Okla. Stat. tit. 59, § 59-1151.22: Workers compensation insurance coverage

A. Any contract entered into under the Roofing Contractor

Registration Act shall include a statement that all individuals

performing work under the contract are covered by workers'

compensation insurance.

B. If an affidavit of exemption for workers' compensation

insurance is used by a legitimately exempt person, it shall be

attached to the contract and it shall be used only for residential

construction projects. All commercial projects shall require all

individuals performing work on such project to be covered by

workers' compensation insurance as employees of the person

registered under the Roofing Contractor Registration Act. However,

any day laborer who can show proof of being covered by workers'

compensation insurance under the temporary labor agency for whom he

or she is hired-out may provide an affidavit from the temporary

labor agency to meet the requirement of this section for authority

to use an affidavit of exemption. No roofing contractor required to

be registered under the Roofing Contractor Registration Act shall

hire any out-of-state company or person or use any person or

independent contractor that is not registered under the Roofing

Contractor Registration Act with the required workers' compensation

insurance or who is not deemed his or her employee for purposes of

workers' compensation insurance.

C. In no event shall a homeowner be held liable in the workers'

compensation administrative system for injury or death to any person

who performs work under a contract with a person required by law to

be registered under the Roofing Contractor Registration Act and have

workers' compensation insurance on all persons performing work on

the roofing project.
