Ontario Roof Pros provides professional storm damage restoration in Ontario, CA for residential and commercial properties across the Inland Empire. The storms that hurt roofs in this valley are the winter atmospheric rivers, and on a low-slope roof the damage is usually not the wind at all. It is the water that could not leave the roof fast enough.
Ponding is a structural load. One blocked drain on a wide warehouse roof can hold thousands of gallons in a single low spot, deflect the deck, and make that low spot deeper with every hour the rain keeps falling. Overflow scuppers exist for exactly that hour, and on older buildings we routinely find them painted shut, screened over, or set so high that the roof is carrying several inches of water before they do anything at all.
Our sequence is drain the water, stop the entry, then assess. Pumps and vacuum equipment come before any membrane work, because welding a patch into standing water is theatre. Once the plane is dry we can see which laps opened, which fastener plates pulled through, which insulation has gone heavy underfoot, and whether the deck itself is holding a permanent dish where the water sat.
On houses the failures are in the details: a lifted ridge, a valley that overshot its metal, a slipped tile course, a wall flashing that let water in behind the stucco. We check sheathing from inside the attic, because a stained rafter points at the entry far better than the shingle above it does, and we photograph the framing before any insulation goes back over it. Wet insulation gets bagged and removed rather than fluffed and left.
Documentation happens before repair, not after it. Dated photographs, moisture readings, a marked roof plan and a written scope give an adjuster something to work from, and give you a baseline if the same detail fails again next season. On commercial buildings that file is also what keeps a manufacturer's warranty from being denied because nobody can prove what happened or when.
Not every roof needs restoration after a storm. Plenty need a clean, a drain retrofit, new strainers and one maintenance visit each November, which is a maintenance line rather than a capital project. When that is the honest scope, that is the scope we quote, and we will tell you which of the two you are looking at on the first visit.
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 storm damage restoration
The difference between storm damage restoration that lasts and storm damage restoration 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.
