"Excellent responsiveness and service. They provided a good solution."

"I would strongly caution anyone considering this roofing company. We had our roof redone in July 2025, and by February we experienced water damage inside our home. After inspection, the issue appeared to be related to poorly installed flashing around a vent. Instead of taking accountability or even seriously investigating the workmanship, the company quickly dismissed the problem and claimed it was caused by an animal, therefore not covered under their warranty. This was disappointing, especially given how soon the issue occurred after a full roof replacement. A reputable company should stand behind their work and be willing to thoroughly assess potential installation issues rather than deflect responsibility. The lack of accountability and unwillingness to help resolve the damage left us dealing with repairs on our own. Based on our experience, I would recommend looking elsewhere if you want a company that stands by the quality of their work and provides reliable customer service."

"The installation went well, the guys were clean and professional."

"Fibers Insulation was extremely professional right from the first call. I chose their service from Angie’s Lust and within minutes Geovany responded. He came out on a Saturday to provide a quote and followed up days later. Members of the company were here at the designated time and did a stellar job! I insulated my garage to add better barrier for my garage to enhance a new AC unit to offset summer heat. Geovany followed up after the installation to ensure all went well. To ensure a better look, taping will be added to keep it looking great. I will recommend them to others in my gated community as I am very pleased with the result. "
