Ontario Water Restoration Pros provides professional storm & wind-driven rain damage in Ontario, CA for residential and commercial properties across the Inland Empire. Ontario does not get hurricanes, and pretending otherwise helps nobody. What we get is a few very wet days a year landing on flat roofs that were built to shed water through a drain, plus Santa Ana wind events that pull at membrane seams and flashing.
That combination produces a specific loss. A low-slope roof holds water by design until the internal drains take it away. Put a plastic bag, a bird's nest or a season of debris over a clamping ring and the water has nowhere to go but sideways, until it finds a penetration, a curb, or a seam the wind opened three weeks earlier.
By the time it shows inside, it rarely shows where the breach is. Water runs along the flutes of a metal deck and appears sixty feet away over a different tenant's ceiling. We trace it back with thermal imaging and moisture meters rather than opening ceiling tiles at random, then dry the deck, the insulation and the wet gypsum below it.
Wind damage without water intrusion is not our job, and we will say so on the phone. If the membrane lifted, the cap flashing is gone, or a rooftop unit's panel blew off and the interior is dry, you need a roofer and possibly a mechanical contractor. Calling a restoration company first adds a bill and no value, and we would rather refer it out.
Where we are worth the call is when the interior is wet and the building has to keep operating. Temporary tarping and shrink wrap buys time, containment keeps the affected bay closed off from the rest of the floor, and drying starts the same visit. We also photograph the drain, the overflow scupper and the debris, because a maintenance argument with an insurer usually turns on that one picture.
With 15+ years of experience, our licensed and insured team brings the right materials and equipment to every job — desiccant dehumidifiers for large open volumes, low-grain refrigerant dehumidifiers, HEPA-filtered negative air machines, 6-mil poly critical barriers and hard containment, ASTM F2170 in-situ concrete relative-humidity probes, penetrating and non-penetrating moisture meters — and backs the work with a written workmanship warranty. We serve Ontario and nearby communities including Chino, Chino Hills, Montclair, Upland.

Materials, equipment and how we do storm & wind-driven rain damage
The difference between storm & wind-driven rain damage that lasts and storm & wind-driven rain damage that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with desiccant dehumidifiers for large open volumes, low-grain refrigerant dehumidifiers, HEPA-filtered negative air machines, 6-mil poly critical barriers and hard containment, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Ontario job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. 15+ years of water damage work in the Inland Empire means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
