How far apart you screw metal roofing depends on the type of system you use. Most metal roofing requires screws placed 12 to 24 inches apart, depending on wind speed and local building codes. Proper screw spacing keeps your roof secure and helps it last longer. Metal roofing is growing in popularity because it lasts 40 to 80 years, much longer than asphalt shingles which last only 20 to 30 years. According to RubyHome, metal roofing installation costs between $10 and $17.05 per square foot. Getting the screw spacing right is key to protecting your home from leaks and wind damage.
Why Screw Spacing Matters
Screws hold your metal roofing panels in place. If they are too far apart, wind can lift and damage the roof. If they are too close, you waste money and may crack the metal.
Building codes tell you the right spacing for your area. Coastal regions with high winds need screws closer together. Inland areas may allow wider spacing.

Standard Screw Spacing Guidelines
Most metal roofing uses one of these spacing methods:
- Ribs: 12 inches apart on the ribs
- Purlins: 16 to 24 inches apart along purlins
- Fasteners: Follow your roof manufacturer’s guide
- Wind zones: Up to 9 inches apart in extreme wind areas
Climate and Weather Impact
Your location matters. According to the Insurance Information Institute, in 2024, 12 million U.S. properties were hit by hail. High-wind areas need closer screw spacing to stay safe.
Hot climates also affect metal roofing. Light-colored metal shingles work better in hot climates. According to RubyHome’s roof lifespan data, metal roofing can last 40 to 80 years when installed correctly.
Installation Tips for Best Results
Use the right screws. Stainless steel or galvanized screws resist rust. Never skip fasteners or space them too wide.

Check your local building codes before starting. According to IBISWorld, the U.S. roofing contractor industry reached $81.3 billion in 2025. Professional roofers know the exact rules for your area. Getting it wrong can cause leaks and void your warranty. Always follow the metal roofing manufacturer’s instructions for the best protection and longest roof life.
