Pergolas are stunning and versatile outdoor structures that provide the aesthetic appeal, shade, and structural integrity homeowners deserve, but they are vulnerable to high winds. Unsecured structures, including pergolas, can be lifted and loosened by tornadoes and hurricanes, creating dangers and causing devastating damage.
After storms, structural engineers often find that problems start with the failure of these outdoor structures. When pergolas are insufficiently anchored, the aftereffects can be severe. Keeping an aluminum pergola in place prevents serious damage while protecting you and your home, and these windproofing tips will help you accomplish those goals.
Secure and Solidify the Foundation
The foundation is a crucial aspect of outdoor living structures, including pergolas. If not built on a stable, sturdy base, these structures may be more open to wind damage. Whether a pergola is attached to the home or freestanding, a firm foundation helps it endure high winds. These are the best ways to secure an aluminum pergola to its foundation:
- Concrete footings. Concrete is the preferred choice of contractors everywhere, as it provides a secure foundation and prevents lifting and shifting on windy days. To create a concrete footing, dig holes at least three feet into the ground, erect the pergola’s posts, and fill the holes with concrete. Allow the concrete to cure before continuing with construction.
- Heavy-duty anchors. If you can’t pour concrete footings, consider using heavy-duty steel brackets or anchors that secure the pergola’s posts to an underlying slab. Choose hardware rated for outdoor installation and wind resistance.
- Proper orientation. When installing one of our aluminum pergolas, pay close attention to your area’s prevailing winds. Positioning outdoor structures for decreased wind exposure reduces the risk of damage.
Careful placement, pouring concrete footings, and using heavy-duty anchors ensure that your new pergola will withstand the stiffest winds.
Choose the Best Materials and Design
The materials of which pergolas are made determines their wind resistance. Choosing the right materials, including Aluminum, Steel, and pressure-treated wood, makes these structures more resilient without sacrificing their aesthetic appeal.
- Aluminum is a low-maintenance option that’s strong, lightweight, and wind-resistant. If you’re in Florida or another place with a humid climate and a busy storm season, an aluminum pergola will last for decades without decaying or warping.
- Steel offers the perfect combination of strength and aesthetic appeal. Using steel connectors and brackets on an aluminum pergola enhances the structure’s overall stability.
- Pressure-treated wood. If you’re building a wooden pergola, choose pressure-treated wood for durability and resistance to wind, moisture, and heat.
While Steel and pressure-treated wood have their places, Aluminum is the best choice for pergola construction. Furthermore, a pergola’s design plays a key role in its resistance to wind. Our designs minimize horizontal slats and other features that catch the wind, offering an open design that allows air to flow through.

Regular Maintenance
The level of care an outdoor structure receives makes a significant difference in its longevity and durability. Not only does maintenance ensure that pergolas retain their great looks, but it also helps homeowners see issues that may contribute to wind damage. Use these tips to keep your new pergola in peak windproof condition.
- Inspect the pergola regularly. Schedule frequent inspections, especially after severe storms. Look for loose slats, rust on steel fasteners, and other signs of deterioration that may compromise the pergola’s structural integrity.
- Reinforce fasteners and connections. With time, fasteners and joints may loosen due to wear and tear. After the wind has passed, tighten any loose screws and bolts.
- Prevent decay and rot. If you choose a wooden pergola, apply a quality stain or wood sealant regularly to prevent UV and moisture damage that weakens these structures with time. If signs of deterioration are found, address them promptly.
- Trim nearby vegetation. Keep shrubs, bushes, and trees trimmed to reduce the risk of damage during storms. Falling and flying debris can cause serious problems, and proper trimming prevents most issues.
As seasons change, so do the perils of wind damage. In fall, for instance, accumulating leaves add weight to pergola roofs, while winter storms can take their toll. Regularly removing debris, trimming vegetation, tightening loose connections, and inspecting your pergola will minimize the risk of wind damage.
Are Some Pergolas More Resistant to High Winds Than Others?
Pergolas have varying wind ratings, with an average range of 70 to 100 miles per hour. Depending on installation type and quality, the number can be significantly higher or lower. With engineering that allows them to endure winds of 180 miles per hour or more, our pergolas are designed to last a lifetime.
While DIY pergola kits are widely available and useful in areas not prone to high winds, they have plenty of shortcomings. Our team will help you find and install a pergola that’s rated for your area’s winds and climate.

What Makes a Pergola More Wind-Resistant?
Wind resistance is a basic consideration when choosing a new pergola. A pergola’s resistance to wind depends on several factors, such as:
- The durability, quality, thickness, and weight of materials used.
- Installation methods and quality.
- Regular maintenance and inspections for safety, longevity, and stability.
