Columbia Plateau Roofing · Union Gap & Ellensburg
Locally owned and roofing Yakima and Kittitas counties for more than 25 years: shingle, metal, tile, flat and commercial roofs, with a free inspection before anyone quotes you a number.
Gust Guard · Glacier Guard
Shingle blow-offs are the Ellensburg roof problem, and most manufacturer wind warranties stop at 15 years. Gust Guard is Columbia Plateau's own installation system: Sure Grip fasteners, 50% more than the industry standard, and a lifetime warranty against blow-offs. On metal roofs, Glacier Guard holds back sliding snow and ice.
CertainTeed ShingleMaster Premier and Malarkey Emerald Premium, which is what lets them write the longest manufacturer-backed labor warranties in the area.
Custom flashing is bent in house, so valleys, chimneys and copper details fit the roof instead of the catalog.
Yakima Herald-Republic Reader's Choice 2023, Best of Kittitas County twice, and Business Times best roofer seven years in a row.
What the crew does
Every Columbia Plateau job is read from the attic up: decking, flashing, the fasteners that hold in the wind, the surface you see from the street, and what the winter piles on top. Each layer has a crew that knows it.
Every layer at once
Full tear-off and replacement on homes across Yakima and Kittitas counties. Catch-All netting protects siding, windows and beds, the Equipter hauls old roofing without rutting the yard, and a project manager stays on the job until it is cleaned up.
How a replacement runs
Surface layer
Standing-seam steel and copper, with custom flashing bent in their own small fabrication shop. Glacier Guard keeps sliding snow and ice from tearing at gutters and lower roofs.
Metal roofing
Fastening and flashing
Blown-off shingles, failed flashing, leaks and storm damage, found and fixed. When a barn owner's discontinued three-tab shingles were sold out everywhere, the crew still had bundles to match the repair.
Roof repair
Membrane and metal
Businesses, churches and apartment buildings: metal, TPO and PVC systems with GAF and Duro-Last credentials, run on schedule so the building stays open while the roof goes on.
Commercial roofing
Snow and ice
Ice dams come off with a low-pressure steamer, not hatchets or salt, before meltwater backs up under the shingles. Then they tell you why the dam formed and how to stop the next one.
Ice dam removal
Attic up
Measurements, drone photos and a look inside the attic for ventilation, insulation, leaks and mold, then a clear proposal the same day. No obligation, and the photos are yours.

They cleaned up the area every day and made sure the building was accessible for Sunday services at the end of every work week. This was a tough building to roof and the crew did a wonderful job!
Wind-damaged barn, Ellensburg
“No problem, we have a few three-tab shingles bundles to make your repairs.” Their attitude and desire to help are exactly the kind of contractor I like doing business with!
Complete new roof
The job was a complete new roof. It was done in less than a week. Afterward the estimator, Zach, returned for a thorough inspection including vent inspections in the attic.
Northgate shingles + Gust Guard
We are very happy with the 50yr St Gobain CertainTeed Northgate Climate Flex shingles, the Gust Guard system, and the 30yr workmanship warranties, the meticulous job Jose’s crew did and the cleanup.
How every Columbia Plateau project runs, from the first ladder to the last magnet sweep.
They measure the roof, fly a drone for detailed photos and go into the attic to spot problems the shingles hide.
You get every option explained: materials, the Most Trusted, Trusted and Basic roof systems, and each step of the job.
A clear written proposal with the project steps, pricing and terms. Financing through Profund if it helps.
Catch-All protection goes up, the crew cleans up every day, and nothing is left in the yard when they drive away.
