Fontana Roof Pros provides professional commercial roofing in Fontana, CA for residential and commercial properties across the western Inland Empire. Our commercial work is small buildings: strip retail along Foothill Boulevard and Sierra Avenue, churches, medical and dental suites, auto shops, older two-storey mixed-use. Three thousand to twenty thousand square feet, and a roof that has to be worked on without closing anyone's business.
At that size the roof is rarely the whole problem. The rooftop equipment is. Packaged air-conditioning units sit on curbs that were flashed once by whoever set them, condensate lines discharge onto the membrane and grow a stain that becomes a soft spot, disconnects and gas lines are supported on wood blocks that have crushed into the roof, and every service technician who visits walks the same path across it.
So our scope on a small commercial roof includes the things that actually leak. Curbs re-flashed with target patches and welded corners. Condensate piped to a drain rather than onto the field. Equipment set on pipe supports and sleepers. And walkway pads along the service routes, which matter more here than in a mild climate: a membrane at summer surface temperature marks and gouges under a boot in a way the same membrane never does in April.
Reflectance carries real money on these buildings. A white single-ply on a low-slope commercial roof cuts the heat load reaching the deck, and the packaged units above it are drawing air that is dozens of degrees cooler than it would be over a dark cap sheet. California's nonresidential energy standards already push this direction for low-slope roofs; the operating cost is what makes an owner glad about it.
Sequencing is the rest of the job. We phase by section so tenants stay open, work early to get material down before the surface gets too hot to handle safely, keep the parking and the entrances clear, and give the property manager a written schedule with the sections and dates on it. Nobody finds out on the day that their entrance is behind a dumpster.
We also run annual maintenance for owners who prefer that to surprises: a documented inspection with photographs, drains and scuppers cleared, laps and curbs checked, small repairs completed on the same visit, and a written remaining-life note so a re-roof lands in a budget year rather than in a bad week. On a building with tenants, that note is usually worth more than the repairs it comes with.
Our licensed and insured team brings the right materials and equipment to every job — cool-rated architectural shingles, high-temperature SBS-modified underlayment, batten-set concrete tile with a one-inch air space, Kynar 500 PVDF standing-seam panels, heat-welded TPO membrane, reflective elastomeric coating — and backs the work with a written workmanship warranty. We serve Fontana and nearby communities including Rialto, Bloomington, Colton, Grand Terrace.

Materials, equipment and how we do commercial roofing
The difference between commercial roofing that lasts and commercial roofing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with cool-rated architectural shingles, high-temperature SBS-modified underlayment, batten-set concrete tile with a one-inch air space, Kynar 500 PVDF standing-seam panels, 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 Fontana 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 western Inland Empire means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Fontana Chooses Fontana Roof Pros
- ✓Every estimate names the product and its Cool Roof Rating Council listing, so the reflectance claim is documented rather than asserted
- ✓Inspections include the attic: deck condition, a temperature reading, and net free vent area measured against attic floor area
- ✓Roofs are graded and quoted plane by plane, because the west face here fails years ahead of the north
- ✓We decline shingle coating jobs and hail claims on heat-blistered roofs, and we explain the reasoning in writing
The standards behind commercial roofing
Quality here is not a matter of opinion — it is written down. The commercial roofing work we do in Fontana follows published industry standards: NRCA publishes the Roofing Manual, the industry's reference for details and slope minimums, and Asphalt Roofing Manufacturers Association sets the shingle application and ventilation guidance the warranties reference. If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
Every commercial roofing project in Fontana gets the same attention, whether it is a single room or a full commercial job. We show up on schedule, keep the site clean, and stand behind the work — the estimate is free and there is no pressure.
