How Weather Affects Pole Barn Construction in the Northwest

As a builder who works throughout the Inland Northwest, I’ve learned one thing the hard way: weather matters. Especially when it comes to building pole barns. Whether you're constructing a shop, garage, barndominium, or storage barn, you can't ignore the impact of rain, snow, wind, and temperature swings that are typical in the Spokane region.

At Stimson Contracting, we’ve built through all four seasons and know what it takes to keep your pole barn project on track, no matter what the skies are doing. In this post, I’ll break down how the Northwest climate affects scheduling, materials, site prep, and design—and how we plan around it to deliver strong, durable buildings year-round.

1. Why the Inland Northwest Climate Matters

Spokane and surrounding areas experience distinct seasons, each bringing its own set of construction challenges. From freezing winters to dry, hot summers and everything in between, building here requires planning around weather windows—especially for post-frame construction.

2. Winter Challenges: Snow, Frost, and Freezing Ground

In winter, frozen ground can delay excavation and make post setting nearly impossible without special equipment. Snow accumulation slows down framing and roofing, and icy conditions create safety hazards.

What we do:

• Pre-pour foundation slabs before deep winter hits

• Use frost sleeves or thermal protection where needed

• Secure tarps and heat sources for work during short daylight hours

3. Spring Conditions: Mud and Drainage Issues

Spring may seem like a fresh start, but melting snow and heavy rain can turn job sites into mud pits. Soft soil can make equipment access difficult and delay critical steps like concrete work or grading.

Our solution:

• Improve drainage early in the design

• Elevate building pads for flood prevention

• Use gravel and geo-fabric for stable access routes

4. Summer: Ideal for Speed, But Not Without Hazards

Summer brings long days, warm temps, and ideal conditions for most construction tasks—but it’s not perfect. Heat waves, wildfires, and material expansion are real concerns.

We mitigate by:

• Scheduling early-morning work during heat waves

• Choosing materials that perform well in thermal cycles

• Monitoring fire risk during framing and welding tasks

5. Fall: Tight Windows and Shifting Weather

Fall is a great time to build—if you move fast. As temperatures drop and rain returns, we face:

• Shortening daylight hours

• Unpredictable wind and storm fronts

• Tight schedules to finish exterior work before freeze-up

We recommend starting fall builds no later than early September to stay ahead of weather changes.

6. Moisture and Material Storage

Wet weather can damage untreated materials and delay installation. That’s why we always:

• Store lumber and metal under cover

• Wrap packages in waterproof materials

• Stage deliveries to avoid weather exposure

7. Post Setting and Ground Conditions

Post-frame buildings rely on solid footing. Waterlogged or frozen soil can make it difficult to set posts properly.

We often:

• Use sonotubes or engineered piers in poor soils

• Allow longer curing times for footings in cool temps

• Set posts in gravel when appropriate for drainage

8. Metal Roofing and Wind Considerations

High wind and snow loads are common in the Northwest, so we take extra precautions:

• Engineer trusses for regional wind and snow loads

• Use anti-siphon and fastener-sealed metal roofing systems

• Design for snow slide and ice dam prevention on sloped roofs

9. Weather-Resilient Design Choices

Some clients want a pole barn that can truly handle anything. We recommend:

• Covered porches and overhangs for weather protection

• Gutters and downspouts to manage runoff

• High R-value insulation for energy savings in extreme temps

Designing for the elements gives you comfort, longevity, and peace of mind.

10. Conclusion: Build Smart, Build Seasonally

In the Northwest, weather can’t be ignored—it has to be planned for. Whether you're breaking ground in spring or finishing a project in late fall, the right strategies can make the difference between delays and a smooth build.

At Stimson Contracting, we don’t just build structures—we build solutions tailored to the realities of Spokane’s weather. From foundation to finish, we’ll help you choose the best time to build and the right materials to make your pole barn stand strong through every season.
