Registration details
- state_level: Roofing contractor is a separately licensed trade in Florida. Section 489.105(3)(e), Florida Statutes, defines a "Roofing contractor" as "a contractor whose services are unlimited in the roofing trade"; section 489.113(2) provides that a person "must be certified or registered in order to engage in the business of contracting in this state." A state-certified contractor may work statewide; under section 489.117(1)(b), "Registration allows the registrant to engage in contracting only in the counties, municipalities, or development districts where he or she has complied with all local licensing requirements, if any, and only for the type of work covered by the registration." Section 489.103(7) contains an owner-builder exemption for "Owners of property when acting as their own contractor and providing direct, onsite supervision themselves of all work not performed by licensed contractors"; this record does not decide whether a particular reader falls within it.
- county_level: County Code section 26-81 makes it "unlawful for any person to carry on the trade or business of general contractor, building contractor, residential contractor, sheet metal contractor, roofing contractor, air conditioning contractor, mechanical contractor, pool contractor, electrical contractor, plumbing contractor, solar contractor or specialty contractor in Columbia County, Florida unless such person has been issued a certificate of competency by Columbia County, Florida for such trade or business." Under section 26-83 an applicant qualifies with a current State of Florida certified licence, a State registered licence in good standing in Union, Gilchrist, Hamilton or Suwannee County, or a passing grade of 75 percent on a registered exam at a County-approved testing facility. The County's Registered Contractor's Fee Schedule (published 10/2025) states that "Contractors with expired registrations may not be eligible to pull permits until renewal (and penalty) is satisfied," and sets minimum liability insurance by licence category. Section 26-87 preserves the owner-builder exemption in section 489.103, Florida Statutes, provided the owner "must personally appear and sign the building permit" and submit the owner builder disclosure statement. Licensed contractors file a Contractor Roofing Affidavit after the in-progress inspection; the affidavit is "NOT REQUIRED FOR OWNER BUILDERS."
Permit process note
A re-roof in unincorporated Columbia County is permit work unless its cost is $5,000 or less. County Code section 26-35(a) makes it "unlawful for any person, firm or corporation to construct, erect, alter or repair any building within the territory embraced by the terms of this article without first obtaining a permit therefor from the county building inspector," and exempts "All construction where the cost of the same does not exceed $5,000.00, unless otherwise required by the Florida Building Code" (as amended by Ord. No. 2025-05, February 20, 2025). The County publishes a separate Roof Replacement or Repair Application, whose checklist covers "Reroofs ~ Roof Repairs ~ Roof Overs," residential or commercial, and states: "If the construction job cost is $5000 or less, no permit is required. (County Ord. 2025-05) This does not change the requirement for the use of licensed contractors and the requirement of recording a Notice of Commencement when the cost is $5000 or more." It adds that "it is highly recommended that a permit be pulled regardless of the cost for insurance purposes." The County's re-roof procedures sheet (published 10/2025) states: "Permit must be issued before work begins." Applications are submitted online or on paper; walk-in submittals need the Product Approval Code Specifications Form and the Roofing Underlayment Affidavit, and the deeded property owner must sign page 2 of the application. A recorded Notice of Commencement is needed before the first inspection. State law makes it "unlawful for any person, firm, corporation, or governmental entity to construct, erect, alter, modify, repair, or demolish any building within this state without first obtaining a permit" (section 553.79(1)(a), Florida Statutes). County Code section 26-39 makes a violation a misdemeanor punishable by "a fine not to exceed $500.00, or by imprisonment in the county detention center for a term not to exceed 60 days, or by both."
Inspection requirements
The County's re-roof procedures (published 10/2025) run in four steps: submit the re-roof permit application; schedule the in-progress inspection ("Request inspection at least 24 hours in advance"); upload the Contractor Roofing Affidavit (licensed contractors) and roof photographs to the permit record ("Owner-Builders: Affidavit not required, but photos are still required"); then schedule the final inspection, after which "your Certificate of Completion will be issued." For all re-roof permits, "Every photo must show the permit number" and a "Measuring tape must be visible in nailing/lap pattern photos"; the checklist covers sheathing nailing and repairs before covering, underlayment nailing and lapping, valleys, drip edge and flashings, vent openings, the shingle nailing pattern, metal roof overlays and final cleanup. The Contractor Roofing Affidavit affirms that "the sheathing, nailing, dry-in, venting, and flashings at the above referenced address will be installed in accordance with the applicable codes." The County's fee schedule charges $50 for re-inspections.
Adopted code
Florida Building Code, 8th Edition (2023), Residential volume (2021 International Residential Code base), effective December 31, 2023, adopted statewide by the Florida Building Commission under Rule 61G20-1.001, Florida Administrative Code; section 553.73(6), Florida Statutes, provides that the code and each update "is deemed adopted for use statewide without adoptions by local government." County Code section 26-33 (Ord. No. 2012-2) adopts "The Florida Building Code, and the National Electrical Code, including all future additions and revisions thereto, as may be adopted by the State of Florida," and the County's permit application names "2023 Florida Building Code 8th Edition and the 2020 National Electrical Code." The County's former amendments to the Florida Building Code (sections 26-40 and 26-41, Ord. No. 2018-09) were repealed by Ord. No. 2025-05 on February 20, 2025. County Code Chapter 26, Buildings and Building Regulations, read in full, contains no roofing technical provisions; its section 26-36 sets design wind speeds (see the wind design field).
Drip edge
Required — Florida Building Code, Residential, 8th Edition (2023), section R905.2.8.5 Drip edge: "Provide drip edge at eaves and gables of shingle roofs. Overlap to be a minimum of 3 inches (76 mm). Eave drip edges shall extend 1/2 inch (13 mm) below sheathing and extend back on the roof a minimum of 2 inches (51 mm). Drip edge shall be installed over the underlayment." The requirement is written for shingle roofs. County Code Chapter 26 (read in full) does not amend it, and the County's required re-roof photo checklist includes "valley materials, drip edge, and flashing around pipes/chimneys (show nails & sealants)."
About drip edge
Ice & water shield
Not required — Not required. The Florida Building Code, Residential, 8th Edition (2023) reads "R905.1.2 Ice barriers. Reserved." and, for asphalt shingles, "R905.2.7 Ice barrier. Reserved." County Code Chapter 26 (read in full) adds no ice barrier. The County's Roofing Underlayment Affidavit offers, as one of the options for sealing the roof deck, "A self-adhering polymer-modified bitumen underlayment complying with ASTM D1970 applied over the entire roof"; it is permitted, not required.
About ice & water barrier
Mid-roof inspection
Required — The County's re-roof procedures sheet (published 10/2025) lists "Step 2 - Schedule In-Progress Inspection": "Crew must be actively working or roof must be clearly under construction" and "Inspector will conduct this inspection on-site." After it, licensed contractors upload the Contractor Roofing Affidavit and every permit uploads roof photographs before the final inspection. The Florida Building Code, Building, section 110.3 also lists a "Roofing inspection" that "Shall at a minimum include the following building components," listed as dry-in, insulation, roof coverings and flashing.
Impact-resistant roofing
Not required — County Code Chapter 26 (read in full, including its Building Code Ordinance, sections 26-31 through 26-41) does not amend the roofing chapters, and its former amendments to the Florida Building Code were repealed in 2025; no UL 2218 or Class 4 impact requirement appears in the Florida Building Code, Residential Chapter 9, Building Chapter 15 or Existing Building Chapter 7 as they apply in unincorporated Columbia County. Florida's shingle classes under section R905.2.6.1 (ASTM D3161, TAS 107, ASTM D7158) are wind ratings, not impact ratings.
Repair permit threshold
County Code section 26-35(a)(2) (Ord. No. 2025-05, February 20, 2025) exempts from the permit "All construction where the cost of the same does not exceed $5,000.00, unless otherwise required by the Florida Building Code." The County's No Permit Required Form restates it: "If the construction job cost is $5,000.00 or less, no permit is required. This does not change the requirement for the use of licensed contractors and the requirement of recording a Notice of Commencement when the job cost is over $5,000.00 for building construction," and is issued on a bid proposal and a Property Appraiser printout. A full re-roof costing more than $5,000 needs a permit. Since July 1, 2026, section 553.79(1)(g), Florida Statutes, also reads: "A local government that issues building permits shall exempt an owner of a single-family dwelling or the owner's contractor from the requirement to obtain a building permit to perform any work valued at less than $7,500 on the owner's property." It does not apply to "Work on a property that is partially or entirely located in a flood hazard area" or to "Any electrical, plumbing, structural, mechanical, or gas work," requires "a written request for exemption to the local enforcement agency with a copy of the contract," and provides that "A construction project may not be divided into more than one project for the purpose of evading the requirements of this paragraph." The Florida Building Code's own relief, Building section 105.2.2, allows "Ordinary minor repairs" without a permit only "with the approval of the building official." Separately, the Florida Building Code's 25 percent rule applies to roof repairs (see the deck and sheathing field).
Wind design criteria
County Code section 26-36, Designated wind zones (Ord. No. 2012-2): "The following wind zone areas are adopted as required by the Florida Building Code, and specified by the Florida Building Code and ASCE7." Risk Category II buildings, which include ordinary houses, are listed at "115 miles per hour, north of centerline of CR 240 (parts of aka Myrtis & Family Road); and 120 miles per hour, south of CR 240"; Risk Category I at 105 and 110 mph and Risk Categories III and IV at 120 and 130 mph on the same line. "Linear interpolation is permitted in all areas when done in accordance with ASCE 7 and certified under seal." The section dates from 2012; the Building Department also publishes a Wind Speed Maps document in its document library. Columbia County is not in the High-Velocity Hurricane Zone, which the Florida Building Code defines as Broward and Miami-Dade counties.
Roof layer limit / recover
Florida Building Code, Residential, 8th Edition (2023), section R908.3 Recovering versus replacement: "New roof coverings shall not be installed without first removing all existing layers of roof coverings where any of the following conditions occur: 1. Where the existing roof or roof covering is water soaked or has deteriorated to the point that the existing roof or roof covering is not adequate as a base for additional roofing. 2. Where the existing roof covering is wood shingle or shake, slate, clay, cement or asbestos-cement tile. 3. Where the existing roof has two or more applications of any type of roof covering." A single re-cover over one existing layer is therefore the most the code allows. County Code Chapter 26 (read in full) states no layer limit of its own and does not amend section R908.3; the County's roofing application covers "Roof Overs" under the same permit.
Deck & sheathing requirements
Florida Building Code, Residential, 8th Edition (2023), section R908.7 Wind mitigation: "When a roof covering on an existing structure with a sawn lumber, wood plank or wood structural panel roof deck is removed and replaced, the following procedures shall be permitted to be performed by the roofing contractor: (a) Roof-decking attachment shall be as required by Section R908.7.1. (b) A secondary water barrier shall be provided as required by Section R908.7.2. Exception: Structures permitted subject to the Florida Building Code are not required to comply with this section." Section R908.1.1 (the 25 percent rule): "Not more than 25 percent of the total roof area or roof section of any existing building or structure shall be repaired, replaced or recovered in any 12-month period unless the roof covering on the entire existing roof system or roof section is replaced or recovered to conform to the requirements of this code," with an exception for roofs built, repaired or replaced under the 2007 Florida Building Code or later. In Columbia County, the Roofing Underlayment Affidavit requires the roofer or owner-builder to select an option "for sealing the roof deck" under the 2023 code (a full self-adhered ASTM D1970 underlayment; 4-inch self-adhered strips over all deck joints with felt or synthetic underlayment over them; or two layers of felt or synthetic underlayment), and the required re-roof photographs include "Sheathing nailing and repairs before covering."
Sales & use tax
7.5% combined: 6% Florida state sales and use tax plus Columbia County's 1.5% discretionary sales surtax, which the Department of Revenue's Form DR-15DSS for calendar year 2026 lists as two levies, 1% effective August 1, 1994 with no expiration date and 0.5% effective January 1, 2023 with an expiration date of December 31, 2042. Per the Department, the surtax "applies to the first $5,000 of the sales amount on the sale, use, lease, rental, or license to use any item of tangible personal property." Under Rule 12A-1.051, Florida Administrative Code, "Roofing work" is a real property contract, and "Contractors are the ultimate consumers of materials and supplies they use to perform real property contracts and must pay tax on their costs of those materials and supplies, unless the contractor has entered a retail sale plus installation contract"; such contractors "should charge no tax to their customers, regardless of whether they itemize charges for materials and labor in their proposals or invoices." The rate is the roofer's cost on materials, repair and replacement alike, not a tax charged to the homeowner.
