key Takeaways
- A complete South Florida estimate should itemize materials, labor, permit fees, disposal, and code-required underlayment — never a single lump sum.
- HVHZ (Miami-Dade and Broward) rules add NOA-compliant products, third-party inspections, and stricter underlayment requirements that raise material costs.
- Permit fees in Miami-Dade vary by project size; they must appear as a separate line item, not buried in overhead.
- If you have an insurance claim, your contractor’s scope should align line-for-line with the Xactimate report your adjuster produced.
- A vague lump-sum quote is a red flag — ask for a written scope of work before signing anything.
The Problem
Why South Florida Roof Estimates Look So Different From What You Find Online
National cost calculators don’t account for HVHZ code, NOA requirements, or Miami-Dade permit processes — so the number on your estimate can feel like a shock.
You searched “roof replacement cost” and found national averages of $8,000–$15,000. Then your South Florida contractor hands you an estimate for $18,000–$28,000 and you wonder what went wrong. Nothing went wrong. Florida’s High-Velocity Hurricane Zone (HVHZ) — which covers all of Miami-Dade and Broward County — imposes code requirements that simply don’t exist in most of the country. Those requirements cost money, and every one of them should appear as a named line item on your estimate.
This article walks through every cost category you should expect to see, explains why each one exists, and tells you what’s missing from an estimate that probably isn’t worth signing.
Local Context
How HVHZ and Florida Building Code Shape Every Line Item
Miami-Dade and Broward counties sit inside the High-Velocity Hurricane Zone, the most demanding building-code environment in the United States for residential roofing. Florida Building Code Section 1504 governs roof coverings in the HVHZ and requires that every material installed carry a valid Miami-Dade Notice of Acceptance (NOA) or Florida Product Approval number. That approval isn’t a marketing claim — it’s a testable document your inspector will verify before issuing a final permit sign-off.
What this means for your estimate: your contractor cannot substitute a cheaper shingle or underlayment that lacks NOA compliance, even if it’s widely sold at local supply houses. If the product isn’t on the Miami-Dade approved list, it doesn’t go on the roof. Period. Estimates that use non-approved materials to lower the price are setting you up for a failed inspection and a costly redo.
Palm Beach County sits just outside the strictest HVHZ zone but still operates under Florida Building Code wind-speed maps that require high-wind fastening schedules, specific underlayment types, and permit pulls. The cost difference between Palm Beach and Miami-Dade is real but smaller than most homeowners expect.
Line-Item Breakdown
Every Cost Category a Roof Replacement Estimate Should Include
If one of these is missing, ask before you sign.
| Line Item | Why It’s on the Estimate | HVHZ Impact |
|---|---|---|
| Tear-off and disposal | Removing old roofing, decking debris, and nails; includes dumpster or haul-away | Double-layer roofing common in older Miami-Dade homes adds labor cost |
| Underlayment | The water barrier between deck and roof covering | HVHZ requires minimum two-layer 30-lb felt or ASTM D226 Type II — one layer fails inspection |
| Roof covering (shingles, metal, tile) | The visible roof surface and primary weather barrier | Must carry Miami-Dade NOA or Florida Product Approval number |
| Decking repair / replacement | Rotted or damaged OSB/plywood replaced before new roofing | Inspector will probe deck; hidden rot discovered mid-job is a legitimate change order |
| Drip edge & flashing | Metal trim at eaves and rakes; step and counter flashing at walls and chimneys | FBC requires drip edge; improper flashing is a leading cause of failed re-inspection |
| Permit fee | Required by every Florida municipality for roof replacement — no exceptions | Miami-Dade permit fees scale with project value; typically $350–$900 for residential |
| Third-party inspection | Miami-Dade requires a DBPR-licensed inspector to sign off on HVHZ work | Adds $150–$400 depending on project complexity; must appear on estimate |
| Ice-and-water shield / peel-and-stick | Self-adhering underlayment at eaves and in valleys | 2024 FBC update allows direct-to-deck peel-and-stick; full-deck application qualifies for Citizens Insurance secondary water barrier discount |
| Ridge cap / ridge vent | Caps the peak of the roof; ventilation affects attic heat load and shingle life | Must be same-system NOA as field shingle — not generic ridge cap |
| Labor | Installation crew, foreman oversight, site cleanup | HVHZ nailing schedules are stricter and slower — higher labor rate than national average |
A note on decking: contractors cannot know exactly how many sheets of decking need replacement until tear-off is complete. A reputable estimate should state the per-sheet replacement rate (typically $80–$130 per 4×8 sheet installed in South Florida) rather than guessing a lump-sum number. That way you’re not overcharged on a good deck or surprised by a massive bill on a rotted one.
Estimate Comparison
Itemized Scope vs. Lump-Sum Quote: What the Difference Tells You
| Feature | Vague Lump-Sum Quote | Itemized Written Scope |
|---|---|---|
| Permit cost | Buried or omitted | Named line item with municipal fee |
| Underlayment spec | “Standard underlayment” | ASTM D226 Type II, layer count, NOA number |
| Decking replacement | “Included” — no rate | Per-sheet rate stated; T&M on discovered rot |
| Disposal | May be extra at completion | Fixed-price line item upfront |
| Insurance alignment | Cannot match Xactimate line items | Matches adjuster scope line for line |
| Change order risk | High — undefined scope = undefined cost | Lower — known scope, change orders for genuinely unknown conditions only |
When a lump-sum quote might be acceptable: very small repairs (less than 10% of roof area) where scope is already visually confirmed. For a full replacement, always insist on an itemized written scope.
Why Scope Matters
One Contractor, Four Licenses — Structural Issues Handled In-House
A licensed contractor, not a lead aggregator.
Because Bigfoot holds a Certified General Contractor license (CGC1531370) in addition to its Certified Roofing Contractor license (CCC1333168), structural modifications that surface during a roof replacement — hurricane strap installation, rafter sister repairs, or load-path corrections — can be handled under the same contract. Many roofing-only contractors must sub out or walk away from structural work, creating a gap in accountability and a second permit pull. When structural scope is discovered mid-project, having a single contractor authorized to handle it simplifies the scope, the permit record, and the communication chain.
“A good estimate isn’t just a price — it’s a written promise about what you’re getting. If the scope isn’t specific, the price doesn’t mean anything.”

Roofing Systems
NOA-Compliant Products That Should Appear on Your Estimate
Every product named on your estimate should carry either a Miami-Dade NOA number or a Florida Product Approval number for the HVHZ. When we write estimates for South Florida roofing projects, we specify the approval number alongside each material so inspectors and homeowners can verify compliance independently.
GAF shingle systems: GAF TimberlineHDZ shingles carry Miami-Dade NOA approval. As a GAF Silver Plus certified contractor, we can offer the System Plus warranty — 50 years non-prorated, covering shingles, labor, tear-off, and accessories. Wind Proven unlimited-mph coverage applies when the full GAF system is installed. A 2024 Florida Building Code update now permits direct-to-deck peel-and-stick underlayment; full-deck application qualifies for a Citizens Insurance secondary water barrier discount — a line item worth requesting separately on your estimate.
Englert standing seam metal: Panels are fabricated and roll-formed on-site in one continuous piece from bottom to top — no horizontal seams that can fail in a hurricane. The Englert clip system uses Englert-stamped clips at specific spacing intervals required for NOA compliance; substituting knockoff clips is a known cause of failed inspections and full roof redos. Standing seam metal carries a 50-year warranty.
Westlake tile: Concrete and clay tile must be set with poly-set foam (rated to 180 mph) or mechanical fasteners (rated to 160 mph). Whichever method your estimate specifies, the NOA number for that setting method should be listed. For homeowners exploring financing options for tile roofs, PACE financing is structured separately from standard loan products and is paid through the property tax bill.
The Process
How the Estimate Becomes a Permitted, Inspected Roof
- On-site assessment: We inspect the deck, measure the roof, identify flashings, and document any visible structural or drainage issues before writing a single number.
- Written scope of work: Every line item detailed — materials with approval numbers, labor, permit fee, disposal, and a per-sheet decking rate for discovered rot.
- Permit application: We pull the permit before work begins. In Miami-Dade, this includes submitting NOA documentation to the building department. Permit costs appear on your estimate, not as a surprise at closing.
- Installation: Work proceeds per the permitted scope. If hidden rot or structural issues surface, we document and price the change order before proceeding — you approve it before we continue.
- Third-party inspection: For HVHZ projects, a licensed inspector verifies code compliance at key stages. That inspection fee is on your estimate from day one.
- Final sign-off: Permit is closed, you receive documentation, and warranty paperwork is processed.
If you have an active insurance claim, request the Xactimate report from your adjuster and share it with us. Our written scope maps line-for-line to the adjuster’s itemization so there are no gaps between what insurance approved and what we’re contracted to install.

Who We’re Not the Right Fit For
- Budget-first buyers who need the absolute lowest number: Our estimates are itemized and code-complete. If a non-permitted or non-NOA-compliant job would satisfy you, we’re not the right contractor — and we’d encourage you to verify any contractor’s permit record with the county before signing.
- Projects requiring electrical, plumbing, or HVAC coordination as the primary scope: We hold roofing, residential, general contracting, and glass & glazing licenses. We do not hold electrical, plumbing, or mechanical licenses. If your re-roof is tied primarily to a solar or HVAC project, you’ll need a licensed trade contractor for those scopes.
- Homeowners who prefer a handshake-and-a-price arrangement: We require a written scope of work before any project begins. If a verbal agreement is your preference, we’re not a match.
- Commercial high-rise or large-scale commercial roofing: Our core work is residential and small commercial in Miami-Dade, Broward, and Palm Beach. Large commercial TPO or built-up roofing on multi-story structures is outside our current scope.
Frequently Asked Questions
What should a roof replacement estimate include in Florida?
A complete Florida roof replacement estimate should include: tear-off and disposal, underlayment (with ASTM spec and NOA number), roof covering (shingles, metal, or tile with product approval), drip edge and flashing, decking repair rate per sheet, permit fee, third-party inspection fee (HVHZ), and labor. Each item should be a named line — never a single lump sum. Missing any of these is a sign the scope may be incomplete or that costs will surface later as surprise change orders.
How much does a roofing permit cost in Miami-Dade and is it included in my estimate?
Miami-Dade permit fees for residential roof replacement typically range from $350 to $900 depending on project value and roof area. A reputable contractor includes this as a named line item on the estimate — not buried in overhead or added at the end. Never sign an estimate that omits the permit fee; it signals either the contractor planned to skip the permit or plans to bill it separately at completion.
Why is my South Florida roof estimate higher than estimates I see online?
National cost calculators are based on average U.S. conditions. South Florida’s HVHZ requires NOA-compliant materials, two-layer underlayment, stricter nailing schedules, permitted work with third-party inspections, and licensed contractors. Each requirement adds real cost. An estimate that matches a national average for a Miami-Dade home is almost certainly missing one or more required line items — which means you’ll pay for them later, possibly after a failed inspection.
What is an NOA and does my roofer need one for my Miami-Dade home?
An NOA (Notice of Acceptance) is a Miami-Dade County product approval document that certifies a roofing material has been tested and accepted for use in the HVHZ. Any roofing product installed in Miami-Dade or Broward must carry a valid NOA or a statewide Florida Product Approval number. Your contractor should list the NOA or approval number next to each material on the estimate. If they can’t provide it, that material may not pass inspection.
Should labor, materials, permits, and disposal all be separate line items on a roofing estimate?
Yes. Each category should be a distinct line item so you can verify what you’re paying for. A combined lump sum makes it impossible to compare contractor bids accurately, align with an insurance adjuster’s Xactimate report, or identify what was excluded. When reviewing an estimate, if you can’t tell how much is materials versus labor versus permits, ask the contractor to break it out. A contractor confident in their pricing will do so without hesitation.
How do I make sure my contractor’s estimate matches my insurance claim?
Request the Xactimate report from your insurance adjuster and share it with your contractor before they write the estimate. A detailed contractor scope should map line-for-line to the adjuster’s itemization. If the contractor’s scope omits items the adjuster approved — or adds items the adjuster didn’t include — get a written explanation before signing. Gaps between the insurance scope and the contractor scope often become disputes at payment time.
Can I finance a roof replacement in South Florida and how does that affect my estimate?
Yes. PACE financing is one common option — it’s paid through your property tax bill, not a traditional bank loan, at a rate of approximately 9.49%. A 20-year term minimizes monthly payments. Roofing and window replacements must be submitted as separate PACE applications. The My Safe Florida Home grant offers up to $10,000 for qualifying improvements and can be stacked with PACE. For tax implications of any financing method, consult your CPA.
