Ontario Roof Pros provides professional skylights & roof hatches in Ontario, CA for residential and commercial properties across the Inland Empire. Skylights in this city are mostly not on houses. They sit in long rows on warehouse roofs, acrylic domes bringing daylight down onto racking and taking a real bite out of the lighting bill in a building that runs two shifts.
Those domes are also the oldest thing on many of these roofs. Twenty years of ultraviolet exposure leaves acrylic brittle and yellowed, curb flashings shrink back from the corners, and the unit becomes both a leak and a fall hazard for anyone servicing rooftop equipment near it. A brittle dome will not hold a person who steps on it, and from above it does not look any different from one that would.
Replacement is straightforward and best done in runs rather than one at a time. New prismatic polycarbonate units on rebuilt curbs, membrane flashed up and over the curb with metal counterflashing above it, and either an integral load-rated screen or a compliant guard so the opening is protected from above for whoever walks that roof next. Doing a whole row in one visit cuts the cost per unit substantially and only closes the aisle below once.
Residential work is different in kind. Deck-mounted units with the manufacturer's flashing kit outperform curb-mounted ones on a shingle roof, and the kit matched to the covering does more for the leak than the glazing does. Tubular units are excellent in hallways, stairwells and interior bathrooms where a full framed shaft would cost several times as much and take a week of drywall work.
The repair we usually decline is resealing a crazed, chalky dome. Sealant on brittle acrylic buys a single season, and you pay the mobilisation twice for the privilege. Replacing the unit costs more once and stops the calls, which is the cheaper answer over any span of time long enough to matter to the person who owns the building and pays for the lift twice.
We handle roof hatches and smoke vents on the same visit: new gaskets, corrected curb height where the membrane was built up around it, flashing on the ladder side, and hold-open arms that actually work. A hatch that will not latch is how a February storm gets into a building, and it is usually the cheapest item on the whole report by a wide margin.
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 skylights & roof hatches
The difference between skylights & roof hatches that lasts and skylights & roof hatches 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.
