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

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
