Metal roofs in Yakima County expand and contract sharply with the valley's hot dry summers and freezing winters. This movement loosens screws and opens seams on older stock common in Downtown Yakima and Terrace Heights. We focus on restoring the original panel integrity rather than layering sealant that fails after one more freeze-thaw cycle.
In neighborhoods like West Valley and East Yakima, many metal roofs date to the 1970s and 1980s and sit on steeper pitches near the Yakima River where wind-driven rain finds every gap. We check ridge caps, step flashing and eave edges first because those spots collect the most debris and hold moisture longest during cold months.
Selah and Union Gap properties often have corrugated panels over older sheathing that has begun to sag. When leaks appear we verify fastener placement against the original corrugation pattern and replace only the damaged sections so the remaining roof continues to perform without new stress points.
Sunnyside-area farms and outbuildings frequently use exposed-fastener metal that vibrates in high winds. Our repairs include torque-checking every screw within a ten-foot radius of the leak and installing neoprene washers rated for the temperature swings recorded at the Yakima Valley Museum weather station.
Technician insight
In Yakima the thing that catches most people out with Metal Roof Leak Repair is the way our cold winters and hot summers keep working the same screws year after year on roofs in Downtown Yakima and Terrace Heights. Homeowners often try to stop the leak with a tube of caulk that cracks the first time temperatures drop below freezing.
West Valley corrugated leak after first freeze
Water appeared in the kitchen ceiling of a 1980s home in West Valley after the first hard freeze. We found three stripped screws along the eave where ice had pushed the panel upward. We replaced the screws with new sealed fasteners, reset the eave trim, and ran a water test that confirmed no further entry.

How it works
- 1
On-Site Inspection
We climb the roof and map every seam, fastener and flashing within ten feet of the reported leak while noting pitch and panel type.
- 2
Leak Source Confirmation
We use a hose test from the ridge downward to watch exactly where water enters, avoiding guesswork on older corrugated sections.
- 3
Targeted Repair
We replace or re-seal only the failed components using materials matched to the existing panel profile and Yakima temperature range.
- 4
Final Water Test
After repairs we run a second controlled water test and inspect the attic for any remaining moisture before leaving the site.

Upfront quotes after inspection; price depends on roof access, panel type and extent of damage.
