615 Hillcrest Boulevard, Millbrae, CA 94030
At 615 Hillcrest Boulevard in Millbrae, the homeowner had a concrete tile roof that appeared structurally sound from the exterior. The tiles were intact and visually consistent with the neighborhood’s architectural style. However, during heavy winter rainfall, water intrusion began developing near a valley transition.
After a detailed inspection, it became clear that the problem was not the surface tiles. The underlying waterproof underlayment had deteriorated due to age and prolonged exposure to coastal moisture.
Instead of replacing the entire tile roof, the homeowner chose a tile roof reinstall. This process allowed us to remove the existing tiles, replace the worn underlayment and flashing components, and reinstall the original tiles — restoring waterproof protection while preserving the home’s original design.
