Concrete and clay tile can easily last 75–100 years. The underlayment beneath — 30-lb felt or synthetic — lasts 20–35. When we get called out to a Rancho Santa Fe or La Jolla estate with leaks and 25-year-old tile, the honest recommendation nine times out of ten is not a full tear-off. It's lift and relay.
What lift & relay actually is
We carefully remove every tile, stage them on the property, strip the failed underlayment and battens, inspect and repair the decking, install new synthetic underlayment (Polyglass Elastoflex or similar) and pressure-treated battens, and re-lay your original tile with new metal flashing, ridge caps, and fasteners. The visible roof looks identical when we're done.
When lift & relay is the right call
- Tile is intact — under 10–15% breakage.
- Roof is 20–35 years old and leaking, or underlayment is visibly torn during inspection.
- You want to preserve original architectural character (Covenant homes, historic Mission Hills).
- Concrete tile discontinued or clay tile matched from a small production run.
When it's the wrong call
- Tile itself is spalling, delaminating, or over 40% broken.
- Decking is rotted beyond spot repair.
- Homeowner wants a different color or profile.
Real cost comparison
For a typical 2,800 sq ft Rancho Santa Fe home, a full tile tear-off and replacement runs $48,000–$70,000. Lift & relay on the same home is typically $26,000–$38,000 — with a new 30-year underlayment warranty. That's a $22,000+ savings on the same waterproof outcome.

Frequently Asked Questions
What is a tile lift and relay?
We carefully remove your existing tile, replace the failed underlayment and battens beneath it, then relay the same tile back onto the new waterproof system. Broken pieces are replaced. It restores 25–30 years of leak protection at 50–65% of full replacement cost.
How long does a tile roof underlayment last in San Diego?
Original organic felt underlayment used from the 1980s–2000s lasts 20–30 years. Modern synthetic underlayment lasts 40+ years. When your tile roof is 25+ years old and leaks are appearing, it's the underlayment failing — not the tile.
Can any tile roof be lifted and relayed?
Almost all can. Concrete and clay tile in good structural condition — even 40+ year old roofs — are excellent candidates. If more than 20% of tiles are cracked or the profile is discontinued, full replacement often makes more sense.
How much does lift and relay cost in San Diego?
Typically $10–$16 per sq ft — roughly half the cost of full tile replacement. A 2,400 sq ft home runs $24,000–$38,000 depending on tile condition, pitch, and access.
