Ontario Elite Patio Covers provides professional sunrooms & glazed enclosures in Ontario, CA for residential and commercial properties across the Inland Empire. A glazed sunroom is a large plane of glass held up by aluminum. In Ontario the two questions that decide whether it works are how it handles a gust off the pass and how often somebody has to wash it.
Start with the glass. Wind pressure on a big fixed pane is a structural load, not a detail, and the framing member spacing has to reflect the exposure of the site. A foothill lot at the north end of the city sees stronger gusts than a sheltered infill lot two miles south. We size for the site rather than the catalogue.
Then the cleaning. Glazing here does not stay clean. Fine basin particulate settles on every horizontal and sloping surface, and a glass roof shows it within days. We pitch roof glazing steeply enough to shed rather than hold, and we keep the outside reachable from the ground. A roof needing scaffolding to wash stays dirty.
Seals matter for the same reason. Dry, gritty air works its way into any gap, and the grit is what destroys a gasket, not the water. That means captured gaskets and structural sealant rather than snap-on trim, and weep paths that genuinely drain instead of slowly packing with silt.
Heat deserves a sentence. Low-emissivity glass on the west and south is not optional in the Inland Empire, and shade above the roof glazing does more than any coating. But that is a solved problem once the glass is specified properly, whereas wind loading and airborne grit are with you permanently.
Permitting is a full building submission through the City of Ontario, with energy compliance under Title 24 and seismic detailing at the connections. It takes longer than a patio cover, and we plan the schedule around that rather than promising a summer that was never available.
With 15+ years of experience, our licensed and insured team brings the right materials and equipment to every job — foam-core insulated roof panels, powder-coated extruded aluminum, embossed wood-grain composite beams, engineered concrete pier footings, designed uplift hold-down connections, louvered adjustable-pitch systems — and backs the work with a written workmanship warranty. We serve Ontario and nearby communities including Rancho Cucamonga, Upland, Chino, Chino Hills.

Materials, equipment and how we do sunrooms & glazed enclosures
The difference between sunrooms & glazed enclosures that lasts and sunrooms & glazed enclosures that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with foam-core insulated roof panels, powder-coated extruded aluminum, embossed wood-grain composite beams, engineered concrete pier footings, 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 patio cover 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.
