Roofers in Ontario, CA
Roof inspection in Ontario, CA is the smartest first call a homeowner can make when they suspect wind damage, see grit in a gutter, or simply haven’t looked up in a decade. The housing stock here is mostly wood-framed tract construction from the 1960s through the 1980s, with original sheathing and underlayment that has been baking under Inland Empire sun for forty or fifty years. We’re Gable Roof Repair, and we’ve served Ontario since 2016. We inspect first and recommend second. If you notice shingle granules collecting at downspouts or a ridge cap that looks uneven after a Santa Ana wind event, call (866) 650-8319 and we’ll take a look.
Why Ontario Homes Are Different
Ontario sits in the Inland Empire’s wind corridor at the base of the Cajon Pass, and that single geographic fact shapes more roof failures here than any other factor. When Santa Ana events funnel through the pass, they hit the older tract neighborhoods in the 91761 and 91764 ZIP codes hard, peeling back asphalt shingle tabs and lifting concrete tile on homes that were built to 1970s wind standards, not today’s. Roofers in Ontario fight wind uplift, not snow load. The dry heat cooks shingles from above while the gusts pry edges from the side, and the combination creates a failure pattern we see constantly: curl one year, crack the next, blow off during the next wind event, then water gets in at the next winter storm.
The housing itself compounds the problem. Most of Ontario’s single-family stock dates to the mid-century boom and the 1960s through 1980s expansion, with newer infill subdivisions mixed in along the 91762 corridor. The older homes are almost all wood-framed with asphalt shingle roofs, some with concrete tile. What concerns us most on those roofs isn’t the shingle surface, it’s what’s underneath. Original plywood sheathing and felt underlayment baked brittle for forty years doesn’t just lose its grip on nails; it can crumble when a repair crew steps on it. That’s why our Ontario inspections always check decking condition, not just shingle condition. A new layer of architectural shingles over failing sheathing is a five-year roof, not a twenty-five-year roof.
Styles & brands we work with






Our Main Ontario Services
Most Ontario homeowners call us for one of two reasons: visible damage after a wind event, or an aging roof that’s reached its final years. Here’s how each service works in this city.
Roof Repair in Ontario
Repair work in Ontario usually means wind-lifted shingle tabs, blown-off ridge caps, or tile that cracked under foot traffic or falling eucalyptus branches. We match the existing material, whether that’s an Owens Corning architectural shingle or a concrete tile profile that’s still in production. The job is straightforward: we inspect to find the full extent of the damage, then we fix what’s compromised and verify the surrounding area is sound. On 1970s tract roofs, we often find adjacent shingles have lost their seal and are one gust away from coming off too, so we address those while we’re up there. See Roof Repair in Ontario for details.

Roof Replacement in Ontario
When replacement is genuinely the right call, Ontario’s wind exposure changes the job. The local building department scrutinizes wind-uplift nailing patterns on re-roofs, and we follow those requirements because they’re what keeps a new roof on the house during the next Santa Ana. We work with seven major manufacturers, including Atlas and IKO, so material choice is real, not a single-brand pitch. We strip to the deck, replace damaged sheathing, install the underlayment and shingles to manufacturer spec, and handle the permit and inspection. Read more at Roof Replacement in Ontario.

Roof Inspection in Ontario
Roof inspection in Ontario is a standalone service with us, separated from any sale. We’ll walk the roof, document what we find, and give you an honest assessment of what the roof actually needs, whether that’s a repair, a replacement, or nothing at all right now. Given the dry heat, the wind corridor exposure, and the age of Ontario’s older tract homes, we recommend an inspection after any significant Santa Ana wind event and at least once every two to three years for roofs past their fifteenth year. Our Roof Inspection service was built for exactly this: diagnosis first, recommendation second.

Ontario’s wind corridor pushes repair costs up when damage is widespread across multiple slopes, and homes with original 1970s decking often need plywood replacement that adds to the total. Our estimates are fixed once we measure the roof and specify materials, so the number we give you is the number you pay, no change orders at the end.

FAQs About Roofers in Ontario
We schedule inspections and repairs within a few days of your call during the wind season, and we prioritize roofs with exposed decking or active leaks. The good news is that wind damage usually holds off on leaking until the next rain, but the sooner we secure loose shingles, the less the next storm can get in. Call (866) 650-8319.
Yes. Ontario’s building department requires permits for re-roofs, and our replacement process includes pulling the permit and scheduling the inspection. For repairs, most minor work doesn’t require a permit, but we’ll tell you if your specific job does. We handle the paperwork so you don’t have to sort out city requirements on your own.
We do. Most of our Ontario work is asphalt shingle repair and replacement on the older tract homes, but we also repair and re-set concrete tile on the homes that have it. The material doesn’t change our process: inspect first, recommend what the roof actually needs, and match the existing system when we repair. Call (866) 650-8319 to schedule a free estimate.

What Ontario Customers Say
"Full replacement after the hail. They handled the insurance adjuster meeting, documented everything, and I did not have to argue with anybody. Crew was here three days and the yard was cleaner when they left than when they started."
— Travis Thompson"He told me my roof had another five or six years in it and I should not replace it yet. He was standing there with a quote pad in his hand. That's why I'll call him when it's time."
— Lucia Salazar"Flashing where the roof meets the chimney had never been done right by the original builder. He rebuilt it properly with step flashing instead of just running a bead of caulk over it like the last two people did."
— Andres Martinez
