Clay or concrete tile roof on a Marina Mediterranean or a Mission Revival home — leaking, cracked, or due for attention? Send a few details and you’ll get a straight answer on what it actually needs, from one vetted, licensed San Francisco roofer.
Tell us whether it’s clay or concrete tile, roughly how old the roof is, and what’s prompting the call. With tile, the fix is often not what people expect — the tile usually isn’t the problem.
Tile is rare in San Francisco — and that changes the job
Most of the city is composition and flat roofs; tile is the exception, found mainly on the Mediterranean and Spanish Revival homes in the Marina, parts of St. Francis Wood, Forest Hill, and scattered period houses elsewhere. Because it’s uncommon here, a lot of general roofers aren’t set up to work on it well — and tile is unforgiving of walking on it wrong. That rarity matters for you in two ways: getting someone who actually knows tile, and sourcing replacement tile that matches a roof that may be decades old and no longer in production.
The single most important thing to understand about a tile roof: the tile is not what waterproofs the roof. The clay or concrete tile sheds the bulk of the water and protects what’s underneath, but it’s the underlayment beneath the tile that actually keeps water out. On a tile roof in SF, when a leak appears, the tile is usually fine — it’s the underlayment that has aged out, or a flashing that has failed. That’s why a good tile repair is often a matter of lifting tile, replacing the underlayment and flashing in the affected area, and re-laying the same tile, rather than a whole new roof.
What tile roofs here actually need
- Underlayment replacement — the real fix for most tile leaks; the tile is lifted, the failed felt or membrane beneath is replaced, and the tile goes back down.
- Flashing repair at valleys, walls, chimneys, and penetrations — and near the coast, replacing flashing that salt air has corroded under the tile.
- Cracked-tile replacement — broken tiles from foot traffic, debris, or age, matched to the existing roof as closely as the tile market allows.
- Tile sourcing and matching — tracking down or salvaging tile to match a discontinued profile and color, which is half the challenge on an older roof.
- An honest structural read — tile is heavy, so if a full re-roof is on the table, the framing’s ability to carry it (or the case for a lighter material) gets discussed up front.
Common questions
My tile roof is leaking — do I need a whole new roof?
Usually not. On a tile roof, a leak almost always means the underlayment or a flashing has failed, not the tile — and those can be repaired in the affected area by lifting the tile, replacing what’s underneath, and re-laying the same tile. A full re-roof only makes sense when the underlayment is failing across the whole roof at once, which tends to happen when the underlayment reaches the end of its life all over. The site visit tells you which situation you’re in rather than defaulting to the expensive answer.
Can you match my old tile if some are broken?
Often, with some legwork. Tile profiles and colors change over the decades, and a roof from the 1920s or the 1970s may use a tile no longer made. The options are salvaged matching tile, a current tile close enough to blend, or relocating original tile from a hidden area to the visible slope and putting the near-match out of sight. Matching is part of the craft on an older SF tile roof, and being realistic about how close a match is possible is part of the honest answer.
Should I walk on my tile roof to check it myself?
Please don’t. Tile cracks under foot traffic if you don’t know exactly where and how to step, and a well-meaning look around can turn a sound roof into a repair list. It’s also genuinely hazardous on SF’s steep slopes. If something looks off, send a description or a photo from the ground and it can be assessed properly from there — that’s safer for you and for the roof.
