OK Roofing Contractor flashcards

33 cards. Read the term and the definition here. The deck at the top of this page is optional.

CIB roofing registration

Oklahoma's Construction Industries Board registers roofing contractors. Registration requires a qualifying individual, insurance, and compliance with state renewal and reporting rules; it is not a statewide license.

Responsible party qualifier

The individual who passes the CIB roofing exam and is tied to the firm's registration. If that person leaves, the company must qualify a replacement to keep the registration valid.

Registration renewal cycle

CIB registrations expire on a set cycle and must be renewed with proof of current insurance and workers' compensation. Operating on a lapsed registration risks penalties and contract disputes.

Workers' comp exemption filing

Qualifying owners may file a CIB-approved exemption, often a notarized affidavit. A lapsed policy must be reported and coverage restored to keep registration in good standing.

Unregistered contracting violation

Performing or soliciting roofing work without CIB registration is enforceable by the state, and municipalities may impose separate local registration and permit requirements on top.

Reportable business changes

Changes to a roofing firm's name, ownership, or address must be reported to CIB. Failing to keep records current can invalidate the registration and permit approvals.

Two-ply eave underlayment

Code requires a doubled self-adhering membrane at eaves in ice-dam or cold-climate exposures, plus at least one underlayment layer over the roof deck.

Shingle nail placement

Typically four fasteners per shingle, six in high-wind zones, driven in the manufacturer's nail zone. High nails miss the nailing strip and void wind warranties.

Minimum shingle slope

Standard asphalt shingles require at least a 2:12 slope with underlayment. Roofs below 2:12 need a low-slope membrane system instead of shingles.

Ventilation balance rule

Intake soffit net free area should roughly match exhaust ridge or hip vent area. The baseline ratio is about 1:150 of vent area to attic floor area.

Valley and step flashing

Valleys, wall step flashing, and chimney counterflashing are the highest-risk leak points. Open valleys require metal or membrane lining installed in the correct sequence.

Metal panel thermal movement

Metal roof panels expand and contract with temperature. Correct clip spacing, fastening details, and closure strips accommodate movement and prevent fastener leaks.

Low-slope membrane seams

TPO and EPDM roofs depend on seam integrity through proper adhesive or heat-weld temperature, plus tapered insulation that directs water to drains and scuppers.

Tile secondary barrier

Tile and slate systems need minimum slope, a secondary water barrier under the tile, and fasteners rated for load. Their weight affects structural deck design.

OUBCC code adoption

Oklahoma adopts the IRC and IBC through the Oklahoma Uniform Building Code Commission with state amendments. Local jurisdictions may adopt newer editions and amendments.

IRC Chapter 9 roofing

Roof covering requirements for one- and two-family dwellings appear in IRC Chapter 9. Commercial roofing provisions appear in IBC Chapter 15.

Reroof over existing shingles

Code limits reroofing over existing shingles, typically one additional layer maximum, and requires sound decking and fasteners that reach through to the deck.

Permit and inspection duty

Reroofing and structural roof work require permits and inspections. Final inspection confirms flashing, ventilation, and covering compliance before sign-off.

Manufacturer over code rule

Ice barrier, drip edge, and underlayment are code minimums. When manufacturer installation instructions are stricter, the manufacturer's requirements control the installation and warranty.

Code edition effective date

When a new code edition takes effect, permit applications filed after that date must comply with the new edition, including local amendments in force.

Commercial cool-roof rules

Energy code provisions govern roof insulation and cool-roof reflectance for commercial buildings. Verify local amendments for climate-zone-specific requirements before specifying.

Written roofing contract

Oklahoma consumer protections require written contracts stating scope, materials, price, payment schedule, CIB registration number, insurance, and start and completion dates.

Contractor not public adjuster

A roofing contractor cannot act as a public adjuster. Homeowners should not sign over policy rights or be asked to pay deductibles improperly on insurance claims.

Mechanics lien and waivers

Suppliers and subcontractors can file mechanics' liens on improved property. Collecting lien waivers at each draw protects the homeowner and documents payment.

Three-day cancellation right

Certain door-to-door or home-solicitation contracts give Oklahoma homeowners a three-day right to cancel. The contract must disclose that right.

Consumer Protection Act

Oklahoma's Consumer Protection Act reaches deceptive bids, false advertising, unregistered solicitation, and storm-chasing scams that harm homeowners.

Milestone payment schedule

Draws should be tied to completed milestones, with final payment after final inspection and punch-list completion. This reduces payment disputes and lien exposure.

OSHA six-foot trigger

Residential steep-slope roofing generally triggers fall protection at six feet. Guardrails, personal fall-arrest systems, or safety nets satisfy the requirement.

Extension ladder 4:1 rule

Extension ladders use a 4:1 slope, extend three feet above the landing, and require three-point contact. Inspect rungs and feet before each use.

Employee misclassification risk

Oklahoma requires workers' compensation for covered employees. Labeling employees as independent contractors creates liability, penalties, and coverage gaps on roofing crews.

Minor worker restrictions

Employees must generally be at least 16 for construction. Minors face restrictions on hazardous roofing tasks and powered equipment under labor rules.

Heat illness prevention

Summer roofing safety requires water, rest, shade, acclimatization for new workers, and monitoring for heat stress symptoms on the crew.

Nail gun and torch safety

Nail guns require trigger discipline and eye protection. Propane kettles and torches require a fire watch and clearance from combustible materials.
