"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, nine is absolutely stunning and comes with a 50-year warranty! "

When I voiced that I wanted to use another company they told me I signed a contract and they planned to enforce it. If I broke the contract I would have to give them 1/3. I had no choice but to cave. When I pressed on why this wasn't discovered until they started- they had no response. I was stuck and was forced to proceed (or walk away from $7,100). BEWARE!!! 6/25/2025"

"I hired Liberty Windows & Siding for a large exterior renovation project that included siding, windows, doors, gutters, and a portico. I selected Liberty largely based on representations that the work would be performed by in-house crews rather than subcontractors, and that quality workmanship was a priority. Unfortunately, the project did not meet those expectations. The initial installation resulted in widespread workmanship deficiencies, including improper siding installation, flashing issues, trim defects, and other items later documented by both an independent inspector and a manufacturer representative. As a result, Liberty had to remove and reinstall significant portions of the work. While Liberty ultimately undertook remediation, the process was prolonged, difficult to manage, and required extensive homeowner oversight. Remediation details were not consistently documented in writing, work was at times scheduled or attempted without prior coordination, and key quality-control"
