Walking a Tile Roof Without Breaking It
What a real inspection covers on a tile roof in Central LA, top to bottom.
A roof inspection is only as good as what gets looked at, and a lot of what gets called an inspection is a walk round the garden with a phone camera. This is what a real one covers on a tile roof in Central Los Angeles.
What actually matters
The tile is not what keeps water out. The tile is a rain screen and a sunshade; the underlayment beneath it is the actual waterproofing, and it is the part with the shorter life. An inspection that does not account for that is looking at the wrong layer.
The detail that is usually left out
An inspection is only as good as what gets looked at, and photographs of specific defects are what let you get a second opinion without a second visit. Bird stops, eave closures and the mortar at the ridge are what most quotes leave out. Leave them off and you have an open roof edge that invites nesting, debris and, in the fire zones, embers. Anything under half an hour on an average house has skipped something.
What is specific to Central Los Angeles
Weather is only half of it here. Buildings sit close together, roofs are often overlooked by taller neighbours, and access is genuinely difficult on a lot of properties. Sustained heat and UV do the material damage; the density decides how the work has to be scheduled and staged. Older multi-family and mixed-use is common, usually low-slope behind a parapet, and often with several decades of layered repairs on top.
The full inspection list
- Underlayment age and condition, checked by lifting tile rather than guessing
- Broken, slipped and previously face-nailed tiles across the field
- Batten condition and fixing, particularly at the eave course
- Valley metal, which usually corrodes before the underlayment fails
- Ridge and hip mortar or mechanical fixing, and any movement in it
- Bird stops and eave closures, present and intact
- Flashing at walls, chimneys and every penetration through the field
Common questions
Should I expect photographs?
Yes, and of the specific defects rather than general views. Photographs are what let you get a second opinion without a second visit.
Is a free inspection worth having?
It is, provided the report is written and itemised. What you are watching for is an inspection that finds only work the inspector happens to sell.
The honest summary
Judge a tile roof by its underlayment, not its tile. A roof that looks flawless from the driveway can be two winters from a ceiling repair, and the only way to know is to lift a few tiles and look. In Central Los Angeles the thing to watch is parapet and counterflashing detail, layered previous repairs, and safe access for the work itself.
