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.
Details: Shingles or tiles need to be repaired or replaced • Two-story building • 0 - 10 years old • Asphalt shingles • No, the project is not covered by an insurance claim • Residential

Certified came through for us when our HOA saw that our Soffitt was damaged by birds who decided to take up residence. They busted their butts and took care of the job however small. What impressed me is how professional the crew was, including the owner and the project coordinator. They did not try to upsell when they came out for the estimate. The crew noticed that our neighbors’ roof was one bad windstorm from being blown off (we live in a row house, so roofs matter to all of us). We appreciate the heads up and passed along their info to our neighbors. 10000% using Certified in the future.
Details: Soffit or fascia needs to be repaired or replaced • Three-story building • More than 30 years old • No, the project is not covered by an insurance claim • Residential

Project #2 with Certified - Siding for my home!There arent enough words in the dictionary for me to describe the exceptional customer service and craftsmanship I received from Certified. From a customer service and business perspective, Steve Mitchell and his team are otherworldly. Certified just completed the second project for my house replacing the siding and it literally is a complete makeover of my home and absolutely beautiful! The level of engagement I received from Colin, as the project manager, and Carlos as the onsite manager during the install better than any Ive received from any contractor in 40 years. Certified clearly epitomizes exceptional customer service, exceptional engagement and customer interface and exceptional craftsmanship! Thanks so much Steve, Colin and Carlos!****************************************************************If you're searching for a reliable company to replace your roof, I highly recommend Certified, a Service-Disabled Veteran owned business. From my very first phone call with the owner, Steve Mitchell, I was thoroughly impressed by his professionalism and genuine approach. His guiding principle is do the right thing always, and he truly listened to my concerns, promptly arranging an appointment to move forward.At our meeting, Steve EPITOMIZED EXCEPTIONAL CUSTOMER SERVICE - he listened intently, thoughtfully answered every question, and addressed all my worries. He explained the entire roof replacement process in clear, easy-to-understand terms. When it came to areas where the wood was damaged under the shingles, Certified sent me detailed photos of the damage, then replaced and numbered the plywood so I could see exactly what was done. I received before-and-after photos, and I have to say, if a roof can be beautiful, mine is absolutely stunning and comes with a 50-year warranty!The payment process was straightforward and fair: one-third at contract signing, another third for supplies, and the final third upon completion. Unlike other companies that cut corners or leave customers hanging, Certified delivered on every promise. Im someone who values honesty, and I can confidently say that if you need your roof replaced, CHOOSE CERTIFIED!Colin, Steves project manager, provided outstanding customer service, and the roofing crew led by DeSantis was equally exceptional.Thank you, Steve, for my beautiful new roofIm excited for you to take care of my siding and gutters next. Certified is truly giving my home a complete transformation!
