The required wind load rating depends on your specific location, local building codes, and insurance requirements. The most accurate way to determine your needs is to use our Wind and Snow Load Tool, which calculates requirements based on your exact address using ASCE Hazard data. Alternatively, you can contact your local building department for minimum code requirements.

Certified buildings undergo engineering analysis and are designed to meet specific wind load requirements according to building codes. They come with documentation verifying their compliance, which is often required for building permits and insurance. Non-certified buildings may be less expensive initially but lack verification of their wind resistance capabilities and may not meet local code requirements, potentially leading to permit issues, insurance problems, or structural failure.

Yes, existing structures can often be reinforced for improved wind resistance. Common upgrades include:

• Adding additional anchors
• Installing reinforcement braces
• Upgrading to heavier gauge framing at stress points
• Converting to vertical roof panels
• Adding gusset plates at connections

Yes, metal buildings and carports installed with a vertical roof offer superior wind load ratings, as they allow wind to flow more efficiently over the structure and the design reduces uplift pressure by directing wind forces downwards.

Concrete anchoring provides the strongest wind resistance for metal buildings. We recommend:

• Mobile home anchors for temporary installations (minimum 30″ depth)
• Concrete anchors for permanent installations (embedded in 4″+ thick concrete)
• Increased anchor quantity in high-wind zones (typically 25-50% more than standard)
• Corner reinforcement anchors to prevent twisting

Our engineering team can provide specific anchoring recommendations based on your location’s wind requirements. Get a quote today.

Areas prone to hurricanes and tornadoes require specialized considerations:

• Hurricane zones typically require wind ratings of 140-170 mph
• Tornado-prone regions benefit from enhanced anchoring systems
• Both require closer frame spacing (typically 4′ vs. standard 5′)
• Additional roof bracing is recommended
• Heavier gauge materials may be required

Our structures for these regions include multiple reinforcement features and come with appropriate certifications for insurance purposes.

Yes, significantly. Larger buildings create more surface area for wind to push against, requiring more robust engineering. Additionally:

• Taller buildings experience stronger winds and greater leverage effects
• Wider buildings may require additional central supports
• Longer buildings need more lateral bracing to prevent racking
• The ratio of height to width affects aerodynamic performance

Our engineers account for all dimensional factors when designing wind-resistant structures.

Regular maintenance preserves your building’s wind resistance capabilities:

• Inspect and tighten all fasteners annually
• Check anchoring systems after major storms
• Examine frame components for any bending or stress
• Replace any damaged or missing panels promptly
• Clear debris from roof and gutters
• Ensure doors and openings close securely

We recommend an inspection every 2-3 years in high-wind regions.

Yes, carports can  withstand high winds up to 180 MPH, if they are engineered properly.
