OK Roofing Contractor cheat sheet

Oklahoma roofing contractors register with the Construction Industries Board (CIB); roofing is a registration category, not a statewide license like electrical or plumbing.

Registration requires a designated responsible party who passes the CIB roofing exam, plus proof of general liability insurance and workers' compensation coverage or an approved exemption.

A roofing registration is tied to the named qualifier; if that individual leaves the company, the firm must notify CIB and qualify a replacement within the allowed window.

Registration must be renewed on the CIB cycle; operating with a lapsed registration exposes the contractor to administrative penalties and contract-enforcement risk.

Soliciting or performing roofing work without a valid registration is a violation enforceable by CIB, and municipalities may add their own local permit and registration layers.

Contractors must display or provide their registration number where required and use it on permits, bids, and contracts as proof of compliant status.

Workers' compensation exemption requires a CIB-approved filing (e.g., a notarized affidavit for qualifying owners); a lapsed policy must be reported and coverage restored.

Business-entity changes (name, ownership, address) are reportable updates; failure to keep CIB records current can void the registration.

Steep-slope shingle underlayment: minimum one layer over the deck, with a doubled (two-ply) self-adhering membrane required at eaves per code in ice-dam or cold-climate exposures.

Asphalt shingle fastening: typically four nails per shingle, six in high-wind zones, placed in the manufacturer's nail zone; high-nail placement voids wind warranties.

Minimum roof slope for standard shingles is 2:12 with underlayment; below 2:12 requires a low-slope membrane system, not shingles.

Metal panel systems rely on correct clip spacing, thermal movement allowance, and butyl or EPDM closure at fasteners to prevent leaks.

Flashing details at valleys, step flashing at walls, and counterflashing at chimneys are the highest-risk leak points; open valleys require metal or membrane lining.

Ventilation balance rule: intake (soffit) net free area should roughly equal exhaust (ridge/hip) net free area; 1:150 ratio of vent area to attic floor area is the baseline.

Tile and slate systems need a minimum slope, a secondary water barrier, and fasteners rated for the load; weight affects structural deck requirements.

TPO/EPDM low-slope membranes: seam integrity, proper adhesive or heat-weld temperature, and tapered insulation for positive drainage to drains and scuppers.

Oklahoma adopts the International Residential Code (IRC) and International Building Code (IBC) through the Oklahoma Uniform Building Code Commission (OUBCC), with state amendments.

Roof covering requirements for one- and two-family dwellings sit in IRC Chapter 9; commercial roofing provisions sit in IBC Chapter 15.

Local jurisdictions may adopt more recent code editions and amendments; always confirm the edition in force in the specific AHJ before permitting.

Code updates follow a cycle; when a new edition is adopted, permit applications filed after the effective date must comply with the new edition.

Reroofing over existing shingles is limited by code (typically one additional layer maximum) and requires sound decking and proper fastening through to the deck.

Ice barrier, drip edge, and underlayment requirements are code-minimum; manufacturer instructions control when they are more stringent.

Permits and inspections are required for reroofing and structural roof work; final inspection confirms flashing, ventilation, and covering compliance.

Energy code provisions affect roof insulation and cool-roof reflectance for commercial buildings; verify local amendments for climate-zone requirements.

Oklahoma's home repair/roofing consumer protections limit advance deposits and require written contracts with scope, materials, price, and payment schedule.

A written contract should state the contractor's CIB registration number, insurance coverage, start and completion dates, and change-order procedure.

Insurance-claim roofing: the contractor may not act as a public adjuster; homeowners should not be asked to sign over policy rights or pay deductibles illegally.

Lien rights: subcontractors and suppliers can file mechanics' liens; obtaining lien waivers at each payment protects the homeowner and the contractor.

Three-day right to cancel applies to certain door-to-door or home-solicitation contracts under Oklahoma consumer protection law.

Advertising and bids must be accurate; deceptive practices, unlicensed solicitation, and storm-chasing scams are actionable under the Oklahoma Consumer Protection Act.

Payment schedules should tie draws to completed milestones, and final payment should follow final inspection and punch-list completion.

Recordkeeping: retain contracts, permits, change orders, and warranty documents for the statutory period to defend claims and support warranty service.

OSHA fall protection: residential steep-slope work generally triggers fall protection at 6 feet; guardrails, personal fall-arrest systems, or safety nets are options.

Ladder safety rule: 3-point contact, 4:1 slope for extension ladders, and extend 3 feet above the landing surface.

Workers' compensation coverage is mandatory for covered employees in Oklahoma; misclassifying employees as independent contractors creates liability.

Employees must be at least 16 for general construction; minors face restrictions on hazardous roofing tasks and powered equipment.

Personal protective equipment: hard hats, eye protection, gloves, and fall-arrest harnesses inspected before each use; damaged equipment must be removed from service.

Heat-illness prevention: water, rest, shade, acclimatization, and monitoring for heat stress are core to summer roofing safety programs.

Jobsite housekeeping and roof-edge control: secure materials, keep walkways clear, and use toe boards or debris nets to protect workers below.

Tool and equipment safety: nail guns require trigger discipline and eye protection; propane kettles and torches require fire watch and clearance from combustibles.
