NM monsoon dumps a season of rain in eight weeks. Canales overflow, parapets shift, and drains that worked in June clog by August. I inspect before and after to catch what the storms are doing — with photos any insurer or roofer can act on.
Canale slope, sealant, and outflow test
Parapet cap and stucco crack survey
Drain and scupper flow measurement
Ponding-water mapping at every low point
Flashing displacement and sealant condition
Pre-monsoon prep list or post-storm damage report
Full walk with canale flow testing (bucket-and-stopwatch method). Parapet caps, counterflashings, and stucco terminations documented. All drains and scuppers cleared and flow-tested. Ponding-water depth measured after simulated pour. Written report: pre-monsoon prep items OR post-storm damage list with photos and repair scope.
NM homeowners with flat or low-slope roofs (canales are the #1 monsoon leak). Owners after a strong monsoon cell who want damage documented. Property managers preparing portfolios for the season. Buyers under contract when closing lands mid-monsoon.

Roughly July 4 through mid-September. The strongest cells hit late afternoon and drop 1–2 inches of rain in under an hour — the exact profile that overwhelms marginal drains and finds every weak seam.
Both if you can. Pre-monsoon (May–June) catches drain blockages, cracked sealant, and lifted flashings before they leak. Post-monsoon (October) documents what the season actually did — critical if you plan to file a claim.
Canale sealant cracking, parapet cap displacement, and ponding water at drains. The leak shows up in November when the first cold-front rain hits, but the damage happened in July.

RTU flashing and vibration leak source audit.

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.
