Fantastic experience working with Columbia Plateau! Zack goes above and beyond to make sure all the details are discussed and has vast industry knowledge to recommend the right product. Mundo and his crew were friendly and did a great job installing the new roof. Thank you!

We are extremely pleased with Columbia Plateau Roofing. The owner was professional and provided multiple options to address our needs, with a thoughtful discussion of the pros and cons of each. The work was done in a timely manner, everyone on the team was professional, and they cleaned up everything, leaving a completely clear site at the end. We were repairing the roof on an addition so there were challenges of tying into the existing roof, plus some features of the original design had caused problems in the past but, where changes to the contract were needed, they were clearly communicated and we were given options for different ways to solve the problems. We would absolutely work with this contractor again and highly recommend them.

I highly recommend working with this roofing company. We had a challenge of finding a contractor that was willing to work out of escrow, strict budget, and had a tight deadline to meet. The work was done quick and was such a stress free process. Roof looks fantastic!

Dan at Columbia Plateau roofing happened to be visiting us during the January 2025 winds that wreaked so much havoc here in Southern California. He was definitely the right man at the right time, because parts of our aluminum roof blew off, and we had no idea where to go to replace our over 30 year uncommon type of roof. He got right to work and found the company that manufactures a similar product. I was able to contact the company and find a roofer in our area that could do the job. Dan really knows his stuff and was quite detailed in what made the roof fail in those 85-100 mph winds. The roofer we contracted with detailed exactly what Dan had said about the cause of the failure. Thanks, Dan, for all the help. We probably would have struggled through several roofers before finding the right one. We are grateful for your expertise.

These people are absolutely amazing!!! From my salesman Mike walking me through everything and explaining/communicating every detail to the crew that Mundo directed. These men were clean, kind and super informative. I would recommend them to anyone.

Took down my gutters, bent them by just dropping them on the ground and when I called to get them put back up, they never did it correctly. I'm 68 and can't climb around on the roof, they still haven't done it. They never put my heat cable back in place, although they said they would during the estimate. One of the workers put his foot through the roof while taking the old roof off and was just going to cover it up. I paid $ 17,000 you'd think that the work would be better. My Bad!!

When I met with Mike he went over all the details regarding the materials they use and why. There were pricing options based on the type of shingles you wanted so it was nice to have choices to fit your budget. The crew worked very hard and finished the job early. They cleaned up very well each day. I did get a lower priced bid but I didn’t feel the quality of materials was as good and they didn’t offer financing options. I am very happy with the way it looks and would highly recommend them! Rebecca Robinson

Dan was quick to come to look at the roof when called upon. He provided expertise and knowledge that comes from being in the industry and continuing learning about the latest products to provide customers. He shared information about the aging roof and advice on longevity and best options for repair.

We appreciate all of the hard work from Zack, Josh, and Jose and all they did to contribute to the success of our new roof. An enormous thank you to Mundo and his crew for all of their amazing work installing our new roof. We appreciate all of you and LOVE our new roof!! We had an unexpected issue with the installation of the underlayment that mother nature brought to our attention. Thankfully the team was amazing, quick to respond, and fixed it before any lasting damage occured. Great customer service!

After reading several reviews and talking to a couple neighbors, we had Zack out to look at the cedar shake roof on our shed. He climbed up and was so careful not to damage the shakes. After a thorough evaluation, he felt all we needed was a metal roof cap. The bid was very fair, so a couple days later Jose was here to do the install. He was very courteous and just as careful while up on the shakes installing the ridge cap. He literally put each old nail in his back pocket so none ended up on the ground for us to step on, and he hauled off all the old material. It was such a pleasure doing business with these two young men!!!

Dan came the day after I called to take measurements and he gave me a bid in a few days. I needed three sections of my garage roof replaced.. He brought a sample of the metal roof to my house make sure it matched some existing roofing. He came sooner than I expected and completed the job in one day. I called several roofing companies and Dan was the only that returned my phone call. Thank you for that.

We are thrilled with our new roof from Columbia Plateau. The house had a problem with condensation caused by inadequate ventilation; Dan and Mike took the time to design and implement the solution, even though it took multiple visits. They were very thorough and professional. The roof looks great!

Fast and efficient work from local company on entire re-roof! Salesman Zack offered practical insights as former repair manager, site-manager Mundo brought decades of hands-on expertise with a fast efficient crew that got the entire roof replaced in about 5 days. Owner Dan was present at job start and offered direct communication with him throughout job. Detailed invoice with job details and photos appreciated!

Would recommend for sure. Honest company who worked to bandaid our roof after a storm versus try to sell us a new roof like the other roofer that stopped by for an estimate. We are planing to replace our roof in the next year or two but wanted to wait as we are doing an addition to our home and wanted a new roof all at the same time. Highly recommend.

Dan, Mike, and the whole team were knowledgeable, reachable, and reliable throughout our entire roof replacement process. From day one, the folks at Columbia Plateau were collaborative about solutions to our roof problems. The advice they offered was comprehensive and realistic, and they helped us to ensure that we would meet the requirements of the product warranty we were aiming for.
They were easy to reach, and willing to go out of their way to provide advice and information upon request. Even if Columbia Plateau isn't the cheapest bid you receive for your project, you will save so much in terms of headaches and setbacks.

The inspection was professional. I was able to tag along and got a good explanation of what the inspector was seeing. I was very comfortable with the recomendations...e.g. what i should do, could do and didnt need to do ...at least yet. The fixes were easily scheduled and completed as described. I would definitely recomend them.

Very professional roofing company. Zack who did the inspection and the bid was outstanding to work with. His knowledge of the roofing profession was impressive. He did more than enough to explain the process of how the company would proceed and do the roofing. The crew was also exemplary in their work and skill. I recommend you choose this roofing company, and you will not regret it.

Called Dan right after a wind storm in November. He came out the very next day to do some repairs on my roof as we were about to have a snow storm the next day. He wanted to ensure no damage inside due to the shingles that had flown off in the wind storm. I couldn't believe he came out the very next day from me calling and did the repairs in the freezing cold. Then first thing when he had an appt open he re-roofed my entire shop in one day with a crew of 3! I appreciate him and his crew; they cleaned up and took all old roof. I highly recommend Columbia Plateau!!

Dan and his crew are top notch. As a local Home Inspector I know I can trust them as an honest referall for my clients. Zach and his team arrived today on time for a multi-family residential inspection and together with myself and a local electrician we provided a full building inspection in less than a full days work. Highly recommended for roof inspections, repairs and full installation work. This is my first referall for Yakima and Kittitas county roofing inquiries hands down.

We needed someone to inspect and seal some roof fasteners following a home inspection. Dan responded to our inquiry, and provided the service we needed the very next day. Dan was prompt, professional, and thorough. We would highly recommend Dan and Columbia Plateau.

Dan and his crew were AWESOME. I had him come out to do an estimate on replacing my shingles. While inspecting the roof for the estimate he noticed some severe damage that need to be corrected. Thanks to Dan's through inspection for the estimate I have had my roof repaired (saving me from far more damage happening in the future) and re-roofed.

Long story short He and his company are efficient and thorough as well as friendly. I will definitely use the again if I need roofing work in the future.

Columbia Plateau, Inc. put a new roof on our 110-year-old barn, in coordination with WA Dept. of Archaeology & Historic Preservation (DAHP) Barn Rehabilitation Project grant program. Despite the challenges of the 2020 Covid-19 regulations and restrictions, they kept us informed on unavoidable delays and complications, and did an excellent job of the highest quality, fast and for a reasonable price. They get my highest recommendation.

I noticed water marks in our bonus room - we have a tile roof and suspected this would be a major repair. Dan came out almost immediately and assured us it was a minor repair. He answered any questions we had and his employees were extremely friendly. They got the job done in a timely manner and at a reasonable cost. I would recommend Columbia Plateau Roofing to any of my friends and family!

Hard rain in the fall revealed a little roof leak on our flat, foam roof! Not a normal thing to content with but Dan was up for the job and handled it quickly and effectively! Thank you!!

The timeline for a roof replacement typically ranges from one to three days, depending on the size and complexity of the roof, weather conditions, and material type. Larger or more intricate roofs may take a bit longer, but we always aim for efficient, timely completion.

3. How to hire a roofing contractor?

To hire a roofing contractor, start by researching local companies with good reviews and proper licensing. Request quotes from multiple contractors, verify their insurance and certifications, and ask for references. Always ensure you get a written contract that outlines the scope of work, timeline, and payment terms.

4. How to check if a roofing company is legit?
+-

Check if a roofing company is legit by verifying their business license, insurance, and local certifications. Look for memberships in professional associations, read customer reviews, and ask for recent project references. A legitimate company will be transparent and provide all documentation upon request.

5. How to choose a roofing company?
+-

When choosing a roofing company, consider their experience, customer reviews, warranty offerings, and quality of materials. Make sure they provide clear communication, detailed estimates, and a solid portfolio of completed projects. Local expertise is also a major advantage for understanding regional roofing needs.

6. How do you know if your roofing contractor is ripping you off?
+-

Warning signs that your roofing contractor might be ripping you off include vague contracts, pressure to pay large upfront deposits, lack of proper documentation, and unexplained price increases. Always ask for itemized estimates and written guarantees, and avoid contractors who avoid answering your questions directly.
