Yakima winters bring repeated freeze-thaw cycles that turn attic heat loss into ice dams along eaves, especially on the older single-story homes common in East Yakima and Terrace Heights. These dams back water under shingles and into attics, damaging insulation and ceilings. We locate the exact heat-loss points with infrared scans, then remove the ice without forcing roof damage, using methods suited to the asphalt and metal roofs prevalent here.
Prevention focuses on sealing attic bypasses and adding targeted ventilation or heat cable runs where the cold air settles along the Yakima River corridor. Homes in Selah and West Valley often have limited soffit intake because of vaulted ceilings or dense tree cover, so we adjust airflow to match each roof's actual pitch and insulation depth rather than using one-size kits.
We also address the secondary leaks that appear once the dam melts, checking flashing at valleys and chimneys that are common failure points on 1970s–1990s Yakima County construction. Every job includes a written report noting any code-level ventilation shortfalls so homeowners can plan future attic work.
Technician insight
In Yakima, the thing that catches most people out with Ice Dam Removal & Prevention is how the river valley cold air pools on the north sides of 1970s–1980s homes in West Valley and Terrace Heights, creating dams even when the rest of the roof looks clear.
Recurring Leak in Terrace Heights Bungalow
A Terrace Heights homeowner called after meltwater stained the living-room ceiling during a January thaw. We found a dam along the north eave caused by poor attic ventilation and a single plumbing stack bypass. After removing the ice and sealing the bypass plus adding targeted heat cable, the roof stayed clear through the remaining winter with no further leaks.
Ice Dam Removal & Prevention Services We Offer
✓Ice Dam Removal
On-site ice removal from eaves and valleys using non-destructive methods that protect shingles during Yakima freeze-thaw events.
✓Heat Cable Installation
Self-regulating cable runs along eaves and valleys to keep melt paths open on north-facing roofs in Selah and Terrace Heights.
✓Attic Heat Loss Sealing
Targeted sealing of bypasses around chimneys, recessed lights and plumbing stacks that drive ice dam formation in older Yakima homes.
✓Gutter and Downspout Clearing
Removal of ice and debris from gutters so meltwater drains away before it refreezes along roof edges in West Valley neighborhoods.
✓Ice Dam Prevention Assessment
Infrared scan and ventilation review that identifies problem areas before the next cold snap hits Downtown Yakima or Union Gap.
Ice Dam Removal & Prevention Cost in Yakima, WA

How it works
- 1
Site Inspection
We examine the roof, attic and gutters from both inside and out, noting heat-loss signs and any existing damage from prior dams.
- 2
Ice Removal
Ice is cleared from eaves and valleys using steam or manual techniques that avoid shingle tearing on frozen Yakima roofs.
- 3
Immediate Leak Check
We inspect for water intrusion into the attic and living space and perform temporary sealing where needed.
- 4
Prevention Work
Heat cable, sealing or ventilation adjustments are installed based on the inspection findings for the specific property.
- 5
Final Walkthrough
Homeowner receives a report with photos and recommendations for ongoing winter maintenance in the Yakima Valley climate.
Pricing
Pricing varies with roof access, ice thickness and whether heat cable or sealing is added.
