Canales are the most NM-specific leak source there is, and the most commonly misdiagnosed. I inspect every canale and scupper on your roof — pan slope, soldered liner corners, parapet penetration, and downspout extension — and tell you which ones are actively leaking versus which are just washing the stucco. You get a written, canale-by-canale scope you can hand to any roofer for a bid.
Per-canale pan slope and standing-water check
Sheet-metal liner lap, solder, and corner integrity
Parapet penetration and cap-metal transition audit
Scupper, conductor head, and downspout sizing
Interior stain correlation (wall vs ceiling)
Written per-opening scope with cost bands
Full roof walk with a numbered inventory of every canale and scupper. Pan slope measurement and standing-water check at each opening. Sheet-metal liner inspection — lap length, solder joints, corner splits. Parapet penetration and cap-metal transition audit at each canale. Scupper throat, conductor head, and downspout sizing against drainage area. Stucco splash-back versus actual water-entry differentiation. Interior correlation: which wall stain maps to which opening. Written per-opening scope with prioritized repairs and cost bands.
Pueblo, territorial, and flat-roof homeowners with stucco staining below the roofline. Owners with interior wall stains that no roofer has been able to trace. Adobe and historic property owners in Santa Fe, Corrales, and the North Valley. Buyers under contract on a flat-roof home with visible canale wash. Anyone handed a full-parapet-rebuild quote for what may be a single bad pan.
Free Walk-Around — $0 (verbal findings, no written report) Standard Canale Report — $349 Detailed Per-Opening Report w/ Photo Map — $599 Multi-building / commercial parapet — quoted by linear foot Most homes land at $349. A single re-lined canale at $350–$700 beats a $6,000 parapet rebuild you didn't need.
Almost always the metal pan liner, not the parapet. Canales are cut through the parapet, so the pan has to carry water past the wall. When the liner is short, unsoldered at the corners, or pitched back toward the roof, water gets behind the stucco and shows up as an interior stain on the wall below — not the ceiling. I probe pan slope and liner laps on every canale on the roof.
The stain is usually splash-back, which is cosmetic. The problem is what caused the splash: no downspout extension, a short pan, or a canale sized too small for the drainage area. I separate the cosmetic wash from an actual water-entry point so you don't pay for a repair you don't need.
Re-lining a single canale with new soldered sheet metal runs roughly $350–$700 each. Adding a scupper extension or conductor head is $200–$450. A full parapet cap-metal replacement is a different scope entirely. My report tells you which of the three you actually need, canale by canale.

I've watched too many neighbors sign contracts they didn't understand for roofs they didn't need. That stops with a written report they own.
