Timed practice can help candidates become more efficient with a large examination reference library.

State Requirements

Oklahoma requires roofing contractors to maintain a valid registration through the Oklahoma Construction Industries Board to engage in or offer roofing-related services covered by the Roofing Contractor Registration Act.

A roofing registration that allows residential work and is in good standing is required before a Commercial Endorsement can be approved. Contractors performing commercial roofing work must obtain the Commercial Endorsement unless the work falls within an applicable statutory exemption.

Commercial roofing contractors must provide proof of at least $1,000,000 in commercial general liability insurance. The applicable certificate of insurance must satisfy Oklahoma Construction Industries Board requirements for commercial roofing work.

Applicants must also provide proof of compliance with applicable Oklahoma workers' compensation requirements or documentation supporting an allowable exemption.

Oklahoma requires roofing contractor registration and any Commercial Endorsement to be renewed annually. Commercial roofing qualifying parties are also subject to continuing-education requirements.
