Where is it showing up inside?
Water enters at one point and leaves at another, so the stain on your ceiling is a clue rather than an address. Open the line that matches what you're seeing.
ANear an outside wall, or below a canale
BAlong the line where the ceiling meets an exterior wall
CAround a skylight, vent, chimney or swamp cooler
DIn the middle of a room, away from anything
Whichever line matches: don't go up on a low-slope roof in wet or freezing conditions to check. A wet membrane is more slippery than it looks.
Where Santa Fe roofs actually leak
Water on a low-slope roof travels. It enters at a failure point, runs along the decking or between layers, and shows up inside wherever it finds a path down. This is why chasing the stain on the ceiling is usually the wrong move, and why a good repair starts with an inspection rather than a bucket of sealant.
The usual suspects, roughly in order:
- Canales. Every drop of water on the roof is routed through them, and the metal-to-membrane joint at the canale takes constant thermal movement.
- Parapet junctions. Where the roof surface turns up into the parapet wall. Stucco cracks above this line will feed water straight in.
- Flashing. Around vents, skylights, chimneys, and any penetration.
- The membrane field — genuinely last, unless the roof is at end of life or was physically damaged.
Repair or replace?
Nobody can answer this from a photo, but the shape of the decision is consistent:
| Points toward repair | Points toward replacement |
|---|---|
| One identifiable entry point | Multiple leaks in different areas |
| Roof is mid-life and the surface is sound | Membrane is brittle, cracked, or at end of life |
| Decking underneath is dry and solid | Soft or rotted decking |
| Previous repairs are holding | A history of patch-on-patch repairs |
Be skeptical of a contractor who reaches "you need a full replacement" before inspecting, and equally skeptical of one who'll seal any leak for a few hundred dollars without looking at why it's leaking. If a replacement is genuinely recommended, it needs a city permit — see permits.
What to do while you wait
If it's actively leaking: catch the water, move what can be damaged, and photograph everything — where it's dripping, when, and how hard it was raining. That timeline is genuinely useful to whoever inspects it, and to your insurer if a claim follows. Don't go on the roof yourself in wet or freezing conditions; a low-slope roof with a wet membrane is more slippery than it looks.
If that's not the shape of it
Then it may be a stucco repair that presents as a roof leak. There's a three-check triage for that.
Stucco repair → It's patch on patch by nowA history of repairs that keep failing is the clearest signal you're pricing a replacement, not a fix.
