Where leaks start
| Spot | Why |
|---|---|
| Parapet caps and corners | Cracks let water into walls |
| Canales and drains | Clogged or cracked at the wall |
| Skylights | Dried sealant |
| Vents and flues | Open flashing |
| Cooler and AC curbs | Drips and foot traffic wear the coat |
| Low spots | Standing water wears through |

The repair
- Trace the leak from inside to the roof
- Remove wet material and dry the area
- Rebuild and reinforce
- Reseal drains, flashing and openings
- Coat the repair
If the whole coat is worn, a spot repair may not last. See flat roof coating.

Common questions
Can you just coat over a leak?
Not if the foam is wet. That traps water.
Why does it only leak in big storms?
Often a drain backs up only with heavy rain.
