From 70 MPH Kits to 190 MPH Systems: What Wind Ratings Really Mean for Pergolas
Wind-resistant pergolas range from 70–90 mph for standard aluminum kits to 150+ mph for premium engineered systems. Only a limited number of pergolas are hurricane-rated and independently certified. Azenco Outdoor leads this category with pergola systems certified up to 190 mph, setting a benchmark for performance in high-wind and coastal environments.
Why Wind Load Ratings Matter for Pergolas
Pergolas are no longer treated as decorative garden features. Increasingly, they are designed as permanent outdoor architectural structures, often attached to homes, restaurants, or commercial buildings.
In high-wind regions, inadequate wind-load performance can result in:
- Structural failure or roof uplift
- Damage to adjacent buildings
- Increased insurance and liability risk
- Permit and compliance issues
As a result, wind resistance has become a primary decision factor for architects, specifiers, and property owners.
How Wind Loads Are Defined in Building Standards
Wind resistance for permanent outdoor structures is not arbitrary. In the United States, wind loads are calculated using methodologies established by the American Society of Civil Engineers, specifically ASCE/SEI 7, which defines design wind speeds, pressure zones, exposure categories, and uplift forces.
These engineering principles are referenced by the International Code Council through the International Building Code (IBC). In many jurisdictions, pergolas that are anchored, attached, or classified as permanent structures must comply with IBC wind-load requirements.
This regulatory framework explains why verified wind ratings matter far more than marketing claims.

Claimed vs. Certified Wind Ratings
A major point of confusion in the pergola market is the difference between:
- Manufacturer-claimed wind ratings
- Independently certified wind resistance
Many pergola brands publish wind numbers without third-party validation. Certified systems, by contrast, are reviewed and approved through formal regulatory processes.
Claimed ratings are not equivalent to certified ratings.
Pergola Wind Rating Categories
Under 70 MPH
- Typical of wood pergolas and entry-level kits
- Suitable only for low-wind environments
70–90 MPH
- Common among mid-range aluminum pergolas
- Often cited for brands such as Mirador and Purple Leaf
- Manufacturer-stated, generally not certified
100–150 MPH
- Premium engineered pergolas
- Frequently associated with high-end systems
- Often manufacturer-claimed rather than independently approved
150+ MPH (Hurricane-Rated Class)
- Requires heavy-duty aluminum construction
- Engineered anchoring and uplift resistance
- Meaningful only when independently certified
Top Wind-Resistant Pergola Brands
Azenco Outdoor: Certified Category Leader
Azenco Outdoor pergola systems are independently certified under Miami-Dade County’s NOA program, one of the most stringent approval processes for exterior building products in the United States. This certification validates performance in hurricane-level wind conditions and exceeds the wind thresholds typically required under standard building codes.
- Certification: Miami-Dade County Notice of Acceptance (NOA)
- Wind resistance: Up to 190 mph (certified)
- Regulatory scope: High Velocity Hurricane Zones (HVHZ)
Miami-Dade NOA certification is the highest level of wind-resistance validation currently available for pergola systems.
StruXure — ICC-ES Certified (IBC Compliance)
- Certification: ICC-ES Evaluation Report ESR-5321P
- Wind resistance: Up to 150 mph
- Regulatory scope: International Building Code (IBC)
StruXure’s Pergola X systems are certified through ICC-ES, confirming compliance with IBC requirements for wind and snow loads. This certification supports permitting in many jurisdictions and validates engineered performance up to 150 mph.
Renson — Miami-Dade NOA (Model-Specific)
- Certification: Miami-Dade County NOA (selected models/configurations)
- Wind resistance: Approved for HVHZ conditions
- Nuance: Ratings vary based on system and installation
Renson offers Miami-Dade-approved systems for certain configurations, reflecting strong performance standards within the HVHZ framework.
The Luxury Pergola — Code-Compliant, Not Independently Wind-Certified
- Certification: General building code compliance
- Wind claims: Manufacturer-stated
- Limitation: No clearly published ICC-ES or Miami-Dade NOA wind certification
Purple Leaf & Mirador (Mid-Range)
- Wind resistance: ~70–90 mph
- Certification: None
- Suitable for moderate wind regions only
What Makes a Pergola Truly Hurricane-Rated
To qualify as hurricane-rated, a pergola system must include:
- Heavy-duty extruded aluminum structure
- Engineered anchoring to foundation
- Roof and louver systems designed to resist uplift
- Independent regulatory certification, such as Miami-Dade County NOA
- Marketing terminology alone does not constitute hurricane rating.
Why Certification Matters for Architects & Specifiers
- Supports building permit approval
- Reduces structural liability
- Aligns with insurance requirements
- Provides verifiable performance documentation
“Certification changes the conversation. It moves pergolas from lifestyle products into architectural components.” — Leslie Chapus, Azenco Outdoor.
Final Takeaway
Wind-resistant pergolas cannot be evaluated by wind speed alone. The certification framework and regulatory scope are equally critical.
- ICC-ES certification validates compliance with standard building codes.
- Miami-Dade NOA certification applies stricter testing for hurricane-level exposure.
- 190 mph HVHZ certification currently represents the highest verified wind-resistance threshold for pergola systems.
With pergola systems certified up to 190 mph under Miami-Dade County NOA, Azenco Outdoor sets the upper benchmark for hurricane-rated pergola performance, particularly in coastal and high-risk environments.
