- Covering San Francisco and the Entire Bay Area
185 Hillside Boulevard, South San Francisco, CA 94080
At 185 Hillside Boulevard in South San Francisco, the homeowner had been dealing with progressive roof wear caused by coastal moisture, marine fog, and seasonal storms common throughout the Bay Area. Ceiling discoloration and minor attic dampness became more noticeable during winter rainfall, indicating that the existing roofing system had reached the end of its service life.
Previous localized repairs temporarily addressed specific leak points, but new problem areas continued to appear. Rather than continue investing in short-term fixes, the homeowner moved forward with a complete roof replacement to restore long-term structural protection.
Royal Roofing CA performed a full tear-off and installed a new architectural asphalt shingle roofing system built for Bay Area weather conditions.

A high-performance synthetic underlayment membrane was installed across the entire roof surface to provide a secondary moisture barrier.
New metal drip edge and flashing components were installed along roof perimeters and around penetrations.
Dimensional asphalt shingles were installed according to manufacturer fastening specifications for wind resistance and long-term durability.
A comprehensive inspection confirmed proper alignment, fastening integrity, and waterproof continuity.
