Tile roofing is the signature look of San Diego architecture. Spanish Colonial, Mediterranean, Mission Revival, and contemporary custom builds in La Jolla, Del Mar, Rancho Santa Fe, Rancho Bernardo, Fairbanks Ranch, and Scripps Ranch all rely heavily on clay and concrete tile. Done right, a tile roof lasts 50-100 years. Done wrong — with shortcut underlayment, cheap fasteners, or poor ridge mortar — it fails in 15-20. Peak Builders & Roofers has installed, repaired, and lifted-and-relayed more tile in San Diego County than most. This page covers tile types, the lift-and-relay specialty that saves you 40-60%, costs, and when tile is (and isn't) the right choice.
Tile Types San Diego Uses
Concrete S-Tile (most common)
The "Spanish S" profile that's synonymous with SD tract development from the 1980s-2000s. Durable, affordable, widely available.
- Service life: 50+ years the tile itself; underlayment replaces every 20-30 years
Concrete Flat Tile
Low-profile concrete tile that mimics slate or shingle aesthetic. Popular in contemporary builds.
- Service life: 50+ years
Clay Tile (S-profile / Barrel / Mission)
Traditional Spanish clay, handmade or manufactured. Premium product used in La Jolla, Del Mar, Rancho Santa Fe, and high-end Mediterranean builds.
- Service life: 75-100 years
- Key consideration: authentic clay needs proper batten system + weight considerations (20+ psf dead load vs 10 psf for standard shingle)
Composite / Synthetic Tile
Polymer-based tile that mimics clay or slate. Lighter than real tile, often warranted 50 years.
- Service life: 40-50 years
The Lift-and-Relay Specialty (Save 40-60%)
Here's the most important thing to understand about tile roofs: the tile itself doesn't fail. The underlayment beneath does.
On a 1990s Poway or Rancho Bernardo concrete tile roof, the ceramic or composite tile will outlive three owners. But the asphalt-saturated felt or synthetic underlayment has a 20-30 year service life. When underlayment fails, water migrates under the tiles and leaks at penetrations.
The solution: Tile Lift-and-Relay.
- We number + photograph every tile
- Carefully remove tiles (keeping them organized by location)
- Strip old underlayment to the deck
- Install new 40-lb felt OR synthetic underlayment (we use Titanium PSU or CertainTeed Diamond Deck)
- Replace broken/cracked tiles (typically 5-10% needs replacement) — we source-match or use from your stock
- Re-lay tiles in original position, new foam adhesive or fasteners
- New ridge mortar + boot flashings
When lift-and-relay makes sense:
- Tile is in 90%+ good condition (minor breakage only)
- Underlayment is 20-30+ years old
- You like the existing tile aesthetic
- Budget is a factor
When full replacement makes sense:
- Significant tile breakage (>20% broken)
- Upgrading to different tile type (concrete to clay, for example)
- Structural deck issues discovered
- Adding solar that requires denser tile layout
San Diego Tile-Roofing Quirks
Coastal Fasteners
Within 4 miles of the coast (La Jolla, Del Mar, Carlsbad, Encinitas, Oceanside), galvanized steel nails corrode in 7-10 years and tile migrates. We spec stainless or copper fasteners on all coastal installs. Non-negotiable.
Wildfire Zone
Tile itself is Class A fire-rated. But the assembly matters — the deck + underlayment + tile must TOGETHER meet Class A. On VHFHSZ properties, we also install ember-resistant vents + bird-stopping at tile ends.
