Roof Problems in Rancho San Diego, CA.

Yes. Most of Rancho San Diego sits in a SDG&E high-risk fire zone, which means Class A fire-rated roof assemblies and ember-resistant ventilation are required for replacement projects. Insurance carriers in this area require documentation of compliance for renewal. We provide written assembly documentation and coordinate fire-zone compliance with your insurance agent.

This is the most common scenario in Rancho San Diego right now. The tile itself is essentially a sun shield and water diverter, but the underlayment beneath it is what actually keeps water out. Original 1980s-90s underlayment in this area is typically failed or near-failed now. When the underlayment fails, water reaches the deck even though the tile looks intact, and you see ceiling staining as the moisture works through over time. The fix is tile lift-and-relay rather than full tile replacement.
