Chino Hills Roofing & Low-Slope Membrane Services — Licensed & Insured

Call (844) 511-2320 or send the form and we schedule a site visit in Chino Hills, usually within a couple of days. You get a written, itemized free estimate with materials and scope spelled out — no verbal ballpark, no pressure, and no charge whether you hire us or not. Se habla español.

We also serve Montclair, CA and the rest of the Inland Empire. Everything starts at the Ontario Roof Pros homepage.

Ontario Roof Pros covers the same range of work in Chino Hills that we do in Ontario — nothing is carved out because the address is a few miles up the road:

• Roof Replacement — Replacement here comes down to one question: can the building keep working while the roof comes off? On a distribution building that answer drives the whole sequence, and on a house it decides how long the framing sits open to the sky.
• Roof Leak Repair — A leak on a nearly flat roof almost never drips where it entered. Water runs along the flute of a steel deck until it finds a seam or a fastener, so the stain in the office ceiling can sit forty feet from the actual breach in the membrane.
• Storm Damage Restoration — 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.
• Hail Damage Roofing — Damaging hail is uncommon in Ontario. A cold winter cell can drop pea to marble sized stones across the valley, and it does happen, but most roofs we are asked to inspect for hail turn out to have something else wrong with them.
• Wind Damage Roofing — Wind failure on a large low-slope roof begins at the corners. Uplift pressure is highest in the corner and perimeter zones, so a membrane fastened at field spacing all the way to the edge lifts there first and peels inward from a single loose sheet.
• Roof Inspections & Moisture Surveys — A warehouse roof is an asset with a service life. The buildings that get twenty-five years from a membrane are the ones looked at twice a year, and the ones that get twelve are the ones nobody visited between leaks.

Chino Hills sits in San Bernardino County with a population of roughly 78,411, close enough to Ontario that crews move between the two constantly. Local landmarks and corridors residents know well include Chino Hills State Park, the BAPS Shri Swaminarayan Mandir.

Local knowledge is not a marketing line here. Chino Hills properties share soil, weather, permit rules and construction eras with the rest of San Bernardino County, and a roofing contractor who works the area weekly already knows what fails locally and what holds up. That is the difference between a bid and an accurate bid.
