What happens if you skip the permit (and you needed one)
- Stop-work order issued by the Building Department carries a $500–$1,500 fine in Sebastian, plus mandatory re-permitting at double the original fee once work is halted.
- Insurance claim denial: insurers require proof of permit for roof damage claims; unpermitted reroof work can void coverage, leaving you uninsured for future wind or weather events.
- Title and resale problem: unpermitted roof work must be disclosed on the Seller's Disclosure form in Florida; buyers and lenders will demand proof of permit compliance before closing, potentially forcing costly retroactive inspections or removal.
- Lender refinance block: if you refinance after an unpermitted roof, the lender's title search and property inspection will flag the missing permit, halting the loan until the work is brought into compliance or removed entirely.
Sebastian roof replacement permits — the key details
Sebastian's Building Department applies Florida Building Code Section 7 (or 8, depending on adoption cycle) to all roof work. The critical rule is FBC 7-3-1202 (secondary water barrier): any reroof in Sebastian — even a like-for-like asphalt-shingle replacement — requires a continuous secondary water barrier (ice-and-water shield or equivalent) installed from the lowest roof eave to at least 2 feet up the roof slope (or 24 inches beyond the interior wall line, whichever is greater). This is MORE stringent than the baseline IRC R905.1.1 requirement because of Sebastian's high-wind-zone status. Your roofing contractor must specify the SWB product by name in the permit application and show its installation footprint on a sketch or photo. If they submit the application without this specification, the city's plan reviewer will return it incomplete. IRC R907 (reroofing) mandates that if the existing roof has THREE layers, a complete tear-off is required before new material can be installed — overlay is prohibited. Sebastian's inspectors actively probe existing roofs during pre-tear-off inspections to count layers; if a third layer is found after permitting began, you'll face a re-inspection and potential compliance hold. The cost impact is significant: a tear-off of three layers can add $1.50–$3.00 per square foot to labor and disposal, versus an overlay (which saves the old material).
Sebastian's permit process includes an intake step unique to coastal Florida: the applicant (or contractor) must declare the roof's exposure category — either 'Open Country' (isolated trees, flat terrain), 'Suburban' (low-rise development, trees), or 'Urban' (downtown, tall buildings). This classification determines your Design Wind Speed (DWS), which Sebastian uses to set fastening patterns and product specifications. For example, a Suburban-exposure roof in Sebastian has a DWS of roughly 130–140 mph (Category 3 hurricane equivalent); Urban exposure is lower. If you mis-classify and the city's reviewer catches it, the application bounces back for re-submission, adding 5–7 days. Once classified, your fastening pattern — number and placement of nails or screws per shingle — is non-negotiable. Asphalt shingles in Suburban exposure require 6 nails per shingle in the standard field (or 4 nails with specific adhesive enhancement); deviation triggers a code-compliance hold. Metal roofs in Sebastian also require a wind-uplift calculation certified by a licensed Florida engineer if the system is exposed to gusts over 120 mph, which most coastal roofs are. This engineer's report costs $300–$600 and must be submitted with the permit.
Exemptions in Sebastian are narrow. Repairs that do NOT exceed 25% of the roof area AND involve like-for-like material (shingles replaced with identical shingles, no SWB addition, no layer count increase) may be exempt from full permitting — but the Building Department's definition of '25%' is strict. They calculate by roof square footage, not cost: a 2,000-sq-ft roof allows 500 sq ft of repair work unpermitted. Any work exceeding that threshold, or any project that adds a secondary water barrier or changes materials, requires a permit. Gutter, downspout, and flashing-only work is typically exempt if no structural deck penetration occurs. However, Sebastian's inspectors sometimes challenge whether a repair qualifies as exempt by re-inspecting the site after the work is complete; if they discover you've secretly added underlayment or installed SWB during a 'repair,' they may issue a citation and demand proof of permit compliance. The safest practice in Sebastian is to pull a permit for any work you're uncertain about; the $200–$400 permit fee is far cheaper than fighting an enforcement action.
Material changes — replacing asphalt shingles with metal, tile, slate, or composite — always require a permit and often trigger a structural evaluation. If your roof deck is questionable (visible rot, sagging rafters, previous water damage), a licensed structural engineer must certify that the new material's weight and fastening pattern are safe. Metal roofing is popular in Sebastian because of its wind resistance, but metal installation requires sealant specifications (typically silicone or polyurethane), fastener materials (stainless steel or galvanized, never bare), and spacing tolerances — all of which must appear in the permit drawing or specification sheet. Tile and slate are heavier and almost always require a structural check; the cost is typically $500–$1,200 for an engineer's report. Sebastian's Building Department cross-references these reports against the IRC R402 (structural capacity) and FBC 7-3-1302 (roof covering over existing structures), so missing or incomplete structural documentation is the #1 reason for permit denials on tile/slate conversions in this city.
The permit timeline in Sebastian depends on complexity. A standard asphalt-to-asphalt reroof with all specifications pre-filled (exposure class, SWB product, fastening pattern) can often be approved over the counter in 1–2 business days; the contractor walks in, the reviewer issues the permit same-day, and work can begin after the initial deck-inspection appointment. But most reroof permits get a standard 5–7 day plan-review cycle because reviewers verify the exposure classification, product specs, and underlayment coverage. If structural work is involved (deck repair, rafter reinforcement) or if you're changing materials, expect 2–3 weeks. Inspections are typically two-touch: a pre-tear-off inspection (to verify layer count and deck condition) and a final inspection after shingles/material is installed, flashing is sealed, and penetrations are closed. The final inspection also checks for proper SWB overlap, correct nail spacing, and gutter attachment. Plan for each inspection to be scheduled 1–2 business days out; back-to-back inspections compress the timeline to 5–7 days of actual calendar time.
Three Sebastian roof replacement scenarios
Why Sebastian's roofs cost more: FBC secondary-water-barrier rules and hurricane-wind exposure
Sebastian sits in a high-risk hurricane zone; the Atlantic coast of Brevard County is designated as Design Wind Speed 140+ mph in Suburban exposures and 145+ mph in Open Country. Because of this, Florida Building Code Section 7 (and the newer Section 8) impose secondary water barrier requirements that inland Florida cities (or cities in lower-wind zones) often waive or treat as optional. The specific rule is FBC 7-3-1202.1: 'Reroofing shall be done in the manner of new construction.' This means a reroof in Sebastian must include all the water-protection layers that a brand-new roof would have, including the SWB. Inland reroofs often skip SWB if the existing roof has no history of leaks — but Sebastian doesn't allow this exemption. The practical cost impact is $0.50–$1.50 per square foot for ice-and-water-shield or equivalent product; for a 1,800-sq-ft roof, that's $900–$2,700 in material and labor. No contractor in Sebastian can bid a reroof without including SWB; any bid that omits it is non-compliant and will be caught during permitting.
A second driver of cost is the fastening-pattern enforcement. In Open Country exposure, asphalt shingles must be nailed with 6–8 fasteners per shingle (vs. 4–6 in inland zones); metal roofs and tile systems require engineer-certified fastening layouts. The extra nails and labor are visible on the invoice, but the hidden cost is in plan review: if the contractor doesn't specify the fastening pattern in the permit application, the reviewer will request it, delaying approval. Some contractors outside Florida or unfamiliar with Sebastian's code try to submit generic 'per manufacturer' specs, which isn't specific enough for the city. The fix is a simple one-page drawing with fastener spacing shown; re-submission adds 5–7 days. Sebastian homeowners often discover this cost overrun when they get three roofing bids: the first two are ~20% cheaper because the contractors haven't accounted for SWB and plan-review labor; the third (from a local, Sebastian-familiar contractor) is higher and includes SWB, fastening-pattern drawing, and permit coordination. The premium is real but justified.
Material durability also justifies higher upfront cost in Sebastian. Asphalt shingles in a high-wind, high-UV zone (sandy coastal climate, intense sun, salt spray) degrade faster than inland equivalents. A 20-year-shingle in Sebastian often lasts 12–15 years; UV degradation and wind erosion accelerate failure. Metal and tile roofs cost 40–60% more upfront but last 30–50 years, making them cost-effective in Sebastian's harsh environment. Homeowners who plan to stay in their home for more than 10 years typically recover the metal upgrade cost through longevity and reduced maintenance. Permitting authorities in Sebastian implicitly encourage this by streamlining metal-roof permits relative to asphalt: metal roofs get plan approval in 5–7 days (same as asphalt) but with premium engineering review, whereas a questionable asphalt reroof can be held up by review comments.
How to navigate Sebastian's online permit portal and what the inspector will check
Sebastian's permit submission process uses an online portal (address and credentials available from the city's website or by phone). The portal requires an account (free, takes 10 minutes to create) and walks you through a multi-step form for roof work. Step 1 asks for property address and scope: 'Full replacement,' 'Partial replacement,' 'Repair,' etc. Step 2 asks for existing roof type (asphalt, tile, metal, etc.), number of existing layers, and any visible damage or leaks. Step 3 is the critical one for Sebastian: exposure classification. The form presents definitions of Open Country, Suburban, and Urban and asks you to select. The city's definitions are based on terrain, tree density, and nearby building density within a 1,500-foot radius. If you're unsure, the portal has a 'Contact the Reviewer' button; the city's plan reviewer will email back within 1 business day with a classification recommendation. Step 4 collects the proposed roof material, color, and product name (e.g., 'GAF Timberline HD, Charcoal') and asks for the secondary water barrier product (e.g., 'Grace Ice and Water Shield' or 'equivalent'). Step 5 requests a sketch or photo showing the SWB extent (typically 24 inches up from the eave, or 2 feet beyond the interior wall line). Uploading a smartphone photo is acceptable; the city doesn't require CAD. Step 6 asks about structural repairs (deck, rafters, etc.); if 'Yes,' you must upload an engineer's report or a narrative scope. Step 7 is contractor information: name, Florida license number, and proof of roofing license. If you're owner-builder, you'll declare this here; Florida Statute § 489.103(7) allows owner-builders to perform roofing on their own residential property, but you must still pull the permit yourself (contractor-pull is not an option for owner-builders in most jurisdictions, including Sebastian).
Once submitted, the portal generates a tracking number and sends an acknowledgment email. The form routes to a plan reviewer (turnaround: 1–5 business days for simple applications, 5–14 days for structural work). The reviewer will either approve, approve-with-conditions, or request additional information. Common request comments in Sebastian include: (1) 'Clarify exposure classification' (you've selected Suburban, but the reviewer sees open water nearby and wants confirmation), (2) 'Specify secondary water barrier product' (you've written 'ice-and-water shield, equivalent' but need to name the actual product), (3) 'Provide fastening-pattern sketch' (metal or tile roofs; asphalt often approved generically), and (4) 'Upload structural engineer report if deck repair is planned.' Once the reviewer approves, the portal sends a permit document (usually a PDF) to download and print. You'll take this to the job site; the inspector will verify the permit number before entering.
The pre-tear-off inspection is Sebastian's first touch. The inspector arrives (usually within 2 business days of your permit approval), walks the roof (or climbs it, depending on steepness), and uses a probe to verify the number of existing layers. If one layer is confirmed, the inspector approves tear-off. If three layers are detected, the inspector will note 'IRC R907.4 Violation: Three-layer maximum exceeded; tear-off required' — this halts overlay options and confirms your bid must include full tear-off. The inspector also checks for visible deck rot, rafter damage, and any active leaks. Photos are taken and uploaded to the city's file. If rot is spotted, the inspector will recommend a structural repair and ask you to contact an engineer. Most tear-offs begin within 3–5 days after this inspection. The final inspection occurs after shingles or material are installed but before the job is fully cleaned up. The inspector will climb (or scan with binoculars from the ground) and verify: (1) fastener spacing and pattern (spot-check of ~50 fasteners across the roof), (2) secondary water barrier seams and overlap (a crucial FBC check), (3) flashing at penetrations (vent boots caulked, chimney flashing properly sealed), (4) gutter attachment (if gutters are included), and (5) no debris or damage to adjacent surfaces. In Sebastian, this final inspection often takes 30–60 minutes; the inspector will flag any non-compliances on a checklist and either approve or request re-work. Approval means a signed-off permit and a digital final notice posted to the city's system.

Common questions
Do I need a permit for a simple shingle repair (patching a few damaged shingles)?
If you're replacing fewer than 10 damaged shingles in one area (roughly 50–100 sq ft on a typical roof) and not adding secondary water barrier, you likely don't need a permit — it's classed as maintenance. However, if you're tearing off and reinstalling the shingles (rather than just nailing new ones over old), or if the repair spans more than 100 sq ft, call the Building Department intake line for confirmation. In Sebastian, the safest rule is: repairs under 25% of roof area, like-for-like material, no SWB addition = exemption. Repairs over 25% always require a permit. When in doubt, the $225 permit fee is cheaper than a stop-work fine.
Can I use a roofing contractor from out of state, or must I hire a Florida-licensed roofer?
Florida law requires that anyone performing roofing work (including reroof tearoff and installation) hold a Florida roofing license under Florida Statutes § 489.117. An out-of-state contractor can only work under the supervision of a licensed Florida roofer on the job site. In practice, this means you must hire a licensed Florida roofing contractor to pull the permit and lead the work. The contractor's license number appears on the permit; if the city finds unlicensed work, they issue a stop-work order and fine the property owner. Sebastian's inspectors verify contractor licensing during the pre-tear-off inspection by checking the permit and asking for ID.
What if the inspector finds a third layer during tear-off? Am I stuck?
Yes, but you're protected. IRC R907.4 requires that if a third layer is discovered, you must stop work and perform a full tear-off (no overlay). Sebastian's inspectors are trained to probe for this before approving tear-off, so it should be caught at the pre-tear-off inspection. However, if it's discovered mid-work, you notify the city, request a re-inspection, and document the third layer with photos. The additional tear-off labor and disposal costs are typically $1.50–$3.00 per square foot. Your homeowner's insurance claim may cover this if the third layer was not disclosed at the initial property inspection; check with your adjuster. The permit fee remains the same; you don't pay extra to the city.
I'm owner-building. Can I pull the permit myself, or does a contractor have to do it?
Florida Statute § 489.103(7) allows an owner-builder to perform roofing on their own residential property. You can pull the permit yourself through the online portal (or in person at the city office). However, you must hold a Florida roofing license or work under the direct supervision of a licensed roofer who is present on-site during all work. If you're installing the roof yourself without a license, the city will not issue the permit. If you hire a roofing contractor to do the work, the contractor pulls the permit, not you. The key distinction: you can own the project and manage it, but the actual installation must be licensed.
Do I need a structural engineer's report for a metal-roof conversion?
Not always, but often. If your existing roof deck and framing are in good condition (no visible rot, no sagging), a metal-roof install can proceed without an engineer. However, if there's any doubt about deck condition, or if you're installing a heavy standing-seam metal system in an exposed location (Open Country, high-wind exposure), Sebastian's inspectors often require an engineer's report to certify structural capacity. Metal panels are lighter than tile but heavier than asphalt; the calculation is done to ensure nails, fasteners, and trusses can handle the load and wind uplift. Get a professional deck inspection ($150–$300) before finalizing the metal bid; if rot is found, engineer costs ($500–$1,200) are unavoidable.
How much does the permit cost in Sebastian?
Roof permits in Sebastian typically run $150–$450, depending on project scope. A straightforward asphalt-to-asphalt reroof on a 1,500–2,000 sq ft roof costs about $225–$300 (a base fee plus $0.10–$0.15 per sq ft). A material change (shingles to metal or tile) costs $300–$450 because of plan-review labor. If structural work is included (deck repair, engineer report), expect $400–$600. The fee is calculated and displayed in the online portal before you submit; no surprises. Permit fees are non-refundable, even if the project is cancelled after approval.
What is 'secondary water barrier' and why does Sebastian require it on every reroof?
Secondary water barrier (SWB) is a self-adhesive membrane (ice-and-water shield) that sticks to the roof deck underneath the shingles or metal. It's a backup layer that catches water that might sneak under the primary layer (shingles) during heavy rain or wind-driven spray. In Sebastian's high-wind coastal environment, wind gusts can temporarily lift shingles and allow water intrusion; SWB catches this water and channels it to the gutter. FBC 7-3-1202 requires SWB on all reroofs in Sebastian because of hurricane-wind exposure. It costs $0.50–$1.50 per sq ft (material + labor) and typically extends 24 inches up from the eave, or 2 feet beyond the interior wall line, whichever is greater. Your contractor must specify the SWB product name (e.g., 'Grace Ice and Water Shield, 3' roll') in the permit.
Can I do a reroof overlay (new shingles over old) in Sebastian, or must I tear off?
Overlay is allowed only if there is one existing layer and no structural issues are present. If your roof has two or more layers, a tear-off is mandatory per IRC R907.4. Even with one layer, if the deck is soft, warped, or compromised, tear-off is required. Sebastian's inspectors probe the deck at the pre-tear-off inspection to determine this. Many roofing contractors recommend tear-off anyway because it allows a fresh inspection of the deck (and catches hidden rot early), improves ventilation, and extends the new roof's lifespan. Overlay saves $1.00–$2.00 per sq ft in labor and disposal but costs more long-term if the deck later needs repair. In Sebastian's humid coastal climate, hidden deck rot is common; tear-off is the safer bet.
How long does the entire permit-to-completion process take in Sebastian?
A standard asphalt-to-asphalt reroof: 10–14 calendar days from permit submission to final inspection. This breaks down as: 1 day for online application, 2–5 days for plan review (usually 2–3 for simple projects), 1 day for permit download/print, 2 days before pre-tear-off inspection is available, 3–4 days for tear-off and installation (weather dependent), and 1 day for final inspection scheduling. Total: roughly 10–14 calendar days. A material change (shingles to metal) or structural repair can push this to 3–4 weeks because plan review takes longer (7–14 days) and an engineer's report must be obtained and submitted. Weather delays are common in Sebastian; rain halts roof work, so timeline can extend by a week or more during rainy season (June–September).
What happens if I hire a contractor who doesn't pull the permit?
You, as the property owner, are liable. If the city discovers unpermitted roof work (via complaint, satellite imagery review, or routine inspection), a stop-work order is issued to you, not the contractor. You're fined $500–$1,500 and must either pull a retroactive permit (paying the original fee plus a penalty) or have the work removed entirely. Additionally, unpermitted work cannot be insured; if the roof fails due to improper installation and your insurance learns the work was unpermitted, your claim will be denied. Most importantly, unpermitted roof work must be disclosed when you sell the home, which will spook buyers and lenders. The moral: always verify that your contractor has pulled the permit before work starts. Ask to see the permit document and tracking number from the city; don't accept the contractor's word. If they refuse to pull a permit, hire a different contractor.
