The text came at midnight: "Workshop is flooding. Meet you there."

February 2019. Tacoma buried under 14 inches of wet snow, then freezing rain, then rapid warming. Tom's auto repair shop—built by a "experienced" contractor just three years earlier—was failing catastrophically. Water poured through the roof. Ice dams sent cascades down interior walls. The weight of wet snow had already buckled two garage doors.

By morning, Tom had $45,000 in water damage and couldn't open for business.

Meanwhile, across town, Mike Torres ran his auto repair shop without interruption. Same storm. Same snow load. Same freezing rain. But his ProBuilt shop stayed dry, warm, and operational. While competitors closed, Mike captured an extra $8,000 in emergency repair business that week.

The difference? Engineering specifically for Tacoma's unique winter challenges.

The Winter Storm That Changed Everything

February 2019: Tacoma's Reality Check

Most years, Tacoma winters are mild. Rain, not snow. That's what makes the occasional severe event so devastating—buildings aren't ready. The 2019 storm exposed every shortcut, every generic design, every contractor who didn't understand our specific challenges.

Storm timeline:

Day 1-2: 14 inches of heavy, wet snow (40 lbs/sq ft load)
Day 3: Freezing rain creates ice layer on snow
Day 4: Rapid warming to 45°F
Day 5: 2 inches of rain on melting snow

This combination—weight, ice damming, rapid melt—destroyed hundreds of buildings. But not ours.

The Failure Pattern

We inspected damaged buildings after the storm. The pattern was clear:

Roofs designed for 25 PSF (code minimum) failed at 35-40 PSF
Standard ventilation trapped heat, accelerating snow melt and ice dams
Generic connections couldn't handle wet snow's dynamic loads
Drainage systems overwhelmed by rapid melt plus rain

Every failure was preventable. With proper engineering.

Mike's Shop: Built for the Storm Nobody Expects

The Original Challenge (2018)

Mike Torres had lost a previous building to the 2012 ice storm. When he came to us in 2018, his requirements were clear: "Build me something that can handle the worst storm in 50 years. I can't afford to close again."

His Lakewood site presented challenges:

North-facing slope (slower snow melt, more accumulation)
Wind exposure from the west
Clay soil requiring special drainage
Previous building's foundation still failing from poor drainage

Our Engineering Response

We didn't just meet code. We engineered for reality:

Snow Load Design:

35 PSF uniform load (40% above code)
50 PSF drift load calculations
Unbalanced load scenarios for wind-driven accumulation
Connection details rated for 50% overload

Ventilation Strategy:

Cold roof design prevents heat transfer
Continuous ridge and soffit vents
1:150 vent ratio (double typical)
Baffles preventing wind-driven snow infiltration

Drainage Systems:

6-inch gutters (vs. standard 5-inch)
Oversized downspouts with heating cables
Underground drainage to storm system
Surface grading directing melt away from building

Storm Performance Report

During the 2019 event:

Snow load reached 38 PSF—our design handled it easily
Zero ice dams despite freeze-thaw cycles
Drainage system processed 1,200 gallons/hour during peak melt
Interior stayed dry and comfortable throughout
Business never closed, captured competitor's customers

Investment in upgrades: $8,000. Storm damage prevented: $45,000+. Additional revenue from staying open: $8,000. ROI: Immediate.

Why Tacoma Winters Are Uniquely Challenging

The Convergence Zone Effect

Tacoma sits in a unique position where multiple weather patterns collide:

Marine air from Puget Sound: Usually warm and wet
Arctic outflow from Fraser Valley: Occasional severe cold
Cascade mountain effects: Enhance precipitation
Olympic rain shadow: Creates variable conditions

Result: Rapid temperature swings that create ice dams, freeze-thaw damage, and structural stress.

The Wet Snow Problem

Tacoma snow isn't like Colorado powder:

Typical snow: 10-15 lbs/cubic foot
Tacoma wet snow: 20-30 lbs/cubic foot
With ice layer: 40+ lbs/cubic foot

Generic building designs assume light snow. Ours don't.

The 48-Hour Swing

Tacoma can go from 20°F to 50°F in 48 hours. This creates:

Rapid snow melt overwhelming drainage
Ice dam formation and release
Thermal expansion/contraction stress
Condensation inside poorly designed buildings

Our designs anticipate these swings.

Engineering That Makes the Difference

Structural Upgrades Worth Every Penny

Foundation Design:

Deeper footings below frost line (36" minimum)
Drainage rock preventing frost heave
Perimeter drains handling snowmelt
Slope-adjusted pier depths

Frame Specifications:

6x6 posts minimum (vs. standard 4x6)
Engineered connections rated for dynamic loads
Hurricane ties throughout (yes, in Tacoma)
Doubled headers at all openings

Roof System:

5:12 minimum pitch for snow shedding
Ice and water shield at all edges
Reinforced attachment points
Snow guards preventing avalanche slides

The Ventilation Secret

Poor ventilation causes more winter failures than snow load:

Standard Approach (Fails):

Minimal vents "to keep heat in"
Warm roof melts bottom snow layer
Water runs to cold edge, freezes
Ice dam forces water inside

Our Approach (Works):

Maximum ventilation keeps roof cold
Snow stays frozen, doesn't create ice dams
Any melt water exits properly
Building stays dry regardless of conditions

Material Selection Matters

Not all materials handle Tacoma winters:

Roofing:

26-gauge minimum steel (vs. 29-gauge standard)
Concealed fastener systems preventing ice backup
Kynar coating resisting UV during winter sun
Thermal movement joints preventing buckling

Insulation Strategy:

R-30 minimum roof insulation
Continuous vapor barriers
Thermal breaks preventing condensation
Ventilation channels above insulation

Your Winter Preparation Checklist

If You're Building New

Demand calculations for actual snow loads, not minimums
Verify ventilation design prevents ice dams
Ensure drainage handles rapid snowmelt
Include thermal breaks preventing condensation
Plan for maintenance access during winter

If You Have an Existing Building

Inspect before winter: September/October ideal
Clear gutters and drains: Test with hose
Check ventilation: Should see daylight through soffits
Monitor snow loads: Have removal plan ready
Document everything: Photos help with insurance

Recent Client Feedback

"The 2019 storm destroyed my neighbor's shop. Mine didn't even creak. The extra engineering was worth every penny."

- James Chen, Tacoma business owner

"Other contractors said I was overbuilding. After seeing storm damage around town, I'm glad ProBuilt talked me into proper engineering."

- Sarah Williams, Puyallup

"My ProBuilt garage is 12 years old. Still performs perfectly every winter. Can't say that about my house roof."

- Robert Anderson, Federal Way

Don't Wait for the Next Storm

Tacoma's mild winters make people complacent. Then a 2019-type event hits, and unprepared buildings fail catastrophically. Insurance might cover damage, but it won't recover lost business, damaged equipment, or your reputation.

Smart builders prepare for the worst while hoping for the best. That's not pessimism—it's proven wisdom from 37 years of Pacific Northwest construction.
