Colton's Commercial Roofer for the Inland Empire, Los Angeles & Orange County

When Santa Ana winds funnel through the Cajon Pass every fall, they don't just rattle windows — they pry up loose flashing, lift membrane seams, and turn a small blister into a leak over a warehouse full of inventory. Hub Roofing is the commercial roofer Colton, CA property owners call when that happens, and we've spent 35+ years learning exactly how Inland Empire heat, high winds, and flash storms wear down a flat or low-slope roof.

Whether your building sits in a Colton industrial park, a Fontana distribution center, a Riverside strip mall, or a mid-rise in Los Angeles or Orange County, we know what your roof is up against — and we show up with a plan, not a guess.

Built for the Way Southern California Weather Attacks a Commercial Roof

A commercial roof in the Inland Empire doesn't fail the same way one does on the coast, and it doesn't fail the same way one does downtown LA either. Around Colton, San Bernardino, and Fontana, triple-digit summer heat bakes TPO and EPDM membranes and dries out asphaltic roofing faster than manufacturers' spec sheets ever account for. Then fall arrives and Santa Ana winds — funneled and accelerated through the Cajon Pass — get under parapet flashing, rooftop curbs, and loose membrane edges, turning small installation gaps into full uplift failures.

Closer to the coast in Los Angeles and Orange County, the marine layer works differently but does just as much damage: moisture condenses under insulation and around penetrations, corroding fasteners and rusting rooftop equipment from the inside out long before a leak becomes visible from below. Add in salt air along the OC coastline and you've got metal roofing and HVAC curbs breaking down years ahead of schedule.

We build and repair roofs to handle all three conditions, because most of our clients' commercial property portfolios span more than one of these microclimates at once.

Commercial Roofing Services From a Local Crew That Answers the Phone

No call centers, no subcontractor churn — the same Hub Roofing crew handles your project from inspection to final sign-off.

New Commercial Roof Construction & Roof Systems

Single-ply membrane (TPO, PVC), built-up roofing (BUR), modified bitumen, torch-down, and elastomeric reflective coatings — installed to pass city permitting and Title 24 energy compliance the first time. We size and detail every roof system to the building's actual traffic, drainage, and rooftop equipment load, not a one-size-fits-all spec.

Commercial Roof Repair & Emergency Leak Response

A leak over a retail floor or a server room can't wait for a callback next week. We trace commercial leaks to their actual source — not just the spot where water is showing up inside — and get a permanent repair done, not a patch that reappears at the next storm.

Roof Maintenance Programs & Certifications

Scheduled inspections catch loose flashing, clogged drains, and membrane wear before they become claims. We also issue the detailed roof certifications and inspection reports that banks, insurers, and buyers require during refinancing or a property sale.

Roof Restoration & Recover Systems

When a roof still has structural life left but the surface is failing, a recover or restoration system can add another decade of service without the cost and disruption of a full tear-off — a call we make honestly, not automatically.

Commercial Roofing Across the Inland Empire, Los Angeles & Orange County

A local roofing contractor near you, wherever "near you" happens to be across Southern California.

Inland Empire — Our Home Turf

Colton, San Bernardino, Fontana, Rancho Cucamonga, Ontario, Redlands, and Rialto have seen a wave of new distribution centers and warehouse space along the I-10 and I-15 corridors. Those large, flat commercial roofs take the brunt of Cajon Pass wind gusts and summer heat, and we service more of them than almost any other contractor in the region.

Los Angeles County

Much of LA's commercial building stock is decades old, with roofing that predates current Title 24 energy codes. We handle reroof and recover projects that bring older strip malls, warehouses, and mixed-use buildings up to current standards while managing the coastal marine layer's slow, hidden moisture damage.

Orange County

HOA-managed business parks, hospitality properties, and retail centers across Orange County deal with salt-laden coastal air corroding metal roofing and rooftop equipment, plus occasional Santa Ana wind events that hit harder than most property managers expect.

Commercial Roofing FAQ

Questions we hear most from property managers and business owners across Southern California.

We recommend two inspections a year: one before Santa Ana wind season in the fall and one in spring after winter storms have had a chance to expose any weak seams, ponding areas, or lifted flashing. Buildings with rooftop HVAC units or heavy foot traffic from other trades often need a third check mid-summer, since triple-digit heat accelerates membrane wear.
Yes. We regularly schedule commercial roof repair and restoration work overnight or on weekends for retail centers, warehouses, and logistics facilities that can't afford daytime downtime. We'll work out a schedule with your property manager or operations team before a crew ever shows up.
Yes. We complete detailed roof inspections and provide written certifications and reports that satisfy insurers, lenders, and buyers during refinancing, underwriting, or a property sale. Reports include photos, remaining useful life estimates, and repair recommendations.
