Why Oklahoma Roofing Codes Are Complex
Situated in the heart of Tornado Alley, Oklahoma needs roofing that withstands tornado-force winds, hailstorms, ice events, and flash flooding. Regulations differ by city and county, with stricter code enforcement in storm-prone areas (as you'd imagine). Arm yourself with the right documentation when you are adding new shingles or a new roof.
Tornado-Force Winds
- Building codes in Oklahoma require roofing systems built for high wind uplift resistance, compliant with ASCE 7 and ASTM D7158 or D3161
- In particularly vulnerable areas, additional fasteners or hurricane clips may be required to maintain structural integrity.
Hailstorms
- Oklahoma consistently ranks among the top states for hail damage, prompting building and insurance standards that favor impact-resistant (Class 4) shingles. leveraging durability for cost savings and compliance.
Temperature Swings
- Rapid changes in temperature lead to material expansion and contraction, causing cracks or warping on an old roof. Flexible and well-installed roofing materials combat climate. Code protocols emphasize effective flashing and ventilation to prevent premature failure.
Heavy Rainfall & Flash Flooding
- Frequent heavy rains and flash flooding underscore the importance of proper roof drainage slope and moisture-resistant systems. Oklahoma codes are designed to protect structure and safety.
