  • I’ve been meaning to leave this review for a while now. Thanks for the friendly reminder Blake. I called Guardian Roofs and spoke with Mona about setting up an appointment for my roof repair in Santa Ana. Blake found the cause of the leak in minutes and was able to give me a quote on the spot. It was $200 less than the first quote I got with a better warranty. They did a great job and no leaks since. Thank you.

  • Excellent work and professionalism. Emiliano and Edwin completed our reroofing, with exceptional skill and work ethics. The roof looks great and I’m very happy for the job well done. Kudos to Mario as well for coordinating everything. He was very professional and sold us on Guardian from the the get go.

  • My home in Pasadena was built in 1896, and after it sustained significant wind-related roof damage following the Eaton Fire back in early January of 2025—a destructive wildfire that impacted nearby Altadena—I knew I needed a roofing company with the expertise to restore and protect a structure of this age. Guardian Roofs & Energy Solutions delivered at every step. Although my home is a historic property, it is not an official contributor to Pasadena’s Historic Preservation Program. That said, Guardian approached the project with the same level of care, respect, and craftsmanship you would expect for a landmark building. They went above and beyond to ensure the structural integrity and historical character of my 125+ year-old home were preserved throughout the entire process. Estimator Justin Sudduth was outstanding—he provided a detailed breakdown of the scope of work, including tear-off and removal of old roofing layers, radiant barrier sheathing, laminated shingle installation, upgraded flashing, new ventilation systems, and more. His communication was clear and proactive, helping me understand each phase of the project and how it would contribute to both performance and longevity. What truly set Guardian apart was their ability to navigate the permitting process and coordinate with city officials, even ensuring appropriate documentation for the home’s age and significance. While my property wasn't subject to formal historic review, their commitment to following best practices in preservation and compliance was evident and deeply appreciated. On site, Bill Scot, the operator, led a highly skilled and professional crew. They were punctual, respectful of the property, and maintained a clean, organized job site throughout. Bill’s oversight and communication ensured the entire project stayed on track and was executed with excellence. Guardian didn’t just repair my roof—they honored the history of my home while strengthening it for the future. Their professionalism, attention to detail, and respect for both modern standards and historical elements make them an exceptional contractor. If you’re seeking a roofing company that can handle complex, age-sensitive projects—especially those involving post-disaster recovery or historic homes—I wholeheartedly recommend Guardian Roofs & Energy Solutions. They’ve earned my trust and gratitude. — Javier Orozco, Pasadena, CA
