Usual suspects
| Where | Why |
|---|---|
| Parapet caps and corners | Cracks let water into walls |
| Canales | Clogged with leaves, or cracked at the wall |
| Skylights | Dried sealant at the curb |
| Vents and flues | Open flashing, wood stove chimneys |
| Low spots | Standing water wears the coat through |
| Old cooler openings | Patched poorly after removal |
How we trace it
We start inside — where the stain is, and when it appears — then work the roof: probing foam, checking every wall joint and opening, and water-testing when needed.
The fix
- Remove wet foam and let the area dry
- Rebuild with new foam; fix slope if water was sitting
- Reinforce joints and cracks
- Reseal or replace canales and flashing
- Coat the repair
If the whole coating is worn, a spot repair may not hold long. We'll say so. See foam roof recoating.

Common questions
Why does my leak only show up in big storms?
Often a canale backs up or water rises above a crack only when there's a lot of it.
Can you coat over a leak?
Not until wet foam is removed. Coating over it traps water.
