What a Tile Re-Felt Costs in Southern California — Step by Step
What moves the number on a tile roof in Ventura Boulevard corridor, and what a quote should already include.
Price is the first thing anybody wants and the last thing most contractors will commit to. For tile roofing in Southern California the working figure is $8 to $14 a square foot installed, and the rest of this explains what moves it — because the same roof can differ by half again depending on things you can check yourself before anyone quotes.
What you are actually paying for
Clay and concrete tile will outlast the person who buys it. What fails is the felt underneath. That is the single most useful thing to understand about a tile roof, because it explains why a roof that looks perfect from the street can be leaking, and why the quote is for labour and underlayment rather than for new tile.
Where quotes diverge
Thirty-pound felt baking under clay for twenty years becomes brittle enough to crumble between finger and thumb. Once it has gone, the tile is decoration: it sheds the bulk of the water, the underlayment handles what gets past, and with nothing underneath the next storm finds the deck. A re-felt lifts and stacks the existing tile, strips the old underlayment, repairs whatever the deck needs, lays new membrane and relays the same tile. Modern synthetic underlayments last considerably longer than the felt they replace, which is why the second re-felt tends to be further away than the first.
How Southern California changes the figure
On hillside properties, seismic movement works tiles loose along hips and ridges, where the mortar bed cracks and lets water track sideways under the courses rather than down over them. In the older neighbourhoods the harder problem is matching a discontinued profile — an original barrel tile from the nineteen-twenties has no modern equivalent, and sourcing salvage is the single most common cause of delay on a tile job in this city.
What we look at before quoting
- Underlayment condition at eave, valley and every penetration
- Cracked, slipped or previously walked-on field tiles
- Mortar along hips and ridges, and whether it has parted from the tile
- Sherman Oaks metal for corrosion and for debris packed under the courses
- Batten condition where the tiles are batten-hung
- Framing deflection, because tile is heavy and older framing was not always sized for it
Common questions
Why do quotes vary so much?
Usually because they are not quoting the same job. Deck repair, underlayment specification and disposal are the three most commonly left out, and they are the three that appear later as extras.
Is financing worth it?
It depends on what the alternative is. Spreading a replacement over ten years costs interest; patching a failed roof for three more winters costs more than the interest, and usually costs a ceiling as well.
The honest summary
In most cases the tile is fine and only the underlayment has failed. Anyone quoting a full tear-off and new tile on a roof with sound tile is quoting the wrong job. Ask specifically whether your existing tile can be relaid, and how much of it is expected to break in handling — ten per cent is normal, and it should be priced up front.
