Experience with both projects were really great. The communication was very, very quick and efficient. Every single employee we came in contact with was so beyond nice and really cared about the quality of every thing they have done.

"It Was Such an Easy Process from Start to Finish"

When Katie’s roof was leaking, friends recommended she call Cobex. Katie got to see firsthand the Cobex difference: from her first no-obligation estimate to our zero-down financing and personalized project manager who walked her through every step of the process.


“It was so easy communicating with Cobex,” Katie reported. “They answered all our questions, helped us pick out our roof colors, and were super easygoing and really fantastic. I no longer have to worry about a leaking roof!”

Why are you waiting?


The best time to address a roof issue is before it’s too late. Once you see visible signs of leaks and water damage, the damage to your home has already begun. Taking action as soon as you notice signs of a roof issue might save you thousands of dollars in additional home repairs down the road.


No one should have to worry and wait while their roof caves in around them. Our dedicated roofing contractors strive to get your new roof installed in as little as 3-4 weeks. You and your family can usually stay in your home while the roof is replaced, with minimal disruption to your daily activities.


We understand that the only thing more stressful than finding out you need a new roof is worrying about how to pay for it. Choose from one of our attractive finance options and get ready to be surprised at just how affordable your new roof can be.

Client Testimonials

Mike GMike G ★★★★★ Cobex Construction Group recently handled the commercial roofing project for our business, and they were outstanding. From the get-go, they were communicative and transparent about the whole process. Their team arrived punctually every day and showed real expertise and care in their work. What I appreciated the most was how tidy they kept the work area — by the end of the project, there was no trace of construction mess. Our new roof looks sturdy and well-fitted, a testament to their skills. For any business out there needing a roof job, I'd wholeheartedly recommend Cobex. They're reliable and do top-notch work!Cornelius WilkinsCornelius Wilkins ★★★★★ Great service for installing my first floor bay windows. I will be reaching out again in the future for upstairs windows!Del Phoenix-WilcoxDel Phoenix-Wilcox ★★★★☆ Beautiful work.Grady FinchGrady Finch ★★★★★ Joseph KeenanJoseph Keenan ★★★★★ I recently had Cobex install new windows and paint my house. It is from 1937, so it was in need of some love. I met with Chris, the sales rep, who was very helpful and informative to get the job going. The windows were installed faster than the original 2-day install estimate, which was fantastic. The paint, however, did take a little longer than expected. This was only due to them making sure they did the job right, since my older house took some TLC. They were thorough and did not miss one spot. Overall, the job turned out fantastic and I am very pleased with it.Jimmy BanksJimmy Banks ★★★★★ Overall positive experience working with Cobex. Had to wait a little longer than expected, but I think it was worth it. Very detail-oriented group of professionals. I was working with Stan; he is a knowledgeable young man.

Darryl BakerDarryl Baker ★★★★★ Richard is very professional and helpful.Response from the ownerThank you Darryl! Russell SammonsRussell Sammons ★★★☆☆ Sub contractors were used even though I was assured only Cobex employees would do the work.I requested white drip edge, brown was installed.The sub who installed the flashing and painted the vent pipes did a sloppy job.The flashing and vent pipes were painted dark brown, which is not a good match for the amber roof shingles.The flat roof portion was not swept well before installing the TPO material. Several areas show debris bulging up from underneath.I have brought these issues to the attention of Cobex’ production supervisor. Waiting for their response and resolution plan.Brandy ReissigBrandy Reissig ★★★★★ The process from sales to completion went very smooth. Great customer service!Response from the ownerThanks Brandy!

Brandon LBrandon L ★★★☆☆ My experience with Cobex is a mixed one. Intial introductions went well, the representative from Cobex that came out to perform the inspection and estimate was nice and professional.Once the job was agreed upon the work was suppose to start within 6-8 weeks. During that period I felt Cobex dropped the ball in regards to updating me when the job my begin since the work was delayed due to weather. Not their fault but again communication is needed.Once the work began the everything seemed to be going smoothly until they removed my entire roof before letting me know there would be an additional $9,000 dollars in work needed due to missed items on the inspection/estimate. After going back and forth that $9,000 turned into $3,500 and we were able to continue.Once again everything was going smooth until coming home to see a cracked window in my kitchen. After speaking with the representative from Cobex they agreed to take care of the window they damaged.After everything was complete the new roof on my house does look amazing.Overall the experience was a little tiresome dealing with the back and forth but the quality of work was great. They definitely do quality work, just make sure they do a proper inspection/estimate before work begins.Response from the ownerHi Brandon. We understand your frustration. We should have done a better job of communicating with you and updating you more often on the timeline. Sorry that you did not recieve a 5-star experiance from end to end. We appreciate you working with us to resolve the issues that came up. Thank you.

He is very professional and is a good representative in deportment and assuring that the company will do its best to get the job done timely and by company paid employees, not farming it out to subcontractors.Give him a call, he will take car of your roofing needs expediently.Nicole CarlsonResponse from the ownerThank you Nicole, we appreciate the great feedback.
