A Guide to Steel Pergolas: Can Pergolas Withstand Strong Winds and Rain?

Scroll through Instagram or Pinterest and it’s easy to see why pergolas have become one of the most popular backyard trends in recent years. Whether it provides the framework for outdoor dining, lounging or entertaining, a pergola can turn a deck or patio into a true open-air destination.

But as outdoor spaces become more central to daily life, weatherproofing has to be a larger part of the conversation. Because now more than ever, strong winds, heavy and frequent rains and other types of unpredictable weather events are putting outdoor structures to the test.

So, are pergolas designed to withstand wind and rain? Pergolas made from traditional building materials like wood fall short in outdoor environments… but steel pergolas can provide tested strength and durability even in inclement weather.

The problem with traditional wood pergolas

Here’s the thing. While wood pergolas undoubtedly serve up timeless charm, they are particularly vulnerable to the damaging effects of weathering. Moisture will cause a traditional pergola’s wood components to swell, warp and eventually rot if not maintained properly. Its upkeep, which includes regular sealing, staining and repainting, requires a lot of extra time and money. But even with diligent care, outdoor wooden structures will inevitably deteriorate. Over time, wood pergolas can become a safety concern rather than the heart of an outdoor living space. Making things worse, strong winds can weaken the structure or cause it to collapse, resulting in costly repairs or premature replacement.

Steel pergolas are built to last

Instead, consider the long-term benefits associated with a steel pergola. A strong and durable building material, steel avoids the common pitfalls associated with moisture absorption. Meaning a steel pergola will not deteriorate over time like a wood pergola will. Further preserving the structural integrity of a steel pergola and its appearance, leading outdoor building product manufacturers use a powder-coated finish that provides enhanced corrosion resistance and UV protection. The result is an overhead structure that looks aesthetically beautiful, provides reliable performance in any climate and requires virtually no maintenance.

It’s also worth noting that steel pergolas are noncombustible, ignition- and fire-resistant by nature, which means they can help reduce the vulnerability of a home and any surrounding structures. Prioritizing a fire-safe backyard has never been more important, as devastating wildfires continue to dominate the headlines in many parts of the country.
