Ontario Roof Pros provides professional emergency tarping & water control in Ontario, CA for residential and commercial properties across the Inland Empire. On a house we tarp. On a warehouse membrane there is often nothing to tarp to, so the emergency becomes water control: pull the standing water off the deck, weld a temporary patch, and protect whatever sits under the leak inside the building.
The first call sets priorities. In a tenant-occupied building, inventory, racking and electrical panels come before the roof. Sheeting and containment over the racks buys the hour we need above, and it keeps a roof leak from turning into a stock loss claim with a much larger number attached to it than the roof repair was ever going to carry. Wet cardboard cannot be salvaged.
For membrane, a proper temporary repair is a cleaned and dried area, a heat-welded patch or reinforced cover tape, and a note on the roof plan so the permanent fix happens in daylight with the right material on the truck. On a built-up or modified roof in the rain, wet-patch and fabric will hold until the surface can dry out enough to take a real repair, and we come back for that rather than leaving it.
Tarping a house is a technique, not a blue sheet and some bricks. Battens screwed through the tarp into the deck, edges carried over the ridge rather than stopped short of it, fasteners placed where the permanent repair will remove them anyway, and no water diverted onto an adjacent roof, into a valley, or down a wall that was dry an hour ago.
Inside, we relieve trapped water instead of letting it find its own way out. A small controlled hole in a bulging ceiling drains into a bucket and saves the drywall around it. A soaked blanket of attic insulation gets pulled before it flattens permanently and stops doing the job it was paid to do, and the framing gets photographed while it is still visible, because that photograph is worth having if a claim follows later.
Tarping is triage with a date on it. We come back with a scope, photographs and a real price, and we tell you how long the temporary work can be trusted rather than leaving it up until it fails on its own in the next storm. Anything we install as temporary gets priced as temporary, and it gets removed by the permanent repair.
Our licensed and insured team brings the right materials and equipment to every job — tapered polyisocyanurate built to a quarter-inch-per-foot fall, hot-air-welded PVC with a KEE plasticizer, tested ANSI/SPRI ES-1 edge metal and coping, two-ply SBS modified bitumen set in cold adhesive, retrofit drains sleeved into existing cast-iron leaders, walk pads routed between rooftop units — 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 emergency tarping & water control
The difference between emergency tarping & water control that lasts and emergency tarping & water control that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with tapered polyisocyanurate built to a quarter-inch-per-foot fall, hot-air-welded PVC with a KEE plasticizer, tested ANSI/SPRI ES-1 edge metal and coping, two-ply SBS modified bitumen set in cold adhesive, 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. Years of roofing 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.
