Look beneath the visible tile
A tile roof’s visible surface is only part of its water-shedding assembly. A leak can involve broken or displaced tiles, underlayment, flashing or transitions. The diagnosis should establish the cause before deciding whether a local repair or broader work is appropriate.
Check structural suitability before changing materials
Tile weight and attachment requirements must suit the building. Changing from another material to tile should not be treated as a cosmetic swap. Ask whether structural evaluation is needed and how the proposed assembly will meet applicable requirements. Existing tile roofs also need careful assessment before changing products.
Repairs require careful access
Walking on tile can break otherwise serviceable pieces. Leave roof access to qualified professionals and take initial photos from safe ground-level locations. A repair proposal should explain the area to be opened, how tiles will be handled and how replacement pieces will be sourced if matching is difficult.
Underlayment and flashing decisions
Ask whether work is limited to a few tiles or extends to the layers below. Where underlayment or flashing is deteriorated, replacing only visible broken pieces may not solve the water-entry problem. If tiles are proposed for reuse, clarify condition standards, breakage allowances and what happens when matching pieces are unavailable.
Plan drainage and future access
Valleys, gutters and areas around penetrations can collect debris. Plan suitable maintenance access and discuss future work on skylights or solar equipment. A well-defined estimate separates tile replacement, underlayment work, flashing, deck repairs and disposal so you can compare alternatives.
