Our story

About Guardian Roofing

Guardian Roofing is a family-owned, licensed roofing company started in 2019 by John, who was born and raised in Sonoma County and brings more than a decade of roofing experience to every job. He runs Guardian alongside his wife Heather, who keeps the office responsive and the schedule on track.

What sets Guardian apart is that John isn’t just the owner — he’s the project manager on site for the entirety of each install, demanding quality and clear communication from estimate to cleanup. As a GAF-certified contractor (CSLB #1062288), the team handles everything from CertainTeed Landmark shingle re-roofs to metal and heat-welded commercial TPO, for homes and businesses across Sonoma, Napa and Marin.
