Introduction

When temperatures start to dip in Spokane and snow begins to make its return, roofs across the Inland Northwest face their toughest season of the year. From heavy snow loads and freeze-thaw cycles to ice dams and hidden leaks, winter weather puts tremendous pressure on both commercial and residential roofs.

That’s why a pre-winter roof inspection is one of the smartest maintenance steps property owners can take. It prevents small issues from turning into major winter emergencies and helps protect your building’s structure, insulation, and interior spaces.

In this guide, we’ll walk through a comprehensive roof inspection checklist tailored for Spokane’s climate — helping homeowners and facility managers prepare their roofs for the cold months ahead.

Why Pre-Winter Roof Inspections Matter in Spokane

Spokane’s winters are unpredictable. Temperatures can swing dramatically, snow accumulates fast, and ice buildup is common. Those fluctuations take a toll on roofing systems, especially older or neglected ones.

Key Reasons to Inspect Before Winter

• Prevent Leaks: Snow and ice melt can seep into cracks or gaps, causing damage.

• Avoid Ice Dams: Clogged gutters and poor insulation lead to ice dam formation.

• Protect Structural Integrity: Heavy snow adds weight that stresses trusses and decking.

• Save on Heating Costs: Tight seals and proper insulation improve energy efficiency.

• Extend Roof Lifespan: Routine maintenance catches problems early, reducing costly repairs.

By scheduling an inspection before the first frost, you can address vulnerabilities — and ensure your roof performs reliably all season long.

Pre-Winter Roof Inspection Checklist

A thorough inspection should cover every component of your roofing system, from shingles and seams to flashing and gutters.

Here’s a step-by-step checklist for both commercial and residential roofs:

1. Examine Roof Surface Condition

Start by inspecting the roof membrane or shingle surface. Look for:

• Cracked, curling, or missing shingles (on residential roofs)

• Blisters, punctures, or seam separations (on flat commercial roofs)

• Standing water or ponding areas

• Excessive granule loss, which indicates aging asphalt shingles

If you notice widespread wear or damage, consider applying a protective roof coating or scheduling minor repairs before Spokane’s freeze-thaw cycles worsen them.

2. Inspect Flashing and Sealants

Flashing is one of the most common sources of winter leaks. Check around:

• Chimneys

• Skylights

• Vents and HVAC units

• Roof edges and parapet walls

Ensure flashing is securely fastened and sealed. Reapply or replace worn sealants to prevent water intrusion during snowmelt.

3. Clear and Test Drainage Systems

Proper drainage is essential when Spokane’s snowfall melts rapidly. Clean out:

• Gutters and downspouts

• Internal roof drains

• Scuppers and overflow systems

Test for blockages by running water through them. If water doesn’t drain freely, schedule a cleaning or repair to prevent ice buildup and gutter damage.

4. Inspect Attic and Insulation

A roof’s condition isn’t just what you see outside — attic insulation and ventilation play a big role.

• Check for signs of water stains or mold growth.

• Ensure insulation is evenly distributed and dry.

• Confirm ventilation pathways (soffit and ridge vents) are open to prevent condensation and ice dams.

Poor attic ventilation is one of Spokane’s most common winter roofing issues. It traps heat that melts rooftop snow unevenly, leading to damaging ice dams.

5. Evaluate Roof Penetrations

Every penetration (like pipes, vents, and equipment mounts) should be watertight. Look for cracked boots, separated seams, or deteriorated seals — all of which allow leaks when snow starts melting.

6. Check Perimeter and Fascia Boards

Inspect eaves, fascia boards, and roof edges for rot, sagging, or pest damage. These areas often deteriorate first due to trapped moisture. Reinforcing them now prevents costly soffit or gutter repairs later.

7. Assess Structural Components (Commercial Roofs)

For commercial buildings, ensure roof decks and support systems can handle winter’s load.

• Verify that snow load ratings meet local code.

• Look for dips or soft spots in the decking.

• Schedule professional snow removal plans if necessary.

Preparing for Winter: Additional Preventive Steps

Beyond inspection, a few proactive maintenance tasks can dramatically reduce winter roof stress:

• Apply roof coatings or sealants to add waterproof protection.

• Trim overhanging trees to prevent debris buildup and falling branches.

• Install snow guards on metal roofs to control snow slides.

• Schedule professional maintenance to handle minor issues before they grow.

Even small repairs — like sealing a joint or tightening flashing — can save thousands in water damage once Spokane’s winter storms hit.

Frequently Asked Questions

How often should I inspect my roof in Spokane?
At least twice a year — once in the fall (pre-winter) and again in the spring after snowmelt.

Can I inspect my roof myself?
You can perform a visual check from the ground or attic, but it’s best to hire a licensed roofing professional for a full inspection.

What’s the average cost of a professional roof inspection?
In Spokane, inspections typically range from $150 to $400, depending on roof size and complexity. Some contractors waive this fee if you move forward with repairs or maintenance.

What’s the biggest winter roofing issue in Spokane?
Ice dams and leaks caused by poor ventilation and clogged gutters are the most common.

How can I prevent snow load damage?
Clear snow gradually and evenly, avoid using sharp tools, and consider hiring a roofing company that offers safe snow removal services.

Conclusion

A pre-winter roof inspection is one of the best investments Spokane property owners can make. It prevents costly leaks, improves insulation efficiency, and ensures your building stays safe, warm, and dry through the harshest months of the year.

Whether you manage a commercial facility or own a residential property, taking time now to evaluate your roof can prevent major headaches — and protect one of your most valuable assets.

Schedule your inspection before the next snowfall, and let professional roofers ensure your system is ready for another Spokane winter.
