I had a roof leak that wasn’t resolved the first time around, but when Richard and Tim came out for the follow-up, they were fantastic. They carefully inspected the roof, figured out that the issue was caused by nails under the shingles that weren’t sealed properly, and fixed it on the spot—without charging me anything extra.They were professional, transparent, and clearly took pride in doing the job right. I really appreciate their honesty and effort in making sure the problem was properly solved. Richard and Tim went above and beyond, and I highly recommend them for anyone looking for reliable roof repair.

Certified Inc is very good roofing company with great specialists. The specialist thoroughly looked into my roof with various pictures taken and provided to me. He provided great advise associated with the root cause of my home issues. The leakage and wetness happened during heavy rain. I sincerely recommend this company for your roofing needs.

This is at least my 8th job working with Certified Roofing, each on a different house or part thereof. If you're reading this review, then look no further. I recommend you hire them without reservation. Owner Steve Mitchell and everyone under his command are honorable, hard-working, conscientious, responsive, and use their best efforts to do the job properly the first time. As a more exacting customer than most, they've earned my respect and business time and time again. Go get other estimates, then compare the costs. You'll see their prices are always fair, but their workmanship is superior. They do a better job installing products. They clean up better. The employees will look you in the eye and give you honest answers. They are my go-to residential roofing contractor as long as I have a roof over my head. In this last project, they removed old decking material and worked cooperatively with a window and door contractor I chose to install new decking. The attached photos show the attention to detail they paid to my job to do it right. And when I've had other repairs or rare warranty work, they've responded promptly, and addressed the issue completely. They will sell you a quality product that lasts, and they stand behind their work. Certified has earned my trust.

June 28 · Joe Aissi
Experienced and professional team. Josh Artis came out to the house, showed samples and talked me through everything. He was very patient as we struggled to decide on a color. The crew came out early in the morning and were gone by about 2 pm. They didn't leave even one nail that I could find. The roof is beautiful and not nearly as expensive as we anticipated. Great company!
