Ontario Roof Pros provides professional roof coatings & restoration in Ontario, CA for residential and commercial properties across the Inland Empire. A coating is a legitimate way to add years to a sound roof and a very expensive way to hide a wet one. A core cut decides which situation you are in, and no brochure can answer that question for you.
Good candidate: a fifteen-year-old warehouse membrane with dry insulation, tight laps, working drains and a chalky surface. A silicone or acrylic restoration system over that, with reinforced seams, primed flashings and a measured dry film thickness, costs a fraction of a tear-off, produces no landfill, and carries a warranty you can renew later with another coat rather than another roof. Nothing goes to landfill and nothing stops shipping.
Bad candidate: saturated insulation, blisters that pump water underfoot, open laps at the perimeter. Coating that adds weight, traps moisture and converts a repairable roof into a full tear-off with a disposal bill attached to it. We take cores first and walk away from the coating when they come back wet, even when the coating is the specific job the client called us about and had already budgeted for this quarter.
Metal is the other strong use case. A rib-conforming system with fabric over every fastener line and lap seals the thousands of small penetrations a screw-down panel already has, stops the rust where it starts at the fastener, and does it without shutting the building down or dropping debris onto whatever is stored underneath. Rusted panels get treated before anything else goes on.
Reflectance is a side benefit that pays for itself. Ontario sits in California climate zone 10, where cool-roof requirements reach most low-slope non-residential re-roofing, and a CRRC-listed product keeps the compliance paperwork simple when the permit is pulled. On a dark roof over conditioned space, the summer difference shows up on the utility bill rather than only in the specification, and the membrane underneath runs cooler and ages slower.
Preparation is the whole job. Pressure cleaning, rust treatment or primer where the substrate needs it, seams reinforced with fabric, then two coats at the specified thickness with wet mil readings logged as we go. Coatings fail from thin application and dirty substrate far more often than from anything wrong with the product in the pail, and a warranty will not save a roof that was coated over dust.
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 roof coatings & restoration
The difference between roof coatings & restoration that lasts and roof coatings & 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.
