Can Your Framing Carry a Tile Roof? — Homeowner Checklist
The short list that adds years to a tile roof in North Hollywood, and the jobs that are pure theatre.
Knowing what to look at turns a vague worry into either a short list or an early night. Most of this can be done from the ground with binoculars and from inside the attic with a torch — no ladder, no risk, and it tells you whether to call anyone.
What actually matters
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.
What you can check yourself
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.
What is specific to Los Angeles
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.
The full inspection list
- 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
How often should I check?
Twice a year — before the rains and after the first real storm — plus once after any significant wind event.
Do I need to get on the roof?
No, and preferably not. Binoculars from the ground and a torch in the attic find most of it, and walking a roof causes damage of its own, particularly on tile.
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.
