If your Orange County tile roof looks perfect from the street and still leaks, the tile is not the problem — the underlayment beneath it is. We lift, re-underlay, and reset your existing tile. Free inspection, written itemized quote.
Orange County is a tile market. Concrete and clay tile is what the county's 1970s, '80s, and '90s tracts were built with — Irvine's villages, Mission Viejo, Rancho Santa Margarita, Lake Forest, Aliso Viejo, Laguna Niguel, San Clemente, San Juan Capistrano, and most of the hillside communities. And tile is genuinely excellent: a concrete tile will do 50 years, a clay tile longer.
The tile is not what keeps water out. The underlayment underneath it does. Tile sheds the bulk of the water and shields the underlayment from UV, but the actual waterproof layer is the felt or synthetic membrane stapled to the deck beneath. On roofs installed before roughly 2000, that layer is 30 lb asphalt-saturated felt, and its working life in Southern California heat is 20 to 25 years.
This is why tile roof failure is so consistently missed. Nothing looks wrong from the street. The tile is intact, the ridge line is straight, the color is fine. Meanwhile the felt underneath has gone brittle, cracked around every fastener penetration, and torn at the valleys — and the first evidence you get is a stain on a bedroom ceiling after the first real atmospheric river of the season.
If your Orange County home was built before 2005 and still has its original underlayment, you are at or past the end of that layer's design life. That is not a sales line; it is the number on the product.
These are two different jobs at two very different prices, and a lot of homeowners are quoted the expensive one when they need the cheap one.
Your existing tile is removed by hand and stacked on site. The deck is inspected and any dry rot or damaged sheathing is replaced. New underlayment — modern synthetic or a heavy modified membrane rather than the old 30 lb felt — goes down, along with new flashing, valley metal, and vent boots. Then your original tile is reset course by course. You keep the roof you have, with a fresh 30–50 year waterproof layer under it. Expect 10–15% tile breakage, which is replaced with matched salvage.
Everything above, plus all-new tile. This is the right call when the existing tile is a discontinued lightweight product that keeps cracking, when breakage on removal would run too high, when the structure cannot carry the load, or when you simply want a different profile or color. It is the more expensive path and, for most Orange County homes with sound concrete tile, it is not necessary.
If only one slope or one valley has failed — common on north-facing slopes and long valleys where debris collects — a section can be lifted, re-underlaid, and reset without touching the rest of the roof. Cheaper, faster, and honest. We will tell you when this is the right answer, because a roof that only needs one slope done does not need a whole-roof invoice.
Either way, plan on 5 to 10 days on site rather than the 1–3 days an asphalt shingle re-roof takes. Every tile is handled twice, by hand.
Tile went on OC roofs in waves, so whole neighborhoods reach the end of their underlayment at the same time. If your street is suddenly full of stacked tile in driveways, this is why.
We will get on the roof, pull a tile, photograph the actual condition of the underlayment beneath it, and tell you honestly whether you are looking at a repair, a partial relay, or a full one. Just your name and number to start.
