"I recently had my roof replaced by Home Genius, and I couldn?t be happier with the entire experience. From start to finish, everything was handled professionally and efficiently. The Sales Rep, Zach, was knowledgeable, patient, and took the time to explain the process clearly so I felt confident moving forward. My project manager, Dakota, was outstanding. He kept me informed every step of the way and made sure everything stayed on schedule. His crew was punctual, hardworking, and incredibly respectful of my property. They completed the entire roof in just one day, which was impressive, and the quality of the workmanship was fantastic. The attention to detail really shows. The cleanup was thorough, and they made sure everything looked better than when they arrived. It?s clear this company takes pride in what they do.

Liberty is a 2nd generation family owned and operated company. Offering the best in Roofing, Windows, Siding, Decks, Doors and Gutter material and installation. Financing Available with many options, Licensed, Insured and Certified we offer Free in-home consultations. Additional DBA - Liberty Commercial Roofing. Up to 18 months no interest, no payment financing available; please call for details!

"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"
