"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!”

The roofers did a great job, were pleasant and cleaned up after themselves. A little pricier than some but worth it! Stan was my go-to person and kept me updated during the process and was very responsive to any questions I had along the way.

Very professional and organized. They did a great job. A little over priced however they installed roof ventilation which I did not expect.

I have been gathering quotes to get a new roof, i Contacted cobex and the process of making the appointment was quick and easy . Who doesn’t love that ? A mom of 4 that goes to school full time anything that saves time I appreciate . They needed to reschedule for a few hours later which was fine I get things happen. He arrived and we sat down and began to talk. I found it odd he wanted to sit down first before going and double checking his measurements and or for further repairs he let me know he already had the measurements through an areal shot (which the other quotes I was getting did too) and then proceeded to tell me what the price was going to be . I told him I don’t know if he wanted to continue with the process as the other quotes I got were significantly less and he proceeded to pretty much say in other words you get what you pay for. I felt a sense of judgement . The other companies are reputable companies with great reviews . He then said he didn’t want to waste either of our time and left. All that could’ve been done through an email if that’s all that was going to be done and could’ve saved all of our time . A $6000-$8000 price difference but couldn’t even put shoe covers on before stepping in to my families home. Could just be me but a 6-8 thousand dollar difference from multiple other quotes is a bit steep . I really didn’t like that guys attitude making it seem like his company is superior then everyone else’s trying to justify the drastic price difference . To me it sounds like trying to take advantage . Even if they offered to price match I solely wouldn’t go through them just based off this experience . If you read all of this please take the time to get multiple quotes before choosing a company . Do your research . If I could do 2.5 stars I would but since I didn’t actually use the company I rounded up to 3

My husband and I recently moved into a home in Orangevale. During all the recent rains, there was a lot of sand looking material coming off the roofs shingles. We thought for sure we needed a new roof so I contacted the Cobex Roofing company. David Leal came out to our home and asked a lot of questions, then climbed up on our roof and did a thorough inspection with pictures to show me when he was through. He gave us wonderful news that we weren’t expecting and said we had at least five more years of life left in our roof and that he hoped we would contact them in the future when we really needed a new roof. We are so impressed with his honesty (which seems so hard to find these days) and friendliness of David that I will most definitely use them in the future!
