The tile is not the whole roof
Tile may remain visually serviceable while underlayment or flashing reaches the end of its useful condition. A reroof can involve lifting and resetting reusable tile, installing new tile, replacing underlayment, repairing deck areas and rebuilding flashing details.
Verify structural assumptions
If a project changes from a lighter roof to tile, structural suitability should be verified by the appropriate local professional rather than assumed from an online estimate.
| Scope item | Planning question |
|---|---|
| Tile | New tile, salvage/reset or partial replacement? |
| Underlayment | What product and coverage? |
| Attachment | Battens, direct fastening or another method? |
| Flashing | Valleys, walls, chimneys and penetrations rebuilt? |
| Breakage | How are damaged or discontinued tiles handled? |
Access and handling affect labor
Tile is heavier and more fragile to move than many sheet or shingle products. Multi-story access, staging distance and protection of finished surfaces can add handling time.
Compare underlayment, not just tile brand
Ask what is underneath the visible tile and how penetrations and transitions are detailed.
