New Residential Roofing Endorsement Required by House Bill 1628
By Tony DeSha
On May 28, 2025, Governor Kevin Stitt signed House Bill 1628 into law, bringing significant changes to the roofing industry in Oklahoma. Effective July 1, 2026, the law introduces a new Residential Roofing Endorsement requirement for roofing contractors working on residential projects.
This legislation establishes testing requirements for Residential Endorsement, increases registration costs, removes the first-offense warning for violations of the Roofing Contractor Registration Act, and includes a grandfathering provision for contractors currently in good standing with the Construction Industries Board.

The 12-month grandfathering period ends on July 1, 2027. After that date, all individuals seeking a Residential Roofing Endorsement will be required to apply and pass the residential endorsement exam.
Temporary Exemption for Commerically Endorsed Roofers (Until July 1, 2027):
Contractors who currently hold a valid Commercial Roofer Endorsement are exempt from the residential endorsement exam/continuing education requirements during the grandfathering period. However, they must still submit an application and pay the required fee to obtain the Residential Roofing Endorsement.
Important: After July 1, 2027, even commercially endorsed roofers will be required to pass the residential roofing exam in order to obtain the residential endorsement.
