Choosing the Right Pergola Materials for Central Washington's Climate

We recommend looking beyond looks and price point when selecting a home pergola. The Yakima Valley sees a wide range of weather: hot, dry summers, intense UV exposure, sub-freezing winters, heavy snow loads, wide temperature swings and occasional high winds, all of which can be tough on outdoor shelters. Weighing the benefits and drawbacks of each material helps you stay happy with your investment.

Aluminum pergolas

Lightweight yet strong, powder-coated aluminum pergolas won't rust, corrode, warp, rot or crack. They're ideal for deck and balcony installations and work with both modern and traditional home designs. They cost more up front, but aluminum pergolas are a better investment than wood, lasting longer with minimal care. They withstand heavy snow loads and intense summer sun, dissipating heat quickly and keeping their structural integrity across a range of temperatures.

Steel pergolas

Powder-coated steel pergolas offer a modern industrial look. They can span large areas without reinforcement, which makes them a good choice for expansive designs. They resist pests and rot, but rust can form quickly where the finish is scratched or damaged, so repairs need to be prompt. Steel easily withstands snow, but its high thermal mass means it absorbs and holds heat longer than wood or aluminum in hot summer conditions. The weight of some designs may call for stronger footings, additional labor and specialty equipment for installation.

Vinyl pergolas

Popular and cost-effective, vinyl pergolas have a clean, sleek look, though not as refined as metal or wood. Most are prefabricated, which limits size and color customization. Vinyl is low-maintenance and easy to clean, but it can't handle heavy snow loads, softens in extreme heat and becomes more brittle with UV exposure. It is hard to repair and typically needs replacement when damaged.

Wood plastic composite (WPC) pergolas

Affordable, durable and low-maintenance, WPC pergolas blend recycled plastics and wood fibers that resist rot, pests and UV damage. They come in a variety of colors that mimic stained or painted wood, but don't require resealing or repainting. WPC withstands sun and heat but may need metal reinforcement if you live in a snow-prone area. We don't recommend WPC for covering long spans because of sagging, and we suggest investing in higher-quality WPC formulations to prevent early fading and cracking.

Cedar pergolas

Popular and beautiful, cedar pergolas bring warmth and a touch of luxury. The wood contains natural oils that make it pest- and rot-resistant, though it is softer and more susceptible to damage than hardwood. Periodic re-staining or sealing is the trade-off for keeping cedar's rich tones, which can be accentuated with a wide variety of colors. Cedar doesn't absorb and hold heat, so it runs cooler in summer sun. It can carry heavy loads but sags under large snow accumulations. Thicker posts, closer joint spacing and a steeper roof pitch reduce stress on the wood.

Pressure-treated wood pergolas

Budget-friendly and durable, pressure-treated pergolas can handle Central Washington heat and snow loads, but they may twist, shrink or crack as the chemical preservatives dry, and those preservatives can corrode hardware. The green or brown tones of pressure-treated lumber don't have the same appeal as cedar and other natural woods, but with regular staining or painting, a pressure-treated pergola can provide lasting use.

Specialty Pergola Features

Modern pergolas offer more design options than their traditional wooden predecessors, including many ways to improve your outdoor living experience:
