We are your trusted roofing contractor in Sacramento, CA

We couldn’t be happier with the results from Cobex. Their team worked seamlessly together, and it was clear that they took their job seriously. From start to finish, every member was fully engaged in the process of replacing our roof. Their commitment and professionalism really stood out, and you could tell they were involved in every detail, wholeheartedly ensuring top-notch quality. The entire experience was smooth, and the craftsmanship is impeccable. We highly recommend them to anyone looking for reliable and efficient roofing services!

We work with Jason and the Cobex crew. They installed our new roof in just two days and it all went as planned. The crew and company were very professional and courteous. The quote was accurate and the project was completed on schedule. I would recommend them any time. Quality materials, People, and Company.

Cobex Construction Group has gone above and beyond! From the beginning they were professional, personable, and thorough. There were no surprises after quoting and they compiled an in depth quote which included pictures. Their pricing is good and are all around good honest people! Thanks Mike!

On time, did the work efficiently, and the job was well done.

We had two sections of flat roof that were 36 years old and definitely needed to be replaced. Cobex came out and recommended an overlay and gave us a quote. They arrived on site at the scheduled date and did an excellent job. Would recommend them.

My insurance company was going to cancel my insurance because of moss and granule loss, I called a number of roofing contractors and received quotes. Cobex was the last company I called and as it turns out should have been the first and last company I called. Junior was very responsive, he came out the next day and met with us surveyed our roof and while on the visit gave us an amazing quote for a roof with a 50 year warranty.His crew was great, they did the tear off in one day and cleaned up and hauled off all debris.The installer showed up next day, completed half the roof in one day returned the next day and completed the roof.They were very neat and cleaned up each day.I highly recommend Cobex to anyone needing to replace their roof.These guys are awesome!

Fast work and uses good materials👍

Friendly staff. The roof was finished in 4 days. I am ready for winter. This company arranged monthly payments!

I have been very satisfied with Cobex Construction. From beginning to end of project it has been a pleasurable experience. The quality of materials used were 2nd to none. The team was very professional, answered all my questions, and kept me advised of what was going throughout the entire process. Very satisfied. Have already recommended Cobex to many of my friends and coworkers.Thank you again, Junior

Cobex Construction Group installed my new roof expertly. From their initial visit to the final installation and clean-up, every detail was carried out in an efficient and thorough manner. I cannot be more pleased the results and highly recommend them.

From start to finish, the Cobex construction group was highly professional and informative . They took all the time needed for me to completely understand the process. I am 74 years of age , and after my 50 year roof warranty has expired, I’ll call for another. Seriously, you definitely want this company to take care of your project. Bob Waterman

Excellent place, very professional every person that worked with me knew their job. I would recommend Cobex to anyone. Happy with my new roof, and notice my mobile home is cooler and use less AC . Sounds much quieter than before. Thanks Cobex

Great company! Our roof is beautiful! The staff are very friendly and went above and beyond to get us our new roof!

Everything was very professional they came out within 1 day and assessed what needed to be done and I got an estimate that same day and within 2 weeks the roof was going on our house and finished after 3 days of work. Very good communication with the people that were working with me I would definitely recommend Cobex to get your roof done thanks.

We wanted to replace the windows in our home. A salesman came out explained the procedure and gave us a quote. After we agreed to the estimate the remainder of the process was smooth and the windows look great!

Quality of work I believe is very good. The actual workers on the job were very courteous and performed their jobs well, although most of the time during the job on site there was no one who spoke English well enough for us to confidently communicate. The person who came to do the estimate, explained the process very well and convinced me their product was worth paying more for. As for the rest of the process, I believe management needs to work on their communication skills with the customer. I often did not know what to expect or when to expect certain milestones. They (management) seemed somewhat disconnected at times. All in all, I am happy with the new roof, but will reserve final judgement on that until we have some winter weather to test it.

They are very well organized and get the job done quick. Also leaves the job clean! I already recommend them to a friend that did her roofing also. Great experience and very good job!

Outstanding experience and awesome job. I worked with Mike and his team at Cobex and they were fantastic. They were able to finish my roof in just over 2 days and I had about 5000sqft and very steep ridges, not an easy task. Roofs are expensive, but I love the 50 year warranty, Not only materials but labor as well., and it's even transferable once. They actually came in the lowest bid but did a fantastic job. Feel very happy and blessed. Thx Mike and Cobex Construction Group Idaho.👊😎👍💯

Did wonderful job just what I want out of work done to my roof ! Would hire them any time or reference for other's to get same quality work ! Thank you so much Robert

We just had our roof replaced with COBEX and I highly recommend this company. They were very professional and did an excellent job! They also did a wonderful job of cleaning up each day. Thomas Drobkov was my main contact. He was very personable and kept me informed every step of the way. Thank you Thomas and the crew for a job well done!

The Cobex team did a great job on our roof replacement. The crew onsite was phenomenal.

Cobex did a very good job on my roof project and was very quick to finish the job.

So glad I found Cobex. The customer service was so excellent! Mike Jiang was great to work with, and he gave us such a great price. I love my new roof.

Everyone was very professional and easy to get along with. Our power bill has gone down and the house seems more comfortable. Excellent installation, tidy. I'll recommend Cobex .

COBEX has provided outstanding service on repairs to my home. I will continue to use them for all my roofing needs.

I would highly recommend you use Cobex to replace your roof! Great communication, quality work and very professional.

Good professional work cleanly done.

**Review Edit 7/2024. I was contacted by the owner of the company who listened, addressed my concerns, received payment and removed the lein that was mistakenly placed on our house. Vazgen is a solid businessman and stands by his word at every step. While we had difficulties with Cobex, the roofing portion of the company was not the issue. I am changing the review to 4 stars because of the poor service from the painting crew.

Very satisfied with the roof project I believe they're the only company in the area that does mobile homes

We were very satisfied with the complete roof replacement done by Cobex. They were able to complete the installation in good time and professionally. It was an amazing experience to work with them. Thank you Cobex

Coved did our roof at a reasonable price and the whole company were great to work with. Thank you Cobex for all your hard work!!

Excellent work! And the workers cleaned up the yard and driveway up afterwards removing all loose nails.I have had neighbors comment on how they like the new color of our roof, White. Which helps keep the house cooler and air conditioner use down.If I would have known….. I would have a new roof installed years ago!

I was having some issues with my leaky roof and contacted Cobex Construction Group to get an estimate for the repairs. They returned my call promptly and showed up on time to give me the estimate. The crew was efficient and professional and finished the work in one day. I've had no problems with the roof since. I would definitely hire Cobex again.

My roof was in very poor shape. COBEX gave me an excellent presentation and bid without pressure. The work was done quickly and the cleanup was done with care. Thanks Cobex!

I called Cobex I needed a new roof on my house and my shed also I wanted to replace my 25 year old A/C unit. Mickey came out and explained everything to us in detail. We also have solar on our roof so we needed that taken off before work could start. Long story short Cobex did everything for us. They came and took the solar off so the tear off crew could do there job. The crew that came out and stripped the old roof did it fast and cleaned up everything. The crew that put on the new roof kept me informed on what was happening and answered all my questions if they didn’t know the answer they had it for me the next day. The A/C guys did a great job as well very helpful. All in all Cobex did a great job for us and did everything we asked in keeping the gate closed so our dogs could go outside and have to worry something might happen to them. I have nothing but good things to say about all the employees at Cobex who helped me in this endeavor. I highly recommend Cobex for your next roof or A/C unit. Dave Allen

This group was knowledgeable, professional, fast and friendly. The quality of their work was outstanding! I recommend them to family, friends, or anyone in need of their specialties. Awesome experience.

We are very happy with our new windows. The installation crew was efficient and tidy! Very little cleanup for them to do. The room is much warmer/ cooler and I love the appearance of the windows and slider. Thanks for a great experience!

Great company overall. Took a little more time due to needing some extra roofing work, but glad they did it. All the inspector found was a handful of roofing nails that got missed on the cleanup. Roof looks great!

I had the pleasure of working with the team at Cobex Roofing, and they were exceptional from start to finish. Every member of the crew was courteous, approachable, and highly knowledgeable, which made the entire process smooth and stress-free. They patiently answered all of our questions and ensured that we were comfortable with every step of the project. Their dedication to clear communication and professionalism created a trusting and positive experience.

Cobex was professional in every aspect. I can tell they have a system dialed down while maintaining genuineness and integrity. The samples were nice to go over in helping make our decision. Once we started they did great updating us on the progress while also addressing any potential challenges. They listened to our list of concerns with care and provided valuable insight on what’s the best course forward. Thomas, I believe he’s one of the sight supervisors, did a great job continually cleaning up the debris around our home along the way which we greatly appreciated.

I had an excellent experience working with Cobex. Vazgen was very informative and professional. I had roof leaks occurring in my property and they were able to mitigate the damages, repair the leaks, and with my roof being 25 years old, they also took care of the removal and installation of my new roof very quickly thereafter. Highly recommend Cobex.
