The deciding factor: moisture
A dry roof can be recoated or foamed over. A wet roof can't — trapped water leads to blisters and rot. We probe for soft spots before recommending anything.
Options
| Condition | Usually |
|---|---|
| Coating worn, foam dry | Recoat |
| Foam eroded, roof mostly dry | New foam plus coating |
| Wet insulation, rotten deck, many layers | Tear-off and TPO |
