“We are property managers and have used core on numerous jobs over the past two years. They have done repairs, new residential roofs and new commercial flat roof projects. All have been completed with exceptional quality. The staff at Core is great and in constant communication. Our account manager Nathan Christensen goes above and beyond on each job!”

Google Review:

“Nate Christensen at Core Contractors is awesome! He helped my clients get their roof replaced after a big hail storm in the area. They were very professional and helped my parents navigate through the insurance claim process, even fighting to get the same high impact shingle installed at no extra charge. The crew was professional and Nate communicated with my parents through the whole process. I would highly recommend calling Nate at Core Contractors if you need a new roof!”

- Aria C.

BBB & Yelp Review:

“Core Contractors just completed the roof replacement on my house in Golden. Nate Christensen was the rep I dealt with and he was very professional. I received no upfront pressure on whether the replacement was an insurance job or private pay. They quoted me straight up for the work and stuck exactly to their quote. The job looks great! Their crew was courteous, hardworking, and left the job site immaculate. Nate showed up on the first day of the job to be certain the crew was on-site, working, and that everything planned was what we had agreed upon. A crew supervisor (Abraham) was on-site for the entire job. My interactions with the office staff (scheduling and billing) were excellent. Materials remaining after completion of the job were picked up by Abraham and unopened/unused materials were credited back to my final invoice. I received 5 bids for my roof–Core was not the lowest nor were they the highest; however, they were the most professional of all the companies who provided quotes for my job. I highly recommend this company!”

- Tim L.

Yelp Review:

“Core Contractors is THE roofing company you need to call when you need a company you can trust. Nate Christensen and the Core team worked on my in-laws roof recently and did an awesome job, not so much as leaving a nail behind. Nice! They really take a lot of pride in what they do. Do NOT take a chance on the roofing companies that show up right after a hail storm, knocking on your door, telling you they can see that your roof needs repair. They may not even be from Colorado. Work with Core Contractors in Denver, and ask for Nate – he’s the man!”
